I just installed my new Airport Time Capsule. I read that it might improve my WiFi speeds but didn't expect this. I usually saw speeds in the 40-45Mbps range when doing tests on my iPhone 5 and iPad 4. Just did 8 tests and saw speeds that ranged from 71 Mbps to 90.73 Mbps for downloads and 10-11 Mbps for uploads (that didn't change. These things fly now!!!
