Sierra had released t-mobile firmware for the EM7511, and would like to use it but peplink has not updated firmware in such a long time. What triggers them to update firmware? i manually pulled the modem out and applied the firmware, but upon re-installation, not all information is posted in the GUI. I use sprint, and understand that the firmware for them will likely not be updated again, and i am unable to get 2x CA upload, but i can with the t-mobile firmware on b41 when using the sprint apn.
looks like it was just signal, i connected to my panel antenna, all is well.
