Hi. To all of you who purchased the NEW Airport Extreme 6th Gen 802.11ac Using the Airport Extreme 5th gen and older as a router have had a limited Routing Performance. http://www.smallnetbuilder.com/wire...rport-extreme-gen-5-reviewed?showall=&start=1 On the 5th Gen Airport the Throughput of the Airport have been limitied to 430 Mbps on the gigabit ports .. For example say you use your airport as a router and connect to is with CABLE ONLY. (Cable from modem to Airport and cable from Airport to all the Macs) You will never exeed more then 430 Mbps on the local LAN due to the INTERNAL SPEED LIMITATION. This means that even if the Airport have gigabit ports and you might have a gigabit ISP or gigabit LAN you will never exceed speed of more then the internal speed of the airport . (For some reason Apple thought it was not nessesary to have internal gigabit speed of the Airport) For some of us we use the airport as a router and connect multiply macs to it with Ethernet Cat 6 cables and we never exceed speed more then the the internal speed of the Airport. I´m using a App called "Speedy Net" to test the Network performance Mac - Mac and at WORK I get almost 800-900 Mbps with my rMBP using Ethernet and using a corporate router. At home with my Airport 5th Gen never more then 400 Mbps using ethernet cables only .. So my Question is have the INTERNAL speed of the new Airport Extreme 802.11ac finaly reached gigabit speed ? Is the Throughput finaly faster ?
