The whole amp thing. Yeah...I'm going to tackle that after the install, I think. I'd like to see how things work out first, and if performance could still use improving, try an amp.
I've been looking at
this simple 4 output amp, which might work instead of a splitter. There's also this
bi-directional amp that I could put on just the modem's line. I have to see what happens next month, when hopfully I have the $$ to buy all this stuff.
