Hi Julien, i can allocate some of my free time and try to recreate the issue here next week. may be a regression. enabling mac80211 debugs will also be useful. you said that the issue happens without security, and also only when the AP router is already connected by another station. in the other thread it was mentioned that the problem occurs only when its a wireless router. AR9285 has diversity enabled, we need to check if its working properly. also please check whether setting coverage class via iw'improves the situation. iw phy <phyname> set coverage <coverage class> > > Cheers, > Julien > > [0] https://lists.ath9k.org/pipermail/ath9k-devel/2011-October/007055.html > > -- > .''`.
