All I can repeat is that by changing the router to Mode 1 my disc has worked perfectly every since
I've never changed the mode from Mode 1. The system just doesn't seem to cope with 5-6 complete wifi discs. Even ones that have been purchased separately.
firmware is as far as I'm aware, up-to-date and I've also done a factory reset 3 times. I've also had 2 broadband engineers out and 2 Home Tech Experts.
All of which can't fathom out what the problem is.
Today we're meant to be receiving a new Smart Hub 2. Time is getting on now and I honestly don't think its on its way.
