basically all my pc connected with ethernet to the modem, sometime work and sometime don't, when they don't i get the error "ip configuration not valid"

This is happening from when i changed my modem/internet connection , probably is configured bad but i have no idea of how to check it

This problem pops up only on pc connected with ethernet, all wifi device are connected and have no problem

also if i change the spot of the ethernet cable multiple times then it work again, or if i do right click on the internet icon in the bottom right of windows and then "troubleshooting"

Does anyone know why is happening and how i can fix it? thanks!

First thing to do is to make sure all your computers are set to obtain IP address automatically.
If that's all good, then look to the modem, well actually router. A modem would only allow one computer to connect. Since you have more than one computer connecting, your device is a router. (The router may have a built in modem.) If you made changes to the default modem/router settings - what changes did you make?
