Drop in profile speed.

Hi There!

 

I'm on the 40/10 BT product and most of the time my profile is around 38Mbps down and 10Mbps up. Over the past week I have checked my profile using the BT speed tested and have found that it has dropped down to 31Mbps and stays there. I have powered off the HH3 and the Fibre modem for around 10 mins and when I check a while later the profile is stuck at 31Mbps.

A while ago I ran the BT speed estimation and it said that with the 80/20 product I should have an expected speed of around 72Mbps down and 20Mbps up. Now when I run the BT speed estimation is says that my line should have a maximum speed of 35Mbps !

What has caused this to drop ?

There has been no change to my system of phone line.

Re: Drop in profile speed.

for your profile to drop there might be errors on your line (i'm assuming your outside the settling in period)

 

If these are temporary the DLM will slowly return your profile

but, if not, the profile may stay there.

 

Were there any issues lately / powercuts or cabinet maintenance?

Do you currently hear noise on your telephone line?

 

I'd suggest asking the mods to look and tell if they can see any errors.

Re: Drop in profile speed.

Many Thanks Alan63,

 

Yes I've had BT Infinity since the end of Feb this year.

As far as I know there have not been any issues / power cuts or cabinet maintenance - haven't seen any BT OR van around.

Background noise on the telephone is the same as before.

How do I get the mods to have a look for any errors ?

Line noise can be outside the audible range and can easily reduce an IP profile

Re: Drop in profile speed.

Have been emailed by BT and have sent a reply so I'm waiting for them to investigate further...

Re: Drop in profile speed.

if there is a line fault they'll be able to see. Also the DLM will increase profile (but it is slow).

 

mine took a knock in september but has now gone back to what it was before.

 

Also don't go switching on/off the modem/router too many times in quick succession - it can be interpreted as fault by DLM

Re: Drop in profile speed.

Email yesterday from BT to say that they've tested my line and found a line fault between my home and the cabinet.

BT OR engineer arrived at my house just after 9am today.

Did some testing on my line and the cabinet. Got my profile reset.

Did a speed test, but profile still at 31.36Mbps.

I'll wait to see if it changes.Smiley Indifferent

Re: Drop in profile speed.

BT speed appears to be stuck at 31.36Mbps. Contacted BT Mods, they have ran a line test and there is still a fault on the line Smiley Sad They have arranged for another engineer visit.

Let's see if this can be fixed !

Hi dsh63

 

Fingers crossed you don't have any aluminium cabling between you and your cabinet. That can be very deleterious to VDSL signalling. I speak from experience.
