I'm having a minor issue that I failed to notice before release: by the time a player has a score they'd like to submit to the online rankings the WiFi has turned off since it wasn't being used, then they end up getting an error. I didn't notice since I did most of the testing with the device plugged into the computer, and WiFi doesn't turn off in that situation.

What's the proper way to handle this? I've considered either a more descriptive error message, finding some way to turn WiFi back on when it's needed, or occasionally polling WiFi to keep it alive.
