So after a couple of weeks my VDSL has settled around 27.5 down and 3.2 up.

Been away a few days and checked it when I got home today - down to 19.1 and 2.2.

Is that level of change normal?

Hi,

It can vary depending on many factors. Hio77 will be able to list 1000 of them. Ill get him to reply.

sounds likely to be be DLM settling in unfortunately...

although yours is moving around a bit, IIRC wasnt your house wiring not quite to scratch?

its ok though, im sure your speeds are still faster than TimA :3

Possible - weather has changed from the warm dry weather of the past few weeks. How does weather affect it though?

if its changing the resistance of your line, it could account for your speeds, but im tempted to say given your lines distance, your simply seeing DLM having trouble settling...

DLM seems to be the explanation for everything, even when it doesn't make logical sense.

I was set up on Vodafone VDSL yesterday around noon. My modem is connecting a 30Meg down and 10Meg up, but SpeedTest.net using Vodafone's server gives me between 9-11Meg down and 0.8 up - which was exactly what I was getting with ADSL from a different provider.

I'm a little disappointed abour the theoretical connection - I am across the street from the cabinet, my noise and impedance values are very good - so my wiring should be fine - and I was hoping for more than 30Meg down. I'm REALLY disappointed that for actual performance, there is 0 difference so far between ADSL and VDSL.

I did speak with tech support yesterday, who told me that it must just be DLM, although they put a note on my file that my test results were sub-par. I'm not sure I'm happy to wait 10 days before I go back to identify that somebody has missed something - it's just not reasonable to expect that I'm getting less than 10% of the upload speed that I should, and that the system will dynamically tune for 1000% improvement over what I now have.

Sounds like your still on the adsl2 profile and havnt been moved to a vdsl profile to get your sync speed

This does sound like the most likely explanation, however I moved from Slingshot ADSL to Vodafone VDSL. The profile is set by the provider and not somehow configured in the cabinet by Chorus (is it not?). If so, how did Vodafone onboard me as a new customer with an ADSL profile when I have VDSL service?

defiantly sounds like a profile on vodafones side.

line stats? unless you had a good line (which 9-11mbit before VDSL infers not.) 30Mbit might be the best you will manage.

I can't recall what the new modem with VDSL splitter reports, but the old ADSL modem indicated 0.1dB of attenuation, I think the new modem is reporting 0.0dB now. I can check tonight and confirm.
