I'm having this problem on Ubuntu 16.04 with 4.4.0-29. It occurs consistently every time after a reboot when I open Chromium (50.0.2661.102-0ubuntu0.16.04.1.1237) and play a YouTube video. It will disconnect once (about 3-4 minutes into a video) an when I re-connect to the same WiFi AP it will stay connected.

Wireless worked flawlessly in 9.04 and 9.10. My other computers still running 9.10 don't have any problem on the same wireless routes. Just upgraded to 10.4 beta and often runs into these two problems. 1) after resuming from suspend, it cannot connect. Looking at daemon.log I see: NetworkManager: <info> (wlan0): supplicant connection state: 4-way handshake -> associated aristotle wpa_supplicant[1055]: WPA: Could not verify EAPOL-Key MIC - dropping packet aristotle avahi-daemon[911]: Registering new address record for fe80::21c:bfff:fe08:704a on wlan0.*. aristotle wpa_supplicant[1055]: WPA: Could not verify EAPOL-Key MIC - dropping packet aristotle wpa_supplicant[1055]: WPA: Could not verify EAPOL-Key MIC - dropping packet 2) sometimes it just disconnect. This seems to be related to traffic, it only happens when streaming video from the net (youtube, vimeo, etc...). Doing a tail -f on daemon.log, this appears at the exact time that I loose my connection: wpa_supplicant[1055]: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: network-manager 0.8-0ubuntu3 ProcVersionSignature: Ubuntu 2.6.32-21.32-generic-pae 2.6.32.11+drm33.2 Uname: Linux 2.6.32-21-generic-pae i686 Architecture: i386 Date: Sun Apr 25 10:44:32 2010 IpRoute: 192.168.2.0/24 dev wlan0 proto kernel scope link src 192.168.2.173 metric 2 169.254.0.0/16 dev wlan0 scope link metric 1000 default via 192.168.2.43 dev wlan0 proto static ProcEnviron: PATH=(custom, no user) LANG=en_CA.utf8 SHELL=/bin/bash SourcePackage: network-manager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/569841/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
