Hello everyone. I've been searching long and hard for an answer with no success. I'm hoping someone here can help me out. A few weeks ago I upgraded my speed on my ISP from 30Mbps down and 4Mbps Up to 50Mbps down and 8Mbps up. I used to have a WRT54G Linskys router which gave me great speeds on my ipads, iphone, Apple TV and both windows based computers. The other day I switched the Linskys out for an new AirPort Extreme. I Set it up and the speeds on all my devices were constant around 35 down and 8 up. I left the default settings on the AirPort Extreme. Then a few days ago I set up the security for my router, WPA2- Personal. Checked the speeds and my computers, ipads are running great but now my iphones are doing constantly for the last 3 days 1Mbps down and 8Mpbs up. So last night I tuned off my security and than the iphone was back to normal speeds. I'm pretty much confused now. Any ideas? Seems like the security setting are doing something here
