When the Cyber Monday discounts hit, I finally bit the bullet and dropped $150 on an AirPort Extreme router. Boy am I glad I did. My iOS devices are performing much better in every way that involves wifi. My previous router was a D-Link DIR-655. This is a good N router. But I had a number of issues that even multiple attempts at changing router settings could not fix: I could never get AirPlay to perform as good as I thought it should. For example, if I streamed a 1080p video clip shot with my iPhone to my Apple TV, there was a LONG wait to cache enough video before the Apple TV would start playing it. I'm talking 30 second wait to stream a 10 second clip. I could not get iTunes wifi sync to work reliably. It would work when I first plugged in the iPhone, activated the setting, then unplugged it. But subsequent attempts could not find the PC over the network to enable sync. Often playing a Youtube video on the phone would run into issues streaming the clip in at a reasonable speed. ALL these things are massively better with the AirPort Extreme. 1080p clips of any length start playing through AirPlay almost instantly and the caching stays ahead so there's no pausing. Airplay mirroring keeps up with the phone display well enough that I can play a fast-pace flying game while only looking at my TV. Youtube works great. Speedtest pings are low and speeds maxed out to match my DSL speed, anywhere in my two story house. And after a one day test it looks like Wifi syncing is solid too. I never imagined spending $150 on a router, but once again Apple has proved to me that their products are worth the money. I've invested enough in Apple devices to make this one final investment to make everything I already own work better.
