Internet does not come back if I unplug and re-plug ethernet -?

@Tamsy just wanted to apologize to you for anything that may have happened before or anything I may have said before, tried to send you a private message but that is turned off. BTW marking this as solved as well as the best resolution was to reinstall from scratch using this - and your additional guide here for eupgrading from Debian 11 to 12 was genius! Please don’t now be a stranger - ?
