I have a Gateway laptop with Windows XP. After starting my computer, the internet connection works for about 5 minutes, then gives me a Network Timeout message. The connection is still "excellent", and I have tried my computer on several different wireless connections and still have the same problem. If I restart the computer, it works again for a few minutes.
I have run a virus scan with clean results. I haven't recently installed any new programs. I have tried connecting with the firewall turned off. I am wondering if it is related to my wireless card (Linksys). I have tried installing new drivers and nothing has changed. What could be causing this issue?
