RT-AX86U on 3.0.0.4.386_45898-gfa90458. Several days ago I upgraded to the RC3-2 Beta. The router rebooted after the upgrade and after about 30 seconds started into a boot loop. I was able to get a reflash of 3.0.0.4.386_45898-gfa90458 started, did a hard factory reset and configured manually.
Today I decided to try again. Same boot loop. Powered off the router, did a hard factory reset and began to configure manually.
Changed the following in this order:
Changed the DHCP start to 192.168.50.10
Changed
DST time zone changes ends
WIFI set to WPA2-Personal/WPA3-Personal
WAN - static DNS, DoT, enabled Auto prevent DoH, disabled UPnP
Enabled DDNS and set port forward for one LAN client
Enabled AiProtect
Enabled QOS
Enabled DDOS protection
I paused a couple of minutes after each of the above. So far so good!
When I disabled WPS the web gui locked up and the router started boot loop again.
Once again I flashed back to 386_45898, hard factory reset and reconfigure.
