Fibre 1 appears to be capped at 40mb?

Hi,

I know there seems to be a lot of people asking the same question and I've read some of the previous answers but I'm non the wiser!

Essentially I believe that I should be getting around 52mb download but my router seems to be capped at 40mb.

Part of the reason I pay the "BT premium" is that their standard fibre is capped at 55mb rather than the usual 40mb. Is there a chance I'm on a legacy profile or is it just DLM?

For background I've just moved house and ported my package over to my new address. The new address was initially a nest of extension cables so have recently had a new master socket installed. This new installation has improved my max attainable speed to 52mb from 30mb but my sync rate is exactly 40mb.

Is there any way of checking what profile I'm on? I'm not sure if the installation engineer requested a DLM reset when he installed the new socket.

have you been having connection problems with hub dropping connection or maybe manual resets trying to improve speed or maybe both

Thanks for your reply.

In answer to your question - no I've had no issues but the new line has only been in 24 hours 😂

I suppose I was just expecting my actual speed to improve at the same time as my "max available" speed. It did but only up to a new value of 40mb 🤷‍♂️

Is there any way to check if I am on a 40mb profile?

The more I think about it the more it seems like I'm being capped.

According to the openreach stats the previous max download speed before I had the master socket moved was 29mb/s but now I'm syncing at 40mb/s. So the performance has improved but I'm not getting all that the line appears to be capable of.

Apologies if there is something else in play that I don't understand.

@kevinpaulwest I'm sorry to see you're having problems with your broadband speed. It does appear to be stuck at 40Mb and we'll be happy to get that looked into.
