Hi guys, have been looking at connected clients and spotted something out of the ordinary, a wired device but my LAN port 1 is currently connected to my powerline adapter and nothing else, does anyone recognize this manufacturer? Currently block its internet access but would like to prevent it from seeing rest of my device. Any advice is appreciated.

Router : AX58U, running merlin latest firmware

Edit: turns out to be a lenovo thinkpad laptop that was disconnected from the router, I hibernated the laptop then unplugged the ethernet cable few hours ago, however it still shows up as wired device under the router's connected clients


Thank you.

I have turned off the powerline adapters that is connected to the LAN port as well as the ONT modem that is connected to the WAN port of the router,
that wired device still shows up

Edit: Resolved, turns out it was a lenovo thinkpad laptop but its weird because I disconnected it hours ago and hibernated the laptop but it still shows up in the router as connected client.
