Getting invalid IP address with Time Capsule in new Comcast setup

Today I just got hooked up to Comcast. I was using Qwest. I have a Arris TM722 cable modem that is going to a switch. One of the connections in the switch comes to my office. From the port in the office I have a Ethernet cable going to my first generation Time Capsule. With a cable from the TC to my laptop I can get online and the light on the TC is green. My IP address on my laptop is 1xx.xx.xxx.xxx. This is the same numbers if I hook up the laptop directly from the cable modem.
In the Internet tab in Airport Utility I have Connection Sharing set to "Off (Bridge Mode). DHCP is set to manually. If I had DHCP enabled I am not able to get online using a Ethernet cable.
I have Lion 10.7.2 on the laptop and the firmware is 7.6 on the TC.
When I connect to my wireless network that is set in the TC I receive an invalid IP address 169.xxx.xx.xxx.
I have reset the cable modem and TC twice and still cannot get a vaild IP address when I connect wirelessly.
Any suggestions on how I can get this to work would be highly appreciated. I had no problems wirelessly when I used Qwest DSL service.

When you had Qwest, you likely had a gateway device, which is a combination modem/router in the same package. If my guess is wrong here....you need to pretty much ignore everything else below.
Bridge Mode would have been the correct setting for the Time Capsule in this type of configuration since the Qwest device was handling DHCP assignments for all devices on the network. The Time Capsule was simply passing through that information to connected devices.
It appears as if you now have a simple cable modem.....which can deliver only 1 IP address. Then you have the cable modem connected to a switch. You cannot insert a switch between a simple modem and a router (Time Capsule). (You can if you have a gateway device).
The switch must come after the Time Capsule, not before the Time Capsule in this type of setup.
The Time Capsule is getting the IP address from the cable modem via Ethernet and passing it through in Bridge Mode when you connect a computer using Ethernet.
In order to connect the computer using wireless, you would need another IP address. But.... the cable modem is already delivering the only IP address that it can provide, and that is the Ethernet connection for a device.
My suggestion would be to completely reset both the modem and Time Capsule again and then connect the modem directly to the Time Capsule.....not to the switch.
The Time Capsule should be configured to "Create a wireless network". When it does this, it will also choose the Connection Sharing setting of "Share a public IP address" because it is now the main router that must supply the DHCP info and IP addresses to the network.
The Time Capsule is going to supply IP addresses that look something like 10.0.1.2 etc. to connected devices on the network.

Invalid IP address on time capsule 3rd gen

I can connect to the internet via the modem but when I try to connect via the time capsule (both wired and wireless) AirPort Utility tells me 1) I have an internet connection problem: invalid IP address adn 2) I don't have DNS server address
Anyway to fix short of restoring the from original settings?
thanks

It sounds like you are using Lion with v6 utility.. and that is at least partly the cause of the trouble.
Download and install 5.6 if you use Lion.
http://support.apple.com/kb/DL1482
Now you need to decide which device will be the main router.. as there should be only one router in the network.. either the modem has a router.. most do now.. or the TC will be the router.. don't use two. Something has to be bridged.
So if you have cable modem.. pure modem that is excellent. TC will be the router.
If you have adsl it is generally also a router.. that can either be bridged or you can run the TC as pppoe client.
Tell me exactly what you have for broadband.. and if it is working as router or not.
Assuming it is working as router.. you need to bridge the TC.
Reset the TC to start.. we want to get a fresh go at this.
As stated.. in the 5.6 utility.. go to manual setup.. select the internet tab.
On the bottom of the page select connection sharing.
Select option.. off, bridge mode.
Update the TC.
It is best to do this with ethernet.. direct to the TC.. you don't need any other connections to set it up.
But if you normally use wireless then setup wireless as well.. much easier when connected NOT by wireless to setup wireless. Otherwise it is like sawing off the branch you are sitting on.
I recommend wireless name.. short, pure alphanumeric with no spaces.
Separate name for 2.4 and go to the advanced wireless page and give a different name to 5ghz.
Lock channels to 1, 6, or 11 for 2.4 ghz .. 5ghz does not matter so much.
Set wpa2 personal security with passkey.. 8-12 characters pure alphanumeric.. no spaces.
Once selected and updated.. plug the TC into the main modem - router with ethernet.
Connect I guess using wireless from the computer.

HT4628 Limit on the # of IP Addresses with Time Capsule?

I seem to only be able to connect 6 devices to my wireless network at one time, and I often have to reset my modem and Time Capsule to get something to connect. My internet service provider said it's probably a limit to the # of IP addresses through the Time Capsule. Is that true? Any other advice?
I have the 2TB Time Capsule with iMac, Macbook, iPhone, Xoom tablet, and printer that I regularly connect to it.
Thanks for your help!

Please review what we said previously.......
Assuming that the Time Capsule is configured as your router, the Time Capsule will provide up to 200 IP addresses unless you have changed the settings. You can adjust it to provide up to 250 if you need more than 200.
If the Time Capsule is in Bridge Mode to work with your modem/router, then it is up to your modem/router to issue IP addresses.
Your Time Capsule is not configured to act as the router for your network since you told us above that......
Airport Utility is set as "Router Mode: Off(Bridge Mode)".
Configure the Time Capsule Router Mode = DHCP and NAT if you want it to act as the router for your network.....not as a bridge.

Migration Problems with Time Capsule and New MacBook Pro

Hopefully someone on here can help with with this problem I'm having. I just bought the new 13' MacBook Pro this week from the store and I no longer have my old MacBook Pro. I have a Time Capsule with complete backups of my old MacBook Pro and I also have the internal hard drive from it as well.
I had installed the beta version of Mountain Lion on the old MacBook Pro and the new one still has Lion.
The problem is that every time I have tried to use the Migration Assistant (and I've tried 3 times now) my files and applications are getting messed up.
iPhoto won't open. It says that it needs to be updated but when I check to update it it says that there is no update needed.
I'm seriously about to beat my head against the wall because every time I migrate the data it takes about 12 hours. I'm thinking at this point that it might be easier for me to just swap out the internal hard drives in the units because it is possibly an issue with the OS' and wait until next month to try migrating to the new drive again after Mountain Lion is officially launched.

Bob,
I appreciate your honest and prompt response. I was VERY SPECIFIC when I told the sales rep I was hoping to use the Time Capsule with two different MacBook Pro's on different subnets (one is behind a firewall on a router, one is directly connect to a WAN side IP with no firewall) and the sales rep made a point of saying that the dual band feature would facilitate this connectivity which left me with the impression (obviously wrong) that the WiFi features of the time capsule could be used to communicate with multiple Macs regardless of their own networking configurations. (I have been configuring fairly complicated networks for 20 years and only bought my first Mac two and a half years ago; the second Mac is only six months old; the third will be bought next month.)
This isn't the end of the world for me... it does require reconfiguring my network and doing a lot of port tunneling for the box outside of the firewall in order to bring it inside as well as giving up some remote access redundancies (which were based on the ability to connect to both machines using VNC software which is port specific which means that it needed separate WAN side IP addresses).
Overall I love the Mac approach compared to the nightmare that was (is) Windows (although I do also run an Ubuntu Linux box just to keep me honest). That said, your sales reps do your products a HUGE disservice when they give glib and incorrect answer to what was, I believe in my case, a very specific and precise question.

Issues with Time Capsule or Home Network Setup

I have the following network:
{if this image does not come through well here is a link to one: http://daviddwight.smugmug.com/photos/i-WTzcHBn/0/XL/i-WTzcHBn-XL.jpg }
Bill of Materials:
2Wire DSL Modem (also set up making a wireless network)
Ethernet running from Modem to Apple Time Capsule (also making a wireless network)
Time Capsule hooked to 27" iMac (OS 10.7.2) via Ethernet
Time Capsule hooked to a powered USB Hub
2 printers connected to hub
2 external disk drives connected to hub
wireless devices are an xBox, 2 iPod touches, and iPhone, an iPad, a MacBook and an AirPort Express hooked to a Stereo
I have an AirPort Express I don't use
The iMac Time Machine uses the Time Capsule
Everything works except:
the AirPort Express music drops out often
but more importantly I want to have the MacBook use a partition on one of the external disk drives for its Time Machine storage - it always has trouble mounting the drive, it will crank for hours and then give an error
Every once in a while I get an error that says something like "another device already using this IP address"
I think I may have a problem with DHCP or NAT or something
Can someone help provide some advice

Nice pic!!
Is the imac and MBP using Lion?
Is the TC running 7.6 firmware?
Has the issue existed since you put this together or happened subsequent to firmware or OS upgrades?
To some extent what you answer to the above will alter the advice.. but I would try a network rearrange which I know is a real pain.. a lot of work and I cannot promise it will solve things.. but I would like you to run the modem in router mode and the TC in bridge. Set a very short dhcp lease on the 2wire.. 10min.. the renewal of IP will not affect network performance in signifcant way.. but will help keep arp tables up to date.
Use manual setup for wireless on the TC.. fix the channels and make sure security is set WPA2 with a decent passkey.. and set all the names of things (and passwords) to no spaces.. no special characters.. straight alphanumeric. Wireless bridging will handle fixed channel much better than auto.
This could all achieve nothing.. but it is hard to track the issue.
You should also study the log of the TC.. but it does not seem to report an awful lot.
Do any devices have static IP set? If not then the TC is not handling DHCP very well if you are getting duplicate IP addresses. That is why I want you to try something else as the main router.
For devices like the printers. I have to admit being surprised you can manage both printers. USB hubs are a bit notorious for being a mixed bag.. if things go wrong with external USB drive I would be looking at finding a more compatible powered hub. Since these a cheap anyway.. it is finding one that agrees with TC or AEBS.. do a google search for what people are using.. again nothing might fix the problem.. but if you try something different.. hopefully with a different chipset.. it helps narrow the issue.
BTW plug the hug into the Mac and your system profiler will show lots of info about the USB device.

When doing a restore with Time Capsule, I get -8003 error; restoring nothing

Hi,
When doing a full restore with Time Capsule, I get -8003 error; restoring nothing. This happens with all recent backups. Also after doing a verify/repair of the TimeCapsule disk.
This is a dissaster for my originals (my Ableton Live projects). I am very dissapointed in TC and TM at this moment, because I trusted my backup system in combination with my MBP fully.
Please help?
Best regards, Tom

Hi Pondini,
Sorry for the late response, but the problem was something else and were two separate ones.
Somewhere along the way the TC backup couldn't find backup to the original TC volume, that's why I let TM backup towards my user volume named 'Tom'.
When I wanted to restore the root of my drive when selecting the diskname and 'Restore' in any point in time, this resulted in error -8003 in the activated TimeMachine.
Then I tried to do it via the recovery OS and even via the original OSX DVD. Both not enabling me to select the TC volume named 'Tom'. Then I remembered that I first backed-up onto the original 'TimeCapsule' volume/partition. When I copied the sparsefile to the 'TimeCapsule' partition, I was able to recover the entire disk using the recovery OS.
All my files are backup and I am a happy Mac user once again :-)
Thanks & Regards, Tom

I connected my Canon printer to time capsule, and can print OK. However, I can't get the printer scanner to work. How do you set up the scanner with Time Capsule?

You cannot use USB. It has to be a network capable printer.. is it?? You did not indicate how it is connected.. but by wireless or ethernet then scanning is possible otherwise not.

Setting up new HP Laserjet CP1525nw wirelessly with Time Capsule

Im having issues setting up my new HP Laser printer via wirelessly with Time Capsule. I have tried with the Wireless Client Setup
Assistant but cannot get it to work. Any help or suggestions would be appreciated. Thanks

I tried to get the CP1525nw set up on my computer here at the office and found, much to my chagrin, that the CP1525 is not supported under 10.7 and retroactively not supported under 10.6. The way that I have found to get around the issue is to connect it wirelessly via a static IP address and use a generic postscript driver. I'm hoping that they will release a driver to Apple soon, but until then, generic is the only way to go and I have not found any print quality issues.

Window 7 with Time Capsule

I keep getting an error (86) when I try to connect my Time Capsule with my PC that's using Window 7!
The error message keeps telling me that the password is not correct.But the Time Capsule is working fine with my Mac Pro and another PC that's using XP.This means the I can locate my TC disk with my Mac Pro and the PC with XP...but not on the Win7 computer!!
Does Win7 works with Time Capsule or not......I've read many info in this forum about Win7 and Time Capsule...but it's kinda confusing...cos it just seem like Win7 won't work wit TC......
Any conclusion or solution on this ...many thanks!!

a disk image of the backup on my desktop which disappears when Time Machine is finished
Yes, that's normal, TM only need to mount TC during the backup, it will be unmounted after backup is complete.
Plus there is only one file on the Time Capsule drive called XXX.sparsebundle
That's again correct. The file structure of the TM+TC backup is different to the TM+External HD. The sparesbundle is specially designed to be mounted over network, and the name of the sparsebundle file contains the MAC address of the computer that's created it. So that it can be identified by TM later.

Clear net connectivity with time capsule/home network

So Chicago has a new ISP - Clear. It is a wireless provider that boasts download speeds up to 12mbps. I have been using ATT DSL elite pro with time capsule as my wireless hub. I have extended my network via airport express and have two that power speakers/home entertainment system.
I have it up and running and connected directly from their router to my iMac. I would like to attach the motorola wireless router to my current home network that runs between the timecapsule and two airport expresses.
Any help would be appreciated. As well your opinions on choice of wireless ISPs vs home dsl line.
Thanks
Jenn

From your description, it sounds like you could swap the Clear modem and the AT&T modem/router. Power down your entire network for a moment. Then start the Clear modem first and let it run for 3-4 minutes, then start the Time Capsule, then Expresses and computers.
If you get a blinking amber light on the Time Capsule, check your settings as follows using AirPort Utility. It's located as follows: Hard Drive > Applications > Utilities > AirPort Utility
Click Manual Setup and then click the Internet icon at top of the setup page
At the bottom of the next page, look for the Connection Sharing setting. If I understand the Clear info correctly, you would set this to "Share a public IP address"
I notice that Clear has online tech support, so you make need to refer to them as well. Please post back on your progress.

ADSL Broadband With Time capsule

Hello could someone please help me?
I currently have ASDL Broadband using a netgear modem router that i want to remove and use the Time capsule, can this be done by pluging the phone line in or do i need to get a modem for the time capsule?
cheers steve

You can use either an Ethernet ADSL Modem or a combined ADSL Modem/Router.
The best option is an Ethernet modem such as the X-Modem or similar as the Time Capsule is already a router and it works well with things like iChat AV without any extra configuration.
Alternatively you could use virtually any ADSL Router and configure the Time Capsule as a bridge. The downside to this sort of set-up is rather than using the TC as a router you are having to use the ADSL router to do things like sharing and hand out DHCP addresses. This means you may have to make additional configuration settings on the router such as port forwarding or modifying firewall rules for things like iChat AV to work.
Either way will get you on-line with the TC.

MacBook freezes with Time Capsule

Hi all,
I switched from PC to mac and am very happy with that decision. I do have one recurrent problem, with Time Capsule and Time Machine and can't find anything in the manuals that tells me what the problem is.
My TC is not being used as a router, as my laserprinter doesn't have a USB, so I kept my wireless router to be able to continue printing from all machines at home and connected my TC to the router, giving it a fixed IP address within my home network. When it's on, it shows up in as a shard disk in finder and I can easily write files to it from all machines.
However, when I launch Time Machine, using the TC as the back-up disk, there is a small window saying "Connecting to server" and then my computer freezes and so does the TC so it seems. I've let this run for a couple of hours, but nothing changes. The only thing left to do is to turn off my computer.
I do realize that the above configuration is not what is recommended, and I assume there is some interference with the Airport trying to connect to the TC as well as to the router, even though Time Machine is set up with the TC with its fixed IP address.
I've been on the phone with an Apple person, but we were unable to fix this. I'm getting a bit desperate (and irritated) here. Any suggestions?
Thanks,
-Maarten.

Dear Bob,
Thank you for your answer. The procedure you suggested did work in so far as it found the disk and started the backup, but even if I had made a first backup on the disk a while ago (doing it with the disk directly connected to my computer as suggested by the Apple expert, rather than via the router), it took all night and still wasn't finished. The problem is that I cannot do anything on the computer while TM is running, programs will not start up, it even doesn't react to the keyboard. The only thing I can do is to turn off the computer. Given that I need my computer for work, I cannot afford it not to work
This is really frustrating: I know it should work (a friend of mine makes back-ups every hour with TM on a regular external disk, not a TC), and here I am with expensive (and nice) material, and it just doesn't work and I have no idea why.
Thanks again for any suggestion.
-Maarten.

Problem with Time Capsule after backup session

I have a problem with Time Capsule after a backup session. Our two Macs (on Maverick) loose connection with the station and the only thing that seems to help is unplugging the Time Capsule and starting it again! After the next backup session the same thing happens again. The Macs seem not to be able to hold on to the connection and continually loose it. The iPhones and iPads that we have (4 units) are not affected - it is the Mac Mini and Mac Powerbook that experiences this problem!
I would be grateful for your help!

This is standard Mac issues and has been a bug floating around since Lion.. it hits some people worse than others.. but once it starts it is awful hard to get rid of.
Just to confirm the connection to internet is not a problem?? Just the hard disk drops out?
I recommend you
1. Reset the TC to factory.. and start over with all new names.. short, no spaces pure alphanumeric.
TC name and wireless name/s should conform. By default the disk share name is data which is fine.
2. Mavericks has changed over from using AFP to SMB for network filesharing.. why Apple why??
This is unhelpful to say the least. Many many people are struggling with TC and being unable to mount the network drive.
So do it manually and force it back to AFP.
In Finder use top menu, Go, Connect to Server.
Type AFP://TCname or TCIPaddress (it must be the network name of actual TC.. or its IP address)
When the computer locates the resource it will ask for a password.. it is public by default.. supply your password or public and save it in the keychain.
3. Delete the existing TM setup and start over.. See A4 here. http://pondini.org/TM/Troubleshooting.html
I cannot promise this will fix it but should reduce the problem to now and then.. rather than every time TM needs to backup.

Configure static ip address through time capsule for Filemaker Pro

I am trying to setup a static IP Address for Filemaker Pro Instant Web Publishing.
My current configuration is that I have a Netgear CG3100D modem/router set up to be a modem only. NAT Mode is Disabled (Bridge Mode). This is then connected to my Apple TimeCapsule.
What I am now trying to do is to configure my Windows 7 PC to have a static IP address so that remote devices can access my filemaker pro database.
I have downloaded (and configured?) a tool called no-ip DUC v3.04 that I thought would help solve my connection issues, but I think that I still have a problem with how to open a port number.
When i open my browser and make a connection on my network with the ip address:port number specified through Filemaker I can get a connection. However I can not get a connection remotely.
I know I haven't provided a great deal of information here, but I am happy to provide more, once I konw what information is required.
Any assistance or advice with this would be really appreciated.
Thanks

I'm not too familiar with FileMaker Pro, but if you like to give static IP addresses to anything you would have to use DHCP Reservations using Airport Utility.
Open Airport Utility, select the Time Capsule device, click Manual Setup, navigate the Internet icon, then the DHCP tab, you'll see DHCP Reservations towards the bottom.

Modem/Router to use with Time Capsule

Hi forum,
I would like to work around a DOUBLE-NAT problem that I am encountering in my business network.
Currently, my ADSL modem/router is an Orange Livebox which creates its own internal network (192.168.1.x).
My Time Capsule is connected through ethernet to this LiveBox in DHCP/NAT mode. It creates a second internal network (10.0.1.x). All the rest of the network equipment is attached wirelessly or by ethernet to the TC network. My goal is to manage the network (ports, dhcp addresses, etc.) through my Time Capsule, not through the Livebox. That is why I configured TC in DHCP/NAT mode.
The downside is that it creates a Double-Nat problem, because each packet is going through both networks (192.168.x.x and 10.0.x.x). Lately, Apple Support is telling me that this Double-Nat issue could be the cause for failing to answer iPhone calls directly from my MacBook Pro (new feature of Yosemite) when connected in my business network, where it works perfectly when connected from home in where there is no Double-Nat issue.
I contacted Orange Livebox technical support and asked wether it was possible to de-activate the router portion of the Livebox, at least the DHCP/NAT portion of the box since I would not mind to keep the built-in firewall of the box. But the answer was no. It looks like I cannot turn off the router portion of the Livebox at all, so my only solution for them is to enable the bridge mode on TC, which I still don't want.
I was told to buy a ADSL2 modem and replace my Livebox with it, so TC would effectively become the only router on the network. That looks to me like a satisfying solution (at least on paper).
Would any of you know and recommend a particular brand/model to work with Time Capsule. Ideally, what i would like this modem/router to do is :
Modem part: connect with my provider in ADSL2 and provides my credential to establish the connection
Router part:
DHCP/NAT = OFF
built-in firewall = ON
I assume it would be the best way to get the best of my Time Capsule (802.11n - 3rd Gen).
Thanks for your help or advices on the matter,
Lanceloz

I believe I followed your structure step by step. And here is what I got (see attached files). Hence my question about the TC hardware and software version that you are using.
