WRT160N dhcp reservation causing lease time weirdness with WUSB300N

I just purchased these two devices and things seem to be working OK but when I try to reserve a dhcp ip for my desktop PC which is connected to the network with the WUSB300N, the lease time on that ip address goes down to 1 minute. It ends up constantly dropping and reconnecting the address. If I remove the reservation, the WUSB300n goes back to getting a normal 24 hour lease. This is not an issue with any of the other wireless devices on my network. I have a Macbook Pro, an iPhone and a PS3 all with reserved dhcp ip addresses and their lease times remain at 24 hours.
I'm assuming there must be some setting for the WUSB300n that could take care of this but I can't find it. The desktop PC is running Windows Vista 64 bit home premium. The installation of the WUSB300n didn't exactly go smoothly. Every indication during installation was that of failure to install correctly. No linksys utilities were installed and Vista reported the driver installed but the adapter wasn't working; when I rebooted the wireless usb adapter did work. Of course that's not uncommon, requiring a reboot for a driver to initialize but nothing in the installation indicated a reboot would be necessary and typically a reboot isn't necessary for USB driver installations. In addition, the driver disc that came in the box with the WUSB300n didn't work so I used the driver package available from this site.
I can live without the dhcp reservation but to best manage my home network I'd like to take advantage of this option.
Thanks

Greetings - I'm actually having the exact same problem with my WRT160N. I bought the router in December 2009 and utilized one reservation for a network printer. It worked fine, and the reserved IP address would show up in the DHCP Client List of the router configuration page with the correct lease time remaining. More recently (May 2010), I added a 2nd reservation for a network hard drive. This is when the problem began occurring, and it impacts both the network printer and network drive. The reserved IP address leases will appear in the Client List for (what appears to be) a random amount of time, then at some point changes to one minute and counts down until it expires off the list. The devices continue to work with their IP addresses after they erroneously expire off, but this inconsistent behavior suggests there may be a problem with the router's DHCP reservation functionality.
To clarify, I'm not using the WUSB300N, my problem is the one identified with the WRT160N. My reserved devices are a PC being used as a shared network drive (with an integrated Intel NIC) and an HP C6180 printer with built-in NIC.
I utilized linksys.com online technical support chat, and she had me re-flash to the latest firmware. This ultimately did not solve the problem. Any troubleshooting ideas?

I use a DSL to connect to the internet. The modem is a Westell C90-810030-06. Two things happened in connection with the fail. I upgraded the firmware in both my Time Capsule (connected to the DSL) and the Airport Extreme (connected to my printer--used to extend the network). I also upgraded my Colof Nook to the Android Faux Tablet version. I can't imagine that that is creating some sort of mismatch.
I have now downgraded the firmware on the Time Capsule to 7.4.1 which is what I had before. Fortunately, I found the trick to downloading the older airport utility to find the older firmware. All the older versions disappeared from my computers.
I still have the same problem. Wifi works fine. If a second device connects to the wifi, then it works fine, but the first no longer has a connection.
And my Airport Extreme is not working at all. It cannot be seen by the computer. I tried resetting it. I'm going to connect it by ethernet and downgrade the firmware on it.
I appreciate any help. This is so frustrating.

Vlan Select and DHCP reservations on a WISM with code 7.0.116.0

We went to using vlan select this semester and have had a couple of issues where clients (printers) wont pull their reserved ip from dhcp. From what I've read vlan select can handle static ip addresses but can it handle dhcp reservations if the current vlan selected in the round robin function is not the vlan that the ip is reserved in?

George,
Are you talking about a dhcp mac reservation for a device on all vlans in the bundle? If so, you can... The issue I ran into is that clients had to connect to a wireless printer and a wireless projector and they connected to it via ip address. So it became a nightmare with users. They just kept complaining that it works some days and other days it doesn't. Some devices were powered off after it was used. It would be nice if you can import a list of Mac address and specify what interface it is allowed on... That would make it easy.

Express and extreme both "n" with static vs dhcp reservations.

Good day, and thanks for reading.
I have an express that I have configured to "extend my wireless network" with my extreme. This is all setup manually, with no internet connection needed. everything is static and I am just using the wireless and switch of the routers.
I have 4 electronic components that have static IP addresses _and_ I have added the mac addresses to the DHCP reservation list as well.
I would prefer to leave everything with just the manual addresses in mac access control, however- the apple log does not show the connections for these components with static addresses. However, they do show up on the log as connected in the DHCP client log when I am using DHCP only.
My questions are;
1. Does it hurt performance on the routers to have the mac addresses filled in on both the DHCP reservation list, and the mac address control list?
2. Do I need to have all the mac addresses for my connected components on both the extreme and the express or, can I just have them inserted on the extreme- and are there any conflicts that can arise with having them coded on both routers?
I just want to be able to see the connections on the log, and currently it will only show them if I am using DHCP.
Thanks you.

Hello chrisinoswego. Welcome to the Apple Discussions!
1. Does it hurt performance on the routers to have the mac addresses filled in on both the DHCP reservation list, and the mac address control list?
No.
2. Do I need to have all the mac addresses for my connected components on both the extreme and the express or, can I just have them inserted on the extreme- and are there any conflicts that can arise with having them coded on both routers?
When employing MAC Access Control, the MAC addresses would need to be entered in each base station. The only conflict that I am aware of is when the (in this case) two MAC lists are not identical.

Automatically renew DHCP when lease time expires from my ISP

hi guys, just bought a WRT54G v8 and I would like to know how I could setup the router to renew its lease time from my ISP. My Cable Internet provider has 24 hours of lease time for every subscriber and whenever my lease time expires, the router is not renewing it automatically. I have to access the router and manually release and renew DHCP. Any help would be appreciated. Thanks

hi... go to www.linksys.com/download and dowload the firmwarefor the router, logon to router's setup page and try reflashing/upgrading firmware on the router...after reflashing firmware on the router, try resetting it back to factory default settings and reconfigure it according to ISP settings, reduce MTU to 1458...check whether it makes any difference or not.

DHCP reservation BAD_Address and Mac Address changes.

Ok. I understand about Bad_Address and the things that can cause it. That said, I am using Window 2003 and we are running DHCP. Yesterday we had a series of short power outages. Some were right after the other (1 or 2 seconds) others
were 10 to 40 seconds in between. The server (of course) has a UPS and so does most of our infrastructure (switches etc).
But it seems that one type of Printer that we have, were all switched to bad_address and they could not pick up their reserved IP address. Some of them seemed to remember their IP and are still functional, even though their reservation says bad_address.
I assume they will fail either at lease renewal or the next time they are power cycled. What surprised me was that these bad_address entries' reservations were changed to have an invalid MAC address.
All of them start with a 0 or a 1 and are only 8 characters long. 0401150a, 1701150a, 1901150a, hmmm. i see a pattern forming. They all have unique first 3 characters, but everything after that is 1150a. That led me to figuring
out what this number is. It's an inverted hexadecimal representation of the ip address that is being complained about. Why would the DHCP server replace the MAC with this convoluted string? Is this covered in any manual?
I am pretty sure it's not in the DHCP RFC.
Not sure why it was having the problem, unless somehow the printers were powering and made the DHCP request then discovered that the old lease information was kept somehow (remember, some of the outages were very brief) after the request had gone out.
But that, and nothing else I can think of makes sense. And it only happens on one model of our printer. At least so far. And this isn't the first time we've seen it happen this way.
Any ideas appreciated.
Chris

Hi Chris,
Firstly, it seems that the Unique ID of the DHCP Reservations are inverted to the IP addresses in hex. And, the most possible cause is IP conflict.
For example:
0401150a -> 04 01 15 0a (hex) -> 4 1 15 10 (decimal) -> 10.15.1.4 (IP address)
Meanwhile, I agree with the possible cause as you said, however, would you please kindly let us know the following:
1. How many DHCP Servers do you have? Or, is the DHCP Server multihomed?
2. Do the printers have multiple NICs?
3. Are the printers both statically configured and have DHCP Reservations in the DHCP Server?
4. DO other DHCP clients in the same scope have the same issue?
5. Is there any trace in DHCP log?
In addition, if Conflict detection is enabled in your DHCP Server, please disable it and see how it works.
Also, please check if you can get some clues from this TechNet Thread:
DHCP server bad address issue
In addition, as the issue only occur with the same model of printers, it is worth to contact the vendor for their insight on it.
Hope this helps.

E4200 : DHCP Reservation not showing anything !?!

Hello,
When I'm in Setup -> Basic Setup -> click on DHCP Reservation, I don't see all entries I've created earlier but computers that connect still have the correct IP address on the network; I don't know if I can create additional entries if nothing appears, what should I do ?
When I go to Status -> Local Network -> DHCP Client Table the list is blank but some computers are connected to the network
I'm using firmware 1.0.01 build 10 Feb 21, 2011, language = English, Firefox 4.0.1
Rebooting the router doesn't change anything, I can't see connected LAN equipment and DHCP Reservation is empty despite the fact I've created entries.
Together with the "Access Restriction" which doesn't allow to block a computer from 10pm => 8am unless you create 2 rules + various issues with attached USB + 2.4Ghz signal that is far from optimal (never able to achieve more than 144-N-Mbps) and I ask myself if I will not contact the store where I purchased this unit and ask a refund (and buy something else from another brand...)
It's the first time I buy a Linksys equipment and very disappointed, support doesn't seem to be very serious
Thanks for any suggestion
PS: Where do I ask for a refund or something similar in Linksys site ? If nothing exists, I'll let the store where I purchased this unit now about the present post

Thanks for your answers
Today it works and I didn't reboot, restart or reset anything
I can see DHCP Reservation list + DHCP Clients Table
Same PC, same network, nothing restarted, reset, changed or added and now it works
Weird
I would not like to re-create everything in the DHCP Reservation List as I have 17 entries so far (and going to add 1 more...)
Apparently, if I can't see my list, I have to wait a few days

DHCP Reservation

DHCP reservations are nothing more than instructions to the server.The DHCP client protocol doesn't know anything about reservations. DHCP clients send their MAC address as part of the request and the DHCP server uses this address to find a matching reservation. If the server finds a match in the reservations it allocates the reservation address. If not then the server searches the existing lease table and allocates the first match there. If no MAC match is found then the next available IP address is allocated. The protocol doesn't proscribe how the "random" allocation is done, just that it come from the lease pool.Because the DHCP client doesn't know about this it then starts sending lease renewal requests at the 50% point in the lease.To unblock port 68, enable Bootp on your DHCP server. The Windows DHCP server works with both DHCP...

Hi,
I have a thin client device that receives an IP address from a DHCP server on Windows 2008. I created a DHCP reservation for the device to use 192.168.0.81 and confirmed that the IP address was assigned to the device correctly.
But I have been seeing packets are being blocked by firewall because port 67 from requesting device to DHCP server on port 68 does not allow by default rule on firewall.
My question is, even though the device receives the reserved IP address, why it keeps sending DHCP packets to its server? As far as I know, when DHCP reservation is used, there is no lease time allocated to the IP. Or does device send DHCP packets anyways regardless of reservation? If it does, how often does requesting device send the request?

DHCP Failover Address Leases

Just implemented 2012 DHCP Failover using the Hot-Standy model. I set the Maximum Client Lead Time to 1 hour.
My clients are getting the initial lease with an expiration of 1 hour. Then after the hour, they disappear from DHCP and DNS but they still have the address. Any ideas?

I am also having a similar issue after implementing DHCP Failover. I configured it with default settings (1 our MCLT, 8 day leases, %5 IP reserve). I tested the fail over and it worked. Clients received new addresses from the standby. I then started the
DHCP service on the primary and all seemed well. However, a short time later about a dozen hosts seem to have lost their DNS A records.
These machines have DHCP leases that began before the failover was tested and expire days after. They did not actually ever attempt to renew DHCP at this time (to my knowledge). I think this may be a bug or somehow related to the DNS configuration on the
scope. It is currently set to "Always update" and I may change to Dynamically update if requested, and test failover again.

C6300BD-202 - DHCP Reservations Faulty on this router!

It simply does not give out the right IP to reservation as seen in the screenshot. Firmware update urgently needed. Also, on basic view the blue boxes showing the connected device info disappears after about 10 seconds.

What frustrates me is I have given black and white evidence with the screen capture in the initial post proving the DHCP reservations are not being given out, simply ignored. You can imagine the havoc this causes trying to set up a home network. Its also kinda crappy that it doesn't show the netbios/dns names against the DHCP leases. My older Netgear R6300 does this.

Time capsule with USB printer stop to work.

Two months ago, I installed a brand new Time Capsule 2T. Initial configuration went without any issue.I installed an HP wireless printer and a second HP Laserjet to the USB port on time capsule. Everything was working well and suddenly the printer hooked on USB port stop working. Print job remains in the queue and nothing happens even using my MBP or using a PC connected to Time Capsule. The wireless printer is still working fine. So, I did a soft reset by pressing the button at the back of Time Capsule but it doesn't solve the problem. Both MBP and PC cannot connect to USB printer. The only way to recover printing capability is to unplug power on Time Capsule and re-plug it. In this case, MBP and PC could print. I don't know when this issue begins and I cannot predict when printing capability issue on USB printer will occur. I'm pretty sure this a Time Capsule issue or OS issue.
Couple things I tried:
- Uninstalled printer and re-added
- All drivers are up-to-date
- Time Capsule firmware is up-to-date
- MBP running OS X Mountain Lion with latest patches
- PC Windows Vista Ultimate with latest patches.
Any idea what could cause this?

Yes, your solution of the power cycle of the TC shows that this is caused solely by the poor networking ability of the TC. There is a flaw in the firmware that is causing the issue. The issue affects a number of things.. yours is just one example of it.
There is no solution. I cannot even give you a true work around using just the TC..
Best solution is of course to get a network printer.. usb is seldom designed for network usage. You can purchase an ethernet to USB print server but the cost of the item would be half the cost of the new printer. And useless item into the future. So consider carefully.. maybe time for a new printer.
In the TC do the following.
1. Reduce the firmware to 7.6.1 if you recently installed latest 7.6.3 that could be some of the issue.. it has proven less than great update. Hold down option key when you select firmware and you can downgrade.
2. Factory reset after you do 1. or do it anyway if you want to stick to the latest klugde firmware. But clean up the old settings by using new setup.
3. Use all names that comply to windows standard.
Short,, 10-20 characters should be plenty.. less than 10 also good.
No spaces..
Pure alphanumeric.
4. If the TC is set to main router, set the dhcp server to much shorter lease time. I suggest even 20min. The increase in network traffic for dhcp renewal will be tiny.. but it will keep ARP tables updated better than the full day used by default.
5. From the windows side make sure the TC is set to the correct workgroup under file sharing.. generally WORKGROUP.
6. If you still have issues.. and I think you may mitigate the problem but not resolve it doing the above.. a nightly auto reboot from an electrical timer.. crude but we have done such things before to fix crummy domestic level router to make them reliable.

Using TIME MACHINE with a TIME CAPSULE

There's often a bit of confusion about this terminology: +*Time Machine+* vs. +*Time Capsule:+*
_*Time Machine*_ is Apple software that performs backups, to an external HD, a Time Capsule, etc.; and also allows you to browse and restore from them. It comes with Leopard and Snow Leopard, but cannot run on any previous versions of OSX.
A _*Time Capsule*_ is a piece of Apple hardware that combines a wireless router and hard drive, that can be used for Time Machine backups and/or other data.
Most Time Machine questions & problems are not unique to Time Capsules. For those, or if you don't find what you need here, try one of these:

QUESTIONS
|
_*Q1. How do I set up Time Machine to back up to my Time Capsule?*_
|
First, set up your Time Capsule via +Airport Utility.+ Keep the name you assign to it, your Computer, and your network short (under 25 characters), and avoid embedded spaces, special characters, and punctuation (see item #P1 below for details). Make sure your Mac can connect via an Ethernet cable, if at all possible, as well as wirelessly.
The setup and first backup (of your entire system) will be much faster if you connect via Ethernet.
|
a. If the +Time Machine+ icon isn't already in your Dock, drag it there from your Applications folder. See below for more about it's use.
b. Right-click it and select +Open Time Machine Preferences,+ click the +Show Time Machine status in the menu bar+ box (see below), then click +Select Disk+ (on Leopard, this button will be either +Choose Backup Disk+ or +Change Disk).+
c. A list of possible destinations will appear. It should include your Time Capsule (with the name you gave it via Airport Utility), and may show other internal or external drives as well. Select your Time Capsule and click the +Use for Backup+ button.
d. A prompt for your name and password will appear. In some cases there won't be a Name field, but if there is, enter your short user name. Also enter the password you set up for the Time Capsule via Airport Utility, then click the Connect button.
e. A 120-second countdown to the start of your first backup will appear in the +Next Backup+ area of the TM Preference panel.
|
Note that this first backup will copy the entire contents of your system, except for a few things that are skipped automatically, such as system work files, most caches, your logs, trash, etc., and anything else you may have excluded (see #10 and #11 in the Frequently Asked Questions *User Tip,* also at the top of the +Time Machine+ forum). So it will be rather lengthy, depending on how much data is on your system, whether you're connected via Ethernet or WIFI, and if WIFI, how good the signal is.
You can continue to use your Mac while TM is backing-up, and you can even cancel a backup if necessary, but to make this first full backup as fast as possible, try not to overload your Mac or cancel the backup.
|
_*The Time Machine Icons in your Menubar and/or Dock*_
|
In the steps above, you dragged the TM Application's icon into your Dock, and clicked the +Show Time Machine status in the menu bar+ box.
For detailed info about them, see question #24 in the Frequently Asked Questions *User Tip,* also at the top of the +Time Machine+ forum.
+Go to Top+
_*Q2. How do I set up Time Machine to back up to a USB drive connected to my Time Capsule?*_
|
Mostly the way you set it up to use the Time Capsule's internal HD.
But first, attach the drive directly to your Mac, and erase and format it per the instructions in #5 of the Frequently Asked Questions *User Tip,* also at the top of the +Time Machine+ forum. Note, however, that it doesn't matter whether you use the +Mac OS Extended (Journaled)+ or +Mac OS Extended (Case-sensitive, journaled)+ Format, since Time Machine will put your backups in a sparse bundle that's case-sensitive. You cannot change that.
Unlike the Time Capsule's disk, you can partition the USB drive. That's highly recommended if you're going to be putting other data there, so the backups don't completely fill the disk (but be aware that Time Machine cannot back that "other" data up. See question #Q6 below).
If you're backing-up multiple Macs to the same drive, you can make one partition for each, but it's not as helpful on a network drive, because each Mac's backups will be in a separate sparse bundle. So you can let them share the disk or a partition.
Also note that if you've been doing backups to an external disk connected directly to your Mac, you cannot continue the same set of backups when you connect it to your Time Capsule. They are stored differently, and Time Machine will put them in a sparse bundle, alongside but *completely separate from* the backups made locally, and the first backup will be a full backup of your entire system.
Once the USB disk is set up the way you want it, use the setup procedure in question #Q1 above, but in step (c), select the USB drive/partition, not the Time Capsule's internal HD.
*RAID Sets connected to a Time Capsule:*
|
Time Machine will back up to a +Hardware Mirrored RAID set,+ also called +RAID 1,+ (sold that way, with multiple drives in the same enclosure). However, if you partition the +Hardware Mirrored RAID set,+ once you start using it with TIme Machine, you cannot change the sizes later and continue to back up to the same set of backups.
While you can connect multiple USB drives to a Time Capsule via a USB hub (a powered one is best), Time Machine +*will not+* back up to a +software Mirrored RAID+ set (where you combine the drives into a single volume via Disk Utility).
+Go to Top+
_*Q3. Can I use my Time Capsule for Time Machine backups and other data?*_
|
You can put other data on your Time Capsule's internal HD, but there are three major considerations:
Especially for things like photos and videos, access may be too slow for convenient viewing, and worse for editing. So test this a bit before you decide what to put there.
Time Machine cannot back-up that other data, so you'll need some other method. See question #Q6 below.
Time Machine will, by design, fill up all the space available to it, so there may be a conflict between the sparse bundle it puts your backups in, and the other data. There is a workaround, to "reserve" some space there, by creating a disk image of the desired size and storing your data there, but it's a bit cumbersome, and two Macs can't share it at the same time.
An alternative is to connect a USB drive to your Time Capsule. Then you can back up to the TC's disk and use the USB drive for other data, or vice-versa. But note that Time Machine cannot back-up the USB drive while it's connected to the TC (see question #Q6 below).
If you want to reserve space on the TC's internal disk, here's how:
|
a. Start the +Disk Utility+ app (in your Applications/Utilities folder). Click the +New Image+ icon in the toolbar (or select +File > New > Blank Disk Image+ from the menubar). If the little arrow to the right of the "Save As" box points down, click it so it points up.
b. Give it a name in the "Save as" box. This name will appear on the TC's disk, with ".dmg" appended. (Similar to the way the sparse bundle containing your Time Machine backups appears, with ".sparsebundle" appended).
c. Click your TC in the sidebar. It may take a few moments for Disk Utility to recognize it, and show it in the center pane.
d. In that center pane, select the blue Share folder for your +Time Capsule+ (you may need to scroll down, or enlarge the window, to see it). Once selected, you'll see any existing disk images in the right pane.
e. Give the Image a name. This name will appear on your desktop and/or Finder sidebar when you mount the .dmg by double-clicking it, if you have the +External Disks+ box checked in +Finder > Preferences > General+ or +Finder > Preferences > Sidebar.+
f. Select the Size for the amount of space you want to reserve, either one of the pre-sets or Custom which allows any size. Avoid taking all the remaining space for the disk image, as Time Machine needs a bit of room to operate. Also note that if very little space is left, it will begin deleting old backups very soon, to make room for new ones.
g. Select the desired Format, probably the default of +Mac OS Extended (Journaled).+
h. If you want it encrypted, select the desired type.
i. Select single partition, either GUID or +Apple Partition Map.+
j. Select +Read/Write disk image+ for Image Format.
k. Click the Create button. The larger the image size, the longer this will take.
|
When complete, the new disk image will be automatically mounted on your Mac's desktop, ready to receive the files you want to move into it. (When you first open a disk image, there may not be a sidebar and/or toolbar; if so, select +View > Show Toolbar+ from the Finder menubar.)
To access this disk image from another computer, you must first eject it from this one, since only one can mount it at a time. Otherwise, the other one will see a message that the disk image is "Temporarily unavailable."
Note that you may be able to change the size of the disk image later, via +Images > Resize+ from the Disk Utility menubar (while the disk image is not mounted or selected in Disk Utility's sidebar).
+Go to Top+
_*Q4. My Time Capsule is too small to back-up my Mac(s). Now what?*_
|
You can attach a USB drive to your Time Capsule. Then you can back up to the USB drive instead of the Time Capsule's internal HD. If you have multiple Macs, you can back some up to the TC's internal drive, and others to the USB drive.
If you need even more space, you can connect multiple USB drives via a hub (a powered one is usually best), and back up different Macs to each. What you cannot do, however, is have one Mac's backups continue from the Time Capsule's internal HD to a USB drive connected to it, or have the backups for any one Mac "span" two drives.
The exception is, you can connect two (or more) drives that are in a +concatenated RAID+ set (sometimes called +RAID 0).+ In that configuration, all the drives in the set are treated as a single volume (see +Concatenated RAID+ in the Help for Disk Utility for details). This configuration may cause some other difficulties; once they're in a RAID set, you cannot connect any drive to your Mac separately -- it's all or none. And if one drive fails, you risk losing everything on all the drives in the set.
See question #Q2 above for setup instructions for backing-up to the USB drive.
+Go to Top+
_*Q5. Should I delete backups? If so, how?*_
|
It depends on exactly what you want to do, and why.
Under normal circumstances, you shouldn't have to delete anything. TM automatically "thins" (deletes) backups every time it does a new backup, on the following schedule:
"Hourly" backups after 24 hours (except the first of the day, which is a "Daily" backup).
"Daily" backups after a month (except the first of each week, which is a "Weekly" backup.)
"Weekly" backups are kept until TM needs the space for new backups; then one or more of the oldest weeklies will be deleted.
However, TM will never delete the backup copy of anything that was on the disk being backed-up at the time of any remaining backup. So all that's actually deleted are copies of items whose originals were changed or deleted before the next remaining backup.
But if you do need to delete backups, here's how:
To delete individual backups, or all backups of selected item(s), see #12 in the Frequently Asked Questions *User Tip,* also at the top of the +Time Machine+ forum.
To delete everything on the Time Capsule's internal HD, use +*Airport Utility.+* Select +*Base Station > Manual Set-Up+* from the Menubar, then Disks in the tool Bar, then Erase.
To delete everything on a connected USB drive/partition, you can delete via the Finder, but that may take a very long time. It may be faster to disconnect it from your Time Capsule, connect it directly to your Mac, and use Disk Utility (in your Applications/Utilities folder) to erase the disk/partition.
To delete all the backups for one Mac, without disturbing anything else on the Time Capsule's internal disk, open the TC via the Finder and delete the sparse bundle associated with that Mac.
To delete all the backups for one Mac, without disturbing anything else on a connected USB drive, either open the USB drive via the Finder and delete the sparse bundle associated with that Mac, or disconnect the drive from the TC, connect it directly to your Mac, and delete the sparse bundle from there.

_*Q6. How do I back-up my Time Capsule and/or attached USB drive(s)?*_
|
That depends to some extent on what you want to back up, and where it is.
It's generally not a good idea to try to back-up your Time Machine backups. If there's a problem with them, it will be copied to (and perhaps magnified on) the copy.
A better solution is probably to use either Time Machine or a different application to make separate, independent backups of your Mac, to a different destination. A portable external hard drive is great for this; you can periodically connect it to your Mac, make a backup, then take it to a secure off-site location, so you're protected against fire, flood, theft, direct lightning strike on your power lines, etc. If you use Time Machine for this, you'll have to use the disk selection process each time you want to switch, via +Time Machine Preferences.+
Many folks use the CarbonCopyCloner or SuperDuper! apps to make "bootable clones" of their internal HD to an external HD. While these usually don't have "archived" copies of previous versions of things you've changed or deleted, you can boot and run your Mac from them if your internal HD fails. Your Mac may run a bit slower, but it will be usable. Both are easily found via Google.
Since Time Machine cannot back up your Time Capsule's internal hard drive, or a USB drive connected to it, if you have other data there, you'll need a different method to back up that other data.
In a pinch, you can disconnect a USB drive from your Time Capsule, attach it to your Mac, and copy or back it up that way.
|
There is a procedure that will let you "archive" the TC's internal disk to a USB drive connected to it.
But it's not quick, since since the data must be read from the TC's internal disk to your Mac, then sent *back through the Time Capsule* to the connected USB drive. And it's "all or nothing" -- you can only use this procedure to copy the entire contents.
All users will be disconnected from both the internal HD and the connected USB disk (but the network will remain usable).
Attach a USB drive with at least as much free space as the total amount of data on the TC's internal HD (see #5 in the Frequently Asked Questions *User Tip,* also at the top of the +Time Machine+ forum, for formatting instructions).
Turn Time Machine "Off" via +Time Machine Preferences.+ Stop all processes that may be accessing the Time Capsule's disk. If possible, connect your Mac to the Time Capsule with an Ethernet cable -- it will still be slow, but faster than WIFI.
Then follow this Apple procedure: Using AirPort Utility 5.3.1 or later to make a copy of the Time Capsule disk.

PROBLEMS
|
_*P1. The Backup disk image could not be created.*_
|
Oddly enough, Time Machine can be rather picky about the way certain things are named.
Check your +*Computer Name*+ at the top of the System Preferences > Sharing panel.
It must not be blank; it should not be more than 25 characters long; and you should avoid punctuation, spaces, and special characters.
After changing it, click the Edit button and make the corresponding change to the +*Local Hostname.+*
If that doesn't help, apply the same rules to the name of your Time Capsule and Network, via +Airport Utility.+
+Go to Top+
_*P2. Time Machine could not complete the backup .. sparsebundle could not be accessed. (Error 109).*_
|
The sparsebundle containing your backups is corrupted.
Try Repairing it, per #A5 in the Time Machine - Troubleshooting *User Tip,* also at the top of the +Time Machine+ forum.
If the sparsebundle is on your Time Capsule's internal HD, and Disk Utility can't fix it, your only option is to delete it (or erase the TC's disk), and let Time Machine start over. You may be able to prevent this from happening again by changing the names per problem #P1 above.
If the sparsebundle is on a USB drive connected to your Time Capsule, and Disk Utility can't fix it, it's possible a heavy-duty 3rd-party +Disk Repair+ application, such as +Disk Warrior+ can. (You'll have to connect the drive directly to your Mac.) These are not cheap, and there's no guarantee they can fix it. Be certain whatever you use is compatible with your OS. For Disk Warrior, you need at least version 4.1.1 for Leopard, 4.2 for Snow Leopard.

How to configure Airport Time Capsule with IP Camera?

I have recently switched from a DLINK Router (DIR-655) to the latest 3TB Airport Time Capsule. The ATC works great, super fast etc...
However...
I had an IP Camera (Trendnet TV-IP572-WI) connected to my DLINK Router, using a Dynamic DNS account (dyndns) to access if from outside my home (i.e. from the Internet). The configuration on the DLINK was quite straightforward. (Virtual Server)
Question: How to do the same with Airport Time Capsule ? I had a look at the detailed settings menu in the Airport Configuration Utility. but cannot find anything like this (Virtual Server, Port Forwarding etc...)
Many thanks for your help !

What is the make and model number of your "modem"?
Most modems these days are actually modem/routers or gateway devices....which would require that the port forwarding be done on the "modem"....not on the Time Capsule.
If you did not see any settings for DHCP Reservations and Port Settings when you looked around in AirPort Utility, this indicates that the Time Capsule is likely configured to operate in Bridge Mode.......and it is your "modem" that is actually the router for the network.
Open up AirPort Utility again, click on the Time Capsule icon, then click Edit in the smaller window that appears
Click the Network tab at the top of the window
Check the setting for Router Mode.......which is likely set to "Off (Bridge Mode)"
Is it?

2 different lease time on same scope

Hi, is it possible to add 2 different lease time on same scope.
I have server and workstation on the same scope and I want to give the servers longer lease time, than the workstation.

Hi
It is possible to achieve this in the Windows 2012 and higher versions of DHCP Servers using the feature of DHCP policies. You can create a policy within a scope. In that policy you can specify the type of clients you want this policy enabled for. The type
of clients can be differentiated based on
MAC Address
Vendor Class
User Class
Client Identifier
Relay Agent Information (and its sub options – remote id, circuit id and subscriber id)
in DHCP Server 2012
and based on FQDN along with above in DHCP Server 2012 R2.
Once the policy has been created you can set the lease time for the policy as per your needs. For more details you can look at the blog post entry below.

WRE54G version 3 uses all available DHCP connections causing all wireless connectivity to fail

I couldn't find this problem via search so i've started a new thread. Here is my problem.
I have configured my WRE54G and everything seems to be working great, a Wireless connection that was LOW is not Excellent.
a. I can connect to my router: 192.168.0.1 (WRT54GC firmware 1.05.7)
b. I can connect to my range expander: 192.168.0.11 (I changed the IP, firmware 3.01.01)
c. The Range Expander has the same SSID as my router and has the same WEP key too.
It seems that the range expander will eventually use all of the DHCP connections that I have configured for my router to allow.
I have the DHCP lease set to 30 minutes but when i look in the DHCP client list I see clients with 2 day leases, these are all the MAC Address of the Range Expander. Currently 5 of 7 connections are the Range Expander. Eventually it will consume all connection and I won't be able to connect.
On my wireless router I have MAC address filtering set up and only 4 MAC addresses are added to the "allow" list.

DHCP lease time on the router is 30 minutes.
It appears that the clients, specifically the only wireless laptop on the network, drops the connection and when it reconnects it gets a new lease and IP address. This happens many times until all IPs are in use. I don't know why the lap top drops the connection when the signal strength is excellent.
I have seen the MAC address of the Client in some cases but the majority are the WRE.
I've linked to some pictures of the router set up, the DHCP client list, and the basic WRE setup. There are only 3 wireless devices in my home, 1 laptop, 2 iPhones. I guess a neighbour could be trying to connect but I do have MAC address filtering turned on so only included MAC Addresses can connect.
I guess I could always update the firmware but I only want to do that if it will fix this issue. I tried the live chat today but I didn't have access to my home network so there wasn't much that we could do.
