I have a ltAP Mini RB921R-2nD-LTm. If I upgrade the firmware beyond 6.42.10 the lte interface disappears and is no longer addressable.
I have tried this up and down the versions available. The firmware-upgrade command for OTAP upgrading the lte firmware was not introduced till 6.44 so I cannot attempt to upgrade the lte individually.
Can anyone help me to get the lte interface back up at a higher firmware version?
