No network connectivity after Fresh Proxmox install

[fdavidg]

Hello,

I have read numerous posts similar to my problem, but I have no idea how to resolve this issue.

I did a bare metal install of Proxmox on a new HDD. The PC had run Win 10, Ubuntu, Debian, Fedora, etc. in a multiboot configuration and network connectivity was not a problem. I replaced the HDD with a new HDD and did a bare metal install of only Proxmox. The install went fine, but I have no network connectivity at all. The install has a static IP of 192.168.1.249. The output of the command
ip ro
default via 192.168.1.1 dev vmbr0 proto kernel onlink
192.168.1.0/24 dev vmbr0 proto kernel scope link scr 192.168.1.249

The output of the command
cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface wlol inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.249/24
gateway 192.168.1.1
bridge ports wlol
bridge-stp off
bridge-fd 0

I hope someone can help me resolve this issue.
Thank you.

wlol looks like a WiFi device, which is not supported by Proxmox: https://pve.proxmox.com/wiki/WLAN . Things (like installing WiFi drivers) will go much easier if you can add an Ethernet network device (possibly via USB) and connect it with a cable to your router.

leesteken, Thank you for your information. It should be wl01 and that is what I thought. I do have a USB to ethernet adapter. How do I go about getting it to work with Proxmox. I do not think it recognizes the device??? I have no network or internet connectivity on this machine at all. Suspect the network card is dead? Any and all help would be appreciated. This is my first Proxmox install, and I have a little familiarity with Ubuntu, Debian and Fedora.

The network does not work automatically and you need to configure it manually. What is the output of ip a on the Proxmox host console? A readable photo would do to figure out what the device is named if it is working/supported.

I hope that picture is readable. If not let me know and I will try again. Thank you for your help by the way!

Try editing your /etc/network/interfaces and use enxc84d4435eec as bridge-ports instead of wlo1. Also add the line iface enxc84d4435eec inet manual under iface wlo1 inet manual. Check networking (using ip a again) after a reboot (and make sure a cable is connected).

leesteken, My network is up and running on my Proxmox server. I can ping the gateway and google.com! THANK YOU! Thank you for all your help. I now understand a little better how Proxmox works and how networking works!
