My tablo buffers every few minutes when trying to watch our local channel 2. The broadcast antenna is 12 miles away and I placed the factory antenna in a window that faces the broadcast tower, it's a clear line of sight, I can see it on a clear day.

Any idea how to fix this? Do I need a better antenna or need to put it in my attic? It seems like optimal conditions for reception.

I've rebooted the unit and the software is up to date.
