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? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1310338 Title: wifi stops working Status in “network-manager” package in Ubuntu: New Bug description: 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: ########## wireless info START ########## ##### release ##### Distributor ID: Ubuntu Description: Ubuntu 13.10 Release: 13.10 Codename: saucy ##### kernel ##### Linux kaspar-All-Series 3.11.0-19-generic #33-Ubuntu SMP Tue Mar 11 18:48:34 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux ##### lspci ##### 03:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.
