I had VDSL installed yesterday at a new place I have just moved into (Blockhouse Bay Rd, 1026). I signed up with Slingshot and they were going to put me on ADSL initially due to the VDSL installation waiting list. Surprisingly, someone from Chorus came and installed VDSL on the day my connection was supposed to go live. Due to this I have no idea what my ADSL speeds and stats would have been.

I noticed that my VDSL speeds were nothing flash. My router is reporting the following stats:
Attentuation: 23.0 Down, 102.3 Up.
Rate: 17mbs Down, 8.3mbs Up.
SNR Margin: 11.7 Down, 12.2 Up.

The bit rate seems hardly better than what I would achieve with ADSL?
I have read that my attenuation is far too high and that the Chorus technician shouldn't have let the installation go ahead. Is this true? Should I cancel my VDSL?

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?

Definitely higher end of the spectrum.
Log a ticket and see what they have to say. Chorus back end will reject it or pout it through if they see its not to spec.

The up-link speed you get on VDSL will be much better than attached to ADSL

Thanks I will do that. I was thinking I might be better off with ADSL and a dual band router because I am getting a few wifi issues e.g. disappearing completely and last night I was copying a file to my NAS from my laptop over wifi and the transfer rate was about a meg/sec. It is a bit faster today but I am used to my NAS upload speeds being at least 11 megs (which I understand isn't a very quick write speed anyway).

Could also be a dodgy lead in or issues with the copper back to the cabinet / exchange. Worth getting the tech to test on the pole / pillar and see if there are any major differences.

I'm jealous smile
With a downstream attenuation of 23dB, you are very lucky to have VDSL at all - and your speeds are pretty good considering.
I'd stick with VDSL unless the much-improved upload speed is of no use to you.

1MB/s is probably about right on 2.4ghz wifi these days, especially in urban areas.

for your attenuation, you speeds seem about right.

your wireless speeds are a whole different topic to your VDSL connection.

where along blockhousebay road is this? having lived in the area for a bit, know it pretty well. sizable bit of the coverage is actually exchange vdsl, which doesn't often go as far in terms of speed.

suspect you could simply be on the borderline though.
