Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

So I am using Ubuntu 13.10 and I have this USB wifi device (TP-Link TL-WN821N V4) in my computer.

Now when I use internet via terminal, everything is just fine, I can upload and download the whole internet if I want to. But once I open up a browser(does not matter if firefox or chromium), I can navigate to like 4 pages and then my connection stops. I can still see that I am connected but I cannot use the internet anymore.

Also when I disconnect from the currently connected network, I will not be able to reconnect there anymore.

This problem for now is only fixed with a restart. So for every 4 pages I visit, restart.

I have also gotten some logs and info:

Maybe worth to mention that I have also tried to install the windows drivers with windows drivers installer program that Linux has, but that resulted with horrible effects. I had to reinstall Ubuntu after that.

So yes, what could be a problem here? Am I using the wrong open-source driver here? And do you guys need anymore info. I hope I took the syslog info from the right spots, from the time table it does seem like the time the network anomaly occurred.

Is there any more info needed? I would gladly supply any. –  Veske Apr 7 at 15:00

1 Answer 1

Found a reference to this bug in which comments suggests blacklisting the driver like this:

echo "blacklist ar9170usb" | sudo tee /etc/modprobe.d/blacklist-ar9170.conf

After reboot, it should work better. If not, remove the /etc/modprobe.d/blacklist-ar9170.conf file.

All right! I will give it a shot. –  Veske Apr 7 at 21:43
    
Okay, so I tried it and I was able to browse for a little bit longer this time and also the pages loaded faster in my opinion, but the connection stopped after some time again. I removed the blacklist file now. How should I proceed now? –  Veske Apr 7 at 22:00
    
Also, I noticed now that when this wifi problem happens and I go to Wifi options, then I can untick the Enable Wifi button and then re-enable it. This will get me the connection back without a restart now. But it is still pretty ridiculous ofcourse to do this after loading 4 pages every time. –  Veske Apr 7 at 22:03
