In my home network, my Apple TV, iPad, and Macbook Air all have the same problem. The WiFi network works fine, but after about an hour or less, the Wifi stops working. Things just hang when I try to things like open a webpage or ping yahoo.com. The WiFi signal icon is still on, however. The fix for me is to turn off my wireless on my Apple device and turn it back on again.

But this is annoying. How can I fix this? I'm using a Zonet Wifi router with WPA2 on. My ASUS Ubuntu netbook has no problems staying on the WiFi network.

For what it's worth, I have the exact same problem, mostly when streaming from my iPod/iPhone/MBP to my AppleTV: it'll be working fine and then suddenly AppleTV can't find the devices until I cycle the iDevice's wifi connection. Resetting the router has had no long-lasting effect for me. I read somewhere that it has to do with WPA2 encryption, which I also use. Most likely, it's the router or the router's implementation of WPA2. Make sure your router's firmware is up-to-date. –  Donnie C Apr 29 '11 at 15:57
    
I have the same problem, it's not my router - and it's not all my devices- IT ONLY HAPPENS when I turn on APPLE TV and try to do AIRPLAY. Apple TV works fine, UNTIL I push the airplay button. Then all wifi connections shut off. IDEAS? I did not have the problem 6 weeks ago. NEW updates, now nothing works as it should –  user45321 Mar 16 '13 at 23:11

I agree that since your problem occurs over many devices it is unlikely to be a problem with the Apple devices. I appreciate your point about the Ubuntu device still appearing to work, but it still seems more likely to be a router problem (it could be for example the router is producing multiple errors that the Apple software is catching).

I'd suggest a hard reset of the router as Step 1 (before you do so however make sure you know ALL your current router settings, not just your name and password. I take a screenshot of each setting page)

Most routers have a Reset button you have to press with a paperclip.

Power off the router for several minutes, then apply power and do an immediate reset.

Networking problems can be a little bit of hit and miss when troubleshooting. My first guess is that this is not related to your wireless router, but to the way the Apple devices are renewing their IP address from the router (I presume that you are using standard settings and are handing dynamic IP addresses via DHCP). I say this because you mention that your Ubuntu laptop has no issues and because all devices continue to show an active Wi-Fi indicator.

My recommendation would be to first make sure that there are no IP conflicts between your devices. First, turn off the Apple TV, iPad and all Apple devices except for the MacBook Air. Then use the MacBook Air as you normally would to find out if you still loose your connection to the Internet after an hour or so. If you don't loose your connection to the Internet, then turn on the next Apple device and pay close attention to who is the first one to loose connectivity and when.

I have seen this problem happen to me whenever I use the my Clear Wi-Fi hotspot when I am on-the-go. I will get messages from the MacBook (not the iPhone, although I know they both are having the same problem) telling me that the IP was lost because another device is using it. This problem does not occur when I am at home using the Wi-Fi network served by an Apple AirPort Express rotuer.

I highly recommend the AirPort. However, if you want to keep using your existing router and you confirm the IP conflicts I suspect of on the paragraphs above, then I suggest configuring your router to not hand out IP's with DHCP, but rather to have your devices use static IP's and see if that helps. It is a little bit of a pain to do so, but it may be the only way your devices can co-exist.

Hope these thoughts help. Good luck.

Since it affects multiple devices, I suspect it's a problem with your router. On the official Apple discussion board someone had a similar problem with a Zonet router and the issue resolved itself when they replaced it. Fortunately, routers aren't that expensive - the extremely solid and reliable WRT54GL is available on Newegg for $50 and won't cause any problems for your Apple devices.
