DHCP problems for wired devices on my network

Ideally, there shouldn't be any configuration needed. Access points are transparent and only work as a bridge between wireless and wired network so devices should obtain their IP info from your DHCP server not the access point by default.
If you face problems, then there might be a DHCP server in the access point, disable that.

good luck

I DON'T THINK YOU CAN RUN 2 ROUTERS ON THE SAME NETWORK UNLESS ONE IS USED AS AN ACCESS POINT.
1. Connect as local device or bridge - If connecting the second router via Ethernet cable, plug it into one of the LAN ports on the first router. If connecting the second router wirelessly, ensure the second router is set for client mode. Note that some home wireless routers do not support client mode; these must be connected by cable. Check your router documentation for details on its client mode configuration support.

2. Check / change IP address - Most home network routers use a default IP address setting. Often, these default IP addresses will not work in a two router environment. Check the second router's IP address value and reset it if necessary to work within the valid address range of the first router (and to not conflict with any other device on the network).

3. Disable DHCP - To avoid IP address conflicts between all of the devices on the home network, only one of your two routers should assign addresses via DHCP. All mainstream routers provide an option to disable DHCP as part of the router's configuration screens.

Instead of adding a second wired router to an existing network, consider adding a network switch instead. A switch accomplishes the same goal of extending the size of a network, but it does not require any IP address or DHCP configuration, greatly simplifying configuration.
Readers Respond:

First of all check the configuration of the unit if it's AUTOMATIC IP/DHCP, if all OK you can test by configuring a static IP (use an unused IP in the server's DHCP table) than check the connectivity (ping something), if that works you have a server rule/DHCP or DNS problem

if it's still not working check the cabeling and connectors for connectivity (with a good cable tester) or an other (working) computer.

Good luck!

You must ensure that you have enabled the router as a DHCP server and the client PC network connection is set up to "obtain an IP address automatically". If the computer is not obtaining a valid IP address from the DHCP server (i.e. the router) you will get the limited or no connectivity error. You can easily check to see if you have a good IP address by opening a CMD prompt window and running ipconfig.exe. Generally, the WBR-1310 will have assigned an IP address like 192.168.0.xxx. If you have an IP address like 169.254.xxx.xxx you router is not assigning your computer a valid IP address. Powering down the PC and/or the router will usually fix this, but not always. There are other, more compliated, steps that can resolve the problem if the above steps do not work.

zSB(3,3) Installing a Two Router Network Installing a router to work as the second one on a home network requires special configuration. Do the following on the second router to ensure it (and the devices attached) function properly:

1. Connect as local device or bridge - If connecting the second router via Ethernet cable, plug it into one of the LAN ports on the first router. If connecting the second router wirelessly, ensure the second router is set for client mode. Note that some home wireless routers do not support client mode; these must be connected by cable. Check your router documentation for details on its client mode configuration support.

2. Check / change IP address - Most home network routers use a default IP address setting. Often, these default IP addresses will not work in a two router environment. Check the second router's IP address value and reset it if necessary to work within the valid address range of the first router (and to not conflict with any other device on the network).

Make sure you are plugging the SMC into the WAN port on the Linksys router and not the LAN ports.  Your internet connection (which is your SMC) should always plug into your WAN port on the Linksys.  Any computers that you may need to plug in, like Desktops that are "wired" and not "wireless", should plug into the LAN ports on the Linksys.  If you are not using the WAN port on the Linksys for your SMC modem, then that would explain why you cannot get to the internet on wireless or wired computers.
Here's why you are getting the "low connectivity" message:

Computers don't understand why the Internet is connecting or not connecting...so the "low connectivity" message you keep receiving has nothing to do with your wireless signal strength.   To a computer NIC, "low connectivity" means your network adapter could not find a DHCP server and receive a valid IP address.  When this happens, your network adapter assigns an IP address to your computer in the following range...169.254.0.0, and will display the "low connectivity" message until it is able to receive a valid private IP address from the DHCP server.  You can verify this by going to START | RUN and typing "cmd" (without the quotes), then hit ENTER.  A black box will pop up....then type "ipconfig" (without the quotes) and hit ENTER.  This will show you your IP address, subnet mask, and gateway address, and you can verify that your IP address is in the 169.254.0.0 range.  A valid private IP address is typically in the 192.168.0.0 range, but could also be in the 10.0.0.0 range, or the 172.16.31.0 range.    Also, make sure you have DHCP server enabled on the Linksys router for the LAN.  This will ensure your "wired" and "wireless" computers receive a valid IP address.  
The WAN port on your Linksys router should be configured to "Obtain an IP address automatically using DHCP".

Cheers!

Are there any network devices in your device manager that have an exclamation mark next to them? Do you have your wireless router set up on DHCP?  This will give your computer an IP Address automatically.  If not, it could be a problem with your IP Address.  To check your IP Address open command prompt (Start -> Run -> type CMD and press enter) Once the command prompt opens type IPCONFIG /ALL See what it says for your IP Address... If its 169.XXX.XXX.XXX then your DHCP is not working. Check the router at that point to make sure it is turned on. If it is, try rebooting the router.

Try rebooting the router. Then make sure that all the lights on the front of the router are green. You can also call ATT and ask them to ping your router to make sure that it is connected to the internet.

There are several private address ranges that may be affecting the operations you are attempting to perform see table

IP Address Ranges Reserved for Private Use
Class Networks A 10.0.0.0 through 10.255.255.255 B 172.16.0.0 through 172.31.0.0 C 192.168.0.0 through 192.168.255.0
All addresses in this range in your network are only directly addressable to machines within your network at most by default. The router to your ISP and the internet as a whole maps these addresses onto the IP address assigned statically or dynamically by your ISP to the WAN side of your router using an address translation (NAT) service. So where you are attempting to connect to this device from may be significant. You may need to review your setup guide to see if it references router configuration requirements to support access to the Web_xpander port from devices not attached to your internal network. If you have multiple internal networks (address ranges and not devices) this could also be an issue.

Secondly -- does the Setup software for the device tell you the IP address assuming it is dynamically assigned. Otherwise how would you know what the address is. Static assignment could resolve that issue however you must understand your network to assign your own address. Given a theoretical network where the router gateway is 192.169.0.1 and the network mask is 255.255.255.0 the valid network addresses are 192.168.1.0 - 192.168.1.255. A router or other device supporting DHCP address assignment reserves another range such as 192.168.0.100 for 50 leases (ending at 192.168.0.149) for dynamic assignment to requesting network adapters. Ignoring the 0 and 255 address this leaves open to the network administrator (you in your home) the possibility of assigning static IP address in the ranges of say 192.168.0.2 - 192.168.0.99 and 192.168.0.150 - 192.168.0.254 or so. You as well as the DHCP server are required to assure that there are no duplicate IP addresses assigned on your network. So statically assigning 192.168.0.100 (which is DHCP assignable in our case) could and would most likely result in duplicate addressing and network problems.

Hi gymny,

The best connectivity in hosting application is using virtual ip network. Normally DHCP always changing IP in everytime your computer reboot or shutdown.

Hope this will be helpful to your problem.
