Router behind router setup help

[tubesteak]

I need help setting up a router behind router so my laptop can get wireless while my tower stays wired. I'm renting a room and the house network here is not wireless, but ive got a cable coming into my room from the main router. I've tried disabling the DHCP on the wireless router I've got, but i still can't access the internet. I must be missing a step or something.
The router connected to the modem is a Linksys BEFSR81, and the one I'm trying to connect to the router is a Linksys WRT300N V1

What network ports are you plugging into?

Change the ip address of the router to 192.168.1.2 and plug into the LAN ports

I've currently got my laptop plugged into one of the 4 ethernet ports. Changed IP to 192.168.1.2 what should I do now?

What GZ meant was how do you have to cable from the first router connected to the second. In most cases you should be using one of the LAN ports and not the WAN port. Try it connected that way and leave your laptop wired. Then does it get online? If so then you should be able to setup and wireless security and disconnect the wire and use your laptop wirelessly.

i was using my laptop to try to configure it. you know what, i have 0 idea what most of these acronyms are, do you want me to just upload screencaps of the menus i'm in and you guys tell me what to put in the boxes? i'll even number the boxes if you want

do you have internet access with your laptop plugged in?

The menus have nothing to do with the way the cables are connected. The WAN port is basically the standard in bound port. On the Linksys router you have it would be the one single blue port. The LAN ports are the networking ports that you connect the PC to and they'd be the 4 yellow ones.

What you should have is the cable you have from the main router connected to one of the 4 lan ports. Disable DHCP as you have, change the ip address of the wireless router to 192.168.1.2(that might not even be needed) and then see where you stand.

If you still have your laptop connected wired and still don't get online then you might need to try restarting all the connections, or you might have something else setup wrong.
