I just got done setting up my iPhone 5(as new, not restore). I was trying to download my music from iTunes when it seemed to be taking forever. I cancelled the downloads and then kept testing the WiFi in various other ways. Just loading the app store, my iPhone 4 will load anything faster than my iPhone 5 right now. I've rebooted the router and tried multiple devices and have narrowed the problem down to the WiFi in the iPhone 5. I've also tried using different bands, 2.4 and 5 both produce the same outcome. I launched speedtest.net app about 2 minutes ago and hit begin test. Its still "finding the closest server". I have also tried the reset network settings. Still the same issue. Any suggestions? I would really suck if my new iPhone was already broken... Update: For those that don't want to read the entire thread. After quite a bit of playing with the phone/WiFi, I found that WPA2 was causing packet loss of over 80%! I activated the guest network on my Time Capsule and left it unsecured. I had no issues with WiFi on the unsecured network. I then went to the Apple store and had the phone exchanged for another new one. I restored the phone on my unsecured guest network and then placed it on the WPA2 secured network. After more testing, I am able to confirm that the replacement has solved my issue. I now have no packet loss running on a WPA2 network.
