We've just purchased an RBSXTR for trialing; first one in the country as far as I'm aware, and our supplier is trying to replicate this issue.
We have a test SIM with a local LTE provider that works well in an SXT-LTE. However, when putting that same SIM into the RBSXTR with the same config, the lte1 interface disappears after about one minute. A minute later the interface appears again, and the cycle repeats itself. I presume that once it gets connectivity, the interface instantly disappears. The unit shipped with firmware v6.42.1, and I upgraded to v6.42.5 (both ROS and firmware). Same issue on both versions. I've also made sure I'm using the latest WinBox (v3.16).
Is anyone else seeing this issue? I know it's a new product (I think US release was ~1 month ago), but I'm sure a few would've been deployed by now.
EDIT: I've managed to get this working with a SIM from one of the other local carriers, but unfortunately that carrier won't work for us in the long run. Still seems like a strange issue though.
