Comment 78 for bug 1585863

"after resume, only a couple of wifi networks will be listed at most, and never the one I use" - that's exactly the symptom I see after resuming my DELL E7450. Also, the Wi-Fi icon is replaced with an "arrow up arrow down" one. `sudo service network-manager restart` reconnects most of the time, but sometimes that wrong icons stays on.

I've just modified `/lib/systemd/system-sleep/wpasupplicant` as described in #64, and will be testing for the next several days. Is a reboot necessary for that modification to take effect?
