Ever since I lent my laptop to my sister, the wireless network doesn't work properly. It is telling me that I have a strong signal, however the little computer is greyed out in the taskbar so I can't connect to the Internet. When I go to choose the wireless network, it says that it can't come together wireless connection. I don't know what she has done. Any ideas?

Best way to fix problems.. SYSTEM RESTORE!!

If it was working before but stopped working now, just do a system restore

Click START>>PROGRAMS>>ACCESSORIES>>SYSTEM TOOLS>>SYSTEM RESTORE

Choose a date to when the system was working. and restore.

Done
