I am planning on adding MoCA to my Mother’s house to decrease the reliance on wifi for streaming. She has cable internet (but not cable TV) and in an upstairs room there is a (I presume) signal amplifier plugged into an outlet and it has a coax cable running into the coax wall jack.

I have been reading a lot about MoCA today and I saw something that said that amplifiers had to be inline before the MoCA system. Is this correct? The amp she has is on the end of one branch of the coax system.

I don’t mind purchasing a different amplifier if necessary, but locating it outside the house would be difficult. What are my options?
