5GHZ Wifi cannot be enabled on AC800S

I have a new AC800s with Optus (AU), all connected a running fine.

However, I want to enable the 5GHz band (run 5 & 2.4GHz together.

On the modem, if I press WiFi on the home screen I can choose to turn on 5GHZ, but the slider at the top right won't move to the enable position.

If I login to the modem via the Netgear Mobile app I can select 2.4&5GHz but that does not enable it on the modem.

Can anyone offer advice?

Also, how do I find the firmware version on the AC800s?

Regards

    Hi emmsee

     

    Welcome to NETGEAR Community! 

     

    Kindly access the router ui, go to Settings > More. You should be able to see firmware version. Kindly check if there is an update available.

    Hi emmsee ,

     

    By default the Optus AC800S is set to broadcast both 2.4G and 5G at the same time.  If you have a device that is capable of connecting to 5G access points then you will need to search for the _5G SSID being broadcasted.  For example if the 2.4G SSID is OPT-7D94 then the 5G SSID should be OPT-7D94_5G and uses the same password as the 2.4G.
