Hello. I have a Dell Inspiron 1011 running XP SP3. Some time ago it had a horrible 'fake antivirus' virus that required lots of cleanup. After that work, the wireless never worked again. There is a button on the keyboard to switch it on, and it says it is on, but it does not pick up any wireless networks.
A Dell technician did a home visit for a forgotten reason and looked at the wireless, but he couldn't figure it out either, and his advice was to Google the problem. Any tips?
