    Has anyone else encountered this problem or know a solution?

    Every once in a while, my ATV (original) loses its connection to my Mac. This occurs every one to four months. After a lot of trial and error I discovered that when this happens it is because the ATV had an IP address not on my wireless network, although the ATV said it was still connected to my wireless network.

    When this happens, I reconnect to my network and enter my network password, and everything is fine for another month or more.

    Has anyone else had this experience? I didn't see anything in the forums about this.

    Does anyone know why this happens? Or, more importantly, does anyone know how to prevent it from happening again?

    I had the exact same issue you did for a long time. Very annoying.

    My problem ended up being the following: The issue stems from the router having a DHCP lease time of 24 hours. So, once I logged in on the Apple TV, 24 hours later, the lease expired, and the Apple TV could not log in anymore. I set the lease time to be 300 days. I haven't had that problem since, but I'll probably have it on day 301. :)

    All other networking devices worked fine before, so there is something wrong with how the Apple TV does this.

    It also might work if you set up a static IP address to the Apple TV, so it doesn't have to 'forget' it's lease over and over again.

    A better solution would be to go into your router, in the DHCP section and enter the MAC address for the AppleTV and assign it to a fixed IP address. That way, even when the IP address expires, it would be assigned the same IP address again. Any server type device (server, AppleTV, Printer, etc...) should have a "fixed" IP address (either by hard coding it in the device, or via the DHCP assigning method).
