Proxmox does not reconize connexion

[nitroh21]

Hi !

I have a question : i want to install proxmox on my laptop (asus fx503v. I followed different tutorial and i can start it, but, when i want to go online, for exemple to right apt update, he can't acces to debian server because there is no connexion. In short, my laptop can't access to internet. I plug an Ethernet cable (RJ45). I tried with 2 kind of adapter and it acctuelly not work. So, does anyone know why proxmox does not reconize my internet cable ?

The gateway in /etc/network/interfaces is not in the correct network. You have to change 192.168.100.27 to the ip your router is. Usually it is the first IP on the network, so 192.168.0.1, but that might be different for you.
