With me the problem always occurs when in a running connection the channel is changed. This may happen in a busy neighborhood, if in the Router (FritzBox 7530) the automatic channel selection (recommended) is selected. It certainly may happen too if a Repeater is in use.
If I switch of and on manually the WIFI, this procedure is treated as a new connection, and the installed password is found automatically with no request, quite as it aught to be. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-applet in Ubuntu. https://bugs.launchpad.net/bugs/1908823 Title: sporadic WiFi aborts with opening a window requesting to enter the WiFi password that is pre-filled Status in network-manager-applet package in Ubuntu: Confirmed Bug description: The WiFi connection is aborted an the nm_applet shows the window to enter the WLAN password. The password is pre-filled an you can click the ok button to reconnect. The error occurs sometimes very often (e.g. 10 times/minute) or seldom (only one per day). The problem occurs in Xubuntu 20.04.1 LTS since update to kernel 5.4.0-56 (5.4.0-58 too). With other Xubuntu versions (e.g. 18.04 LTS) or kernel 5.4.0-54 or earlier the problem did not appear. Other OS (eg W10 or div Android) do not see this problem too.

All hardware that I know show the problem on laptops with Intel WLAN devices. In /var/log/syslog you can find the error beginning with a "wpa_supplicant[xxx]: l2_packet_send - sendto: No buffer space available" entry. Some lines later you see the entry "asking for a new key". The problem can be reproduced by forcing a WLAN reconnect. This happens, when the router changes the channel or when the wifi signal strength tends to modify the way from the computer to the router (direct connect or via a repeater or changing the repeater e.g. in a Mesh). This behaviour ca be seen in the 2,4GHz and in the 5GHz net. In the sent .apport file you see the switch from repeater (2c:91:..) to router (44:4e:..) at "Dec 29 14:18" as the repeater is forced to reboot to produce the error.
