Hi, I just moved places and got a dsl.

In my previous place I had cable, and whenever I would plug in my router, the system detected it and from my browser asked me to login.
Everything worked fine.

Now, after I install my router, I no longer have an internet connection.
I can ping my router, yet I cannot ping Wikipedia.
I tried the whole thing with restarting both devices, turing off and on.

I can access my router through when installed.
I can access my modem through when router not installed.
Though I cannot access my modem when router is installed, even if I change the ip of the router to

When I tried ipconfig /renew, I get this error message:

An error occured while renewing interface Local Aera Connection : unable to contact your DHCP server.

I've attached some screenshots of my router config, modem config, and IP Configuration.
I have a Linksys WRT54GS router, and a Microcom AD 2706 modem from Microcom.

Thanks for your help

I couldn't find a user manual in English for your modem, but you have a modem that is really a modem/router. It is also running at the same base address as your other router. I suggest configuring the Linksys base address as, and I think you'll have better luck. One issue with this connection is port forwarding for server applications will be very difficult to impossible.

An alternate method is to connect the Linksys as a wireless switch using the following procedure.

Connecting two SOHO broadband routers together.

Configure the IP address of the secondary router to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses through, I'd assign the secondary router as it's IP address.

Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!

This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).
