I do not know whether I should put this question in the CPU forum or in wireless networking, as it kinda combines the two. Anyway, I have a wireless D-Link DWL-G550 adapter. When I connect to my wireless network, the CPU load goes to 100%, which of course, slows down the computer tremendously. On a few occasions it did not happen, and connection to the network did not cause this problem. But as a general rule, it does. I can't figure out what causes this problem. It seems quite unique as Google did not return any results on my query about this problem.
