I have >200 RB953GS-5HnT. I instaled 1 modem LTE on first port and R11e-2PHnD on second port. Within 4 weeks of installation the port deaf. Not seeing any cards on port when is R11. It port J405 next to buzzer.
This problem is now on 4 RB so I think this is probably a bigger problem. You are met with something like this?
