Here is my situation:
I rent an apartment on the first floor of a house. My landlord has his offices upstairs. There, he has a cable modem and a Linksys WRT54GS. That router is then connected into a wall socket using an ethernet cable (I assume the other end is in one of the LAN ports of the WRT54GS).
Then, on my floor, I connect my wall socket to my router, a Linksys BEFW11S4 (Version 3). The only way my router works consistently is to connect the wall socket to the Uplink port of my BEFW11S4. However, it's only wired connections that work; I have never been able to get wireless working. Because of client confidentiality, my landlord does not want me to use his wireless connection, so I need some way to get mine working.
Several articles explain how to set up my router as an access point. I have tried the method described (switching the Device IP address, disabling DHCP, changing SSID and channel), but again, things only work using the Uplink port. I can never seem to make a direct LAN-LAN connection (the lights on my router never come on). And I can never get wireless working.
Any thoughts on where the problem might be? Or maybe a way that my landlord could give me wireless internet access using his WRT54GS that would not give me access to computers on his network? I really appreciate any help!
