I purchased a TP-Link Dual Band WDN4800 adapter in August 2013. Since then it has been working fine with fantastic line-speed connectivity - up until around 8.30PM GMT yesterday.

I am completely annoyed by this. I have tried everything to get onto the Internet, but to no avail. The adapter detects the networks, but then upon entering the password, Windows says 'Unable to connect - limited connectivity'. This is despite the fact that I was using the Internet minutes before!

I have:

Uninstalled original drivers - reinstalled original drivers - NOTHING

Uninstalled original drivers - downloaded newer ones from TP-LINK - NOTHING

Uninstalled newer driver - download Atheros drivers - STILL NOTHING

Took the card out, moved it to a new slot - STILL NOTHING

Tried to connect to the 2.4Ghz network I have - NOTHING

Changed the channel of the router - NOTHING

Reset the router - NOTHING

Restored default BIOS settings - NOTHING

Used ipconfig/ renew - NOTHING

Used ipconfig/ release - NOTHING

Used netsh int ip reset - NOTHING

I just don't know what else to do now. I need help please.
