Code to do this is here.

You can call:

    self.remoteHostStatus           = [[Reachability sharedReachability] remoteHostStatus];
    self.internetConnectionStatus   = [[Reachability sharedReachability] internetConnectionStatus];
    self.localWiFiConnectionStatus  = [[Reachability sharedReachability] localWiFiConnectionStatus];
