Answer 1

Hope this helps you to network in Wifi mode only:

Utils.h

 #import 
 @interface Utils : NSObject

 +(BOOL)isNetworkAvailable;

 @end

utils.m

 + (BOOL)isNetworkAvailable
{
      CFNetDiagnosticRef dReference;
      dReference = CFNetDiagnosticCreateWithURL (NULL, (__bridge CFURLRef)[NSURL URLWithString:@"www.apple.com"]);

      CFNetDiagnosticStatus status;
      status = CFNetDiagnosticCopyNetworkStatusPassively (dReference, NULL);

      CFRelease (dReference);

      if ( status == kCFNetDiagnosticConnectionUp )
      {
          NSLog (@"Connection is Available");
          return YES;
      }
      else
      {
          NSLog (@"Connection is down");
          return NO;
      }
    }

//Now use this in required class

- (IBAction)MemberSubmitAction:(id)sender {
   if([Utils isNetworkAvailable] ==YES){

      NSlog(@"Network Connection available");
   }

 }
