MOCA and Airport extreme

MOCA send tv and ethernet signals around the. House via cable wiring.. just needs a two piece system.. one to cather the origiknal feed ro send along the canling and another on the other wnd to unscramble that signal.. seems simple BUT the modem connection to the MOCA is unclear to. E. Main canle feed is in my. Ase,dnt snd so is the modem.. but ai ran canle from modem across ceiling, up theough closet, to floor 3 to directly feed into Airport Extreme .. then I ran ethnet cable back down theough same closet to a 5port switch in basement.. where I distributed the signal via cat 5 canli g ip into two rooms and acroos ceiling for basement office...

still have week signal in ends of main floor, so used two Irport express to extend. Etwork.. worki g but not as well as hoped dor.. loss of signal frequent. MOCA is blazi g fast but need to figure out just how to attach the first device to the basement modem.. to get TV/inter dt i. First floor bedroom using second Moca device .. gotta be doing so ething wromg, and ACTIONTEC ONLY SENDS CRYPTIC MESSAGES WHEN i ask their hel, as if so eone sends canned prepared responses! Its free jelp but not really jelpful!
