I have AC68u running on Merlin FW (Vx.384.17), out of blue all the lan ports including WAN port are not working (Wifi is fine though) not sure what went wrong.

Code:
[email protected]:/tmp/home/root# robocfg show
Switch: enabled
Port 0:   DOWN enabled stp: none vlan: 2 jumbo: off mac: 00:00:00:00:00:00
Port 1:   DOWN enabled stp: none vlan: 1 jumbo: off mac: 00:00:00:00:00:00
Port 2:   DOWN enabled stp: none vlan: 1 jumbo: off mac: 00:00:00:00:00:00
Port 3:   DOWN enabled stp: none vlan: 1 jumbo: off mac: 00:00:00:00:00:00
Port 4:   DOWN enabled stp: none vlan: 1 jumbo: off mac: 00:00:00:00:00:00
Port 5: 1000FD enabled stp: none vlan: 2 jumbo: off mac: 60:45:cb:67:d6:98
Port 7:   DOWN enabled stp: none vlan: 1 jumbo: off mac: 00:00:00:00:00:00
Port 8:   DOWN enabled stp: none vlan: 1 jumbo: off mac: 00:00:00:00:00:00
VLANs: BCM5301x enabled mac_check mac_hash
   1: vlan1: 1 2 3 4 5t
   2: vlan2: 0 5

I reverted to asus firmware which didn't help. Any pointers will be greatly appreciated.

Thanks
Rajesh

Try a hard reset by holding the reset and WPS buttons at the same time, then applying power and waiting until the LED lights flash in unison (may take a few seconds). Then power off and back on normally. May take several attempts. If that doesn't work, perhaps the switch is physically dead.

I did this but nothing changed
Just to be clear, did you read the instructions for hard reset in the link for your specific router and follow them? If you really did that and nothing's changed, then next you should try finding a replacement power brick, from the same router model if possible.

Yes @Zetto, I clearly followed the instructions mentioned in [Wireless] ASUS router Hard Factory Reset - Method 1 | Official Support | ASUS Global but nothing changed. Am guessing it has indeed bricked.

try another power adapter, if you can find one. There's a slight chance maybe it is causing issues.
