Ok, so I have an iPhone 5s. For some reason I'm not able to get close to the download speed I'm paying for which is 50 . On my iphone and iPad highest I reach is 25. My time capsule is set up on my iMac on my first floor. I use an express to extend the network so it works on my second floor. I consistently get 25 mpbs, I just don't know why I can't get closer to what I'm paying for. Not sure if I'm doing something wrong,. Please help!
