i have a 5th generation 802.11n dual band airport. The last of the flat editions. I am interested in getting a 6th generation 802.11ac model. Will the newer unit have a longer signal range? Currently when I go to the front porch, I can browse web pages and text and read email on my phone, tablet or laptop, but any streaming video on YouTube or other really doesn't work. It is approx 50-60ft from the broadcast point to the router. I currently have a CenturyLink Fiber modem coming into my basement (100Gbps) and a 4th or 5th gen n base station connected to it. This unit does not broadcast. It has 3 LAN ports in use (DirecTV, in house Ethernet, 2nd in house Ethernet). The 2nd runs up to the master bedroom where it feeds into a Slingbox (non wifi model). The first runs to our main tv room where my broadcast 5th gen is creating the home network. The new tall Airport would go here.
