You have been subscribed to a public bug: Some wifi adapters kept asking for a password when MAC address randomization was enabled.
I reported this to Realtek, and they gave me a patch for wpa_supplicant, which fixes the issue. I asked Realtek to report this upstream to wpasupplicant, and they did, the commit is: http://w1.fi/cgit/hostap/commit/?id=7546c489a95a033c78331915fcdfa0e6fd74d563 It would be very nice to cherrypick that for Focal. I uploaded it as a merge request below, and I tested that it fixes the issue with adapters based on the following chipsets: ath9k, rtl8812au, rtl88x2bu and rtl8821cu To reproduce this: Ubuntu's network-manager defaults to "MAC randomization disabled", I think as a workaround to this specific issue. This is defined in two places: - wifi.scan-rand-mac-address=no in /etc/NetworkManager/NetworkManager.conf - Some specific drivers in /usr/lib/NetworkManager/conf.d/no-mac-addr-change.conf. With these, the problem happens in around 10% of the cases. To be able to reproduce it in 100% of the cases, it's best to remove these Ubuntu workarounds. So: - Set "wifi.scan-rand-mac-address=yes" in /etc/NetworkManager/NetworkManager.conf - Remove /usr/lib/NetworkManager/conf.d/no-mac-addr-change.conf. - systemctl stop network-manager - killall wpa_supplicant - systemctl start network-manager Then insert a USB wifi adapter that results in a big name with 15 characters like wlx74ee2ae2436a and try to connect to a wifi network. It will keep asking for a password. Then apply the patch, run the 3 commands above to restart network- manager, and verify that it can now connect properly. ** Affects: wpa (Ubuntu) Importance: Undecided Status: Triaged ** Tags: patch -- Fix RTM NEW/DELLINK IFLA_IFNAME copy for maximum ifname length https://bugs.launchpad.net/bugs/1867908 You received this bug notification because you are a member of Desktop Packages, which is subscribed to wpa in Ubuntu. -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
