Internet Timeouts with TP-Link TL-WN821N v2 wireless usb stick
- by user1622959
A short time after accessing the internet, the browser/download times out. Before the timeout, the internet works OK briefly; afterwards, the wireless is still connected with a strong signal, but every internet access results in a timeout. When I leave the PC for a while, the internet is back just to timeout again as soon as I start using it. The same happens when I reconnect to the router. Also, when I surf the internet, it takes a couple of minutes until the timeout, but when I download something, it times out in a matter of seconds. The wireless adapter works just fine in Windows and internet via ethernet cable works just fine in Ubuntu.
Does anyone have the same problem or knows a solution.
I use Ubuntu 12.10 x64. The problem occurs since I installed ubuntu (which was a few days ago).
Here some stuff that might be usefull:
