Hi @goldenmonkey, welcome to the community and thanks for posting. I'm really sorry to see you're experiencing problems with your broadband connection, I've moved your post to the broadband section of the community as this will be the best place to get help with this.
Can you post your Home Hub router stats and we'll be happy take a look? You'll get them by entering 192.168.1.254 in your browser, if you have a home hub 5 please go to troubleshooting then helpdesk and if its a Smart Hub go to advanced settings then technical log information.
I'd also recommend you do a quiet line test? - dial 17070 option 2 it should be silent
