Bug Description
Seemed related to other bugs, but this is a new issue. Hardware is a Thinkpad R51e with Atheros chip:
*-network
description: Wireless interface
product: Atheros AR5001X+ Wireless Network Adapter
vendor: Atheros Communications Inc.
physical id: 2
bus info: pci@0000:04:02.0
logical name: wlan0
version: 01
serial: 00:16:ce:61:40:aa
width: 32 bits
clock: 33MHz
resources: irq:22 memory:
Driver worked fine in 9.10, and on new installation of 10.04. On upgrading kernel from 2.6.32-21 to 2.6.32-22, problems started to occur. Initial connection to WPA2 access point is fine on boot up. After around 1 hour, connection will drop and cannot be re-negotiated. Restarting network is ineffective. Change to wicd is ineffective. Rebooting is the only way to get a connection again.
Rebooting into kernel 2.6.32-21 also fixes the problem.
WORKAROUND: if using WPA/WPA2-personal security mode had to have the encryption on my router set to AES only.

Hi Plutocrat,
If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text. Please let us know your results.
Thanks in advance.
