Comment 28 for bug 1666432

I experienced the same problem (wired AND wireless both down) on KDE Neon 18.04

Tried several things
- plug in a LAN cable
- restart network service
- 2 reboots
- checked that my router was not down (I had internet access on my cell phone wifi)

The laptop is dual boot W10-KDE Neon
Booting W10 --> I have network connection again.
Boot KDE Neon again --> network wifi and Ethernet works again

Unfortunately I cannot provide debug/error msgs as the problem was quickly solved by booting W10
and up to now it has not occured anymore.

The only info I can provide is that it happened a few hours after doing updates.
