Hi
1) When using the current kernels 4.13.0-16-generic or 4.13.0-16-lowlatency it is insofar reproducible, that it happens most of the time (I'd say more than 50%).
But not every time, that's why I'm not confident to say the bug is fixed after one or two unlocks.

2) Yes, I think it only happens after suspend though. When I lock the screen and the computer goes into power save mode, then this would happen. If I only lock it and immediately unlock, this is not a problem.

3) I installed the rc7 and indeed the internet works with it. I'll be able to use it on a full work day on Wednesday. I'll report back on the end of the day Wednesday.
