I need some help with an ASUS AX-RT88U router that seems to have stopped working. I have had this router in place and working fine for almost 1 year. Sometime in December, a firmware update occurred and it stopped working. No other setting was changed. It would cycle saying "Internet Disconnected," "WAN Unplugged," and "DHCP does not function correctly." At that time, I unplugged everything and restarted. Still nothing. I contacted my cable service provider and everything seemed to be fine there. I checked and swapped the cables to make sure they were ok. I was using an Aimesh setup and changed one of the nodes (RT-AC68U) to a primary and everything worked. I factory reset the AX88U and tried again. Still nothing. I called ASUS and we went through some additional trouble shooting steps including changing frequency from aggressive to normal, and still had no luck. At that time, ASUS rep said he thought it was a bad WAN port and set up a RMA. Today, I received a new RT-AX88U and plugged it all in and to my dismay, I got the same errors. Again, I unplugged and reset everything. I swapped cables. I swapped routers, and the AC unit immediately works. I'm at a loss. There is no way that I received another new router with a bad WAN port. This has to be a firmware or setting issue, but I can't figure out what it would be. I would appreciate any help or light that you may be able to shine on the issue.
Thanks
