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're probably gonna get better answers if you add some more details. You could post your implementation code for example. Also try to do some debugging: some `NSLog`s at least. `Reachability` should of course work on devices, too. I use it many apps. — Rok Jarc, Nov 06 '12 at 08:36
as i said, it works fine in simulator!!... i have edited my question to add the code. — footyapps27, Nov 06 '12 at 08:40
You might just have to clean the project, delete the app from device... Anyway: you'd really be better off using observer - one of best examples can be found [here](http://stackoverflow.com/a/3597085/653513) — Rok Jarc, Nov 06 '12 at 09:05

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;

}

i have just added my code to check for internet.. it should do the same. — footyapps27, Nov 06 '12 at 08:46
Apply my answer and check the NSlogs. It should say the exact reason,why there is an connection — Shamsudheen TK, Nov 06 '12 at 08:48

In My case the following code snippet is working perfectly with iOS 5. Here i am checking internet connectivity with WIFI.

- (NSString *)stringFromStatus:(NetworkStatus ) status {
NSString *string;
switch(status) {
    case NotReachable:
        string = @"Not Reachable";
        break;
    case ReachableViaWiFi:
        string = @"Reachable via WiFi";
        break;
    case ReachableViaWWAN:
        string = @"Reachable via WWAN";
        break;
    default:
        string = @"Unknown";
        break;
}
return string;

}

------------------------ now with following line of code you can check.

 Reachability *reach =[Reachability reachabilityForLocalWiFi] ;
NetworkStatus status = [reach currentReachabilityStatus];
NSLog(@"%@", [self stringFromStatus: status]);

if ([[self stringFromStatus: status] isEqualToString: @"Not Reachable"]) 
{
    UIAlertView *alert = [[UIAlertView alloc]
                          initWithTitle:@"Connection Failure !"
                          message:@"Your Device is not Connected to any active WIFI Connection."
                          delegate:self
                          cancelButtonTitle:@"OK"
                          otherButtonTitles:nil];
    [alert show];
}
else
{ //connected to internet.

}
