coexistence problem between bluetooth and atheros (ath9k related)

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..)

I bought a TP WN722N usb wireless dongle.

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

Hi All,

We are finding it difficult to make the wireless work in my friend's laptop. It is a Dell Inspiron. Running on Ubuntu 12.04 with 3.2.0-30-generic kernel.

lspci | grep -i ethernet

Code: 03:00.0 Ethernet controller: Atheros Communications Inc. AR8162 Fast Ethernet (rev 10) Earlier rfkill was showing that the wifi was hard blocked. However wired internet was working fine.

hi,

I'm having problems with my network driver. 1. at first installation, I did not have either wireless or wired networks. 2. I updated my system using a network USB dongle, and got proprietary drivers, installed it 3.

i've been using ubuntu since intrepid, but since upgrading to karmic i've been having problems with my wireless card. to be honest it was never perfect but where before i would maybe get one or two disconnections a week, it now has kittens any time i ask it to do anything other than load a simple web page.

Try installing a more recent kernel - towo, liquorix or debian experimental. smxi can help.

Upgrade your kernel. Either via smxi to liquorix or towo, or via experimental to Debian's 3.6.

Hi everyboy!First consideration, sorry for my bad english...but google translate and the dictionary helps me to write the answer.I have one notebook Packard Bell with this wireless lan device:07:00.0 Network controller: Atheros Communications Inc.
