    We have a brand new Airport Extreme (Simultaneous Dual-Band II). This replaced an older model that worked perfectly until it died. This new machine will drop the connection for all connected devices, when any new machine connects to the network. Connected devices include MacBook Pros, iPads and iPhones. It happens about 50% of the time a device connects.

    When it does happen, our network name just disappears from the list of available networks. If you try and connect manually, you get a timeout. Left to its own devices, it will eventually reconnect after a few minutes and apart from the annoying reconnection delay, it loses the VPN connection we all have on the laptops. Frustrating to say the least.

    I have updated the firmware and of course restarted the Airport many times. Is this fixable or should I return the unit for replacement? Thanks for any suggestions.

    Has it always done this?

    If not, you might try to reset to factory settings.

    Also, is there anything in the logs? It keeps reasonably decent logs, I'd suspect something will be in there.

    Thanks for your reply smithrh. Yes it has always done this. I have pasted todays log below. Perhaps the Disassociated and Deauthenticating bits mean something? Can you spot anything that is awry?

    Nothing obvious from those logs.

    Certainly this isn't appropriate behavior.

    You might call Apple if you haven't already - something is amiss. Not sure if it's expiring all of the DHCP addresses all at once, or the wifi radio is somehow being shut down momentarily.

    Does this happen with hardwired connections as well? If it does then it would tend to point a finger to either DHCP or even some of the encryption/authentication. If not then it points a finger to the radio portion.

    You might also take a look at your Console logs on your laptops and see if anything pops up when you lose the connection.

    I know you said you've restarted many times but try a true factory reset and see what happens?

    1. Unplug the AirPort Base Station or Time Capsule from power.

    2. Press and hold the reset button with a pen or pencil, then plug the AirPort Base Station or Time Capsule back in while continuing to hold the button until you see the light (LED) flash rapidly. This should happen after a few seconds.

    3. Release the button. This will factory default reset the AirPort Base Station or Time Capsule.

    Thanks for the suggestion jenzjen and apologies for not reporting back sooner. I did try the full reset exactly as you instructed and wanted to give it some time to see if the bad old behavior recurred. Unfortunately it did, not at first but eventually after a few days, gradually getting back to how it was when I first reported it.

    Our network name just disappears from the list and all the computers drop off. You know it has happened because you hear the iChat connection sound on each computer as they come back on line. It might even be tolerable were it not for the fact that the VPN connections are all lost at the same time. I guess it is time to take it back to Apple.

    Thanks again for everyone's help.

    Try one more thing. For the time being move the router to be out in the open like on the floor near the center of the room and see if you still get the dropouts.
