I have FIOS internet and TV, with the house wired with coax, no Cat5 cable. at one coax endpoint I have the Actiontec router supplied by Verizon, with a roku XD connected to the ethernet port. Works great. There is no verizon set-top box at this tv.
At another coax endpoint I have an actiontec ECB2200 MoCA adapter, with the coax connect to "coax network" and another length of coax connecting from the adapter's "STB" to the verizon set top box. the ethernet port on the adapter connects to a Roku XD/S.
Problem: The Roku initially shows "connected with ethernet", then when it actually tries to get any data it shows failed. If you run the setup for wired it steps through and eventually fails to connect the internet. Doesn't matter if the STB is on or off. BUT if you unplug the coax between the adapter and the STB, it works.
AND if I jack the ethernet into my laptop instead of the Roku (wireless off), the internet is fine even with the STB connected to the MoCA adapter. Clearly the Roku is deficient in some way in getting an ip.
Ideas anyone? The wifi is ok, but I want to get the wired connection going.
