I have Virgin Media home braodband thats high speed. All worked fine but i noticed there was one site i couldnt load some images on. Then i noticed another and also we are having issues authenticating to icloud.
I have numerous Apple devices, eg imac, macbook, iphone etc and all are the same.
If i use my 4G iphone as the as internet connection then i can authenticate to icloud and load the images.
I've restarted the router etc, changed my DNS on local machine to use 22.214.171.124, fluched cache but still the same.
Looking for ways to trouble shoot please
