Huawei 3372 LTE stick not working in SFOS 20.0.2 MR-2-Build378

Steven Lew

Hi everyone,

I am using a Huawei 3372 LTE stick on my SG-125 with SFOS for a couple years now. It is configured in DHCP mode as a failover WAN connection when the main connection goes down. Up until now this worked as intended but after upgrading the firmware to SFOS 20.0.2 MR-2-Build378 it does not connect anymore. The error message appearing on connection attempt is:

"The modem doesn t support the configured network adapter method (DHCP)."

Also when on Build 378 i noticed that the dongle is recognized as usb0 additionally to WWAN1 which is not the case on the older version.

I just downgraded the firmware back to SFOS 20.0.1 MR-1-Build342 to confirm and it is working again.

Please tell me if you need more info.

    Hi All,

    We confirm we are seeing this issue too, its taken us a little to narrow it down and confirm our suspicions. 

    We have been using Huawei E3772 sticks configured to present as 12D1:1506 or 12D1:14FE for many years across our fleet of XG (various Gen's) and XGS (Gen 1) units.

    We recently started to upgrade some customers through the V20 MR's and some to 20.0.2 and in that process, we believed we lost access to the dongles on upgrade so paused our rollout.

    We had a XGS108 arrive today, and it confirmed our suspicions straight out of the box.

    XGS108 arrived with SFOS 20.0.1 MR-1-Build342
    We connected our stick and it worked
    Upgraded to 20.0.2 MR-2-Build378 and it failed.
    We also upgraded to SFOS 21, and it is still failed.

    We now have this confirmed this on an XGS87, XGS116 and XGS108.

    We have an order open with out disti for 50 XGS, but have it on hold until this issues resolved.  Our experience with the SOPHOS modules have been disappointing for both reception and SOPHOS support (our mobile carriers not listed as supported, so they just close the cases!), so we don’t particularly want to transition to the 5G modules as our dongles have been very reliable to date.

    I haven’t yet logged it with support, but will do so on Monday.
