Reachability working on simulator but not on device

Question

In my project I am using Reachability class provided by Apple. When there is no internet connection, I am displaying an alert message. Everything is working fine, when I test it on the simulator, but when am running it on iPad, the alert message is not shown when there is no internet.

I am running the code on iOS 5.0.

Any help would be appreciated.

EDIT:

-(BOOL)isInternetConnectionPresent{

Reachability *objReachability = [Reachability reachabilityForInternetConnection];    
NetworkStatus internetStatus = [objReachability currentReachabilityStatus];

if(internetStatus != NotReachable)
{
    return YES;
}


   return NO;
}

UPDATE:

Used NSLog to debug. Seems there was some problem with WWAN, even when there was no SIM card. Restarted the iPad & switched OFF & ON the Wi Fi again. Now it works fine. Thanks for the help guys.

You have to check all the NetworkStatus and Cross Check the device Wifi Connection status again

Example:

// to check if, wifi connected properly in current device.
- (BOOL)networkCheck {

    Reachability *wifiReach = [Reachability reachabilityForInternetConnection];
    NetworkStatus netStatus = [wifiReach currentReachabilityStatus];

    switch (netStatus)
    {
        case NotReachable:
        {
            NSLog(@"NETWORKCHECK: Not Connected");          
            return NO;
            break;
        }
        case ReachableViaWWAN:
        {
            NSLog(@"NETWORKCHECK: Connected Via WWAN");
            return NO;
            break;
        }
        case ReachableViaWiFi:
        {
            NSLog(@"NETWORKCHECK: Connected Via WiFi");
            return YES;
            break;
        } 
    }
    return false;

}
