I'm new to Ubuntu and i just brows the web and edit photo's. I'm running a Ubuntu server for 1 year now and i love it. But now when I'm just doing something the WiFi icon look like it searching and then it connects but without a notification. but instead i get a disconnected error. here is a screen shot:

enter image description here Here is some of the output of lspci -v:

+1 for using Gimp ;-) . What hardware is your ethernet device using, with what driver? You can use lspci -v or lshw -C network –  Wilf Jan 26 at 17:20
    
pastebin.com/Lw8Qpb2L And i'm a Gimp lover :P but i need to change the splash :D –  user3104326 Jan 26 at 17:34
    
Errr... You have TWO network cards shown, do you know which one has the problem, or whether the other one works? I think the AR8152 has the right driver... But it varys :-s –  Wilf Jan 26 at 17:41
    
uhmm well it's just a laptop so i don't know but i think it has only 1 network car and i think i use AR9285 for wifi and the other for lan so i think it's the first one –  user3104326 Jan 26 at 17:44
    
Which version of Ubuntu are you using? And does it work with other wired networks? –  Wilf Jan 26 at 17:55

I did fix it! i did go to the connection icon and then to settings and deleted the ethernet connection! so now it doesn't give me the error!

Strange, seems like a bug that should be filed –  virtualxtc Jan 27 at 20:12
    
Well done! :D Bit weird though... –  Wilf Jan 27 at 21:08
    
Yes i know should i write a mail to them? –  user3104326 Jan 27 at 22:50

Ensure your kernel is up to date and try:

sudo -s
echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf

@virtualxtc What does this have to do with ethernet? –  chili555 Jan 26 at 22:31
    
@chili555 the user claims to be using wifi when this happens. –  virtualxtc Jan 26 at 22:51
    
@virtualxtc Indeed i'm using WIfi when this happens. Btw my laptop is dual-booted with windows so if you want to I can give you the good Network driver ;) –  user3104326 Jan 27 at 6:51
