Whilst per my previous posts i remain perplexed why i now suddenly have to do anything different [given this silly problem began without me making any relevant kernel or software change], i will nevertheless most happily try out your idea... & i sincerely thank you for it.
It's not convenient atm for me to do this test, so i will wait til my tomorrow morning's Resume [tonight before bed i will change the kernel back up to 4.17, reboot, then Suspend it for the night]. Can i just clarify how to do the initial test? Yes i understand about me making a simple bash script that i can run, but that's not necessary yet until it proves to workaround the silly problem. So, for the initial test:
- Is it sufficient that i literally just copy/paste your compound command into Konsole & run it there?
- I presume that i run the command post-Resume [when i see there's no network again], not pre-Suspend [when i already do have my network availability]?
Thanks, will let you know, tomorrow.
I'm not necessarily afraid of systemd, but as per one of my earlier posts, none of my attempts to Enable & Restart [nor Stop & Start] NetworkManager via systemctl succeeded in giving me back my network, with 4.16/.17/.18, post-Resume, since this annoying problem appeared 7 days ago.
