### Describe the bug We've been able to connect the Pi to the surface laptop with a single Ethernet patch cable before (no router). Try to get this working again. This [stackexchange](https://askubuntu.com/questions/1525078/how-to-connect-two-ubuntu-24-04-hosts-over-ad-hoc-ethernet) question might help, but I think the first answer is wrong (modern devices don't need crossover cables).
