I got a new Macbook Pro and have had the same problem with the exclamation point through the airport icon. On numerous phone calls to Apple I have been told it is a router problem. I have not yet had a chance to go out and buy a new router to see if this is correct. It is very annoying not to be able to get the internet.

It seems that it only happens with wireless networks that require a password, which unfortunately my home network does. I often hit this problem after my MacBook Pro wakes from sleep. Sometimes it takes a couple of goes. Hi James, That's exactly the point! You shouldn't have to do that at all. See if deleting and recreating the network, or making a new Location, helps your laptop connect automatically. It seems that the local network doesn't recognize the DNS.

  5. Since I can't change the router, I have created a 'location' that is as 'plain Jane' as possible with no DNS specified. That seems to work every time. Another possibility is a corrupted keychain key. Open Keychain Utility and delete the key for the network that the Mac is failing to connect to automatically. You'll have to reconnect to the network as if it were one you've never used before, but after that hopefully your Mac will remember it and join automatically. In the section "Recreate your preferred network", I am told "Select the Wi-Fi connection in the list of network services on the left.

    So Wi-Fi appears in the list of network services on the left of the Network pane? And what happens when you select it? I've gone through 3 hubs so far Anker and Buffalo and when I connect them to one of the 2 available USB 3 ports on my MBP retina inch late model it often causes the wi-fi to stop. Apparently there are interferences with the 2. I have achieved better luck using the 5 GHz band.

    My current hub, a Plugable, is better, but I have experienced the outage once. In all cases with the hub, a restart was not needed. Just an unmounting of the connected drives and hub. Then wi-fi returned to normal. Plugable is being very cooperative and sending me out a new hub with the latest chipset and firmware which they say works around this problem.

    It seems to be an Apple issue they need to address.

    Why is explanation mark on Wifi symbol

    I have two MacBook Airs, one older one running The old one always reconnects as it should. The new one has this sleep problem to such an extent that most of the time I don't sleep the machine at all using a combination of Caffeine and NoSleep. Most people mention sleep, but I notice that the screen switch-off not the screensaver also induces wifi-amnesia.

    The list of available wifi networks is empty at that stage: I've found nothing in the discussion pages, but it should be said that notwithstanding Google and the like, it is becoming more and more difficul to weed out the irrelevant stuff in internet searches. Presumably the NSA has better search algorithms, but I don't think we don't have access to those.
