I guess you tried the power saving "off" option in this post? https://ubuntuforums.org/showthread.php?t=2348161 as well as other possible solutions?
Yes, I have, thanks. It's kind of annoying that the maintainer said that firmware more recent than that post made all the problems go away and superseding the need to do modprobe/power management tricks. I now have the newest firmware, plus /etc/modprobe.d/rtl8821ae.conf : options rtl8821ae fwlps=N and /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf : [connection] wifi.powersave = 2 but still I get dissociations every 10 minutes or so. It's particularly annoying to see logs like this: [Sat May 13 12:50:39 2017] wlp4s0: deauthenticated from 14:91:82:2e:8b:51 (Reason: 2=PREV_AUTH_NOT_VALID) [Sat May 13 12:50:42 2017] wlp4s0: authenticate with 14:91:82:2e:8b:51 [Sat May 13 12:50:42 2017] wlp4s0: send auth to 14:91:82:2e:8b:51 (try 1/3) [Sat May 13 12:50:42 2017] wlp4s0: authenticated [Sat May 13 12:50:42 2017] wlp4s0: associating with AP with corrupt probe response [Sat May 13 12:50:42 2017] wlp4s0: associate with 14:91:82:2e:8b:51 (try 1/3) [Sat May 13 12:50:42 2017] wlp4s0: RX AssocResp from 14:91:82:2e:8b:51 (capab=0x511 status=0 aid=13) [Sat May 13 12:50:42 2017] wlp4s0: associated [Sat May 13 12:50:42 2017] wlp4s0: Limiting TX power to 20 (23 - 3) dBm as advertised by 14:91:82:2e:8b:51 The network had long be unreachable before the first 'deauthenticated' at 12:50:39, but there were no log messages given. Then it decides to reconnect as if nothing had gone wrong previously. cheers, Stewart
