New to BT and having issues with my network. Since swapping to BT having difficulty using Chromecasts, office PC won't open certain websites, hardwired thru a couple network switches, but the laptop will open them fine. Various devices will struggle to get an internet connection once connected to wifi. I have various IP cameras connected via tp-link switches and power line extensions. Already had a replacement hub sent and made a little improvement but still having above issues. Any ideas please?
