Extending wireless network Using old router?

[AMDPower]

Hi all

I am trying to extend my wireless network downstairs but I am running into difficulty. I have followed the following guide (link below) and the wireless works fine but the wireless stops after a while and requires hard reboot. I have tried with 3 different routers and same issue, so i bough routers that are the same model and still nothing.

The setup is basically,

Main wireless router upstairs is Netgear DG834 and downstairs is DG834G c5. The downstairs modem is connected with cable to the main router upstairs . To the downstairs is connected one computer to the LAP port and also provides wireless access to kitchen ands living room. But for some reason the connected computer via lan port works all the time but wireless only works intermittently. Upstairs is always working both wired/and wireless computer than connect to the router.

so what is the problem? I am kindda lost here, not even sure what to try now.

any help on this issue would be appreciated thanks.

Hi there, I think upstairs is DG 834G V2 which is wireless. I thought maybe the downstairs router problems is that i have the living room computer connected via lan to it?

I have also sera name SSID, Security, password but different channels. upstairs is 1 and downstairs is 6.

I am baffled, they are both the Same speed, but the downstairs Is ADSL 2 capable while upstairs router is not.
