Connected to wifi, shows no problems on the signals, unstable access

I've been working on this for three days already, I am using win 7 64bits with a TP-link router.

I've just moved in to a new house, with a router set up by my landlord, for the first day, I couldn't connected to the wifi, but somehow I worked that out, and could now connected to the internet (Occasionally, still couldn't get connected sometimes). Anyway, since there's no problem connecting to the wireless network, I realize it is very very unstable, it's running really slow, and might lost access to internet even when the signals show everything's fine. I tried different methods, ipconfig /release and renew, uninstalling my driver, all kinds of stuff, but the problem still exist.

What can I do?

Have you tried changing the channel that the wireless is using? The type of security and encryption being used can also make a difference.

Xirrus wifi inspector can help you find a clear channel in your area, if you are confused by what it says then just post a screen shot of the read out here. :)
