TP-Link TL-WDN4800 suddenly stopped working after a year of being fine ?

I regularly move my desktop from uni to my other house, and have never had any issue connecting to my BT-Homehub natively with my TP-Link TL-WDN4800, wheras at uni I use ethernet. However this time it appears to be being extremely stubborn (or OSX is, somehow)

When I click my wifi in the top bar of moutnain lion 10.8 all I ever get is "could not join "BTHub3-xxxx". A connection timeout occured."

I took a screen cap of my system report on my wifi the day I set it up working too, the only difference seems to be the status, which went from showing my hub and another local connection to now just showing nothing under the status, even though all the same connections are in range (I can tell from the wireless wizard picking up the name of my Hub in the top menu), and I even have the chocie to click to my hub it is picking up, but just end up straight at "could not join "BTHub3-xxxx". A connection timeout occured."

Every time! Any ideas?

To be exact its TP-Link TL-WDN4800 Wireless-N450 Dual Band PCIe Adapter (noticed it's recommended in one of the standard builds, and is "#1 in Computers & Accessories > Components > Network Interface Cards" on amazon!)

The first attatchment is of the original status, the second the staus now.

I'm having the exact same issue.

Were you able to find a solution?


Thanks.

Those resolutions don't help. But thanks anyway!
