I have no internet where i live so I used mywi over USB from my phone to my MacBook. I then enabled internet sharing to airport so that the MacBook would create a network the atv could recognize. After i enabled home sharing i turned off mywi. For a couple weeks everything worked fine with home sharing. Just a few minutes ago, i was streaming from laptop to atv and it suddenly stopped and atv said it lost connection. I checked settings and it still showed it connected to the network but it would freeze at loading my library when i tried to do it again. I ended up having to just reset it. How can i assure this won't happen again
