I am trying to get rid of cable. I own a Moto E4 (or is it 4e). I run it as a hotspot. I can stream Netflix on my TV without issue. I can play my on-line game without issue. But I cannot do both at the same time.

Is the solution to either:

A - Get a new phone with eight cores and tons of memory?
B - Get a bridge and hook the phone up to my current router?

Thanks in advance,
Dean
