I installed a new wireless N card in my W7 desktop.
After a while, the connection starts to weaken and becomes unusable, though it stays connected with "internet access". Eventually I have to manually disconnect and reconnect.
The signal is down to 2 bars when connected but when I disconnect it jumps to 4 bars.
Wireless card driver: Ralink 3.0.2.0

At the same time, the PC starts lagging. The mouse and keyboard become jittery and unresponsive. Some programs just freeze. When it disconnect/reconnect everything is normal again. I can also wait it out. The CPU and the Ram don't even change or react to the lag.

I think the lagging and the wireless problem are unrelated, but they occur together. There is something wrong with the wireless driver, right?
 
Update the card driver with the latest one from the manufacturer. If that doesn't work try a generic microsoft driver to see if that helps.

May also want to ensure your router isn't killing the signal by testing the card on another PC.
 
Updated to 3.0.11.0
Nope. Still the same.
Nothing is wrong with my router, tested with a laptop. I don't have another Desktop to test it on.
How do I get the generic Microsoft driver?
