wi-fi on iphone6 plus keeps connecting to my 2.4ghz network and not my 5ghz network

Hi all I'm a bit puzzled as my iPhone and also my iPad and my macbook air only seem to connect to my 2.4ghz wireless network and not the 5ghz network i'm also running? They do connect if i select the 5ghz network manually, I thought the idea of the dual channel on theses devices was supposed to pick the best network to connect to. I have run a wireless noise test and on the 2.4ghz channel there is a lot of noise but hardly any on the 5ghz channel so to me it makes sense that the devices should automatically connect to the 5ghz channel but none of them do? Does anyone have any ideas

I have the two networks running on different routers set on different channels. I need the 2.4ghz channel for devices that cannot connect to the 5ghz one

It's quite obvious when connected to 2.4ghz as all devices run clearly slower

No problems are being caused it's just bugging the heck outta me

iPhone 5, iOS 9.3.2

iOS devices will connect to the band that you chose manually. They will not switch automatically unless the signal on one of them gets very low, low enough to approach disconnecting. If both bands are on your list of networks and enabled, an auto switch will only occur at 1 star or less.

Below is a User Tip about Wi-Fi issues. Maybe one of them will help.

1) Perform a Forced Restart: Hold down the Home and Wake/Sleep buttons at the same time for about 15-20 seconds until the Apple logo appears. Allow device to restart.

2) Reset Network Settings: Settings > General > Reset > Reset Network Settings. Rejoin the Network again.

3) Reboot Router/Modem: Unplug from power for 2 minutes and plug again. Update Router Firmware (check manufacturer’s support website for a newer FW). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (20 MHz recommended for the 2.4 band).

4) Change to Google's DNS: Settings > Wi-Fi > Click on the Network, Delete all numbers under DNS and enter 8.8.8.8 or alternatively 8.8.4.4

5) Disable device prioritization on the router if this feature is available. Also disable any VPN apps and test Wi-Fi again.

6) Determine if other Wi-Fi devices on network are working well (other iOS devices, Macs, PCs).

7) Try device at another Network, i.e., neighbors’, public coffee house, etc.

8) Backup and Restore the Device using iTunes (ask for additional for details if desired).

9) Go to an Apple Store for hardware evaluation.
