Suggestion: Some sort of extra wifi watchdog
To deal with those situations where wifi simply ceases to function for no apparent reason I was just wondering whether some sort of belt and braces test so Xbee can tell if it is connected to the rest of the world would be useful rather than relying solely on the disconnection event to trigger action.
Maybe periodically pinging the gateway while wifi is expected to be up to verify connection and resetting the wifi if it is unreachable.
