Ok, had the app working fine - could control all seven rcvrs from my iPad, as well as download from my Nomad. TWC is going to push us up to 300MBPS, but you need a DOCSIS 6.0 compliant Cable Modem. Decided it was time to toss the leased CM, so I bought the Netgear C3700-100NAS. It includes WiFi, and Cnet loved it. Two Ethernet ports out. At the same time, my Swim died, and DTV comes out to fix it (after I installed the new CM). When the system comes back up, the iPad says "out of home" and can't see the Nomad. Make sure the receivers are connected to the net - even put the IP addresses in the box on the iPad - "invalid receiver". So here's where I think the problem is: all wireless is coming out of the cable modem router. One of the two CM ports goes to the Ooma box - the other to a Linksys small office router. The four ports on this router go to a eight port powered switch (for the Cat 6 in every bedroom), to the family room equipment cabinet (powered switch there for the AV rcvr, Roku, Apple TV, and a DVR), and to the DTV internet pickup (#4 was the wireless network access point now made redundant). So I am thinking the Linksys router is the problem - it could be assigning IP addresses downstream of the WiFi cable modem router, and therefore the iPad can't "see" the DTV devices. If I am right, then is the solution to replace the Linksys router with a gigabit powered switch? Should that fix the problem? And if it isn't, does anyone have any ideas? Thanks in advance.
