Ever since I updated the firmware from ver1-2-3-P1[20210719-rel14861 to the latest 1.3.4 Build 20230906 rel.74809(5553) the router has been dropping the internet randomly, 1-3 days between dropping. Never did this with the older firmware. Turning off the power and turning it back on fixes it until the next time, works fine until then. It is connected to a fiber modem PLDT Huawei EchoLife HG8145V5 using a static IP out of the DHCP range. Double NAT AX11000 is set up to a different IP 192.168.2.1 used for WiFi and 2 LAN connections no MESH or any other options. No errors are showing up in the system logs on either router (attached). I was gone for a month and bypassed the AX11000 and connected my fiber modem router to my Linksys EA8500 as an access point no loss of internet happened. I can log in to the AX11000 when this happens but the connection is very slow (the switch and radios are like dead). BTW AX11000 is connected to an APC UPS.

Things I have done:

-New Lan cables on all connections.

-Reset to factory defaults, re-installed latest firmware and set up router manually (not from backup).

Still happening!
