I have a 100mbps connection through Charter Communications as my home internet provider. I live in a 2 bedroom apt totalling 1,250 sqft. I have a MBP that gets 100mbps hardwired from modem to comp, hardwired from router to MBP, or using on Wifi. All of which I am in the computer room within a 3 foot radius of the router. If I step about 10-12ft away from the router my speed will drop (using wifi) to around 75-80mbps. The further I go, the more it drops. I also have two iPhone 5's connected to the router, an iPad 2, Apple TV, Samsung Smart TV, and my DirecTV Genie box. When checking the speed on my iPhone 5 I am pulling around 30 mbps, the iPad 2 stays around 18-20mbps. The interesting thing is that my iPhone will sometimes pick up around 80mbps, but it's very rare. The speed tests using the iPhone 5 (speedtest.net) app jumps all around with speed tests. Can someone help me out. I know I have a steady internet connection from Charter, so I feel it has something to do with my Airport Extreme router. I would very much appreciate it! Thank you!!
