We have sky fibre for over a year now. All has been fine. However, in the last week or so its become very unreliable. Apps on iphone are slow to load, or not opening at all. Websites on laptops etc are slow to load and lagging or just timing out - teams has become a nightmare. Where our hub is hasn't changed, we haven't done anything differently. I've run multiple speed tests, rebooted the hub etc and it isn't fixed. I've checked devices and when not on wifi they are all working fine - there is clearly an issue with either our hub or network. I've used mysky to check the broadband and wifi and it's all saying it's fine which it clearly isnt. Please help.
