Hey Guys,

So lately i've been having terrible line speeds with slingshot on their AYCE plan. Screenshot is below showing all the xDSL statistics.



I'm not too knowledgeable about all this, but I've tried an isolation test (except I was unable to find a 'Master Socket') by disconnecting all devices connected into the phone jacks, and connecting the modem in directly. I did this test with all the jacks in the house just to make sure it wasn't a problem with the jack itself, and because I couldn't find the master socket or a junction box (It must be hiding somewhere under the house or somewhere I can't see I guess?).

I'm living on the corner of Trafalgar Street/Forbes Street in Royal Oak/Onehunga.

I have no idea whether my connection is to an exchange, cabinet or conklin.

I do have an alarm in the house, although the speed problems have only arisen lately.

I have also been having rather frequent disconnections lately (sometimes one a day at a random time, other days 20 in a row within an hour).

When I called slingshot a while back, they said they could send out a technician, however it might incur charges depending on what they find, so I was keen to get some advice on here before heading in that direction.

It may also be worth noting that there have been quite a few road works around me lately. They are only upgrading the footpath, but my first gut feeling was that there may be some connection, so I thought I would let you know.

Any advice would be greatly appreciated.

Cheers,

si2zle

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?

Hey Sideface,

Thanks for the quick reply, are you able to see my second post? I posted the link to the image in that post.

Just as an update, I found the Master Socket by taking the face plate off (another thread on these forums said that it had a little yellow capacitor inside it) and I had already tested the modem in that socket, with the same result as all the other jacks.

Your attenuation is VERY high - no wonder you have a slow connection.
Your original post implies that your connection used to be faster - is this correct?
Do you have a master filter?

Sideface: Your attenuation is VERY high - no wonder you have a slow connection

The modem is displaying it strangely; it's actually 38 dB, not 380. The data rate is far too low for 38; I used to be at 54 before the local cabinet went in and I still got around 4.5 Mb/s.

How do I go about lowering the attenuation? Is it common for it to still remain that high at the Master Socket?

Ah ok, I thought it wasn't too bad as I read it can go up to around 50 or so? Any other ideas based on the stats?

38db and 54dB are both very high figures (your modem shows 0.1dB units)
So you have bad wiring in your house &/or outside your house.

It looks like you're on an exchange, and you're in the "10 Mb/s zone" so should be getting much faster speeds (and it sounds like you used to).

When something similar happened to my connection (dropped from 12 Mb/s to about 3), it ended up being a problem with the cable in the street. There hadn't been any roadworks or anything, and as it turned out the cable had simply corroded over the years. The technician was amazed that it worked at all!

So, these things can happen. If nothing's changed at your end then it may indeed be a problem in the street.

Sorry si2zle but the yellow capacitor doesnt mean its a 'Master jackpoint' - It will only be a Master if it has a M embosed on the bottom right @ the front  - many of the older version of jackpoints had capacitors in them even if it isnt a Master.

If you dont have an ETP (external test point), the jackpoint you are looking for to isolate your house wireing from the outside world would be the one that has the large black cable (probable wire colours Yellow/Black & White/Brown) - if you find it dont remove that cable but the one leading away to the rest of the house and plug your modem in and retest - if you still have major attenuation results - go back to your isp and report a fault with your line.

It is displaying correctly, it's just the unit of measurement is 0.1db, it also looks like he's on ADSL1

The capital M is embossed in the bottom right - thanks for the heads up, didn't notice that at first!

How do I go about checking whether I am on ADSL1 or 2?

kornflake: Ask for a Port reset


Do I simply call the ISP and ask for this?
