I'm interested in optimizing my current coaxial splitter setup that was primarily done by Comcast on one of their service calls.
During the first stage the coaxial cable from the cable provider is split (1000mhz, -3.5db on both outputs) (black splitter on left of image). 1/2 goes to an return amplifier (white box center of image) and then an 8 port splitter (far right of image; unknown specs) which provides all the TV's in the house with a signal, and the other 1/2 goes directly to a cable modem.
I am curious as to how I can possibly optimize this setup for better all around performance. The signal on the TV's is fine and not grainy, but I sometimes experience Internet outages for a minute or so in the afternoon.
Would it be beneficial for me to replace the splitter in the first stage? Or to boost the signal for the modem with a separate amplifier? Do you see any issues in my current setup?
