Hey, I recently bought an XE300 (Puli). I added an LTE connection via a new Profile and upgraded the router to the latest firmware. The router boots up and then goes online with the LTE modem. The connection is shared. Both Wifi and 4G work. However, the admin interface shows the modem as unavailable.
System log shows
"Tue May 6 12:17:01 2025 daemon.err modem_AT: (modem_AT.c:319) The /dev/ttyUSB3 does not open, continue to try."
I attached Screenshots and logs. As you will see, the cellular connection is active, but cannot be configured via the admin interface.
