Yi 1080p connection issues

Hi, been using Yi cameras for a few years now with no issues. But I’ve recently had fibre installed and a new talk talk wi-fi hub 2 set up… I’ve successfully paired both cameras and they load up on my phone… but after a day or 2 they no longer work. I’m now getting the network unavailable please check your network settings (-3003) error??

What do I need to do? Never had any issues with my old router.

When I setup again is it a case of making sure 5ghz is off until I’ve paired up successfully again?

And also I’ve seen something said about making sure UDP packets are enabled?

Any help appreciated…
