What speed will my not too great line get?

So i have paid £5 extra a month to uncap my line. I can withdraw from the new contract within 30 days if my line doesn't increase over 40meg. My ISP Sky have said it will hit 50meg max. Here are my stats i know the guys on here are a lot smarter.

Broadband Link Downstream Upstream
Connection Speed 39999 kbps 9999 kbps
Line Attenuation 21.7 dB 0.0 dB
Noise Margin 10.3 dB 6.6 dB

Ignore the 0.0db on line attenuation upstream it's a common Sky hub issue that it fails to show it. Nothing to do with my line.

What estimate does www.dslchecker.bt.com give for your line?

Hi, It seems since my line is with Sky it won't work accept with the address checker or postcode checker which it warns is less accurate.

address checker says.


WBC FTTC 18x2 Sim Availability
High Low High Low
VDSL Range A (Clean) 47.9 35 10 6.8 32.4 Available -- -- Yes
VDSL Range B (Impacted) 38.5 22.2 9 5 16.5 Available -- -- Yes

Postcode checker doesn't even mention fibre however i am already using 40meg Fibre and it has been around this area a while now.

There is literally 0 point in upgrading, stay on the 40/10 package, not worth the extra money for 7Mbps more.

Not to me this house is very heavy usage any speed increase will help. If it increases by just 3-4meg or something i will switch back before the 30 days. If it increases to 47 or above I'll take it. Before i got fibre my line used to hang around 7-8meg on ADSL. Lived with that for years.

That's why the postcode checker is useless. Many postcodes are served by a few cabinets located around it and also covering neighbouring codes. That checker only reports the first in the database.

if you enter only the postcode into the address option and press "Submit" or whatever, you will get a dropdown of all addresses in the postcode.

If you click on each in turn you will see the cabinet numbers (on the line above the table) are not all the same and some like you will have VDSL2 available and others not. Usually but not always, all those on a common cabinet will be enabled. But sometimes a address on that cabinet will be too far from it.

That is a great answer for that checker but doesn't really help my question. Am i likely to hit close to 50 say 47+ with my stats or will i end up having to downgrade within the 30 days back to standard 40meg?

Well those are the estimates you have: 47.9-50 Mbps

All you can do is try it and see.

Thanks well heres for hoping to get 47+

Given your attenuation you will certainly get a few Mbps, but how many only time will tell. Bear in mind that higher speeds result in higher error rates, which could cause DLM to mess about a bit.
