This may classify as noob or windows but anyway... We had a hard drive crash. Had to buy a new HD and reinstall XP SP2. Since then both Firefox and IE will drop connections. Usually get a can't find server screen. Windows says the wired network is still connected with no interruptions and all the lights on the router say everything is ok. We switched ISPs (for unrelated reasons) and still have the same problem. I have searched M$ and ASUS (motherboard, don't have the model number here at work) for networking drivers, updated everything I can and googled the problem with several different wordings and haven't gotten anywhere. Once I was in the midst of a download, everything quit, I left for a few minutes to deal with children, came back and the connection was up and running again. My wife has a separate login account on the computer and experiences the same thing. Any suggestions would be appreciated, and if it's something really stupid, I will accept my lashings.
