Reachability not work

Question

I use this method to check connection:

- (BOOL)networkConnection {
    return [[Reachability reachabilityWithHostName:@"http://medsolutions.ru"] currentReachabilityStatus];
}

Its all work in simulator, and on iPhone 6, but not work with iPhone 4S. I mean, block:

if (!([self networkConnection] == NotReachable)){

Always return false, which means that there is no connection, but actually it is connected via wi-fi.

Answer 1

I am checking rechability in one of my projects something like,

 if ([[Reachability reachabilityForInternetConnection]currentReachabilityStatus]==NotReachable)
    {
        NSLog(@"not available");
    }
 else{   
         NSLog(@"available");
    }

if you want to check particular host then,

  if ([[Reachability reachabilityWithHostName:@"http://medsolutions.ru"]currentReachabilityStatus] == NotReachable) {

     NSLog(@"not available");
}
else{   
     NSLog(@"available");
}

Hope this will help :)
