Hi all,

Over the last few days out internet has been dropping out fairly often. The only thing I can relate this to is that we got upgraded to the "better network" (LLU i'm guessing) about 10 days ago. Sync speeds are being really random:

DSL Status: Connected
DSL Modulation Mode: ADSL2+
DSL Path Mode: Interleaved
Downstream Rate: 6232 kbps
Upstream Rate: 679 kbps
Downstream Margin: 2147483644 db
Upstream Margin: 7 db
Downstream Line Attenuation: 29 db
Upstream Line Attenuation: 31.5 db
Downstream Transmit Power: 12 db
Upstream Transmit Power: 21 db

As you can see the downstream margin is really messed up and I believe that 2147483644 is the arbitrary number that is the maximum value an integer can hold?
Also the downstream rate is less than half of normal and upload is down by about ~300kbps too. I can reset it and sometimes it syncs at the full rate (17/1) but then it just leads to a drop out and when I reset I get something like the above. Anyway would anyone at Slingshot have an idea of what's going on here? Possibly dodgy modem?

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?

Just did a reset and resync'd at still sub-optimal speeds:

DSL Status: Connected
DSL Modulation Mode: ADSL2+
DSL Path Mode: Interleaved
Downstream Rate: 8345 kbps
Upstream Rate: 803 kbps
Downstream Margin: 6 db
Upstream Margin: 7 db
Downstream Line Attenuation: 29 db
Upstream Line Attenuation: 7.5 db
Downstream Transmit Power: 12 db
Upstream Transmit Power: 21 db

Also when it desyncs the DSL light flashes and then goes away and then flashes again and repeats forever until I reset.

Most probably a physical wiring issue.

Do an isolation test to confirm if it's in or out of your premises, then escalate it to the helpdesk.

I highly doubt that considering i've been at this place for almost 2 years now - the DSL light generally struggles to connect which seems too co-incedental following an upgrade on the cabinet

afaik the better network has to connect to an exchange not a road side cabinet?

Well, the two primary things that would cause repeated loss of DSL sync are faulty or misconfigured equipment (at either end), or the physical wiring between the two.

Given that's it's only the last couple of days you've had a problem, it's less likely to be equipment config, and more likely to be a wiring failure such as a broken, corroded or badly made joint. If you do the isolation test to confirm it's not on your side of the demarc, then contact your ISP's helpdesk who can arrange to check their side.

What cabinet upgrade are you taking about - you indicated you have been moved to ULL gear, not a cabinet?

I had a customer on Chorus gear at exchange, Telecom customer. They moved to Vodafone Red network, then there connection had major issues. Dropped to 2Mbps, lots of disconnects etc. their connection wasn't great to start with, but was relatively stable.

Installed a master filter, went from 2Mbps to 17Mbps and rock solid.

Never discount your internal wiring being at fault.




Chorus has spent $1.4 billion on making their xDSL broadband network faster. If your still stuck on ADSL or VDSL, why not spend from $150 on a master filter install to make sure you are getting the most out of your connection?

Sorry yeah I wasn't saying it wasn't the case but based on the circumstances it seems highly improbable. Slingshot recently "upgraded" us to the "better network" and I believe things were going find until I set the modem to connect through Multimode rather than ADSL2+ and this moved us onto Annex M. I've since switched back to ADSL2+ but still getting the drop outs.  What exactly is an isolation test?
P.S - We're on Naked BB

Edit: We'll see how long we last this time. Looks like geekzone doesn't allow you to edit edited posts so I can't keep updating the desync list.

Never rule out house wiring as this degrades over time! This is a big mistake end users do not take into account

Yeah I understand the major pros of getting one but i'm in a rented house and most likely moving out very soon. Had about 10 drop outs today but going strong atm! *touch wood*

Still being dodgy today. Was working when I woke up however the sync speeds were at about 1/3rd of what they have been so reset the modem. Took a while to get back on, synced at 2mbps so reset again. Wouldn't connect. Switched to a different jack point, ended up connecting but syncing at about half what it can get. When it can't connect the dsl light starts flashing, goes full and then turns off, and the process is repeated.

JokezNZ: [snip] What exactly is an isolation test?


If you read through the troubleshooting links in the first reply to this topic, it will teach you how to do it.

You will then have a good idea as to where the problem lies, internal or external, and this can be passed to the helpdesk.

Try lock modem to ADSL1 only
