Hi Guys,

Just trying to help out a family member who is with Orcon and been having no end of trouble.

When I started to look at his connection I immediately noticed a few things:

(a) His house wiring was terrible (excess lengths of cable under the house etc (using that flat crapy cable)
(b) lots of Timeouts on a C:\ping www.google.co.nz -n 1000 (only about 90% of packets came back)
(c) Fairly low sync speed considering ADSL2+ and distance from exchange (about 3.5-4km)

So in order to isolate the fault the wires were cut at the Demarc and wired the modem in directly to the street. I really thought this would make a huge difference, but alas no - there was still heaps of ping drop outs, and the sync speed didnt go up - > this implies the problem lies between the Demarc and the exchange?

Orcons initial response was to up the SNR Margin to 12 - which I hate ISP's doing - thats just masking the poor connection by slowing us down!

So after many phone calls to Orcon they finally agree to send out a Chorus tech. Now I wasnt around when he came but I rang him afterwards. He said he spent about an hour at the house and had no disconnections and so he left. He said he was paid by the hour and could not afford to spend any more time on it. He went on to say some of the Chorus techs are not paid by the hour and to try to get one of them onto it!!!

Ping statistics for 66.102.7.99:
Packets: Sent = 1000, Received = 975, Lost = 25 (2% loss),
Approximate round trip times in milli-seconds:
Minimum = 162ms, Maximum = 2102ms, Average = 175ms

Here is some screen shots from DMT tool - but I really dont know how to interpret them - perhaps someone else can help here:

Cheers

-Al
PS: Anyone know who the best Chorus ADSL techs are in Auckland?

Looks fine to me. 5364 kbps is pretty decent for 48 dB attenuation... I used to get that on 42 dB attenuation. Don't know why Orcon would change the SNR margin if there were no complaints of poor connection stability, but then 12 dB is standard. DMT Tool might be able to lower it if your family member wants more speed and the modem supports it, although going below 8 dB does tend to push the stability a bit.

2% packetloss to the US is nothing unusual for Orcon, even if they are only ICMP ping packets of default size. Packetloss is particularly bad during peak hours due to congestion on Orcon's oversubscribed international links. In any case, it has nothing to do with anything between the modem and the exchange.

What exactly has your family member been complaining about? If it's poor international performance during peak hours, then he's basically in the same boat as every other Orcon customer.

5.2Mb/1Mb @ 48dB is definitely acceptable.

Well another unusual thing I have noticed is the SNR margin seems to flucuate the longer the modem is on, and generally in a downward trend. Sometime it hits zero then goes to a crazy figure like 236212.

Sometimes it can take half a minute to load a webpage etc etc etc.

Can I recommend that you force the modem back to ADSL1, with a line length over 3.5km there is no speed advantage in ADSL2+ and by reverting to ADSL1 you circumvent any issues that ADLS2 does with regard to dynamic power control that could be why you get a spiralling S/N issue.

Beyond that I think at 48dB and 5Mb/s you are doing pretty good.

Can this application be used on any ADSL router? I have a Dynalink RTA 1320, yet when I try to connect, It doesn't work!

Yeah but I still get lost packts on the way to the orcon dns server!!! I can accept it might be reasonable to loose a few packets on the way to google - but Orcons own DNS server.....

Do you get packetloss to the DNS server during peak hours, or both peak and off-peak? Either way it would be somewhat unusual... and worth sending a traceroute to Orcon so that they can check the relevant routers.
