How to start or stop network service's like "lo, enp12s0....."

[t.m]

i get status on "lo" UNKNOW
enp12s0 - DOWN
wlp6s0 - down
vmbr0-UNKNOW

[skukunin]

ip link set dev wlp6s0 up

Also, UNKNOWN status might be ok, depending on the interface type. For vxlan interfaces it shows UNKNOWN even if they are working

 

[t.m]

still not working.
try it again plus restart still down

you can check your lan interface names now.
My Proxmox Server all are running without a problem.
