First time on VDSL - Is this correct?


[link to this post]
 
I've always had cable broadband in the past but today is the first day of using VDSL. The line was activated this morning and I'm supposed to have a minimum guaranteed rate of 40Mbps. So far, I haven't been able to achieve more than 7Mbps down or up. Is this normal for the first few days?

No

Are you able to see the connection speed figures from the modem?

From the router (Vodafone):

DSL status information
Line status Show Time
Link type Fast path
Bit rate
Downstream Upstream
Actual data rate 34604 (Kbps.) 12056 (Kbps.)

No more info than that I'm afraid.

Speeds of 32 Mbps down and around 10 Mbps up should be coming from speed test results.

There is a lot of upstream errors, so have you ensured that all phones/sky boxes have microfilters on them? Also tried letting the modem connect at the test socket.

VDSL general starts at the highest speed and management systems only slow the actual data rate figures down after a day or two and keep adapting for the length of time you have the service.

Getting 7 Mbps in both directions sounds almost like a PC configuration issue, what is the result link from a speed test at http://www.thinkbroadband.com/speedtest

I think that your problem is not unique. I got VDSL in February and thereby swapped a steady 8Mbps ADSL service for a very flaky 5Mbps VDSL service. It took quite a long time for things to setle down and in the meantime I recabled my telephone extensions with cat5e which may have helped.

It all came good in the end and I am now Synced at 70.9 Mbps.

Good luck.

Along with MrS's comments, I believe there may be some wiring or connection issues at the premises - with 21 dB attenuation the max attainable should be well above 40 Mbps and probably into the low 50s ... and if you are on a 40/10 package a sync close to 40 and an SNR well above 6dB.

What have you got plugged in to your phone line? How is it wired? How many extensions are there?

First, I had a line splitter plugged into the socket with the phone connected to one, and the filter connected to the other.
I've since got rid of that and plugged the filter straight into the socket and getting the same results. I'll try the test socket in a sec.

Somehow worse.

My Broadband Speed Test

This is from the test socket. A lot better but still not the MGLS.

From the router:

DSL Mode
VDSL G.993.5 (VDSL)
DSL status information
Line status Show Time
Link type Fast path
Bit rate
Downstream Upstream
Actual data rate 43537 (Kbps.) 12347 (Kbps.)
Operating data
Downstream Upstream
SNR Margin 6.3 dB 6.1 dB
Loop Attenuation 21.8 dB 21.9 dB
Error counter
Indicator name Downstream Upstream
FEC Corrections 0 0
CRC Error 0 3728
Statistics
Transmitted Frames Received Frames
Frame Counter 55756 74904

Upstream CRCs are still continuously incrementing. Only the router is connected at the moment, no phones or extensions.

Your sync speed is up at 43.5Mbps which is way more than before. And you are achieving 30.6 so well up on download speeds. You need to find out why the single thread is slow whereas the x6 is "getting there". Do you have any AV running on the PC?

Are you sure that there are no other extensions connected before the master or to the master's incoming terminals?

Only Windows Defender, which was never a problem when I had cable. I also tried turning the firewall off on the router, but no difference.

There's definitely no other extensions. The RJ11 is connected to the filter, which is connected to the test socket on the master socket.
