Reachability working on simulator but not on device - iphone

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.

Answer 1

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;
}

Answer 2

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.
}
