I've had this AX-50 for a couple years and had been working flawlessly until yesterday. Now the 5G wireless will not stay connected to any of my devices. I have upgraded firmware to latest version (1.0.14 Build 20240108 rel,42655(553)), have lost count how many times I've re-booted the router, but it continues to kick any device off almost instantly after it connects. The 2.4G works fine with no erros or issues, just the 5G will not connect. The 5G network is visible in the device settings, it is also visible from all my devices in their wireless settings, but no device can connect all of a sudden. Anybody have a suggestion?
