ADSL2+ to VDSL has slowed my speed down dramatically- will it get better?

Hi,

my line has finaly been transfered from ADSL2+ to VDSL2. 

I had a predicted speed of about 10Mbs- On ADSL 2+ I was getting about 6Mbs-

I am about 2.5km from the cabinet.

My download speed has dropped to 4.4Mbs according to my BT smart hub

 

Is it likely my speed will improve or am I best downgrading to ASDL2+ again??

Thanks

At that distance from the cabinet, VDSL may not be any better, and its likely to disconnect more often. ADSL2+ is generally more stable and of consistent speed.

The actual cable distance may be further than that, as the cables do not run direct.

I can see the figure for ADSL2+

Max Observed Downstream Speed (Mbps) -- 6.16

 

That was better than expected, so your line performs better at ADSL2+ frequencies, that it does on VDSL.

As the handback speed on VDSL is only 4.1Mbs, it would indicate that Openreach do not expect a lot from that service.

My personal opinion would be to revert back to ADSL2+, as you are likely to get better long term stability, especially if crosstalk increases as more people get connected to the cabinet.

I agree with @Keith_Beddoe, you would have a better quality of service on ADSL2+.

Thanks. I will wait a few days to see if it improves at all. If not how do I revert back to ASDL2+?

Just contact BT and explain that you are getting slower speeds on VDSL, they may not be inclined to that (due to the estimates being higher on VDSL), but try to enforce that you're receiving a slower speed. If you get stuck, let us know, and then hopefully a mod can investigate.

Re: ADSL2+ to VDSL has slowed my speed down dramatically- will it get better?

Since my line was swapped to the VDSL connection from the ADSL2+ connection it has developed a lot of "static" particularly when I first pick up the line it then usually settles after a few seconds. - This occurs even if I plug directly into the master socket.

It is intermittent- At times it is bad enough not make it difficult to hear what people are saying on the phone- at other times it does not seem to be a problem at all…

This has only started happening again since line swapped over- Could something have happened to how the line is connected in the cabinet / exchange when being swapped over??

Thanks

Probably a bad termination in the cabinet.

Just report it as a noisy phone line.
