I'm new to the forum, and I have a question about how fibre broadband services work.
I know that compared to some parts of the country, where we live (north London) has very good fibre broadband provision. We currently have BT Infinity Broadband (FTTC), and the speeds are fine when it works, but it frequently simply stops working. We have had frequent visits from BT engineers, after which the broadband has worked for a few days and then disappeared again. There are also recurring problems with the landline.
I'd like to understand what would actually change if we changed fibre broadband provider. To what extent do other providers rely on BT equipment at the exchange, or on BT fibre to the cabinet in the street, or on BT copper wire from the cabinet to my home?
Thanks for your help,
