the 2.4ghz and 5ghz not the problem here, 5ghz support wireless N too
the 5ghz support higher bandwidth at shorter distance only, but at last u have to refer to the wifi N and AC
and what the picture show i also a theory speed only not real life benchmark usage speed

Last weekend I went to Singapore.
Using my iPhone 6S
Connect to a 2.4Ghz SSID (DLink DIR-868L router)
Did a Speedtest and got this result.
[attachmentid=8481731]

Then connect to a 5Ghz SSID (on the same router)
Did a Speedtest and got this result.
[attachmentid=8481732]

How come I can get a faster speed on the 5Ghz connection?

that's why anyone who has internet connection 20mbps above needs 5Ghz WiFi AC instead of slow 2.4Ghz N

2,4Ghz N only can achieve high speed when signal is above 80%,

also why many ppl complaint unifi 30 or above dont have actual package speed especially on wifi

tm always give lasap d-link wireless N 2.4Ghz router

if internet over 100Mbps, u must have Gigabit LAN over cables or Wifi AC/AD 5Ghz standard

* and take note Wireless N also got 5Ghz but doesnt mean it is faster than 2.4Ghz N, same IMO

Thank you for all your inputs.
Looks like it is the limitation of the iPhone6S on 2.4Ghz wifi connection.
On the iphone 5, eventhough it can detect the 5Ghz SSID and can connect to it, it still has a speed of the 2.4Ghz wifi connection.

yep thats 5Ghz N and it still has same speed of 2.4Ghz N, just different frequency that can prevent being overlapped by other electronic device frequencies /neighbour 2.4 Wifi nearby

iphone 5 only support single stream (1x1:1). Iphone 6&7 are dual stream (2x2:2)

Bear in mind that the wifi standard used for iphone 5 is only standard n, and it does not support MIMO technology.
And also the processor of the phone matters too. If you compare iPhone 5s and iPhone 5c, which share the similar if not same wifi configuration and controller chip, running wifi Speedtest on 5Ghz wifi network on both phones and you will realise iPhone 5s can score slightly better than 5c.

Thats normal... Its like comparing 2 lane highway vs 5lane highway...

For sure wider 5 lane highway u get more chance to drive at higher speed...


But 5lane highway also shorter.. so u cannot reach far compared to 2 lane highway that can cover longer distance...

This is the easiest example to compare between 2.4ghz wifi and 5ghz wifi bandwidth speed...
