If you're looking for a way to use Gears to get the network connection status directly, there isn't a way to do that at the moment -- at least, not that I know of. I think it's pretty much left up to the developers to figure out how they want to detect network connection. If the browser has a way to detect network status from the OS (or whatever), and there's a way to figure out from the browser whether the device is online or offline, that would probably work, but I'm not sure if there are any browsers that have that capability.
