I have a lot of static noise on my phone line, so much its hard to have a conversation on the phone. Through a process of elimination I've identified my router as the likely culprit (Linksys X2000).

To give a quick bit of context on my setup:
I have two jackpoints in my house - one in the kitchen and one in a bedroom. Both jackpoints are on the upper level of my house and are fed by their own dedicated cable runs originating at what I assume is the incoming phone line which pops in through a wall under the house. The incoming cable (yellow and black pair) tees and feeds the two individual cables (yellow to red and black to white strands).

Each jackpoint feeder has 6 component strands, red, white, orange, green, black and blue. Typcial length from the incoming cable to each jackpoint is about 8-10 metres. The blue cable from both feeder cables are connected together and terminate at each jackpoint. So I'm guessing that the setup was the older style 3 wire one. The cables look reasonably old (house is 70s vintage, refurbed in the 80s, I suspect the cables may date from the refurb).

The kitchen jackpoint is used for our primary phone - an older 2.4GHz cordless - which I intend to replace very soon with something better suited to operating around a wireless network.

The bedroom jackpoint has nothing plugged into it but does have a phone extension cable daisy chained off it (I presume done by the previous owner). This cable goes on an epic journey around the house complete with a couple of extensions before arriving at a point on the lower level about a metre below the jackpoint. I had initially plugged a multifunction phone/fax/printer into the outlet of the cable.

I've had numerous adventures trying to remove the noise and started off by simplifying the amount of phone cable that was running around. I've then replaced both original jackpoints (both were corroded) with 2 cable ones (using just the red and white strands). And I've tidied up the daisy-chain birds-nest so that I had a much shorter length of phone cable running directly to a new jackpoint for the multifunciton machine.

This improved things a wee bit. I then realised that I was still using ADSL line filters and I'd forgotten to upgrade them when I upgraded my router to ADSL2+ a few months back. So I got a couple of ADSL2+ line filters and plugged them in. Things improved a bit more but I still had the line noise. I was reading the posts here and saw the recommendation for master splitters on ADSL2+ installations. How hard could it be I asked myself?

Anyway to cut a long story somewhat shorter I've attempted to install a master splitter about 3 times now over the last few days with varying degrees of success. I got some cat5e to run from the DSL output of the splitter to a new jackpoint for the router.I thought I'd update my phone wiring too to use Cat 5e while I was at it.

What I've found is that when I switch both jackpoints and my new dedicated DSL jackpoint to use the cat5e cables I get no DSL and no dialtone - no nothing. I suspected my gel connectors may have been bung so I've tried different ones with the same result.

If I revert back to using the old cables for the phone jackpoints and the cat 5e for the DSL jackpoint (still using the master filter) then I get the phones ok but no DSL.

I've tried a number of permutations to try and isolate where the issue is and now I'm reasonably confident that my system doesn't like cat 5 cable and I'm doomed to live in the 1970s forever.

I've pretty much come full circle now and just reverted back to using the original cabling and line filters on the jackpoint. Frankly I'm baffled and on the verge of paying someone to do it properly (shudder). I've checked my address against and seem to be in a wee island of VDSL - would that be an issue?

Many thanks for any help you can offer.

I would suggest getting a tech to come look at your wiring.

By the sounds of things you've reached the end of your knowledge in regards to phone wiring and it's time to call in the professionals :)

If you are in Auckland then coffeebaron can check it out. Otherwise in Wellington cyril7 can do it.

I also agree it does sound like a job for the pro's

As above, Auckland or Waikato, get in touch and I can sort it out.


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?

It does look like a problem connecting the Cat5 cable as you can get the other to work. Is the Cat5 cable solid conductor?

Hi Guys,

Thanks for the prompt feedback - The cat 5 is (as far as I know) just standard cat5e cable - I wasn't aware there are variations on it.

I think getting the pro's in sounds like a good idea (the wife will never let me hear the end of it) and I'll go back to the things I can actually do. Thanks again for the feedback.

The master filter caused an issue, not fixed it. Ah, the irony!
