If the network at the stadium during the game was down, then it would have affected many people and not just these few Microsoft tablet. It's sort of like a power outage since they are all on Wifi.
My bet is they had to reboot their Microsoft Surfaces to get them to reconnect to the WiFi. Problem solved! So it was a hardware issue (the Microsoft Tablets) and NOT a network issue.
Again if it's a network, then it affects everyone and not just a few tablets.
okay you really should stop talking when you don’t have a clue.
