I am seeing some instability with latest modem firmware now (16121.1034.00.01.01.05)
lte1 disappears from interfaces list after 5-10 mins and it's simply gone.
In Resources however, there's still a Fibocom FG621-EA visible.
Only resolution: reboot
Observed on 7.13.3 and 7.13.4
When turning on lte logging, it looks like the modem is trying and trying (sending AT commands) but nothing happens.
But it could also be the famous 'modem boot loop' observed in the past, where people were told to RMA the box.
(I can't believe that - but read below)
I tried to downgrade modem firmware to 04 but it seems impossible.
File from here: https://upgrade.mikrotik.com/firmware/F ... 1.04/image, it says "firmware successfully flashed" but it simply stays on 05, even after reboot.
Also tried various reset commands like
"AT+reset" --> command not supported
"AT+RSTSET" --> command not supported
The only command which works is "AT+CFUN=15" but it looks like this is just a soft reset (restart) of the modem.
Somehow it is all not working like described here https://help.mikrotik.com/docs/display/ROS/LTE
Netinstalled to 7.13.4 but of course this didn't help - I just wanted to make sure and have a 'clean' device.
Default config - same issues.
I was reading on the forum somewhere that somebody solved this problem by simply upgrading to the latest BETA.
Gave it a try and upgraded 7.13.4 to 7.14.10 and voilà - indeed all okay, even overnight now.
I can't see anything in the changelogs 7.13.4 --> 7.14.10 that would (to my understanding) explain a different behavior here...
But I am willing to troubleshoot as it's just a lab device.
To start off with - how to downgrade the modem firmware from local file?
Knowledge of the local file process is there - but box doesn't take a lower version.
I wanted to re-flash 05 but it looks like a logic link like https://upgrade.mikrotik.com/firmware/F ... 1.05/image doesn't work, there's no 05 image.
Anyone?
