I've seen too many across too models over the years. I no longer fix it. We unplug the internal wifi card and install another in the PC-Card slot.
Some fight this but that's their choice. We are more than happy to charge them for the hours and in the end...
I have a T42 IBM Laptop running XP..... The wireless cuts out randomly.... Is there a program I can install that will help with this? Any suggestions would be helpful.. Keep in mind I am a computer novice so try to explain completly what you are telling me to do..LOL
