I would like to get VDSL mainly to upgrade my upload speed from the standard ADSL speed of <1mbps to the VDSL 5-10mbps. On the chorus compatibility map it says that VDSL is available at my address, however internet providers say that my line attenuation needs to be below 10dB for them to install VDSL at my address. My downstream attenuation is 24.7 and upstream is 9.5.


My question is : what would happen if they installed VDSL at my address even though my downstream attenuation is above 10mB. As I am really not to fussed about the download speed, would my upstream attenuation being below 10dB mean that I would get atleast 5mbps upload ? (as VDSL states upload speeds of 5 to 10) or is it actually impossible for VDSL to be installed as the downstream is above 10dB.

I ask this question because if it is possible I would extremely appreciate the upgrade from 1mbps to 5mbps upload speed.

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?

Depending on how far you are from the cabinet and how lower your down attenuation would be after a master filter install and VDSL is provisioned your line stats may or may not be suitable for it.

You can also follow me on twitter here @kiwifortw I do twitch streams every now and then at :)

get your ISP to run a prequal

if that comes back that you cant get VDSL i highly doubt chorus will connect you as your connection will probably degrade others

Downstream attenuation is waaaay to high, max chorus will install is 12dB. At 24dB your download speed would plummet to well below what you get on adsl, and maybe not even work at all.

With downstream attenuation of 24.7dB, it just won't happen. Forget it.

Jase2985: get your ISP to run a prequal

This. Doesn't really matter what your down or up attenuation is, a pre-qual will give you the final answer. IF they've already done this and said no then you're probably out of luck, though it may be worth checking with a second ISP.  

TBH It's probably unlikely with your current attenuation, but that may be affected by internal wiring, etc so can't be sure. Also the attenuation for the prequal is (or I should say was) measured at a different frequency to what either ADSL or VDSL shows, so the pre-qual really is the only way to find out.

You're not going to get VDSL2 with such poor line stats, however your poor line stats could be a result of poor internal wiring.
