Hi there, I have a networking question I can't figure out yet! Here is the deal/situation: I live in a 3 story house which has a Airport Extreme(june 2013 model) on the first floor and an Airport Express (june 2012, 2nd gen model) on the third floor. These two are connected with eachother by a CAT6E ethernet Cable. The cable should be able to provide 1GBps over 100meters so that can't be the bottleneck. Our ISP provides 300Mbits which I can confirm by forcing my macbook to connect to the AExtreme on the 1st floor and do a speedtest. According to Apple/Mactracker the AExtreme has: Wireless Data Rate Up to 1.3 Gbps and the AExpress Wireless Data Rate Up to 300 Mbps. Even though all hardware provides the right max data numbers. I'm not able to get a faster signal than 90-100Mbits on the top floor by WiFi (I checked via Airport Utility that my Macbook was connected to the Express) Also my iPad Air2 is not able to get numbers above 90-100 range. (Macbook is a Retina Mid 2014 model.) Can anyone explain my why this happens (Express Max numbers are wrong/fake/very optimistic?) and what to do to crank up the speed on the top floor to 300Mbits ? Cheers.
