I just purchase 3 WF-803M and connected the first one to my NetGear (C7000) Cable/Modem; the second is connect to a Xfinity port in my house which is connected to a Xfinity device for viewing TV, I disconnect the coax cable and connect it the MoCA device TV coax input then I connected the MoCA port to another coax cable and the other end to my Xfinity device - the error I see on my TV is that there is not connection please check.
I review my MoCA device connections and everything looks good but same results. -- HELP!!!!!!
You likely have an Xfinity X1 TV device, which also uses MoCA ... and the RF pass-through port of the MoCA adapter doesn't pass MoCA frequencies. You'll need to use a MoCA 2.x-compatible 2-way splitter to connect both the MoCA adapter and X1 device to your coax (and cap the unused pass-through port on the MoCA adapter w/ a 75-ohm terminator).
