For about a week or two we started having problems with our LTE LHG antennas using R11e-4G modems, namely receiving NW Detach Commands for no apparent reasons. (See picture attached for the received commands)
Would someone know the possible cause of this ?
Could it be the LHG antennas fault or is it the eNB it connects to since the command uses NW, not ME, so referring to the Network not the specific antenna as I understand it ?
