Hub 5Ghz status DOWN

[guerilla]

Hi TT Team,

I've very recently been plagued with an issue to the 5Ghz signal from my TT Hub.

The 5Ghz Wi-Fi Status is currently showing as DOWN.

When I first spotted the issue earlier today, status was UP yet I could not see nor connect to 5Ghz.

2.4Ghz Wi-Fi connected and wired ethernet connected devices seem to be running fine.

I have tried:

Connecting to the Hub with dIfferent devices,

BRoadcasting 2.4 and 5Ghz on different SSID's,

Changing 5Ghz SSID's,

Changing 5Ghz channels,

Rebooting the router

EDIT to add the following:
Talk Talk Hub version SG4K100174

Is this something you could look into, please? Perhaps a firmware fix?

My home phone number is in my profile.

Kind regards, and thank you in advance

Hi guerilla,

Glad to hear it's working again

Thanks @KeithFrench 

The 5Ghz issue seemed to resolve itself somehow without the need for a factory reset!??

I'll temporarily rename the 5Ghz SSID to ensure I'm on 2.4Ghz next time, instead of disabling it!

With the router turned on, press & hold the recessed reset button on the rear for about 10 seconds. 

The bug is current, there is no workaround as yet.

Thank you, @KeithFrench 

Yes I did disable 5Gjz manually, yesterday.

I got a new IP Camera and it only works on 2.4Ghz so I temporarily disabled 5Ghz whilst I set it up.

How do I perform a reset, please?

Any way TT can push an update so I don't have to do this, though?

Did you disable the 5GHz band initially? There is a bug in this firmware version that if you do, the only way to get it back is to perform a factory default on the router.
