I live in an apartment and only have one cable outlet. Before, I had the outlet split between my TV and my cable modem… I was getting 29-30 dB SNR ratings for the cable modem and it functioned okay.
Recently I’ve had to add another TV (with another splitter), and the cable modem is getting 25-26 dB SNR ratings and is losing signal a few times a day.
Is there some way I can keep both TVs and boost the cable modem’s signal? An inline booster or something?
Another, related question:
If I have one cable line, and split it, and have outbound lines A and B… and then I take B and split it and now have outbound lines A, B, C, and D, with C and D off the B wire - does device A (split once) have more power than device C and D (split twice)? The cable tech told me all that matters would be the net drain and they’d all suffer the same no matter which way you split them - is this true?
