lowyhong: Hm. This is a concern, because I plug both my network adapter and current mouse's nano receiver directly into the motherboard, side by side. Does this happen regularly to anyone else here? Maybe I'll just get a corded mouse.
Its not an uncommon issue, the nano receiver isn't a bluetooth device. Its 'radio' signal can interrupt wifi traffic. I didn't have any luck changing my router's channel, and switching to the 5ghz range from 2.4b/g didn't dodge the problem either.
Its been a while since I updated my driver though. I get the issue in both Windows 7 and Mac OS X.
If I was to buy a replacement wireless mouse, I'd go with a bluetooth one. If I was going to use the mouse primarily to play games requiring accuracy, I'd pick up a basic corded mouse.
Other than this issue its been a great mouse. Excellent battery life, the frictionless wheel lasted about a year before getting 'gummy' and its survived a couple of trips at high velocity into the nearest wall.
