I have 2 IPTV boxes running, and I just connect 1 wf-803 before my extender with the ethernet cable to one of the iptv box but I need to connect the second one. I try an ethernet spliter out from the extender but I can't get internet. It's possible from the coax outlet put a splitter and connect another wf-803?
Thanks.
Yes, you can use a RF splitter to connect IPTV box and MoCA adapter.
But we are still unclear about your network diagram.
Could you draw a simple diagram?
