Question

I saw any post about Reachability but people doesn’t really give the exact answer to the problem.
In my application I use the Reachability code from apple and in my appDelegate I use this:

-(BOOL)checkInternet {

Reachability *reachability = [Reachability reachabilityWithHostName:@"www.google.com"];

NetworkStatus internetStatus = [reachability currentReachabilityStatus];
BOOL internet;

if ((internetStatus != ReachableViaWiFi) && (internetStatus != ReachableViaWWAN)) {
    internet = NO;
}else {
    internet = YES;
}
return internet;    
}

So the problem is even if I have an internet connection, this code telling me that I don’t have one.
Does anyone know what to do to make this working?

Thanks,

You should probably be using +[Reachability reachabilityForInternetConnection] rather than reachability for a particular name (unless of course that’s what you actually need).

There could be all manner of reasons that a particular server might not be reachable while you still have a working internet connection, after all.

This is what I do:

BOOL hasInet;
Reachability *connectionMonitor = [Reachability reachabilityForInternetConnection];
[[NSNotificationCenter defaultCenter]
    addObserver: self
    selector: @selector(inetAvailabilityChanged:)
    name:  kReachabilityChangedNotification
    object: connectionMonitor];

hasInet = [connectionMonitor currentReachabilityStatus] != NotReachable;

and then

-(void)inetAvailabilityChanged:(NSNotification *)notice {
    Reachability *r = (Reachability *)[notice object];
    hasInet = [r currentReachabilityStatus] != NotReachable;
}

which works nicely for me.
