I've been using this router for 2 years with few issues. Two days ago, I lost internet connection (Solid Red LED). I restarted the modem and router, and all was good. Then one day ago, the solid red LED appeared, but restarting the modem and router did not work. I had an internet connection when the PC was hard-wired to the modem, but when the modem was hard-wired to the router WAN port and PC hardwired to router LAN, I could not get the internet. Tried numerous fixes to no avail, however, at some point, I got an internet connection while the PC was hardwired to the router LAN port. Once that occurred and I could get into the AX11000 dashboard and checked for firmware updates (mine was current).

The problem seemed solved for one hour, although I have no idea why. Then, the router randomly restarted. Now it restarts every few minutes or for more than an hour.
