After initial success with my High-Speed Internet Gateway, my unit stopped working after only a couple weeks. Many calls later and multiple hours on hold, I received a second unit which appeared to work properly but would not connect to the internet (even with a strong signal). It seemed as if it was an addressing issue. I suggested to tech support to “clear out” my first unit’s info and start fresh with second unit. They could only advise me to uninstall and reinstall my app. 🙄
I then received a third unit which exhibited the same issue as unit #2. This time, however, I had a more competent tech support person who re-addressed my “imsi” number in their system. Unit #3 began working nominally.
I throw this out there in case you find similar circumstances with subsequent installations. I looked here and did not find anything similar.
