USB Lan Adapter

[luke94x]

Hello

I have two usb LAN adapters, beacause I own intel nuc which has only one onboard lan port. Next thing - I have OPNsense virtual machine which is working perfectly.
I have two USB LAN adapters that carries the same chipset Realteak 8531B. One usb lan adapter is responsible for LAN and its working well, the second should be backup WAN which is not working at all (when i connect modem to pc it works like a charm). Before manually setting the port up it was Active:No despite physical connection, after setting the port up by the command it went to Active:Yes but it is still not working. Anyone knows what can we do about it?

Hi, this is likely a Realtek driver issue — RTL8531B uses the r8152 module which can be unstable on Proxmox.

Check with ethtool -i enx00e04c680835; if wrong or failing, install r8152-dkms (or r8168-dkms) and test direct IP (no bridge) to confirm.

Also try a different USB port or powered hub — NUCs often underpower USB NICs.

Thanks a lot. I have switched to another usb port and turned off Intel Dynamic Power Technology, also turned on Power on usb on S4/S5 state and it worked. Dunnno which one helped but one of this for sure. Thanks a lot readyspace!!
