Xubuntu Wifi issues with ath9k

Hello All:

I recently installed Xubuntu 14.04 on my system and am having a strange problem with the atheros wireless card.

The basic issue is that the system detects the card and even detects the usual list of available, in-range access points. However, when I try to connect to my own network, the process hangs and nothing happens.

I've tried the usual common-sense options (rebooting the router, making sure settings are correct, etc.). And I've also tried the first of the solutions mentioned here:

This basically involves adding the line:

options ath9k nohwcrypt=1
to the file:

This worked for me on earlier versions of Ubuntu, but is having no effect in 14.04.

The machine I'm using (and older Dell XPS 400) also has a Windows 7 partition, and the same hardware works flawlessly under Windows. I also had Crunchbang Waldorf running on the same setup, and everything worked fine there as well. It's only when I decided to try out Xubuntu that the problem began.

The only other solutions I can find for this issue, other than the one mentioned above, involve using apt to install packages and compile new drivers; however, since the wireless card is what's not working, these are not accessible solutions (I could move my entire desktop rig two floors down in order to plug in ethernet style where my cable connection actually enters the house, but I'd rather not if I can help it!).

I'd certainly appreciate any advice!

Thanks in advance!

Since you can go down 2 floors to where AP is why don't you go down there to see if you can connect to wireless, if youcan, then I would say that it's interference.
I have a Sony Vaio & am at a friends apartment, which I find my laptop almost unuseable unless I'm in the upper portion of the apartment, due to interference. In the lower portion of apt. I get about 1Mbs & if when it's connected I try to go to another page it takes forever.
When at LQ I choose Subscribed Threads, I can cook dinner before it gets there or times out.

SOLVED! Thank you!

Hi Folks:

Thanks so much for your suggestions! Originally I had installed the long-term support version of xubuntu (14.04). Installing the latest version (14.10) seems to have solved the wifi connection issue. So far, everything seems to be working perfectly.
