Sorry, but I have to partially rectify that: It works, if the time the machine was suspended is short, as it was when I did that testing. But I noticed it failing, when the machine was hibernated for some hours. I easily can reproduce that, when I reboot the AP while the notebook is down (btw: AP is TP-LINK TL-WR1043ND running OpenWRT backfire 10.03.1, also using ath9k). When I do this (hibernate notebook, reboot AP, resume notebook check connectivity) with 3.4-rc2 and your test.patch it fails in 100% of cases. With 3.4-rc2 and c1afdaff90538ef085b756454f12b29575411214 reverted the same works in 100% of cases. > But I agree with Ben and Sergio that it does NOT help with the issue > in 3.3.1 we all see. I mixed up some mails and actually thought Ben had already answered regarding your patch, but that is not true. -- MfG, Michael Leun
