Adduxi · Answer

Downstream power is too low, it should be above -6&nbsp; &nbsp;Preferred range is -6 to +10&nbsp; &nbsp; If you have an attenuator fitted, try removing it and check the power levels again.&nbsp; Otherwise a VM tech will need to adjust those.&nbsp;

AlanOHara · Answer

Thanks for the reply, I'll remove the attenuator and check again

AlanOHara · Answer

Removed the attenuator, here are the logs:
