You’ll need to ssh into the router. Enter “logread -f” into the ssh session, then connect your Aria again. The “logread -f” command will print new log lines when a device tries to connect to the router.
For a successful connection, you’ll see lines like these:

If Wifi connection is not successful, you won’t see the DHCP lines.
