 I'm on a crappy old ADSL2+ (not that the 2+ matters) connection with no plans for upgrades ever according to Chorus, so trying to squeeze as much out of the connection as possible. Wondering two things:

1) Where the cabinet is - I can't make a clear guess from the Chorus map: http://gyazo.com/b59a86c38ae11dab744b5e129ad5aa7d (PM me for address if you have appropriate credentials)

2) Any easy way to tell if we have a master filter installed? The house was built in '99 and when we moved in, I noticed I could only get ADSL working from one particular phone jack in the house which made me think there probably was a master filter. Noticed the other day however that when we plug a phone into a jack in a separate building that the internet completely drops out. Makes me think that the line comes in, splits to each of the buildings and then there's a filter at the house to only the one jack.

Getting around 2.9Mbps on a good speedtest, modem says 3.37Mbps. Had up to 3.2Mbps on a speedtest a few months ago. Got a vodafone station so no line stats I can see unfortunately.

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?

If the modem only works in one outlet, you almost certainly have a master filter.

Can you borrow a different modem to grab the line stats?

Looks like the actual exchange is in Pukerura/Camborne which would explain the awful ADSL1 sub speeds and you're on it so at that distance that's expected. 
There are things you can do though.

Get a master filter which is $20 if you can do it yourself, or a $150-200 from Coffeebaron or from your ISP and that would be a Chorus callout.
Moving onto a WISP or Wireless ISP.
Satellite ISP
Moving house to somewhere closer to the exchange.

If you did have a modem that did show stats that would be lovely if you could post them but other then that I think that's the best you can do.

I do know how it feels to be on sub ADSL1 speeds and so do a few others #outram

quickymart: I wonder if this is a Conklin situation?


Wouldn't a Conklin show erratic stats and ping times?

Erratic throughput and latency yes, but no reason why line stats should vary.

OP isn't on a Conklin. They're on a fibre fed ISAM but so far from it they get poor speeds.

As this is the edge of an urban area nothing is going to change (for all intent purposes nothing is actually wrong).

Sorry haven't had time to find out if you are exchange or cabinet, but either way distance is the issue. At least it is ADSL2+ so you are actually getting your 2-3Mbps and not 300-500Kbps :)

Possibly there is a master filter, but they must have missed the shed. Common for some rural properties for the line to come in via the shed / barn before it reaches the house. May be worth getting Chorus out to investigate the wiring and install / reinstall the master filter.




Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

Goroglen Rise I'm sure is feed from PKB Exch (Pukerua Bay Exchange) (or it was in 2013) which would make terminals apprx 3.3 to 4.3 km from the exchange with mutipule laterals off up the rise (depending on the cable pair)

I thought they may not be, but worth a shot, right?

Sorry for the late reply - thanks all for your comments.

RunningMan: If the modem only works in one outlet, you almost certainly have a master filter.

Not easily, sorry. Have been thinking of getting a different modem though, since the vodafone station likes to drop down to 1.5Mbps (or worse) spuriously for no apparent reason. Any suggestions on cost-effective modems for this sort of long line?

InstallerUFB: Goroglen Rise I'm sure is feed from PKB Exch (Pukerua Bay Exchange) (or it was in 2013) which would make terminals apprx 3.3 to 4.3 km from the exchange with mutipule laterals off up the rise (depending on the cable pair)


Hm, interesting. That's a pretty decent distance.

Thanks for the info! No worries, I thought you might've been pretty busy!

Got any mates up in Pukerua bay township ?

 

 

They appear to be getting UFB by mid 2016, so you could look at look at running a wireless P2P link,

 

 

They also appear to get VDSL at the mo

Here's a screenshot from one of the more detailed Chorus coverage maps. That's a yellow 1Mb/s area selected, and a 5Mb/s area next to it.

You can lodge a fault with your ISP and when the technician comes out ask if you can be put on a 'Long Reach' DSL card in the exchange and sort your internal wiring so it is the only jackpoint on the DSL circuit from the master filter.  Pukerua Bay exchange has a couple of long reach cards installed to give DSL service to customers in Paekakariki Road up the top of the hill some 7-8kms away.

Sorry to bump an old post, but changed ISPs so have a modem with stats now. Anyone care to comment on the attainable rate given the attenuation and SNR margin?

That attentiation suggests a line a number of km long. Not a bad sync rate for that length line, as long as it is stable.
