RT-AC86U not detecting a cable

[Markfree]

I had a power outage and after that my AC86U router stopped detecting any cable I plug in, at any port, including WAN port.
I can only access the router UI using Wi-Fi.

While testing, by disabling and enabling my PC network adapter, the router logged these messages bellow once for LAN 4, but still showed it as "unplugged".

I'm not sure what that "Deep Green Mode" is but I disabled it using.

# pwr config --dgm off

May  5 02:08:01 kernel: <=== Deactivate Deep Green Mode
May  5 02:08:01 kernel: Deep Green Mode feature changed to disabled (DGM status: deactivated)

I also did completely reset the router but with no avail. It still won't detect any cable. Even Asus restoration tool didn't work.

Is there anything I can do to restore that conectivity?

Try leaving it turned on, but unplugged from the power adaptor. For at least half an hour or more. Also, be sure you unplug all USB and Ethernet cables too.

If the following link doesn't help get results, you may need a new router.

ax88 packet loss

Hi, I recently upgraded to the ax88 router and have been having connectivity issues (laggy, jittery connections). i checked, and see anywhere from 20% to 50% packet loss, when measured with ping 8.8.8.8 or 1.1.1.1 from multiple clients. this happens if client is connected to router via wifi...

I tried your steps one by one but it won't detect any ethernet cable.
I guess I'm with a paper weight now.

Time for a new router then.

Or maybe
