Hello, 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!!!!!! Thank you,😀
