How do I get better speeds on my home wifi network?
Setup includes; Comcast cable modem, Airport Extreme, Macbook running 10.8.2, AppleTV3, 2 iPhone 4Ss, and 1 iPad 1.
At this point, When I do a speedtest on Comcast's page I get 20 to 25 mbps, but via Speedtest app on iPhone I get only 3 to 5mbps. I have read and tried a few things like changing DNS to OpenDNs and such, but nothing makes much difference. Am I misunderstanding the rlationship between these numbers? Is the Airport Extreme only capable of under 5mbps, or is it the iPhone? Is there a better way to test?
