My os has always been 2k, I had a problem with my motherboard...corrosion of all things...but redid the pc with 2 100 gig hd's instead of 2 60's...the mobo has built in ide raid, running raid0, so the harddrives are shown as 1 200 gig, with 4 50 gig partitions...I was thinking...could the problem be that the built in nic on the receiver is 10megs and the wireless is 11, should I lower the wireless connection speed to 5.5 on the wifi nic?
