Public bug reported: System has a Realtek network card, so r8169 driver is used.
The behaviour occurs under the following circumstances: $ sudo ethtool enp1s0 reports Supports Wake-on: pumbg Wake-on: d If in this case I send the system to standby (ALT-key plus pause symbol from the control dropdown) then the system goes to standby. After waking up the system the network connectivity is lost and the control panel for network settings reports "cable disconnected". The strange thing is: If I set the WOL properties to g with $ sudo ethtool -s enp1s0 wol g and do exactly the same, then the problem does not occur. I assume there is a bug in the standby handling of the r8169 driver because network connectivity shouldn't get lost if WOL is disabled.
