Annoying factoid, the modern naming of Linux network interface cards provides a consistent way of naming the devices. But not a permanent one.
Taking advantage of Rimuru’s old dual port 10G USB-C card that I replaced with a Thunderbolt 4 card, happily works. But as a side effect this means that enp3s0 and wlp4s0 are now enp4s0 and wlp5s0, which as you might expect breaks the networking configuration for both interfaces.
Because why the fuck would you expect devices to retain their topology just because they happened to be soldered to the board? On the upside at least it became obvious what was going on when I inspected the files in /etc/NetworkManager/system-connections and noticed that the digits had changed.
I’m guessing that since Zeta’s lone PCI-E slot is an x16, it ends up numero uno. It just so happens that I have an PCI-E x4 card plugged in with a USB controller instead of a GPU, because the machine’s jobs are all server related. Although, I bet she would make a dandy little gaming box in as much as a 2-slot wide GPU and a SFX PSU can actually handle anything modern and juicy. Especially if Valve was to you know, release StreamOS 3.x for PC instead of Steam Deck only
