The Norton internet security has expired. I can't explain why Symantec shuts the internet off when that happens.
Suddenly, for some reason, my two Lenovo laptops last week (one is Windows XP and one is Windows 7) couldn't find any wireless networks. When I click on "View Wireless Networks" all that comes up is the Iban computer to computer network.
I know the wireless network router is working as I can connect to it with my non 3G iPad. I also took both computers to work and couldn't connect to an open wireless router there.
I am puzzled as to how to even begin troubleshooting.
