Random Disconnects and Signal Loss(Wireless)

For the last 2 days I have been getting random disconnects while playing WoW or just looking around on the internet. I connect to a wireless router(Speedstream from Bell Canada) with a Linksys 802.11g wireless network card. Up until I started getting problems it worked fine, from May until now. I have checked for Spyware using both Ad-aware and Spybot and came up with nothing and have run AVG anti-virus as well.
So far I have switched channels twice, from 11 to 10 then 10 to 7 and have gotten minimal results.

 

first of all its good to confirm with the ISP if there is any problem with their network.

 

I figured it out. My roommate had stuff piled ontop of the router blocking the wireless signal.
