Cannot set reserved DHCP addresses on WRT54GS ?
Is it correct that users cannot assign reserved DHCP addresses to hosts on their LAN with the WRT54GS ?
Yes. Correct. It does not support this. Not with standard firmware.

OS X 10.6.7 not getting reserved DHCP address from router.
I have a MacBook Pro running OS X 10.6.7
My router is NetGear WGT624v3. I have the router setup to assign out reserved DHCP address for my Macs.
I am not getting the reserved address, but rather "any" address in the pool.
Other types of devices are getting the reserved address. For example, old windows computers, and my Android phone. Only the Mac computers seem to be getting the incorrect addresses.
Any ideas please?
DuaneAs long as it shows up in the Windows Boot Camp control panel I'd say fine, happened to a lot of people - I have not had Windows 7 show in Mac Startup Disk control panel for years in my Mac Pro.

Cannot get a DHCP address from my ISP
I just got a WRT54G router, I managed to configured it all. I can ping any computers on the network. What I cannot do is get my DHCP address from my isp, meaning that I can't connect to internet.
I am 100% sure that my ISP address was given by a DHCP server since that's how it was configured on my old router before it got smashed into pieces.
I have the latest firmware upgrade for the router (version 6) and it is correctly plugged in my modem.
What is strange is that couple of hours ago, I managed to get an address for about 15 minutes, then it dropped and I have not been able to pick a new one anymore, no matter what I do.
Anyone can help me?Achnod wrote:
Alright, but how do I do that?
Disconnect the power cord.
Or if its a telephony modem, hold the reset button until it reboots. -
i have reset the ACS Appliance, after that i cannot set the IP address. it return error when i try to set the IP address. any solution?
Hi There,
In order to resolve this issue, make sure that Cisco Secure ACS Solution Engine (ACS SE) is connected to a Ethernet connection that works before you set or change the IP address of your ACS SE.
Complete these steps in order to reconfigure the IP:
1. Log in to the ACS SE. Refer to the Logging In to the Solution Engine From a Serial Console section of Administering Cisco Secure ACS Solution Engine for more information.
http://www.cisco.com/en/US/customer/products/sw/secursw/ps5338/products_installation_guide_chapter09186a008070c61b.html#wp1042941
2. Type set ip, and then press Enter.
3. At the Use Static IP Address [Y]: prompt, type Y for yes or N for No, and then press Enter.
4. If you answered No to the use of a static IP address, the system displays a confirmation of DHCP and the message IP Address is reconfigured. Continue the procedure with step 5.
If you responded Yes in the previous step to use a static IP address:
1. In order to specify the ACS SE IP address, at the IP Address [xx.xx.xx.xx]: prompt, type the IP address, and then press Enter.
2. At the Subnet Mask [xx.xx.xx.xx]: prompt, type the subnet mask, and then press Enter.
3. At the Default Gateway [xx.xx.xx.xx]: prompt, type the default gateway, and then press Enter.
4. At the DNS Servers [xx.xx.xx.xx]: prompt, type the address of any DNS servers you intend to use (separate each by a single space), and then press Enter.
Result: The system displays the new configuration information and the message:
IP Address is reconfigured.
5. Review the information presented and, at the Confirm the changes? [Y]: prompt, press Enter.
Result: The ACS SE restarts. The system displays the message:
New ip address is set.
Refer to the Reconfiguring the Solution Engine IP Address section of Administering Cisco Secure ACS Solution Engine for more information.

Lion Server not handing out DHCP addresses to Snow Leopard client
I have been pulling my hair out over this.
Here is the layout
Lion Server running on the newest Mac Mini and doing mail, DNS, DHCP, Software update and has a valid, not self assigned, certificate
3 clients running Lion Desktop (2 iMACs and a MBP pro (all no more that a year old and all woth the current updates)
1 client running Snow Leopard Desktop (last years 13 inch MBA)
The 3 Lion clients can get dhcp fro mthe Lion server without any issue
The SL client cannot get a DHCP address from the Lion server
A tcpdump shows the DHCP request coming from the MAC address of the SL client but no response from the Lion Server and nothing showing a deny in the logs for the DHCP server or any other system/kernel logs. The Lion clients all show the request and reply for them. All 4 clients currently have a static assignment in DHCP but even if I remove them all and do auto-assign for everything or even each one individually, the SL client will not get an address both on the Wifi and Ethernet (I have the USB ethernet adapter).
I also have an Aiport Extreme and if I use that for the DHCP server then all clients get the addresses. I know the DHCP server in the extreme cannot be shut down but if you give the extreme a static address then assign dhcp on the extreme to only give out one address and that is the same one that is statically assigned then it "thinks" it is out of addresses and no longer tries to assign addresses
At first I thought there was a conflict between the extreme and the Lion server but as I mentioned above, tcpdump clearly shows the requests going right to the Lion server
I'm usually pretty good at this kind of thing but this one has me stumped. I'm thinking bug, anyone else run into this yet?Ryan jones,

MyComputerGuyJo:
I just wanted to add what Apple Support walked me through. Worked perfectly. Similar to some of the posts here. This assumes you have finished the setup of the Airport using DHCP to obtain the IP automatically from Comcast and it says the IP is invalid.
Power off\on Sequence
1, Power off Comcast Modem. Remove Battery back up, if it has one. Disconnect the coax cable.
2. Power off Airport Extreme
3. Let both sit for 3 minutes.
4. Reconnect coax cable to Comcast modem and replace battery and power up.
5. Wait a minute or two to make sure the Comcast modem is completely up and then Power on the Airport Extreme.

Freyfisher: I had the same problem whenn I switched to the Airport Extreme yesterday. Here is what I did:
1: uplugged modem for 30 sec. and detached all ethernet cables. Plugged back in and reattached airport extreme cable after all lights were solid on the modem. Then, I went into Airport Utility and selected, "Base Station"> "restore default settings". Then" Base Station"> Restart. Then go through setup assistant again. If no luck, try setting IPv4 to 10.0.1.2, subnet to 255.255.255.0, router to 10.0.1.1. IPv6 set to OFF if having trouble. DNS adresses: 75.75.75.75, 75.75.76.76, search domain hsd1.ST.comcast.net where "ST" is your two-letter State abbrev. Hope this helps someone.... -
Cannot get On 100 to get DHCP address
I have used two different network cables, 3 different network locations and factory reset device twice but cannot get it to get a DHCP address.
It boots and status 1 goes solid amber and status 2 blinks amber
Anyone have an issue like this before?thanks Robert,
The customer has both voice and data scopes defined on a single dhcp server (C2811 Router). I've managed to get the static ip configured on the ON100 agent. This was accomplished by moving the ON100 lan connection to an uplink port on the switch. Odly enough, I was able to see the ip address assignment in the dhcp pool, but the configuration on the ON100 still had the static configuration from the previous network it was moved from. I used the new dhcp assignment to log into the device and make the change. I am now having the following two problems:
1.) After moving the ON100 back to a switchport (so the pc and monitor would be in the same network surface), the ON100 is still pulling a second ip address from the voice scope, (even though the static ip is still assigned to the mac address). When I clear the entry in in dhcp cache, it reappears, leaving me with a voice and date ip for the same mac.
2.) When attempting to activate the ON100, I get the following error, could this be related to moving the unit from the lab to the customer site?

Set up MAC Address Filtering on WRT54G - now nothing connects
I set up MAC address filtering on the wireless router. Added 5 MAC addresses to the PERMITTED list, by selecting them from the available devices. Saved the changes. Now, none of the machines can connect to the access point. That includes the PC I use to log in and administer the access point. I connected the network cable directly to my PC to manage the router/access point. Still not able to connect. What happened? How do I get back in and turn that nonsense off. I know MAC Filtering is questionable wrt effectiveness, but I decide to try it.
Solved!
Go to Solution.Reset the router back to defaults. Reconfigure it from scratch.

New Time Capsule: Assign DHCP address and backup to USB disk?
Hi all,
I am setting up a new Time Capsule and have two questions:
- I am successfully backing up my MacBook Pro to the internal TC disk. I like loooong backup histories, so I would like to backup my iMac to a separate Time Machine disk attached to the TC via USB. I have googled and not found anyone saying it can be done. I have attached a USB disk and tried to configure TimeMachine to see it, but it is invisible. Is this even possible?
- I want to assign a specific IP address to a Linux server (Ubuntu Jaunty) on the internal network of the Time Capsule. I can get a "random" DHCP address assigned, but I cannot get a specific one assigned. I have tried to create DHCP Reservations for the Linux box using both its MAC address as well as the DHCP client ID (preferred). No matter what, I still get the random DHCP address. On the linux box, I have made sure to set the Client ID as well as removing the old leases file. Any hints?
Thanks in advance for any help on either front!...so I would like to backup my iMac to a separate Time Machine disk attached to the TC via USB.
That is not possible with Time Machine.
Time Machine will backup any files residing on your Mac or residing on any disk connected via USB or FireWire directly to your Mac.
Time Machine will NOT backup files residing on a network drive like the USB drive connected to a Time Capsule.
I want to assign a specific IP address to a Linux server (Ubuntu Jaunty) on the internal network of the Time Capsule.
The default settings of the Time Capsule use the addresses 10.0.1.2 to 10.0.1.200 for DHCP clients. If you want this server to have a fixed IP address, simply configure the server to have a manual IP address in the range 10.0.1.201 to 10.0.1.254. -
Multiple SSIDs with WDS, custom DHCP addresses, & Web interface
I just bought an Aiport Extreme Base station along with an Aiport Express. So far, everything is great, but I had a few of things I would like configure a certain way, and I am having a little problem.
Just to let you know, I am using the base station as the main router/firewall (with my cable modem). I am using the express basically as a wireless bridge (via WDS).
The way Apple takes care of things with WDS, is by assiging the same SSID to both the base station and express for seamless roaming. However, I would like them both to have their own SSID. I cannot seem to get this working, and I know that some other vendors allow this (Buffalo, Linksys).
The other issue is regarding DHCP on the LAN side. I want to for example hand out IP addresses 192.168.2.50-60 to my internal clients, and I want the base station to have an address of 192.168.2.1 and the express to have 192.168.2.5. It seems this also I am having problems with. It seems like the base station is very rigid on what options I have in this regard.
Lastly, I wondered if there is any other way to administer these guys (like a web browser). Sometimes I need to remotely make changes to the router, and don’t really want to install another app just for this purpose (especially at work, or some other remote location).
Thanks

I don't know why you'd want that but if you are
extending the range of your wireless network with WDS
it isn't possible with Airports.

You can set the DHCP range and then assign static
IP's to anything that conforms to that network as
long as it won't conflict with something
automatically assigned by DHCP. As a router NAT must
be enabled so if you want a unique range of numbers
only DHCP is used which won't work in your case.
In other words set the range at 192.168.1.1 and that
is the address of the base station. That can be used
for the statically IP'd device's router and DNS
entries as well like this:
Device 1 IP 192.168.1.101
Device 1 subnet 255.255.255.0
Device 1 router 192.168.1.1
Device 1 DNS 192.168.1.1

Device 2 router 192.168.1.1

Not that I'm aware of. Airport Admin Utility is all
there is. I have seen a java utility but it wasn't
very friendly.
Thanks for the answers. Despite these minor limitations, so far the Apple hardware is some of the best 802.11 stuff I have used (except for maybe a Cisco 1200). -
I am in the process of trying to create a guest network using my airport (2nd generation). I am trying to connect my new wireless Vizio to my network...
I have decifered that I can no longer use the same IP address for all devices on my network in order to accommodate my TV. To create a guest network I believe I need to begin providing numbers to each device. In trying to create a DHCP range I get error messages regarding beginning and ending DHCP address numbers. How do I choose appropriate beginning and ending numbers? Both are provided automatically but create error messages.I am not sure if Tesserax is online this evening so will answer this and ask for his input as well.
AirPort Utility has detected that you have another device acting as a router on your network. You may call this device your "modem", but it is likely a gateway....combination modem and router in one box.
If you could provide the make and model number of your "modem", we can provide more details and answers.
You only want one device acting as a router on a network and your gateway is already handling those services. Any other routers....(your AirPort Extreme is a router as well)...need to be configured in Bridge Mode to work correctly on the network.
If you do not configure the AirPort Exteme in Bridge Mode, you will have two devices both trying to act as routers on your network. This will cause IP address conflicts and other problems that will not allow the network to function correctly.
I suggest that you configure the AirPort Extreme as AirPort Utility recommends....Bridge Mode.
Now we run into somewhat of a Catch 22 situation....
Bridge Mode is the correct way to configure the AirPort Extreme to work with your gateway device. But, the Guest Network cannot be enabled in this type of setting.
The AirPort Extreme needs to connect to a simple modem...not a gateway device....if you want to have the option to enable the Guest Network feature.
It is possible that your gateway might be able to be configured as a simple bridge modem. That is a question for the manufacturer of the modem/router or gateway device. -
Reserve IP address by device?
I have a variety of Apple devices on my network, using an Airport Extreme router. (Devices include a Mac Mini, MacBook Pro, iPhones, etc.)
My Mac Mini (Snow Leopard 10.6.8) acts as an HTPC, and I would like it to always have the same 10.0.1.X address. Can someone tell me how to set it so the Mac Mini always uses 10.0.1.2, for example? My devices sometimes change addresses, if I restart the router or a device.
I tried going to System Preferences->Network->Wi-Fi->Advanced->TCP/IP-> and from here I chose "Using DHCP with Manual Address" from the drop-down menu, and I entered 10.0.1.2 as the address and applied the change ... but I wasn't able to access the HTPC from Google Chrome using the 10.0.1.2 address as I normally can.
(I set it back to "Using DHCP" and renewed the lease, and I was able to use Chrome to access my HTPC at the address it generated -- 10.0.1.13.)I tried going to System Preferences->Network->Wi-Fi->Advanced->TCP/IP-> and from here I chose "Using DHCP with Manual Address" from the drop-down menu, and I entered 10.0.1.2 as the address and applied the change ... but I wasn't able to access the HTPC from Google Chrome using the 10.0.1.2 address as I normally can.
Chances are, the 10.0.1.2 address has already been assigned to another device on your network, so it would not be available in that case.
What happens if you set the address for the Mac Mini as 10.0.1.13 in System Preferences? Or better yet, assign an IP address that would be higher than addresses than other devices on your network normally receive.....to eliminate possible conflicts. Try something like 10.0.1.25 or 10.0.1.50 for example.
Most wireless routers....including Apple....will also allow you to reserve a given IP address for a specific product. If you have an Apple router that is in charge of DHCP address assignments for your network, another option would be to have the Apple router assign IP addresses. You have to know the MAC Address of the device if you do it this way, which is a unique ID number for a device. -

No Hyperv Virtuals get DHCP address - but Physical Host Can

Machine connected directly into local network that has a DC running DHCP.
None of the VM's can get a DHCP Address from the server. Even if i set static addresses still they cannot route anywhere, cannot even ping the HyperV server they are sat on but other local machines can!!!!
The physical host cant ping the
The physical HyperV server has no problem getting a DHCP address or any routing issues, nor do any of the other clients on the local network, including another HyperV server running server VM's
What ive tried so far
Deleted Virtual Switch and removed the NIC from the virtual hosts in HyperV Manager- then re-adding new one.
Put in a different network card
Removed Physical host from Domain, renamed machine to different name and re-joined
Used different IP addresses for the Physical host
Reloaded the HyperV server from scratch and created new VM.
Ive had HyperV previously running on this machine without problem, so now i cant see why i cant get it running again.
Anybody have any suggestions on what i can try next, im all out of ideas.Hi Fulgent,
I am assuming that , the hyper-v server have two NICs , one for host and the other one was configured as an external switch for VMs .
If the VMs can not access the dhcp and local network , please try to delete the external switch then uninstall the Physical NIC in device manager and click " scan for hardware changes " to reload it.
Try to create external virtual switch for VMs again .
Any further information please feel free to let us know .
