This issue has been bothered me for a while now. Whenever my WiFi drops, it shows this in the syslog:

Jun 13 19:56:38 hp-ubuntu wpa_supplicant[1008]: wlo1: WPA: Group rekeying completed with 00:23:69:2e:53:57 [GTK=CCMP]

And my WiFi does not automatically reconnect. I need to manually restart network-manager to restore the connection.

Is there a way to prevent this issue? Looking forward to your reply, thanks!

Output: lspci -knn | grep Net -A2

  • Group key should not be the issue. You can disable reniewing group key in the router. It is only for multicast. – Pilot6 Aug 16 '16 at 9:25
  • @Pilot6 Ah, okay. But for some reason it always disconnect the same time it renews the key, so I thought it was causing issues. Do you have any idea what it could be? – Y4kuzi Aug 16 '16 at 14:51

What fixed it for me was going to Edit Connections, choosing the particular connection, going to the IPV6 tab, and setting it to "Ignore".

That looks like IPV6 group rekeying.

Ubuntu has issues with their IPV6 on some systems. Mine worked great for 5 years. Then a after a routine update, it would drop consistently every 20 minutes. Disabled the IPV6, and back in business.


Try wpa_cli log_level warning as root to change default INFO level to WARNING.

Looks like extra config file and wpa_supplicant startup tuning required to make this permanent.

  • I have run the command sudo wpa_cli log_level warning but what do I do at this point? – Y4kuzi Aug 16 '16 at 0:06
