Infinity checker accuracy??

I am due to get BT Infinity installed on Tuesday and the checker says 22.5Mbps download
5.6Mbps upload.

However I know I am 2.7Km from my green cabinet, in the country, so would assume I would not be able to get it at all.

Is the checker accurate or only a stab in the dark??

Some people say it's conservative and some say it's accurate.

For me it's totally wrong. Suggests 40.6Mbit but never got more than 27Mbit over the last 2 years. Know my attenuation to the cabinet is 25dB so it'll never go that fast.

If your line length is accurate, the checker might be right for you.

I can confirm that the Infinity speed checker is completely inaccurate..

Estimated speed from checker 22.5M.
Actual speed after engineer visit 0M, he couldn't even get the equipment to sync, even tried the 80M profile, still nothing at my house.

Back to ADSL, 2.7M, at least it only costs £6 a month..

How far would you estimate you are from the cabinet?

No sync at all suggests may a jumper issue at the cabinet. Did the engineer leave to go check the cabinet side of things?

I can follow my line exactly from the cabinet as it is all overground.
By car it is exactly 2.7km from the cabinet.

He did go back to the cabinet and checked again.

He tried to run a Line Quality Test afterwards but could't get that to work either.

*EDIT* Just got a text to say they are coming out again on the 9th May

The 22Meg is a bit optimistic if line length is 2700 metres. I'd be suggesting about 12 to 15 Meg

What the engineer should be able to do is connect to your telephone line at the old cabinet, and check whether the VDSL2 is visible at the old green cabinet, if yes then the wiring is correct, and most likely a long line issue.

If at the old cabinet they can get no signal, then it is a provisioning issue rather than line issue

Thanks for the info, Is there anything I can do now to get them to come back, they do appear to have made a new appointment for the 9th May but not sure what that means.

I am just over 2KM with some aluminum between me and the cab and I get 19 down and 1 up.

Checker originally stated 8 down and 0.5 up but over the months the checker has changed to 14.3 down and 1 up

Ask provider what the appointment on the 9th is going to be

Rang and they said the engineer has reported a fault on the network yesterday so they are coming out to try again on the 9th.
