voy1d: Yup, waiting for someone at Vodafone to answer the phone because there has to be something bigger at play.

They were done over wifi (I don't own a network cable) and when everything was fine (prior to 6pm) I had good speeds.

In that case, you need to get an app or program that will show you how many other wifi APs are around, what channels they're on and what strength they're at. But unless you're out in the middle of nowhere with no one else around, you need to test with wired ethernet. (Your wifi could be getting congested because everyone else is on their wifi at the same time)

(Unless you're on 5ghz 802.11n/ac and no one else is)

No idea for Wellington region someone here on Geekzone should be able to advise someone,

WiFi speed can be impacted by so many other things but as the Attenuation has climbed again it's not WiFi related or ISP

Will see what happens when Vodafone decide to answer the phone...

They will get you to do basic fault checking and come to the conclusion over time and many tests you have a wiring issue, The answer is in the stats of the modem,

Did you review the blog post I linked off to on page 1 of this thread?

Draytek Vigor 120
Down Speed: 2.39 Mbps
Up Speed: .39 Mbps
SNR: 12
Attenuation: 31

Your attenuation simply should never change (well, perhaps 0.5dB at most). If it's moving between 32 down to 23 and back up, there is a physical wiring fault somewhere. You will never have a stable connection with any ISP until this is sorted.

See if there is a pattern to this attenuation change - e.g. it increases every time it rains or something similar.

And in that case I'll request another Chorus tech, because whatever the last guy did worked...

If it's an intermittent fault, may have been co-incidence it got better while Chorus were there... Just something to keep in mind.

Chorus look after the network up to the ETP pass this and into the house is the house owners network, Chorus did not resolve the issue as it's back again,

I only started looking into it yesterday afternoon (and the weather has been rubbish since midday yesterday) and a fix was put in around 4.45 this afternoon which solved it, but after 6pm I have noticed its dived again.

Either way the Chorus guy managed to improve it out of sight which would indicate to me that whilst there may be a wiring problem it might need more work to resolve.

The only reason that Chorus even sent a tech is because their faults team identified my neighbours all getting 10 Mbps + (as advised by the friendly tech) so yes there could be something isolated to my apartment, but since I'm renting I want to avoid any unnecessary expenditure.

I didn't think Attenuation should move in the way it has, but will keep an eye on it.

Fix was not put in around 4:45pm today as the issue is happening now, Your neighbours I suspect have better quality house wiring,

It could be a faulty jack point the modem is getting plugged into, Such a small fault in house wiring can send a xDSL connection down the tube,

The house wiring needs to be checked out end to end saying all the time that Chorus fixed the issue today is not correct or you would not be having the same issue now

johnr: Yes as advised I would see about getting a master filter install and the house wiring checked out by an expert

Would you be able to suggest an "expert" then, because I have no idea who the heck to contact.

I'm sorry but my patience is really starting to wear thin...

Phone wiring is a tricky thing. Statistically speaking internal house wiring is the biggest cause of speed related issues but the internal wiring is owned by the homeowner, and it's their responsibility to maintain it. If you buy a fridge from Harvey Norman you don't expect them to come and install a new power socket for free..

If you pay wiring maintenance then a Chorus technician can visit and fix any obviously faults, but it's not their job to rewire the house or make any major changes. If you want the optimum broadband connection you need either a master filter or a modem connected directly to the demark if you only have a naked connection. Your ISP can arrange for Chorus to do this for $199.

The issue could be outside your property, in which case it'll just go through the normal fault process. Getting inpatient isn't going to make the wheels turn any faster.

Thanks Steve,

I fully get what your saying, and that is why I'm going to see if I can get Chorus to send a tech to investigate further. If they say the fault is internal that is fine, but I'm getting the impression that I should just get the house rewired and/or have a master filter installed as the first step - which as I've been burnt by doing this I'm somewhat hesitant to be do this as a first step (see below)

I guess my past experience with a similar situation was after Chorus insisted that the fault was in my house, we had it rewired (at significant cost) and then it was identified the line card at the exchange was actually faulty. So my faith in the situation of "the house must be the issue"

Anyways, the tech is getting sent back out again (and if he says a master filter needs to be installed I'll happily install one)

I'm not insisting I'm a special case and that the line must be the issue but the tech found a fault, remedied it and it appears to have reoccurred (or could just be a huge coincidence)

Thank you all for the assistance and apologies if I've seemed ungrateful for any advice given.

I've just had the tech revisit and he has isolated the issue as the terminals on the module being corroded. There is a leak in the service cabinet and water was dripping onto the terminals - the tech has cleaned the modules for my line and two other lines which were affected. I've emailed the property manager to pass onto the body corp to make sure that something is put over to protect the module from this occurring in the future.

Now connected back at 14 Mbps.

That would definitely explain the attenuation bouncing around - I take it it's back down in the low 20s now?
