VDSL was installed this morning and the downstream rate was 39 kbps.  When I came home after work it had dropped to 30 and is now down to 27!

I thought that it was meant to get better with time, not worse?

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

 



 

If you are posting regarding DSL speeds please check that

 



 

- you have reset your modem and router

 


 

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

 

- you are not being throttled by your ISP due to going over the monthly cap

 


 

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

 


 

- you read this topic and follow the instructions there.

 



 

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

 



 

- Your ISP and plan

 


 

- Type of connection (ADSL, ADSL2, VDSL)

 


 

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

 


 

- Your general location (or street)

 


 

- If you are rural or urban

 


 

- If you know your connection is to an exchange, cabinet or conklin

 


 

- If your connection is to a ULL or wholesale service

 


 

- If you have done an isolation test as per the link above

 



 

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

 



 

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

 



 

I recommend you read these two blog posts:

 



 

- Is your premises phone wiring impacting your broadband performance? (very technical)

 


 

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

It's back to 39 Mbps after a modem reboot.  I'll monitor it for a while and post again if I do need help.

do you mean mbit? 


your modem wont sync at 39kbit. DSLAM wont allow it.


post line stats. dont reboot your router, reboots (or lost syncs due to pulling cable out) could negatively affect your line.

this sounds like DLM simply settling in. although it could indicate a fault if your line wasnt installed correctly (unlikely)..

cant really many any prediction on that though, as your lack of posting line stats, after being ask multiple times, would indicate your probably going off speedtests.


so once again

please post line stats. we cant do alot to help you if you dont give all the information. you have not stated how long you have had VDSL for iver.



lastly, DLM doesnt only make lines better, it can also make lines "worse" as DLMs purpose is to achieve best speed and stability.

ok. so what i note here.

- your line has a few errors on it.
- your snr margin is running high.
- your currently running on DLM-4
- your line is reasonably long. be glad your hitting near 40mbit.

what this could mean, is as mentioned before, your installation wasnt done correctly (once again unlikely) or there is a sizeable amount of crosstalk in your area.


insure your resyncs are caused by DLM and not your line loosing sync.

The phone line that the VDSL is on sounds "crackly".

Also, we aren't far from the nearest cabinet - 165m total down the drive and along the road.  Why do you say that it's a long line?

is it a naked line or not? i didnt think orcon did clothed lines.


165M by walking/driving sure. cables dont go like that though.

best example of this is TimA, his cabinet is right outside his fence. his cables travel up the road and back - quite a funny story.. 400M rather than like 10M


Attenuation (0.1 dB): 129

thats a 12.9 dB attenuation, which would be about 1KM.



ild ask orcon for what your attenuation prequals at, and take it from there.

OK so that's not a good sign at all.  You should really lodge a fault.

Yes I've seen this, a friend had a cabinet about 20 meters away from his house, his phone cable doesn't even go to that exchange as its on the other-side of the road.
My personal cable is just over 800m from the exchange and I could tough a stone and hit the exchange...

Can you expand on that - the VDSL voip line sounds crackly or, if you plug a phone into the POTS landline into the house that has VDSL on it, that sounds crackly?
