Up Stream   828 (Kbps.) Down Stream   16235 (Kbps.)

Noise Margin   13 dB

Attenuation    3 dB
It's actually increased since they moved me to a new port on the cabinet.

I get pages loading for ages and ages, pages loading with out the graphical bits and I can't download anything.

tried a wee game (Amnesia) recently. No go. They company gave me 3 separate links to try - none go further than 77MB before crapping out.

Tried:
ASUS modem

Netgear Modem

Dynalink modem.

ASUS brand new.

Tried my PC running Win7 and also an HP netbook running XP.

Tried various DNS servers.

It's not my end.

Anyway I rang them again today and they said they'd already changed ports (hmmm, noise, attentuation now higher) and the new theory is I am too close to the cabinet and my modems can't handle it so they want me to use their Thompson modem.

OK, I'll try.

However I seriously doubt modem number 4 will make a difference.

This has been going on since I moved here and Telecom connected me on 8th November.

Doesn't matter what time/day it is, doesn't matter what website either - it's random.

Speed is great, doesn't drop connection either. No noise on the line.

Well speed would be great if I didn't have to wait 10 years for a page to load.........

Any intelligent ideas out there? If the tier 2 techs don't know and that's what tech number 2 said, then I sure don't.

What is a typical traceroute and ping using the Telecom DNS servers?

Using overseas DNS servers such as OpenDNS, Google etc will cause a large numbers of problems if you are located in NZ and is not recommended. It will cause issues like this such as slow page loads and downloads due to the fact it can't cope with local CDN's and caches.

From another forum:

Tried latency tests to different places?

alien.xtra.co.nz

dnsc1.xtra.co.nz

ns1.maxnet.net.nz

trademe.co.nz

gpforums.co.nz ( :D? )

do they all give you back similarly bad results?

perhaps do a tracert on some of those as well if some are ok and some are bad :)

---

Ping:

1)Timed out

2)Timed out

3)17ms

4)16ms

5)17ms

Tracert

1)17ms to Jetstream hop 2, timed out hop 3, timed out hop 7, 8, 9, failed.

3)71 ms to Jetstream hop 2, ok (17ms average) till hop 9 then 201ms at maxnet, but it got there.

5)17ms to Jetstream hop 2 and all the way via Telstra and Maxnet, all around 17ms.

But if I do this again sometime it won't necessarily give the same results. I did it for 3 days to various sites here and overseas for them, random as I say.

So.

Now Gpforums loaded OK just now.

Trademe loading, loading, loading again.

Sometimes it does, sometimes it doesn't, sooner or later they all do - like if I go away for a bit, come back and try again I may get loading for ages with GPForums again. As a for instance.

Beats me....

------------------------

Those latencies look fine to me, I'd say it's more along the lines of the proxy issues that crop up every now and then. The hops that time out are irrelevant as the device most likely blocks icmp

Your best bet is to note the time and site which gets stuck loading and PM ptinson with the details, or you can do what I did and get a static ip (free on pro) and ask to be put on the proxy bypass list meaning you don't go through their failure of a web cache farm.

---

--------------------------

If it were being to close to the cabinet, your results would be consistant across the board - so it's obviously not that and your tracert's look all good.

try running some long pings like

ping trademe.co.nz -n 1000 >> C:\pingtest.txt

and then check the file for inconsistancies.

99% says it will be pretty consistant, which still leads to be a network issue - as opposed to a physical line or cabinet problem.

---

-----------------------------------------------

Does your web page load like stop at half way through? (kinda like whole pages are broken up in pieces?)

You using custom DNS server?

If all above answer is YES, try remove custom DNS server and use Telecom Default DNS, also you might want to clear your browser catch.

-----------------------------------

They've had me do that and yes they are consistent.

-=------------------------------------

Clear my cache? Yesterday I cleared the entire PC - did a fresh reinstall and tried IE and FF before doing anything other than windows and drivers.

Then finished off my install and tweaks and tried again.

No difference whatever I do at my end.

As I'd said anyway, I tried another PC before.

I tried IE, Chrome and FF. Went back to FF3.5 after the new install too.

Tried auto DNS< Googles, OpenDNS and Xtras.

Makes no difference.

Sometimes pages won't load and yes sometimes they load half-assed like you say.

What plan are you on? Does your plan have overage charging or does it throttle if you go over your cap?

It's quite possible that if the plan has hit it's cap and been slowed that you'll see slow page loading but have pings often show normal latency.

Dude - you haven't provided these details anywhere in the thread and the symptoms match closely. You've got 38 posts so while you have a fair amount of info in your first post and have clearly tried some troubleshooting yourself, you're not an old hand around here at least.

I've been involved in some of the more subtle performance issues and investigations at Telecom - I've seen pretty much all of the possible issues. You need to remember that most issues still come down to in home wiring or a misunderstanding of what the performance should be.

I'm happy to help (although I am not front line helpdesk staff) because I am passionate about our BB performance, but I'm not prepared to put up with these sort of put downs.

You have been permanently capped lol.
I'm afraid there is not fix, you'll just have to move houses.

I have: This has been going on since I moved here and Telecom connected me on 8th November.

If it was something silly like over data, it would have been reset. I mentioned Telecom moved me to another port too - so you see, even if I was thick and hadn't done all the usual tests, they would have made me do that when I rang them.

It does not drop connection.
Speed is good.
There is no line noise.

In fact I don't know if lag is the right description really. However believe me I have done everything at my end.
I'm a PC tech (yes just a lowly tech, not a network engineer or such) so I know how to troubleshoot PCs and modems.
Husband used to work for Telecom a long time ago so he can test lines and jackpoints.
There's no interference on it.

What I have done:
Unplugged the only phone.
CHange it's filter (i have loads, new old, mostly Tlinks)
I use a Win7 PC - I also tried an HP netbook running XP - this PC had never been on the net before - in fact had just been taken out of it's box to be used at my sons workplace.

Tried IE, FF, Chrome.
3.6 FF, 3.5 FF, 3.0 FF.
IE 7, IE 8.

Tried an ASUS modem, a netgear modem (my sons), and recently a Dynalink modem.

Reinstalled Win7 (not really cause of this problem) yesterday. Tried it with just the new install and IE before adding the rest of my SW, tried again after adding all my AV, apps and tweaks back.

Stumbleupon fails often, seek fails often, trademe, Stuff, NZHerald.
It usually just says loading for ages. Sometimes it may load the page without all the graphical bits.
Refreshing the page - after I do it a load of times eventually gets there. Sometimes it doesn't and I give up and go away till later.

I don't download much - mostly just AV updates and such like. Mostly that has been ok, it I have been trying to download a wee game and I can't, It fails at various points, yesterday at about 8%.

The game people gave me 3 different links to try, none work. IE says Connection lost, Chrome just exits, FF said um, not connection lost, file could not be saved because location unavailable or something along those lines.

My plan is 10GB, I use maybe 2GB usually in a month.

This began 8th November - the day Telecom connected me at this new house.
It is not spefici to time of day, website or any other traffic type cause that I can see.

It may be my imagination but since they moved me to another port (24th Dec) refreshing the page works sooner than before. That is, I may have to try that 4 or 5 times instead of 10 or 11? Or maybe thats just luck? Not sure.

With Stumbleupon - when you click one of the articles - it has a kind if, I guess redirect URL. If I take the stumbleupon part out and then refresh I have more luck refreshing to get it there than just refreshing with it as is.

Have done all the pings and tracerts Telecom have asked, they are consistent.
here's an example:
alien.xtra.co.nz

dnsc1.xtra.co.nz

ns1.maxnet.net.nz

trademe.co.nz

gpforums.co.nz
---

Ping:

1)Timed out

2)Timed out

3)17ms

4)16ms

5)17ms

Tracert

1)17ms to Jetstream hop 2, timed out hop 3, timed out hop 7, 8, 9, failed.

3)71 ms to Jetstream hop 2, ok (17ms average) till hop 9 then 201ms at maxnet, but it got there.

5)17ms to Jetstream hop 2 and all the way via Telstra and Maxnet, all around 17ms.

Ok... a couple more questions...

What result does the speedtest here ( http://speedtest.telecom.co.nz/ ) give you? Not any other speedtest please - just this one. I know where this server is and for Telecom retail customers it should give good results.

Do you have a static IP address?

Do you have the router set to grab the DNS server records from the PPP session or have you hard coded in some DNS servers?

On your PC, what DNS servers do you have configured and how is the IP address allocated? For the purposes of troubleshooting, you should allow the ADSL router to assign the IP address via DHCP and assign itself as a DNS server.
