Hr24 connection issues - DirecTV

I have 2 HR-24 receivers and a DIRECTV wireless cinema kit to connect to the internet. I have gone though the setup and have both receivers connected to the internet. However, the receivers will disconnect from the network periodIcally. The whole home continues to work flawlessly.

When I get the notice that the receiver has lost connection, it won't let me immediately reconnect. I usually have to wait 5-10 min, it will then reconnect. Cinema kit is only about 15 feet from the router with good signal. I don't have any connection issues on any other devices. The connection issues have persisted through two different Motorola and the other Netgear.

This question, "Hr24 connection issues," is about DirecTV channels, programming, equipment, and sports.
