UPDATE:
I have replaced one of the modems inside with an R11e-LTE6 I stashed somewhere and it immediately started working properly. I hope anyone that buys FG621-EA to make sure they work with their carrier before getting one.
I have an LtAP LTE6 running dual FG621-EA modems. LTE is connected and I am getting an IP address + a default from the carrier. However, I am not able to ping anything. There is absolutely no internet connectivity at all. This is happening on both modems. The same SIM card works fine in a phone as well as in an older LtAP LTE6 kit that has two R11e-LTE6 modems. Something is very wrong with these new modems. Does anyone have a clue what could be going on or any fixes? Because this has put a pause on my plans completely.
