[SOLVED] Lost network connection to proxmox after dual boot with windows

[kaleaves]

Hi All

I am new to using PVE and studying linux. Please forgive my ignorance and bad english.

I want to build a multi function server at home which can gaming , video editing and cloud storage. Therefore, I built a PVE server run it very well without gpu. Then I install a new gpu for Passthough. Before it, I tested the gpu based on windows with the same machine different hard disk and no trouble.

After that, I insert PVE hard disk back into the machine everything seem fine until I cannot access to the Web-GUI from other machine.
Therefore I look into command ip r which show the ip linkdown. I also checked the interfaces has nothing special
auto lo iface lo inet loopback iface enp3s0 inet manual auto vmbr0 iface vmbr0 inet static address 10.0.1.(XX)/24 gateway 10.0.1.1 bridge-ports enp3s0 bridge-stp off bridge-fd 0 iface wlp4s0 inet manual

Thank You

Best Regards,

Kaleaves

The name of the network device enp3s0 may have changed, because it depends on the PCI ID which can shift by one when you add a PCI(e) device.
What is the output of the console command ip a? You need to change the two occurrences of the old name to the new name (probably enp4s0).

PCI ID did change to enp4s0. Should I use nmcli to update config?

I don't know nmcli. I always use an editor (like nano) to edit /etc/network/interfaces and reboot.
