I transferred to broadband full fibre 900mbs yesterday. Speed is fine. Quite a few websites aren't loading images however and I can't use my Amazon firestick anymore (cinema hd isn't working at all since yesterday). The images are just greyed out. I've tried changing my DNS, switched it to 5ghz, tried it without the firewall, tried resetting my router. If I try the same websites on my mobile data they work absolutely fine.
