I found out that cpu scaling is causing this issue. ** Description changed:
- When I change access points then hibernate and resume I cannot see any - access points. + When I change my cpu frequency to the highest value (2gz) then hibernate + and resume I cannot see any access points. - After rebooting access points come back. + 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. I have tried - ndiswrapper and madwifi drivers and the issue also exists there. + I am using Ubuntu 10.04 with ath9k drivers for AR5008. $ lspci |grep Atheros 0e:00.0 Network controller: Atheros Communications Inc.
