Hello guys, I'm using a brand-new Airport Extreme 5th gen BS. I installed it in my apartment on top of an elevated cabinet, and I'm getting low throughput when on the 5GHz network. AFAIK 5GHz is supposed to be the innovative ultra-fast one, where it is little to no interference. However, as you can see on the map I have drawn, my throughput is really not that fast and it decreases dramatically when I'm far from the BS. I'm wondering if my unit is faulty? And sometimes I'm getting even better throughput on the 2.4GHz network in the "remote" rooms, even though it is supposed to be crowded and generally bad. Could you offer advice on what is wrong here? Is it normal? P.S. All the walls in my apt are concrete. P.P.S. All the measurements were taken using iperf to my desktop which is connected to the AEBS with UTP.
