I have a Netgear WG111t usb wireless adapter on an HP computer that is about 5 years old. The problem is that every couple hours the wireless connection drops and it has to be unplugged, or the computer reset in order for it to connect again. However, I tried the usb adapter on 2 of my newer computers and it worked flawlessly. Is it something with the USB ports on the HP? Any ideas would be appreciated.
