Same problem here. If I use my WiFi as a normal interface, no issues at all. I have wired ethernet and use this as a hotspot for some devices and once every second I see:

When running as AP I would like to disable periodic scanning. cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=20.10 DISTRIB_CODENAME=groovy DISTRIB_DESCRIPTION="Ubuntu 20.10" Happened on 20.04 as well. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to wpa in Ubuntu. https://bugs.launchpad.net/bugs/1824118 Title: wpa_supplicant executes hundreds of failed atempts in a second Status in wpa package in Ubuntu: Confirmed Bug description: I use my computer to create a wifi hotspot to my local wired network. Whenever I do so I get short hangs that last for about a second every few minutes. Looking into the syslog in /var/log/syslog I get the output at the end of this message. I have tried my best to look for an answer to this bug, but the reported bugs on wpa_supplicant are all for other ret codes.
