I don't have that computer handy, but I have another one I use currently which is affected by the same issue. This computer is running Ubuntu MATE 19.04, network-manager-gnome version 1.8.20-1ubuntu1.
Changing the log level to debug I see the following entries from NetworkManager: Jul 21 14:41:37 Comcast NetworkManager[976]: <debug> [1563734497.6525] device[0x561d1f3660f0] (wlp2s0): wifi-scan: scanning requested but not allowed at this time Jul 21 14:41:37 Comcast NetworkManager[976]: <debug> [1563734497.6527] device[0x561d1f3660f0] (wlp2s0): wifi-scan: scheduled in 43 seconds (interval now 43 seconds) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1800968 Title: nm-applet only show current wifi connection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1800968/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
