SUMMARY

When I resume my laptop from being asleep (or whatever you call it, when it "shuts down" from being idle too long, or when you close the lid), the network manager doesn't seem to restart, or have died at some point.

I can't see or connect to any wifi networks.

I've tried to log out the current user, and log back in, but this doesn't help.



STEPS TO REPRODUCE
1. Connect to a wifi network
2. Put laptop to sleep for extended time
3. Open laptop.

OBSERVED RESULT
- Does not connect to wifi.
- Does not seem to enable wifi radio.
- Does not find/display any wifi connections (except those already stored in the list of "known" networks).

EXPECTED RESULT
- Wifi should restart/activate when laptop resumes function.

This unfortunately doesn't seem like an issue in our Plasma applet. Most likely it's a driver issue, which I would suggest to report to NetworkManager directly.

Please do so here: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/issues
