Another Wusb54g Problem

Hey how are yall doin.I been having this crazy problem.I have a wrt54g linksys router setup in my basement.Then where im at now i have a usb adapter Wusb54 v4. I know ive heard things about vista and this adapter so im not sure if thats it or what.Anyway but the problem is my connection with the adapter is constantly dropping.It will drop then my family network will disappear from the list.Then when it shows up again i cant connect.So i looked at my network connections and viewed full map and it said my adapter is not connected.Even though it is.I dont know how the adapter cant be connected. I dont know if it something with driver or not i have know clue.I already had to go back to the oldest driver because the newest drive doesnt work p2p software.But ive rollbacked to the newest and i still get the same problem.Also when i loose my connection on this pc i cant connect to xbxo live.Im thinking that the network is constantly dropping every lil while.But sometimes i can stay connected for a whole day then out of nowhere it happens.

If you have any questions ask then and please answer this for me im going crazy.

Thank You
