wifi stops working

[Kaspar Tint]

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:

Here is a way to temporary fix the problem: http://askubuntu.com/questions/442963/tl-wn821n-wifi-not-working-correctly/490992#490992

Maybe the fix in the github repo could be added into the next release?
