Hi,

I have reason to believe I have a wiring issue !

When people in the house use the phone the DSL seems to drop. I can see the stats below but dont get any IP from the ISP. After a few minutes it reconnects. On some occasions and as of late more frequently it takes me a few reboots of the modem to get anything going again!

We have a master splitter installed as have a buglar alarm and about 9 jackpoints (only 3-4 jackpoints are used).
We have phone on the red/white pair and DSL on the blue/green pair (sometimes its blue/white / blue). Theres 4 jackpoints for the DSL (obviously I only use one of them).

About 7 weeks ago I had downer and/or chorus out (via call to vodafone) and they told me they could see I had an issue but didnt check the internal wiring. Instead they swapped out the port in the exchange? and changed the cable pair comming to the house. Problem seemed to be fixed BUT in saying this when we tested, the phones were not in the house at all given we had moved out for EQ repairs and as such moved everything out.

Ive checked most outlets in the house to see if there are any loose wires.
We just moved back into the house after some EQ repairs so, im wondering if that has rustled somthing about given that all the lights, switches, power outlets get dropped from the celings and walls for paint and plastering.

Does anyone here agree with me that I need to get them back employing the wiring and maint I pay for?
Im 99% sure its wiring... but I could have a dodgy netgear adsl wifi router (less than a year old)....but then Id be dropping out more frequently if that was the case rather than just when the phone rings / in use.

I also notced majority of jacks have the capacitors except for 2. One jackpoint even had a second capacitor wired in and the capactor said "test termination". Looked like it was put there back in 1999.

The below shows when the connection and modem are working as it should;

ADSL Firmware Version
A2pD035d.d23e
Modem Status Connected
DownStream Connection Speed 16322 Kbps
UpStream Connection Speed 1144 Kbps
VPI 0
VCI 100

Line Attenuation Down 16.5 dB Up 9.3 dB
Noise Margin Down 14.1 dB Up 15.6 dB

The below shows when things are NOT working;

DownStream Connection Speed 15283 Kbps
UpStream Connection Speed1112 Kbps

Line Attenuation Down 16.5 dB Up 9.5 dB
Noise Margin Down 6.9 dB Up 15.0 dB

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?

Speedtest using speedtest.net and choosing Christchurch (where I live) and 'snap'. I believe we are on wholesale via vodafone as my ISP.

Down 13 - 14 Mbps
Up 0.9Mbps
ping 42ms

and yes I have moved around the modem to different jack points,
removed phones and put a line filter in / removed a line filter to see what happens.

If you have a splitter installed the filter won't do anything to the phone.

I suggest see if you can borrow a modem from a mate for like 1 hour or something to test it. If it works then its your modem.

If it still doesn't work I would then lodge a call to get the wiring checked.

I would test the modem just in case otherwise you pay the call out fee :)

Gooseybhai: Theres 4 jackpoints for the DSL (obviously I only use one of them).

That isn't normal, or particularly good. There should only be 1 for the DSL. Are you really sure there is a master filter installed?

I'd definitely get your wiring sorted. Also 9 jackpoints is A LOT.

ubergeeknz is correct. Normally for master splitter you have it going to 1 jack point only. Sounds like you might need to get the splitter guy in to have a look....

In all seriousness you need an expert in to look at your wiring.

You shouldn't have 3 or 4 jackpoints for DSL with a master filter. Your DSL should only work from a single jackpoint that is on the DSL output of the filter.

What sbiddle said. Having multiple outlets like this defeats the whole purpose of the master splitter.

Thanks guys.. Discovered the sky guy simply tapped off the phone cable running in the ceiling space to service the second decoder. This adds to my issue!

Going to borrow a modem and then look at putting that sky jack in star.... Need to also see if my master splitter is still there..... Should be.... Don't think anyone would have taken it out (lives inside the garage where the etp is). Yes I know it's strange to have this inside the internal access garage but that's how it was done 22 years ago when previous owners built the house. (Dsl installed back in 2007).

Any recommendations for calling a phone tech in chch if I can't get faults to sort this?
