I have read on this forum about people who are able to use their Joeys wirelessly. I believe I read that the Joey needs to be "connected" to the internet. How do I accomplish this? I have one Hopper (with an external Sling adapter) and one Joey. I have internet to the Hopper with a USB wi-fi adapter plugged into the Hopper. Would I need an additional wi-fi adapter connected to the Joey? (Yes, I realize this is unsupported.)
