Title:
Wifi cant connect after suspend with highest cpu freq set
Status in “pm-utils” package in Ubuntu:
Invalid
Bug description:
When I change my cpu frequency to the highest value (2gz) then
hibernate and resume I cannot see any access points.
I can get wifi working again by:
- rebooting
- changing the cpu scaling to a lower setting then hibernate/resume
- changing the cpu scaling to a lower setting then `sudo rmmod ath9k;
sudo modprobe ath9k;`
I am using Ubuntu 10.04 with ath9k drivers for AR5008.
