Title: wifi network keeps disconnecting Status in linux package in Ubuntu: Confirmed Bug description: I'm running Ubuntu 20.04 with the latest updates on a Thinkpad X220. Since about a week I keep having network disconnects. I am using an Intel Corporation Centrino Advanced-N 6205 wifi chip. Before it's been working great. There seem to be others with this recent problem. https://askubuntu.com/questions/1298278/i-keep-getting-disconnected $dmesg shows: [35764.191444] IPv6: ADDRCONF(NETDEV_CHANGE): wlp3s0: link becomes ready [35764.207135] wlp3s0: Limiting TX power to 20 (20 - 0) dBm as advertised by 5c:49:79:33:f5:69 [35770.664591] e1000e: enp0s25 NIC Link is Down [35823.702523] wlp3s0: disassociated from 5c:49:79:33:f5:69 (Reason: 33=DISASSOC_QAP_NO_BANDWIDTH) [35823.949141] wlp3s0: authenticate with 5c:49:79:33:f5:6a [35823.952112] wlp3s0: send auth to 5c:49:79:33:f5:6a (try 1/3) [35824.027366] wlp3s0: authenticated [35824.028058] wlp3s0: associate with 5c:49:79:33:f5:6a (try 1/3) [35824.031316] wlp3s0: RX AssocResp from 5c:49:79:33:f5:6a (capab=0x1511 status=0 aid=3) [35824.049972] wlp3s0: associated [35824.051644] wlp3s0: deauthenticating from 5c:49:79:33:f5:6a by local choice (Reason: 1=UNSPECIFIED) [35827.875982] wlp3s0: authenticate with 5c:49:79:33:f5:69 [35827.883980] wlp3s0: send auth to 5c:49:79:33:f5:69 (try 1/3) [35827.890394] wlp3s0: 5c:49:79:33:f5:69 denied authentication (status 34) [35828.966804] wlp3s0: authenticate with 5c:49:79:33:f5:6a [35828.971132] wlp3s0: send auth to 5c:49:79:33:f5:6a (try 1/3) [35829.043823] wlp3s0: authenticated [35829.044820] wlp3s0: associate with 5c:49:79:33:f5:6a (try 1/3) [35829.047162] wlp3s0: RX AssocResp from 5c:49:79:33:f5:6a (capab=0x1511 status=0 aid=3) [35829.065508] wlp3s0: associated [35829.144604] wlp3s0: Limiting TX power to 23 (23 - 0) dBm as advertised by 5c:49:79:33:f5:6a [35901.739236] wlp3s0: disconnect from AP 5c:49:79:33:f5:6a for new auth to 5c:49:79:33:f5:69 [35901.758760] wlp3s0: authenticate with 5c:49:79:33:f5:69 [35901.762063] wlp3s0: send auth to 5c:49:79:33:f5:69 (try 1/3) [35901.765779] wlp3s0: authenticated [35901.766059] wlp3s0: waiting for beacon from 5c:49:79:33:f5:69 [35901.831428] wlp3s0: associate with 5c:49:79:33:f5:69 (try 1/3) [35901.837432] wlp3s0: RX ReassocResp from 5c:49:79:33:f5:69 (capab=0x1431 status=0 aid=8) [35901.857282] wlp3s0: associated [35901.859310] wlp3s0: deauthenticating from 5c:49:79:33:f5:69 by local choice (Reason: 1=UNSPECIFIED) $journalctl --follow showed this: Dez 09 20:29:05 meschi-ThinkPad-X220 wpa_supplicant[1012]: wlp3s0: Associated with 5c:49:79:33:f5:69 Dez 09 20:29:05 meschi-ThinkPad-X220 wpa_supplicant[1012]: wlp3s0: CTRL-EVENT-SUBNET-STATUS-UPDATE status=0 Dez 09 20:29:05 meschi-ThinkPad-X220 wpa_supplicant[1012]: wlp3s0: CTRL-EVENT-REGDOM-CHANGE init=COUNTRY_IE type=COUNTRY alpha2=DE Dez 09 20:29:05 meschi-ThinkPad-X220 wpa_supplicant[1012]: l2_packet_send - sendto: No buffer space available Dez 09 20:29:05 meschi-ThinkPad-X220 kernel: wlp3s0: deauthenticating from 5c:49:79:33:f5:69 by local choice (Reason: 1=UNSPECIFIED) Dez 09 20:29:05 meschi-ThinkPad-X220 wpa_supplicant[1012]: wlp3s0: CTRL-EVENT-DISCONNECTED bssid=5c:49:79:33:f5:69 reason=1 locally_generated=1 Dez 09 20:29:05 meschi-ThinkPad-X220 wpa_supplicant[1012]: wlp3s0: WPA: 4-Way Handshake failed - pre-shared key may be incorrect Dez 09 20:29:05 meschi-ThinkPad-X220 wpa_supplicant[1012]: wlp3s0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="wifi-name" auth_failures=1 duration=10 reason=WRONG_KEY Dez 09 20:29:05 meschi-ThinkPad-X220 wpa_supplicant[1012]: wlp3s0: CTRL-EVENT-REGDOM-CHANGE init=CORE type=WORLD Dez 09 20:29:05 meschi-ThinkPad-X220 NetworkManager[141586]: <info> [1607542145.0780] device (wlp3s0): supplicant interface state: associating -> 4-way handshake Dez 09 20:29:05 meschi-ThinkPad-X220 NetworkManager[141586]: <warn> [1607542145.0781] sup-iface[0x560dbca5e1e0,wlp3s0]: connection disconnected (reason -1) Dez 09 20:29:05 meschi-ThinkPad-X220 NetworkManager[141586]: <info> [1607542145.0833] device (wlp3s0): supplicant interface state: 4-way handshake -> disconnected Dez 09 20:29:05 meschi-ThinkPad-X220 NetworkManager[141586]: <info> [1607542145.0849] device (wlp3s0): Activation: (wifi) disconnected during association, asking for new key Dez 09 20:29:05 meschi-ThinkPad-X220 NetworkManager[141586]: <info> [1607542145.0851] device (wlp3s0): state change: activated -> need-auth (reason 'supplicant-disconnect', sys-iface-state: 'managed') To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1907493/+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
