Warning - ath9k breaks with the 3.2 kernel update

Well, I did something like five fresh installs, but at last I found the problem.

Wep and ath9k has been buggy for me for a long time now - sometimes it works, sometimes it doesn't. Never got around it, adding "options ath9k nohwcrypt=1" into /etc/modprobe.d/ath9k.conf seemed to work for some time. You could give it a try. The network I have problems with is at the university, they use wep + vpn to connect.

Hello all,

I'm running Kubuntu 12.10, with the D-link DWA-556 network adapter

As the title suggests, I'm using the ath9k driver, and the speeds are just abysmal, often less than 100 kbps. I've tried several fixes... and nothing has worked for me.

I have a Vostro 2520 and not sure how to enable wireless on my machine.

All,

I'm running 12.04 (64-bit) with kernel 3.5.4 and all is well, very well actually, with the exception of one thing. I can not for the life of me get my wifi to connect at N-speeds. I also have a MacBook sitting right beside me and it connects just fine with the double the wife speed I have. I have an Atheros AR9485 Wireless N card in the laptop (Asus N56V).

Running Ubuntu 12.04 on an Acer Aspire 5750Z with an Intel Pentium

I upgraded the kernel from 3.2.0-35 to 3.5.0-21 to fix a problem with power management (It would freeze my system when I booted from battery and whenever I unplugged the AC adapter) and it worked just fine.

But..

I started experiencing all sorts of network problems (slow, dropped connections, froze when turning off wifi, etc..)

When i open up firfox i get a kernel panic saying that Ath9k wireless crashed any idea on how to fix

thanks
