Hi folks I have been trying to figure out why my download speeds are not as fast as I expect. I have recently installed a Cisco 2702 in place of my Cisco 1041 AP. I have the AP plugged into a Cisco 1921 router via a non Cisco dumb 10/100/1000 switch. My internet connection speed is ~75Mbit down & ~8Mbit up (att Uverse). I have tested my download speeds from a wired computer and get very good results in the range of 75Mbit down and 8Mbit up, thats great. However when I test from my Iphone 6 or Ipad Air 2 My speeds seem to max out at ~40Mbit down and 8Mbit up. Obviously the upload speeds are as expected but not the download. Now I have switched over to my Toshiba laptop Tecra Z40 with Intel AC 7260 wifi nic and I get better results but still not port speed of my Internet connection somewhere in the range of ~60Mbit down 8Mbit up. I have tested with the 2.4ghz radio in a shut down state to make sure that my devices are indeed on the 5ghz radio and no changes. Can someone please explain to me what I have done wrong on my configuration or point me in the right direction to have my wireless devices download at something closer to my expected Internet speed? I am going to include my radio configuration below, if I need to include more I will be happy to paste it in just not sure what all is useful.
Thanks in advance!

If you are getting 60Mbps in wireless (from 75Mbps internet link), that is really good throughput. Since wireless is half duplex media & lot of overhead (control & mgmt frames) your throughput will be limited.
You cannot get wired equivalent throughput in wireless.
