Connect Box 3 won’t broadcast 5 GHz on the main SSID, but Guest Wi-Fi works

Hi,

I’m hoping someone has seen this before because I’ve never encountered anything quite like it.

I have a Sunrise Connect Box 3 on a new fibre connection.

The problem is that I cannot get the main Wi-Fi network to operate correctly on 5 GHz. It appears to work only on 2.4 GHz.

What’s strange is that the Guest Wi-Fi can broadcast on both 2.4 GHz and 5 GHz without any problem.

I’ve tried enabling/disabling the radios, applying settings multiple times and rebooting the router, but the behaviour remains the same.

So the hardware is clearly capable of transmitting on 5 GHz, because the Guest network does so successfully. It just seems that the main SSID refuses to.

Has anyone seen this before?

Connect Box 3
Sunrise fibre
Latest firmware (as supplied by Sunrise)
Main SSID appears limited to 2.4 GHz
Guest SSID broadcasts on both 2.4 GHz and 5 GHz

I’d be interested to know whether this is a firmware bug or whether there’s some obscure setting I’ve missed.

I’m reasonably confident this isn’t simply a configuration mistake.

Thanks.

hello Boimbeengai35

It looks like your Connect Box has some hiccups.

To change your WiFi-settings successfully you might have to reset your Connect Box. Keep in mind all settings will be lost but you should be able to activate the 5GHz WiFi afterwards.

A full reset was my next step. I’ve got a conference call in a few mins, I’ll look at it again when I’m through.

indeed, a full reset did enable 5 ghz
