If the change was just a DSLAM setting change then not a lot is likely to change, the only option is to move you back to the cabinet, this requires jumper changes (along with service setup) at the exchange and cabinet, so a truck must roll.

"A truck must roll" sounds like the type of action I'm-a lookin' for! ;-)

I would imagine that it ought to be in their interests to make it happen, because before getting my house rewired, I'll try switching to Xtra first. I don't know if that's what the rest of you would do, but it seems easier than getting a comms tech in to fix something that might not even be an issue...

Hi, agree with that, first priority is to get moved to the cabinet either on Orcon or move to Telecom Retail (Xtra does not exisit anymore as a brand) and depending on the results look at your house wiring, but from my experience most house wiring has a modest to significant impact on ultimate speed.

Thanks for all the advice Cyril. I notice in another thread you talk fairly knowledgeably about this stuff (and the way you explain it in that thread helps me understand more about the impact it has.

To that end, would you recommend I talk to Chorus about getting it done? Does Chorus even accept calls from the public, for that matter? And, if not -- any recommendations on who to speak to?

I will obviously pursue the cabinet vs LLU issue first, but my eyes are opened on the wiring now too.

Cheers!

Sorry, as an end user there's no avenue to talk directly to Chorus... Your retail ISP should handle all communications with upstream suppliers (Chorus or Telecom Wholesale)

Hi as Neil says your contact is via your ISP who will contract Chorus to do this for you. Alternatively if you are modestly practical it is not that hard to do and I can assist suppling parts if needed, if you want to go down this route then a bit of an explanation of what the current phone wiring layout is will help. Beyond that you will find data cablers or data capable sparkies in the yellow pages may provide a keener price to do the job than Chorus.

Cheers guys this is great advice and I appreciate it. After I sort out the cabinet vs LLU stuff, I'll have a look in the phone book (ha, doesn't that sound kind of quaint, all of a sudden!?)

I'll continue to post my results in here, as I'm sure other people will want the same information at some time or another.

Hi all,

So when I got home, I got the same kind of performance (not as bad as that low point speedtest I posted earlier in the thread, but still ~2mbs), so whatever Orcon did didn't make a jot of difference.

Whilst I was at home, I grabbed some stats off the router. Hoping these are the right kind of stats for what you guys typically decipher? Wondering if this might shed any further light.

Thanks for being a great community!

Without getting into the details it confirms that your physical connect speed is a current bottleneck so the midspan injection from a cabinet and the fact you're served from an exchange are definitely having an impact. It's not possible to be 100% certain that changing to a Telecom Wholesale type connection served from the cabinet will fix your issue, but it's probably ok to say that it's 95% certain :-)

Hi, as you can see from the results your line attenuation (which is probably artificially inflated due to interference) at 22dB should be good for a sync rate of 15-16Mb/s not the 2.5Mb/s you are getting, so as per my previous advise.

So right now your line is connected to the new cabinet but doesn't terminate there, it passes through back to the exchange where it terminates on Orcon gear.

That situation pretty much always leads to a massive performance problem. Ideally they should have never put you on their gear in the exchange if they knew a cabinet was going in your area (which they would have).

We have seen similar posts about this from people on Vodafone Red, Orcon+ and other LLU connections many times on Geekzone.

Right now they should be definitely offering to be move your connection off their own gear in the exchange to terminate on the closer gear in the cabinet, no questions asked.

If the above is going to cost you more per month or they are dillydallying you around, it's probably worth reviewing other ISP's.

I had an interesting experience today looking at a Orcon connection with sync stats of ~900kbps and around 60dB attenuation. The Telecom Wholesale prequal check shows attenuation of 7dBm and speeds of around 15.5 - 15.9 Mb/s.

It shows the sort of impact midspan injection has..

Thanks all for your help.

After 16 minutes on hold -- which seems like a lifetime when they play the same two songs over and over again, only to stop and restart after the "Thanks for holding, check out our new improved FAQ on Orcon.net.nz!" -- I talked to a tech who:

[1] did a remote speed test (the first time anyone from Orcon's ever done it)
[2] concurred it was slow
[3] agreed (when I talked about your advice) that it WOULD be a cabinetization issue
[4] said I need to run their diagnostic tool and send the results before she could progress the 'fault'

So, albeit slowly, we are definitely progressing here, and it's only thanks to the answers I got here that I've felt confident enough to push the matter and not settle for the "buy a new router" answer from when I first raised this with them in June.

After sending through this stuff, if they stall me too much longer, I wonder whether a change to Telecom Retail -- and asking for proper wiring at the same time -- might be an idea!

Hi, seems like you are moving in the right direction, just on the point of the wiring, over the next year on phone and BB you will spend around $1200, so to spend 10-15% of that on ensuring you will get the most out of a BB connection that will be with you for at least the next 5-10yrs is pretty good value.

Like most of us you probably spend a similar amount on petrol each year (if not more) yet you dont complain about putting the good oil in once or twice a year.
