Wireless card makes W7 lag?
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 22.214.171.124
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?
