I was just wanting some advice. and I will start with my set up and go from there.
I renovated my house back in 2005, When I did this I completely ripped out all the phone wiring and installed cat 5 networking everywhere. All the Cat 5 goes back to a central point and where the switches and modem are. All CAt 5 wiring was run separately to electrical cabling including separate holes down the wall.  The phone line goes into the central hub cabinet. the modem connection is soldered onto the main phone line. The phone then goes through a Marqure Magnetis MM3200B splitter to a distribution board that has the Alarm disconnect and phone line patch cables. All patch cables are Cat5. The Phones and networking are all patched through the central hub, There are no dedicated internal phone lines
I noticed recently my modem connection speed was down to 2MBits. If I disconnect all the internal phone lines  from the distribution hub (leaving the filter attached to the incoming line) I get connection speeds of 5.1M
If I reconnect any thing to the Phone distribution hub (even a line to the phone without the phone) the connection speed drop dramatically 3-3.6M
My question is is this normal, Would the connection speed drop quickly like that even with just 2 phone lines connected or it something else going on (noise maybe) It does not seem to mater what cables are connected the result is the same
I have checked all the cabling out ans tried a million different combinations of patch leads and internal wiring always with the same result.

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?

It would seem that you very clearly have something wrong with your wiring or how it's hooked up.

Soldering of phone wiring also isn't recommended as it can corrode depending on what solder was used. You should use scotchlok connectors.

Splitter may have failed if playing with the phone side disrupts the xDSL side.

Any chance of some photos of how it's wired?

"What is resonable ADSL 2+ speed"

Faster than DialUp


There will be some loss across the line. Maybe an earth somewhere?

Which wiring standard did you use? A? B? Or other?

Here are a couple of Pix, I'm ashamed to say its a bit of a mess because I've been pulling wires in and out all day
 The moden line is connected under the yellow heatshrink hidden from view, the phone terminates in to the distribution hub (yellow heat shrink), The brown and white are to the filter and the blue and white are from. The blue cat 5 cable is the alarm and switches only the circuit the phone line are in. The connection at the top next to the blue and white wire are the Voip phone connection.
The top 2 Gray patch cables are the Voip phone and the bottom 2 are POts.
Disconnect bottom 2 gray patch and the alarm 5.1 Mb connect the bottom 2 and no alarm 3 Mb.
I was beging to suspect the filter and as a new one is only 22 dollars I think I will replace it.

Replaced filter all good now connection speeds of 5220kbs

PS by the way , my proffesional opion is a good solder joint will beat a crimp every time. Far less failures in my experience.

I always crimp. If there is an issue with a crimp something is up. Conductive solder is always going to be better as long as its shielded properly.

Good to see you've got it sorted.

The problem with a solder joint (even a really good one ;-) ) is that it doesn't waterproof the cable ends, and allows moisture ingress which will lead to (often unseen) cable damage and reliability issues. A properly used scotchlok gel crimp avoids this issue.

Solder doesn't protect against moisture and can suffer from galvanic corrosion. That's why gel filled scotchlok connectors should be used because they avoid both issues.
