Chateau 5G AX - lte disconnections - error: MAX_ACTIVATED_CONTEXTS

RouterOS General
1

Hi,

I have a new Chateau 5G AX (S53UG+M-5HaxD2HaxD) running version 7.17beta4 (testing) and LTE firmware RG502QEAAAR11A06M4G (Queltec RG502Q-EA)
I noticed that it has 9 LTE disconnections in last 4 days.
I enabled a watchdog to reboot the router after 1 min of connectivity lost to 8.8.8.8 and activated the logs to disk.
Here are the related logs from the last disconnection, just before the watchdog reboot:

My problem solved after upgrade to the latest beta modem firmware RG502QEAAAR13A03M4G_02.004.02.004

This first started happening to me on a similar device since yesterday, twice during my presence, so I simply toggled the LTE interface both times. which seems to fix it immediately. But according to the logs, it happened more, in 3 hour intervals. At least the interface seems to recover by itself after 2 minutes of error spam.
I’ve been using the Chateau 5G R16 (D53G-5HacD2HnD) for over 2 years now. The only thing I changed recently is update the router from 7.17.x to 7.18.2, and that was several days (if not a few weeks) before the first occurrence of this problem.

  • LTE Firmware Version: EG12EAPAR01A15M4G_01.203.01.203 (latest)
  • RouterOS Version: 7.18.2 (latest stable)

Full logs attached. Any clues what could this be caused by?

Is there any solution to this problem? I am also getting MAX_ACTIVATED_CONTEXTS error.
