Hi There

got a few questions if anyone can help answer these ?

So my house has been rewired after a Renovation and my VDSL speed has dropped from 54mbps to 42mbps after a wiring change, the new router jack point is closer to the Master Jack that in previously was
my current line attenuation is 30.9db up , 12.3 down using the Vodafone HG659 standard router

Before the rewiring I had a master splitter on the first phone jack inside the house and a vdsl splitter on the jack where the Router plugs in ( was at other end of the house)
I checked yesterday and the main jack point now has set of wires going off to the home phone line I assume , and a blue and white wire cabled to a CAT6 which now runs to the Router Jack point where the blue and white wire connect to the jack point. I cant see any splitters anywhere now.

So from the First phone jack in the house, it has cat6 cabling to the router jackpoint.

My question is should I be getting splitters reinstalled, 10+Mbps drop after rewiring points to a problem right ?
The Cabinet is at the end of my drive <30m down the road on my side , that's probably irrelevant , but it is very close

Cheers

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?

You may find the Master splitter has been move to the point of entry on the outside of the house and you only require one not one for every jack point in the house

So i checked all the jack points and did some tests , there is definitely no master splitters , i unplugged my home phone and my vdsl went from 42mb to 58mb , plugged it back in and it reverted to 42 , removed it , then back to 58

definitely some interference or something ? guess ill need to get some splitters installed.....

Get a master filter installed, What city are you in? its possible Coffeebarron could do it for cheaper(and likely better quality...) than Chorus will charge.

you look to be on a 17a profile based off your sync speed, i wouldnt wanna loose that and drop back again


do be aware, at 12.3dB your line is actually rather long for your profile, and crosstalk could cut your speed pretty quickly. However i suspect your attenuation there is ballooned slightly too Due to your internal wiring.

I would get back the people who did the wiring and ask why they did such a crap job. Removing a master filter shows they don't understand what they're doing.

Cocopop: So i checked all the jack points and did some tests , there is definitely no master splitters ... guess ill need to get some splitters installed.....

I'm not an expert, so my terminology probably won't be correct and others should feel free to correct me, but I have had VDSL installed in my last two houses so know a little as an end-user...

Which jack points have you looked in?  You should only have one master splitter (not "some") and it should be in the external termination point (ETP) which is the little white box on the outside of your house where the wiring comes in.  Usually you need a three-blade screwdriver head to open that to look inside, although sometimes you can do it with a normal flat-bladed driver.

In basic terms, the splitter will separate the wires used for data/VDSL from the wires used for voice/telephone so that your modem is on separate, dedicated wiring with no interference from anything else you might have plugged into phone sockets (phones, your Sky decoder, a monitored alarm, etc.) but this means that there is usually only one socket in the house where you can plug your modem in.  Is there a chance that you have a splitter in the ETP but your modem is plugged into a socket that's still sharing the phone line with other devices, rather than the one that's been "split" off?

if you can connect the modem and get a connection on  more than one jackpoint you dont have a master filter/splitter.

Yep i know im on 17a , got chrous to check , that was before i pulled my home phone out and the speed increased

im in auckland , greenlane

the ETP is outside the goes into the garage roofing, i can get into the roof and see the line splits to home phone and 2 wires connect to cat6 , which goes to the router jack

i know pre renovation there was a master splitter in the roof where the lines split and one on the router jackpoint , so there are none now , i doubt one is installed in the ETP coz if the electrician knew to do that he probably wouldnt have cut the current filters out to start with

yea not sure about the attenuation as the cabinet is on my side of the road less than 30m away
I definitely need to get splitters of some sort though, because at the moment my home phone is permanently unplugged so i can maintain 58/10......priorities haha

In that case definitely contact Coffeebaron and get him to do a master filter install. Since you are in Auckland. If the previous workers removed a master filter I doubt they would know how to correctly install one.
