I came across this post from another user having issues with their 5GHz band.
I am experiencing two issues.
5GHz stops working
Random internet drops outs and slow speeds
My situation is slightly different in that after rebooting the Archer VR1600v router, both 2.4 and 5.0 GHz are showing. However after a few minutes, hours or days (it varies), the band is still being broadcasted. When I try to connect to the 5.0 GHz,
(a) using my iPhone - it will ask for a password which after inputting, it doesn't allow you to connect saying password is wrong (even though it is right)
(b) using my iMac - it will try to connect and give me an error unable to connect.
I am technically minded and have done the following:
rebooted my modem - after rebooting, the 5GHz works again for a undefined period before not working again.
rebooted my devices
rebooted NBN device
unplugged cordless phone when testing
changed network cables
reset the modem and reconfigured
tested using LAN and WiFi connected devices.
my house had the LAN rewired when I had issues with TPG ADSL.
In addition to this 5 GHz issue, I often get drop outs and slow speed dips throughout the day that cuts out my internet.
Your help is appreciated.

TPG customised the firmware of the supplied TP-Link Archer VR1600v modem/router for security purposes this caused the modem's back up configuration and some of it's feature is no longer available.
