Just tell him you don't want a separate coax run from your splitter to your router. He/she will need to get in your attic to replace the splitter with a green label splitter and maybe install a band stop filter to your lnb if its not a green label lnb. If the power inserter is a problem you could move it to one of your other receivers. Just remember you need to swap the cables at the main splitter so that the power inserter is connected to the DC passing connection on the splitter. To be safe just move it during the install.
