no network after wake from sleep, also no messages file in /var/log

after wake from sleep my computer has no network, I tried service network restart but didn’t help. I can ping my router but cannot ping any public IP like e.g. = google DNS. It’s really anoying. It happens pretty often after waking from sleep and I’ve to restart - it happens to be some serious bug. And what’s even more worrying that I’ve no messages fiel in

  • so no system logs
