Hi!
So I have TL-WN821N V4 USB wifi device. It connects to WIFI, I am able
to download and upload stuff via terminal for as long as I want to. The
problem occurs when I open up a browser (does not matter which one, have
tried all).
I open the browser and navigate to different pages. After like 5 minutes
of browsing, I am not able to browse anymore. Wifi is still connected
but no info is going though. I can also do a ping google.com in Terminal
and it will yield no result.
This bug occurs on my system that is running a fresh 14.04 Ubuntu 64
bit. It also occurred hwne I ran Ubuntu 13.10, and that is also the time
I ran the wireless script shown below.
Here is some info that I got with a script that is supposed to pur out a
lot of info about my wifi:
