Cutting the cable, lets talk options and media setups

You can't use a wifi router from one of the internet lines and split the rest into OTA signal?

There seems to be conflicting information on whether you can have a satellite and cable internet feed going over the same coax. Some say yes, use a diplexer. Others say no.

Or are you suggesting something else? I could try using just one of the output lines from the current splitter for internet. Maybe I'll test that to see if I can get the set up I want.
