Comment 23 for bug 1778946

I've manually applied the patch proposed in comment #22 to my Ubuntu 18.10 desktop, and I can confirm that it fixes the issue for me. I haven't seen any regression either, although my testing has been very limited so far.

I've been experiencing this bug ever since Ubuntu 18.04 when disconnecting from my employer's Fortinet SSLVPN (I'm using the network-manager-fortisslvpn package). My previous workaround was to force my wifi up again (even if it was not down) after closing the VPN connection (nmcli c up $my-ssid).
