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

You should add the usual outputs for troubleshooting a wireless problem to the question. As is, the question is rather vague. – mikewhatever Jul 10 '12 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. – Luke Jul 11 '12 at 22:13
These two should be a good start: lspci -nnk | grep -iA2, sudo iwconfig. Please add the outputs to the question, or post them to – mikewhatever Jul 11 '12 at 23:38
I've added iwconfig, but lspci -nnk | grep -iA2 just returnedUsage: grep [OPTION]... PATTERN [FILE]... Try `grep --help' for more information. – Luke Jul 12 '12 at 8:21
I am sorry, it should have been lspci -nnk | grep -iA2 net. – mikewhatever Jul 12 '12 at 11:14

I found this to work!

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 – Luke Jul 24 '12 at 21:18
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. – Eliah Kagan Aug 3 '12 at 20:51
