Bricked 86u - only LAN Port 4 LED lights up

[Grimani]

Not sure what happened but my main 86u just died. If I plug in power the LAN Port 4 LED lights up and nothing else. Connected a PC to that port and ipconfig still shows it as “Media disconnected”.

Tried leaving it off for awhile, tried powering on while holding reset or WPS button, tried using a different power plug, nothing works.

Any ideas what happened? Has anyone seen the LAN Port 4 LED issue? Was running Merlin 384.11_02 but I didn’t try to update the firmware

I have had two 86u's die in the last couple of months but mine show three LEDs. Each time I RMA the repair report states, "Abnormal WAN/LAN connected port." I'll have a third router tomorrow.

I bought a new 86u and noticed that the boot sequence has the LAN Port 4 light up, then a bunch of other lights including Power. I guess mine has some corruption such that the boot sequence is disrupted. No idea how that could have happened as it was working fine for weeks if not months before.
