Starting Point: I have two 64 bit systems on my home network that had Debian 11 loaded. I successfully configured both to WOL from a full shutdown by sending the proper magic packets using apps from any of my other home devices (laptops, tablets, phones). This was the way things worked for a very long time; wake-on-lan to start the computers when ever I needed them, and letting CRON shut them down at the end of the day.
First Change: In order to update a piece of insignificant software to the latest version if was recommended that I dist-upgrade linux to Debian 12 so I upgraded one of the Debian 11 systems to Debian 12 to make sure everything worked before updating the other. After updating the first machine I discovered that this machine no longer reacted to WOL commands. Checking the configuration of the Network interface I found that the -g option had been reverted to the -d option on the card. Also it appeared that a few other network settings had been changed. I had already noticed and made some adjustments to the systems when the interface renaming occurred some time before so I can't believe that is the issue. I have made changes that seem to get the card to show WOL enabled after a reboot but it still won't react to WOL commands after shutdown. So that is my first issue.
Next Change: On the second machine I chose to NOT update to Debian 12 and everything was fine until a few days ago when the system did a normal update where it updated the kernel among other things on its own, as I had set it to do. Following this update I found that the second system was also now affected by the refuse to react to WOL commands. Again I checked the configuration of the network card and found the WOL again turned off and no way to get the machine to accept WOL commands after shutdown.
So my question is what changed that has disabled my ability to use WOL on these machines - NO nothing has changed in my BIOS settings and they are still set to WOL but something has changed with Debian that has disabled the WOL from a full shutdown condition. It is probably something basic that I missed in my searches online but maybe someone out there ran into similar problems and has a fix for me.
Thanks
