Network error and crash when waking up from suspend

Post by akerenyi » Thu Aug 15, 2019 2:24 am

Hi there!

I have had a problem for the better part of this year. Every time I open the lid on my T450s laptop after suspend/hibernate, it thinks for a few seconds and then displays an error massage: "No Internet Connection". In addition, approx 1 out of 3-4 times even Cinnamon crashes and goes into fallback mode.

I searched the forums but couldn't find a solution to this issue. Any suggestion would be much appreciated!

Here is the output from inxi -Fxz:
