Ubuntu 16.04 on dell E6430, after upgrade: - after suspend/resume sometimes the network manager cannot connect (but it tries: it keeps associating/de-associating) [before upgrade, the wifi was broken at this stage, cf below] dmesg: [101381.710749] wlan0: authenticate with 42:01:40:59:9f:3c [101381.712600] wlan0: send auth to 42:01:40:59:9f:3c (try 1/3) [101381.714512] wlan0: authenticated [101381.716173] wlan0: associate with 42:01:40:59:9f:3c (try 1/3) [101381.726242] wlan0: RX AssocResp from 42:01:40:59:9f:3c (capab=0x411 status=0 aid=4) [101381.728513] wlan0: associated [101388.076989] wlan0: deauthenticated from 42:01:40:59:9f:3c (Reason: 15=4WAY_HANDSHAKE_TIMEOUT) [101388.104508] cfg80211: World regulatory domain updated: [101388.104511] cfg80211: DFS Master region: unset [101388.104512] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time)
- if I deactivate and then reactivate the wifi, then it reverts to the old bug (where there is only one network available and nothing happens). sudo service network-manager restart repairs everything... The bug is still at this point: [101418.822530] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [101418.869145] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [101423.443499] e1000e: eth0 NIC Link is Down [101426.202627] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [101426.202873] iwlwifi 0000:03:00.0: L1 Enabled - LTR Disabled [101426.210391] iwlwifi 0000:03:00.0: L1 Enabled - LTR Disabled [101426.210491] iwlwifi 0000:03:00.0: Radio type=0x0-0x3-0x1 [101426.434605] iwlwifi 0000:03:00.0: L1 Enabled - LTR Disabled [101426.442165] iwlwifi 0000:03:00.0: L1 Enabled - LTR Disabled [101426.442267] iwlwifi 0000:03:00.0: Radio type=0x0-0x3-0x1 a problem with the /dev/something, no? strange... hope this can be repaired soon. But also in the 14.04 distrib it was sometimes necessary to deactivate/restart the network manager to catch back the signal after resume... good luck, thanks -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574347 Title: [SRU] Re-read the link type if the name changed To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager/+bug/1574347/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
