Here are some specifics on my set up. Apple Time Capsule downstairs, with an Apple Airport Exterme set up in WiFi extend mode upstairs. Hoppers and Joeys connected to the network via a HIC (Hopper Internet Connector). The ethernet from the HIC connects to the Time Capsule via HomePlug. Broadband and MoCa on all Hoppers and Joeys indicate full green. Have from day one. When trying to use the Sling apps, they will start out with a strong signal, then drop out. Example, on my home Wifi they start out at around 3XXX Kbps, then will drop to exactly 632 Kbps. Then bounce between 0-632 Kbps. Now, with my MBP sitting next to my iPad with a 0-632 Kbps black screen, I can view my Hoppers content through Dish Online, and maintain a strong signal with no drop outs at all. So, i'm thinking my Wifi network is functioning well enough to support what i'm trying to do.
