insane: I'll throw something in here, if you are getting even slight packet loss you may still get respectable speeds locally but terrible speeds internationally, so even good national speeds may not tell the whole story.

I had just this problem a few weeks back after fiddling with some wireless networking settings, took a while to narrow the problem down given my good national results.

Ah this is a good point. What are the usual suspects for packet loss on a DSL connection?

BUBA: link between orcon/telecom, heavily shaped, will generally show peak time congestion, but be reasonable the rest of the time.

congested exchange: hard to differentiate from BUBA, some older equipment at chorus's end is still ATM, more likely if you're closeish to exchange and can only sync at ADSL1 speeds.

router memory leaks: http://tools.orcon.net.nz/notify/view.html?id=3590 is an example of it with Orcon.

wireless: you can do a ping to your adsl modem or a local computer on network if you enable ping through windows firewall and check for high pings / packet loss. don't do more than one ping at once to adsl modems though, as some have rate limiting and can give misleading results. (like if you ping from two connections at once 50% packet loss, but all packets get through fine)

bad ethernet cable: check for it like wireless, but will often force itself to 10 megabit etc.

high error count on adsl link: look at modem status, see if there are a lot of errors. if severe turning off interleaving can help.

congestion on the greater internet: if some international sites with similar pings are way better than others than this can be due to routing being different - sometimes routing can change from having a slightly different IP and give better/worse results.

Orcon support gone silent, I rang last week but the support guy not interested in linking the call to the old ticket number. Still pathetic speed outside NZ. I checked the packet loss issue using
London
pingtest.net packet loss 0%, ping 358ms, Jitter 149ms. service level F.
speedtest.net download 0.17mbs, upload 0.26mbs, ping 355ms.
NZ
pingtest.net packet loss 0%, ping 23ms, Jitter 8ms. service level A.
speedtest.net download 13.14mbs, upload 0.86mbs, ping 16ms.

I gave up today and called to close my account but they could not even do that, the system was down. I'll try again tomorrow.

grant_k: Sandy, I think you will be disappointed by the international bandwidth no matter which ISP you choose. I regularly download BBC programmes using iPlayer and with just one download happening, the highest speed I see is typically 400 - 500kBps. If I download two programmes at once, the total bandwidth consumed is close to 1Mbps. As you can see, the total bandwidth of your connection is available, it's just that you cannot access it via only one stream. This is why some people use Bit Torrents as they have many simultaneous downloads taking place.

YouTube is similarly affected as it is just one stream. Unless you want to view live TV it doesn't matter too much. This is the beauty of iPlayer which lets you download, rather than insisting on a live stream. I find it a much better approach for most programmes I want to watch.

fwiw i get 4 to 5 megabit with iplayer download.

it's curious that you're not getting significant packet loss but have such bad download speeds internationally. i'd try an https download to compare speeds.

from random google

https://test.kems.net/

looks like it has a speed test.

ok that's in kuwait,.. (it seemed fast though)

google isn't being very helpful.. but there are things like netalyzer too.. although it requires java.

These are the results from orcon's own diagnostics.

Speedtest Results:-
Auckland,NZ: 6362 / 798 (15ms)
Wellington, NZ: 4744 / 707 (314ms)
Sydney, AU: 2089 / 778 (323ms)
San Francisco, CA: 88 / 713 (477ms)
Maidenhead, UK: 68 / 534 (*ms)

Something dodgy going on at the Orcon throttling department.

cheers

Is your MTU and MSS correct?

i'd suspect a negative interaction with Orcon's HTTP proxy, hence why i thought a https speed test could be helpful.

I had exactly the same problem, but it was peak time only (4pm-midnight): dial-up speeds at peak time, back to 16mbps after midnight sharp. Wasted hours mostly on hold with useless Orcon support trying to solve this throttling bs, they kept logging the issue and closing it without resolving. I've been with Orcon for >7 years, but the current state of service is disgraceful and a total disaster. Currently counting the days until the disconnect notice period finishes and I'm being moved to new ISP, phew!

hmm, if it's actually that issue, that can be BUBA versus EUBA. with BUBA orcon have to pay extra per user to raise the bandwidth allocation per user. with EUBA they don't. but EUBA isn't supported on some legacy exchanges.

Although I thought orcon mostly fixed that issue a while back.

Although usually with that kind of congestion you'd have around 10 to 30 msec higher pings during the evening and around 5 to 10% packet loss. Speeds slow down internationally with even 1% packet loss though.

What plan are you on, whats your line attenuation and SNR? And whats your IP address?
