Spark 1570 (non LTE model) - problem with external modem (HUAWEI E3372)

[ks87]

Hello,

I've just bought an supported Huawei E3372 modem which is working on modem mode (non Hilink) and it looks like CP is losing a connection to this modem every 1 minute. After a while connection is working, but after another minute the modem becomes unavailable again.

Modem was tested under Windows11 machine and is working very stable, so this problem is not a modem-related.

Does anyone from the community experienced similiar problem?

Firmware version: R81.10

Have you opened a TAC case here?
