Theres nothing i believe to configure in modem. Tried to connect the adsl account instead of vdsl but failing to connect.

Does telecom uses username and pass for adsl? It has the default logon details user@xtrabb.co.nz

ok ADSL is now working again.

but it is way way down below from my previous ADSL where I can get up to 18Mb/1Mb (down/up). and now this is what I got

Bandwidth (Up/Down) [kbps/kbps]: 664 / 10,272 Data Transferred (Sent/Received) [kB/kB]: 39.10 / 109.98 Output Power (Up/Down) [dBm]: 12.6 / 4.2 Line Attenuation (Up/Down) [dB]: 30.4 / 38.0 SN Margin (Up/Down) [dB]: 13.1 / 12.1

my previous adsl att: was only 10/20db (up/down) and now I get 30/38

I thought master splitter is to make this better... that looks like it get worst..

here's what I thought.. maybe with my current telecom adsl (I'm on naked) but still I got telephone line active on telecom, and this might contribute on high attenuation because it has active telephone line whereas with my previous slingshot adsl I don't have active telephone line

or

chorus will need to do something on exchange side to switch from VDSL to ADSL so my attenuation will go down.

pls help

I would say previously you were on slingshots own gear which runs a lower db thus making your speeds better

nahhh... the chorus tech mentioned to me it uses same port on exchange.

This is almost certainly correct. To get the 18Mb/s rate on ADSL that you had with an attenuation of 21dB would be near on impossible with an SNR of 12dB on Chorus gear. Would be possible with the lower SNR of 6dB on Slingshot gear.

but I do get 23db sometimes on telecom VDSL which gives me 19Mb but it would only last like 12 hrs then back to high attenuation....

this is my slingshot ADSL details just 4 days ago until I got telecom.

as you can see... it was perfect!!! what went wrong when migrated to telecom vdsl?
master splitter issue? or chorus will need to adjust something on cabinet from VDSL to ADSL?

I stand corrected. That does appear to have been a very good connection for the attenuation though, although it is showing a few errors.

I would say probably the master splitter installation was no good and has actually introduced more noise, looking at your current stats upstream of 664 kbps points to noise problem.

Your past stats shows very nice aggressive sync (assuming it was stable).

3 days uptime, ild call that pretty stable, but for the attenuation very aggressive...

as i said at the start, something doesnt look too happy in your line, and now that you have dropped back, it is most certainly the case.

get the splitter fixed (it should improve, not make it worse..) and maybe you will have a borderline reasonable vdsl connection in your future...

one thing I noticed on my connection is the FEC errors is growing significantly. like 1000 every min.
FEC Errors (Up/Down): 0 / 10,594 CRC Errors (Up/Down): 1 / 4 HEC Errors (Up/Down): 0 / 0

my previous DSL is zero on both up/down - while my new telecom adsl has these errors...

not really happy with the migration.. I just hope telecom listens and help me.

Btw, Yyrael was the only one really helpful - did even sent tech to help me but yeah, no offence with chorus tech but I don't think the techs came to my place is really good in troubleshooting... I already got 2 tech sent to my place but could not really help. One thing I could remember is when tech called their team and was able to increase my downstream to 19Mb then latency went low (22db). but yeah, didn't took so long and went back to slow speed...

I just hope this nightmare will be all over.. hopefully telecom can sort my issues... really really depressed trying to figure out what went wrong...

unfortunately, it would seem you may have got wacked with once again, another failure on chorus's part, and their techs trying to pull a quick one.

my recent vdsl relocation, took a month to get connected due to issue with chorus's techs failing to do their job correctly, look all around, its not a uncommon thing.

really something chorus need to step up on, with the uptake of vdsl, where a line needs to be done properly or it often will expose any issues almost instantly, the workmanship of some techs shines right through as terrible, its a great relief to see a chorus install go well at this point... goes to show there are some techs who take pride in completing the job to the right standard

guys, I found exactly the same issue as mine..
http://www.geekzone.co.nz/forums.asp?forumid=90&topicid=136405

Just checking with him what was the resolution but according to that forum it was a problem found on line connection (I believe cabinet).

Just really frustrated as 2 techs already came in but could not see the root cause (but yeah, one tech whisper on their back home and he said "I don't have tools to check line issues" I only got dsl speed tester...

Telecom, can you please help on this.. I would actually going to ask to cancel this account and not pay the termination fee as I am really depressed... but still I don't have choice as even I move to another provider I would have the same issue.. so this needs to be sorted... and this might resolved issue if I wanted to go back to VDSL..

oh btw, captured modem errors and here's what I got... (this is only 12 hrs uptime)
FEC Errors (Up/Down): 0 / 4,823,794
CRC Errors (Up/Down): 42,518 / 122
HEC Errors (Up/Down): 0 / 1,156

Ring up the broadband helpdesk on 0800 225598 and ask them to run a 24 hour line test in SPM.

I can run these too, but I am on holiday so would prefer that you went via the normal channels (as they do work!!)

It does sound to me like you had a dodgy VDSL install, which has happened more than a few times.

When it was installed did the Chorus tech run a new cable from the ETP (the box where the cable hits the side of your house) where the Master Filter should have been installed into to where the dedicated VDSL jackpoint is?? My guess would be no. If this is the case you are certianly not the first, nor will you be the last to have this issue.

If that is the case ring the Broadband Helpdesk and say to them "The Chorus Tech did not install a new CAT5 run from the ETP to the VDSL outlet, this isn't a Chorus spec VDSL install and a truck roll is required to get Chorus out to install that as per what Telecom has contracted Chorus to do. This is a incorrect install and should be treated as such"

Chrizvi: Does telecom uses username and pass for adsl? It has the default logon details user@xtrabb.co.nz

It doesn't matter what you put in there, as it's all based off your line. "user@xtrabb.co.nz" / "password" is what is hard-coded into the modem for username & password.
