I have the above adapter in my Gateway GT5628 computer. My PC (Vista) has been dropping off the internet quite regularly. I have talked with Linksys and Comcast. They have tried a bunch of stuff. Linksys had me change the ethernet port. I do have a wireless XP and another Vista on the network. The XP drops once in awhile. The 2nd Vista drops when mine is off. I am told it may be the network adapter. I am a bit of a novice and am just searching for an answer. I have changed out the cord between the Linksys and my computer. Linkysys does not think it is them since the XP is fairly reliable. Dropping for a few seconds. Any suggestions for me? It says it is working properly and that my drivers are fine. I don't know what else to do. Reading through Intel, I get the feeling this is on the motherboard. Am I looking at a real big challenge here? Help if you can. Thanks.
