I’ve got RUT241 Modems with the latest firmware.
One of them doesn’t get an answer to udchp renew.
Usually I get this every hour in the logs:
389 Wed Jun 4 15:42:34 2025 daemon.notice netifd: mob1s1a1_4 (4343): udhcpc: broadcasting renew
390 Wed Jun 4 15:42:34 2025 daemon.notice netifd: mob1s1a1_4 (4343): udhcpc: lease of 172.31.196.114 obtained from x.x.x.x, lease time 7200
The other modem just doesn’t get the lease information. Retries of the renew later are not successful either until the lease times out and then there is one final discover and then no connection until reboot.
I put that same sim card in a different RUT241 and it works.
Nothing interesting to see in /tmp/mobile/mobifd.log
Both RUT241 the same hardware and
both Firmware version RUT2M_R_00.07.15
I’d like to view the logs of the troublesome router. I’ve sent you a form to fill out so we can continue our conversation in private, to avoid accidentally leaking any sensitive information. In the Ticket ID field, simply enter the thread’s number, which is 14309.
