I have fifth generation Airport Extreme. Everything worked well until recently, when my ISP increased the speed of my connection from 60 to 100 Mb/s. My Airport doesn't seem to be able to receive the full speed. The maximum download speed I get on speedtest.net is 85 mb/s. I have tried resetting both modem and router, but it's still the same. When I connect the modem directly to my computer, the full speed is there, but not via Airport. My Airport settings seem to be in order, and I don't know what else to do. Do you have any tips as in how to get the full 100mb/s speed via Airport?
