Hello everyone,
I am running an RUTX50 with a German T-Mobile card and the firmware UTX_R_00.07.09.4. As soon as the router gets a little load in mobile operation, the mobile connection breaks down. The router then displays the message “Internal modem is unreachable”. After a restart, the same problem occurs again a short time later. It runs stably when idle, also with an external Internet source on the WAN port.
Kind regards
Jan
