Maybe the solution is easy and I'm just stupid, but I configured my raspberry pi on my home router (192.168.0.1/24) using ethernet and gave it a static ip of 192.168.0.150. Now I changed places and I'm working with a router with an ip range of 192.168.8.0/24.
Now even if I connect the raspberry pi via ethernet to the router and nmap the network it doesn't show up ? How do I connect to it ? XD
