I know there are many posts like this, however none of the fixes I have found have worked.

I had the issue on 11.04, and after having no luck fixing it decided to try 12.04 however this has not fixed the problem. I'm using a Lenovo IdeaPad, the network card is a Atheros Communications AR9285.

edit add outputs:

sudo iwconfig
lo        no wireless extensions.

  • You should add the usual outputs for troubleshooting a wireless problem to the question. As is, the question is rather vague. Jul 10, 2012 at 17:28
  • What would these be? (I'm new to ubuntu/linux), The speed is just throttled to 1.5Mbits, when I should be getting 12Mbits, which I get with a cable.

  • These two should be a good start: lspci -nnk | grep -iA2, sudo iwconfig. Please add the outputs to the question, or post them to pastebin.com. Jul 11, 2012 at 23:38
  • I've added iwconfig, but lspci -nnk | grep -iA2 just returnedUsage: grep [OPTION]... PATTERN [FILE]... Try `grep --help' for more information.

  • I am sorry, it should have been lspci -nnk | grep -iA2 net. Jul 12, 2012 at 11:14

The tick box was not listed as "Pre-Released updates" but all boxes were ticked on the updates tab

  • Fix worked temporarily but now is back to slow speeds

  • Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. Aug 3, 2012 at 20:51
