I have a strange situation I would appreciate your advice on. I have an older apple airport extreme N router (the flat square one) and using my IPhone 6SPlus with the speedtest app (Ookla) I regularly get a download speed of 80 or 81 mbps and upload seed o f12 to 12.20 mbps. I subscribe to the faster internet speed from Xfinity (Blast-up to 75mbps). I thought that I might receive faster signal if I upgraded to a new AC wireless router. I tried a newer router and I am receiving the same speeds that I did with the N router. Am I doing something wrong? I spend a hour on the phone with tech support from the new router and we made a lot of changes, retested and kept getting the same results. I was hopeful that I would see an increase in download speed with the newer AC wireless router.
