I have dish but don’t have the hopper and just want to do Ethernet over coax. Could I connect my router to a HIC then to coax and in another room connect a HIC to coax then to my computer for Ethernet? Basically just want to skip connecting to the hopper part as I don’t have the hopper, I just have a pretty basic dish dvr and it works fine for me.I don't have dish any more and I'm still using HIC's to extend my network. They work great. Just put an hic where the hopper was in the diagram and use the rj45 port to an Ethernet switch.
