I have a Time Capsule and I have a/b/g/n enabled. I just purchased an iPhone 5 and my wife has the iPhone 4S. I noticed that my speeds in wifi seemed slow. I decided to run some speed test using speedtest.net app. The results have all been the same. The iPhone 4S gets 7.0-8.5 MBS down on my 10MB connection while the iPhone 5 only gets 1.0-2.0MBS. I have tried several different servers and the results are still the same. I verified that both of the phones are connected the same way. Anyone else have the same issue?
