I have cable and cable internet in my new apartment. The cable comes in to the water-heater closet from the roof and comes out an outlet in the wall of the closet, but there is a 4-way splitter in use before the cable gets to the outlet. It's not used to split the signal at all; the other three output connectors are empty.
Since I added cable internet service (and used a 2-way splitter after the outlet), my tv cable signal is a little fuzzy on some channels; and I was wondering if the cable splitter in the closet is to blame. Could I buy a simple connector to replace the 4-way splitter and see an improvement; or would it be the same, since the splitter isn't actually splitting the signal?
