Hi all, I have just swapped from an ADSL 2+ area to an ADSL 1 area. I have been on the phone to Telstra every couple of days for the last couple of months as in the evenings I get speeds of between .5 and .6 Mb/s down, sometimes dipping to .1Mb/s. Additionally my ping will chop from around 100ms to NZ, to upwards of 6000 for periods of 10-20 minutes.

Telstra contacted Chorus a few weeks ago, and Chorus stated that there was no congestion, however Telstra have now just called me back and said that the exchange is overloaded and there is nothing they can do about it. My neighbours have stated that the internet is slow around here, but none of them seem to experience the speeds I do.

Am I expecting too much from an ADSL 1 line or are these kind of results typical of a busy ADSL 1 exchange? The most frustrating part is the horrendous ping as it means it is not possible to use Skype and online games.

Should I try another ISP?

Tracert and speedtest below. Thanks in advance.

Please post your line stats (you can find them in your modem's control panel) and also paste in the contents of the rightmost column after entering your address into SAT.

What are you ADSL modem sync stats?

I assume the tests you are doing are being done over a cabled Ethernet connection, and not WiFi?

Approx where are you located now?

Have you moved to a rural location and now you are connected to a Conklin?

Unfortunately my address is no found on the Chorus website. I am on the Ohakea Air Force base in the Manawatu. If I do a search on a nearby Bulls address, it shows the base without a colour code.

Yep, have done tests with everything pulled out of every jack point except the modem. Wifi turned off, only 1 desktop connected to the modem via ethernet and no change.

On the Ohakea Air Force base in the Manawatu. I am unsure whether I am connected to a Conklin as I am not sure what that is.

You're on the Sanson exchange, if you search for that then it shows up orange. However, that doesn't help you much. The eastern half of the base is covered by Vodafone "RBI" wireless at the moment, but the western half isn't due until later (more than a year away). Coverage map is here.

Ohakea has it's own MDF on base there but it is only a DSLAM with ATM back haul (as far as I remember) to the Sanson (SN) exchange which has an ethernet back haul to Palmy. I would say because it has very limited back haul and with the people using it probably all coming to use it at around the same time (I am just purely speculating about your schedules) this is why you are seeing such high latency.
The barracks have only single jack points from what I remember so wiring shouldn't be an issue. Also the backbone cabling is all new-ish grease filled underground around the place so I don't see that being an issue either.

The base did get an 'upgrade' about a year ago but I am not sure whether it was actually an upgrade all they just simply relocated all the comms equipment. All I know is when I came to hook a line up one day the MDF wasn't where it used to be.

I live in the houses on the North side of the base. I am kind of hoping home wiring is the issue so I can hit the AF up to get it fixed, however Telstra didnt seem to think it was a problem (however noone has been out to take a look).

One guy up the road said that his latency never goes above 200ms to NZ, and another said that he has never seen speed slower than 1MB/s (they are both with Telecom) which makes me think that although the exchange is busy, I should be getting better performance than I am.

Any ideas guys? I have pretty much conceded to the fact I will get slow speeds, but is the terrible ping to be expected as well?

Any merit in getting my wiring changed or swapping ISPs?

The Chorus main Frame/cabinet on the base hasnt moved - just the defence PABX switch site was moved to its own building (near the old gate/guard house)

Bulls Exchange is not connected to the base and neither is Sanson Exchange  (It was a exchange site in its own right but has now been incorperated into Sanson Exchange Area as a cabineted areas but actualy isnt connected to it)

The chorus ATM on base actualy goes back to Palmerston North via fibre

Anyway the base houses are connected to copper loop cableing similar to regular streets - from those grey pillars on every 2nd boundary (most of these were recabled in the 1990s) - but in alot of cases the wireing in the houses is that from the 1950s

a DSL filter and a rewire to a dedicated jack point should help speed your world up

Changing ISP's would only help if the issue was BUBA handover congestion.

Hi Kaiza, I've had a chat to our broadband guys and they believe that the problem is as others here have said and a result of the exchange you're on and possibly with the premises wiring. If you PM me with your account number I can ask them to have a further look into it for you.

Cheers, Gary
