I've had the same issues. This seems to come up every few months, where the connection just keeps dropping out and we find the router box with the wifi light green. We will have a week or so where the connection just keeps dropping out like this, the wifi gets really rubbish, yet checking local information there are apparently no issues. We just have to keep rebooting the router. I suspect there are local issues, but the information isn't so great as it seems to resolve itself after a while. We've got so much connected through ethernet cables now (used all the available slots in the back of the router). I just don't have the time or energy for the long call to confirm you've done everything you can do and it works okay now but you know you're just going to end up back in the same cycle.
We are on the max broadband package as well which I was advised to boost previously but in reality made no difference whatsoever. The only benefit was getting a phone sim with unlimited data so we can at least rely on that for a hotspot when someone has to work at home.
Considering getting BT lines installed when current deal tie in is over.
Are the issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables? If you don't know, can you check to help diagnose whether it is just a wifi issue or it could be network connection related?
Is it a Hub3 - and what is the Hubs base power light showing/doing when this happens?
