Is the date and time correct?
Is there any Norton, McAfee, Kapersky or any of those security suites that block the internet when the date/time is wrong or they have expired?
I bought a Sony Vaio laptop (VPCSA31FX) a few months back. It has been working great until recently.
Lately I can not seem to connect to any wireless connections. I cant even connect to my router at home even though my roommates are having no issues with their computers.
All drivers are up to date and restarting the router and computer seem to do nothing.
And the windows diagnostic says that a problem with wireless adapter or access point was detected.
