Re: Swapped to BT - Terrible Speed #2

You don't seem to understand how the network works.

You're right in that the line, cabinets and exchanges are all Openreach (not BT) responsibility and all data to the exchange follows the same path. There is no problem here, the fibre links back to the exchange usually have at least 2.5Gb/s capacity, with the potential of a LOT more. This is not where the bottle neck is.


As I've said, Sky and a few other providers such as TalkTalk use a different backhaul from the exchange.

When the fibre connection from the cabinet gets to the exchange, the data is handed over to the relevant layer 2 switch for the onward connection. BT use a BT Wholesale backhaul, as do the likes of PlusNet. Sky and TalkTalk, amongst other providers don't, so their customers are routed differently once they hit the layer 2 switch in the exchange.

BT as in your ISP wouldn't know about it, least of all the sales advisors.


The ranges on the DSL checker are relevant to sync speed, not throughput.

I agree that if the issue can't be resolved within a reasonable time frame, then you should be free to leave without penalty.


Have you considered trying a third party router to rule out the home hub?

Re: Swapped to BT - Terrible Speed #2

See what the results are with that. If the issue resolves itself with a reboot, it's very very, very unlikely to be network congestion.
