What if our lobby Wi-Fi is bad?

The scanner checks each ticket over the phone's internet connection, so cell data works when the lobby Wi-Fi does not. Tell volunteers to turn Wi-Fi off if the lobby network is slow.

If the phone loses its connection, the scanner shows Offline. Scans will not check until the Wi-Fi is back. There is no offline mode yet, so scans wait until the phone is back online.

For a known dead zone, test the door link in that spot before the show, and keep a printed list from Download attendees (CSV) as a backup.
