Hi there,

Was hoping someone might be able to provide feedback and/or advice on my situation.

Moved from Greenlane to Torbay. At my home at Greenlane I was getting over 20Mb/s connection speeds from my Snap ADSL2+ connection. Organised my move with Snap, cut over happened as promised.

To my shock & horror I was connecting at 2Mb/s!

Straight away I crawl under the house to check the wiring. Found a very long cable from the jackpoint to an old style splitter from when the house had three phone jackpoints. 

I removed the loops, shortened the cable from the ADSL jackpoint & connected it to the feed from the street (yes I used gel caps). Now I'm getting 3.5Mb/s.

Purchased a master splitter & wired it in which toook me to 4.5Mb/s

Attenuation has gone down from 44Db to 38Db.

Logged a fault with Snap. Chorus have fixed faults in the feed & now I have 6.6Mb/s. The helpful person at Snap told me that Chorus have reported that this is "in spec" & closed the fault (attenuation still 38Db).

This seems really slow to me. There is a cabinet 800m from my house so I would have thought I would be getting at least 15Mb/s.

Does this seem normal to anyone out there? Any suggestions what I can do now? I will gladly help out a Chorus person if they can improve things for me.

Thanks

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?




I am the Geekzone Robot and I am here to help. I am from the Internet. I do not interact. Do not expect other replies from me.

Have a look at your address on this website. http://www.chorus.co.nz/network-upgrade-map

What result do you get? It should say below the map what speeds you can expected to get on any DSL ISP.

Hi,

Sorry, I should have posted that info:

"Broadband > 10 Mbps"


Thanks

do you have the actual specs from the modem?

as i dont believe i have seen any that say they connect at Mb/s most report it in kbps or bps.

just because there is a cabinet 800m from your house doesn't mean you are connected to that one, or that the cable runs directly there.

and just because you got 20Mb/s in greenlane doesnt mean you will get that at another location

and finally 6.6Mb/s is well about the minimum of 32Kb/s over a 15 minute peroid

Hi,

The actual speed is 6600000bps. I just converted it to something easier to read.

I'm fully aware that achieving speeds in one location don't mean you will get the same in another location & that I'm not necessarily connected to the cabinet I saw down the road. Thanks for the input though.

I am however roughly about 800m - 1km from all the cabinets in my area.

I'm curious to hear whether or not this really is "in spec" or not.

It's not exactly that value. I'm at work right now so I can't give you the exact figure but it's 66xxxxxbps

I'm am really surprised at such a slow connection. Others in areas near me are getting approx 15000000bps (15Mb/s)

must be a bad line somewhere

do an isolation test or if your confident test at the ETP to eliminate the house wiring as  the issue

Good tip. Planning to do a bunch of testing this weekend to further rule out house wiring. So far have removed everything from the EPT except for the line to my modem.

if you test with the 2 wires coming in and and connect straight into your modem and there is still and issue you could lodge a fault with your ISP. though i dont know how far/urgent it would be

Really need to know up and downstream sync rates, attenuation and noise margin to make any informed comment.

The sync rate seems a little low for the attenuation but not too bad. The killer is the attenuation which would be several km of cable, certainly a lot more than 800m. Generally speaking if you are in a >10Mb zone you should be getting higher than that, but there are exoeptions.

theasset13: <snip> There is a cabinet 800m from my house so I would have thought I would be getting at least 15Mb/s.


If you are willing to Private Msg me your Address and possiblely the name on the front of that cabinet - ill take a look and see if I can work out which set of xDSL equipement you are actualy connected to.

Just because you are geographically 800m from a cabinet does not mean the local loop length is 800mm. It may well go the opposite way down the road and then come to your place. And to answer your next question, no you can't get Chorus to re-direct it.
