Issue with running 2 WRT54GS wireless routers

Specs: Windows 7 x64
Ok, so before I get started, I should list my setup.

I have cable internet. I have a Linksys CM100 modem. This feeds to a Linksys WRT54GS router. That router then feeds to another WRT54GS that is configured as a switch/access point. This feeds into my computer, my media server computer, and my xbox. The first router also feeds to a Netgear FS605 switch, which in turn feeds two computers in the room next to me, as well as another xbox. Finally, my roommates computer and another xbox are hooked up to the first router. This setup has worked perfectly for about a month.

Last night, the internet stopped working. We have recently moved, and had a number of difficulties with the ISP in the old apartment, so we blamed them and did other things for awhile. Eventually, I decided to reset everything and see what happens. That's when I noticed all the lights on the modem were on. I plugged in directly to the modem and got online without a problem. So I started resetting the routers to see if that was the issue. No luck. So I started trying everything one by one.

The first WRT54GS seemed to work fine, but we couldn't get online. After trying a few things, including the factory reset button, I noticed that the router was not receiving an IP, subnet, or DNS from the modem. After resetting both the modem and router, nothing changed. This had happened before in the old apartment with the modem supplied by the ISP. We replaced the ISP modem with a new one that we bought ourselves, and that fixed the issue. Now, the same thing is happening with the modem that we bought.

The second WRT54GS won't seem to work at all. When I plug into it and run ipconfig, it shows media disconnected. When I attempt to ping 192.168.1.1, it times out. It seems to just be a black hole, the network knows something is present, but nothing seems to happen. The 1, 2, 3, 4, and Internet lights stay on at all times (even with nothing plugged in) and the power light blinks rapidly. Some googling turned up that this might be corrupt firmware. This had happened before and I was able to fix it. However, the first time it happened, I was still able to get a ping response and a response in ipconfig (not just media disconnected). I fear the router might be a lost cause.

The switch seems to work fine. I can connect through it, ad I'm connected through it right now. Obviously, only one person can connect through it at a time without a router, so this doesn't help the immediate situation.

I'm running Windows 7 x64 and an nVida nForce NIC, if that's any help.

Why don't you simply use the working WRT54GS, to connect to the internet?

Like this:
PCs <--> Netgear Swich <--> WRT54GS <--> Modem <--> Internet

Neither of the routers work, that's the problem. One doesn't function at all. The other one, the one that seems to work, won't get info from the from the modem. The router doesn't see an IP, subnet, or DNS from the modem, but when I plug straight into the modem from my PC, I can get online just fine, IP, subnet, DNS and all.

Have to configured the router with the correct provider informations, to authenticate to your ISP?

What IP address did yuo get, when a PC is connected directly to the modem?
Maybe you can post an:
ipconfig /all

Ok and when connecting the router to the modem, means routers WAN port to Modems LAN port, then connecting PC to the Routers LAN port, did the PC get an IP address like 192.168.1.x ?

Furthermore can you access the web interface of the router and check the status page?

Yeah, I get an IP from the router just fine. The issue shows up on the router's status page. According to the status page, the IP, DNS, and subnet are all 0.0.0.0.

I would expect the second router's dhcp server to be turned off so if you expected to get a ip address when connected to it that would be incorrect. It was standalone when you tested it. You would have defaulted to a 169.254.x.x ip and not be able to connect to the router.

When you hookup the first router to the modem does the wan light lightup? Is the routers wan interface set to dhcp client?

The WAN light is on. It's set to DHCP client.

clone the workstations mac address to the router. Should be a button to this effect on the wan page of the router.
