I’d be surprised if it needed an antenna. The GameFrame is literally 10 feet from the router in the same room. Nothing but air between them. Even the same height from the ground.
I noticed that the back cover for the GameFrame is darkened where the Photon rests against it. Maybe it got too hot and was going bad? Not sure. Maybe I should cut an opening in the cover where the board touches it.
Anyway I currently have the GameFrame sitting on my desk with no back cover right now and waiting to see if it stops responding to commands sent. Currently still working correctly but it will be few days before I am convinced this fixed it.
