I got this modem with a three months contract in Italy by TIM. After one year, I upgraded to Lisa B11, then to Nordic B11 and finally to OpenWRT 24.10.0.
Sometimes it occurs I need to restart wwan0 interface as internet connection freezes.
Output of the query on the modem:
Manufacturer: ZTE CORPORATION
Model: MF286DMODULE
Revision: BD_TELIAMF286DV1.0.0B02
SVN: 01
IMEI:
+GCAP: +CGSM
Is it something someone is experiencing? Is there any hint?
Thanks in advance.
Update modem firmware.
See https://openwrt.org/toh/zte/mf286d#internal_modem
are saying I should go back to nordic B12 and then reinstall OpenWRT?
No. If you want to keep using OpenWrt then you only need to update modem firmware from BD_TELIAMF286DV1.0.0B02 to BD_TELIAMF286DV1.0.0B12
Ok, understood. I'll look for firmware & instructions. I'll be back in case of need.
I found a repository with many files named imageB0XtoB0Y and the procedure how to go.
I understand I need to follow the schema starting from B02.
Is there something which requires particular care?
Just follow the order.

Great! Multiple steps to get the result but the process was really smooth.
I'll monitor the behaviour in the next days to confirm the problem has gone. Thanks
