Hi team, I've researched and read similar cases on community forum and I believe the router is not compatible with my USB LTE modem (Huawei E3372-325).

  - LTE modem works when connected to a PC,

  - router works when connected to internet via Ethernet cable,

  - router's USB port led blinks when LTE modem is inserted to router's USB port (modem's led is red),

  - router recognizes a different USB mass storage drive when inserted (so the port itself works),

  - I've upgraded firm ware to the latest available.

I am based in Slovakia and use SIM card from Orange. Are you please able to help or is it recommended to exchange the modem for a different one? If modem change is recommended, can you please suggest compatible types? Thank you very much!
