badcam - your issue seems to be completely different to the one in this thread, perhaps yours is due to an overloaded exchange.

This is rather symptomatic of congestion on the exchange. I guess to prove one way or an other, talk nice to a neighbour on a different ISP and do some comparison tests, particularly at night.

Bad Cam, the issue with XNet has always only been that your speed gets limited to the same as a plan less than what you are on, i.e. if you are on FS/FS then you would randomly go to FS/128k or 512k/128k. They thought they got it fixed, but then discovered that sometimes the upload speed is still reduced to 128k. It has always been that speed is restored by restarting the modem or by dropping the line (unplug and plug back in). It has never been about speed fluctuations. Going through the data you've posted, I would say maybe the modem is faulty (it happens) or it is exchange congestion. Since your modem stats show no errors, I would guess modem congestion which is also reflected in the varying maximum pause. The time you had very good speed you had a maximum pause of 13ms and an average of 1ms which is really good.

On 29/10/06 you've posted that you use Skype a lot (http://www.geekzone.co.nz/forums.asp?ForumId=49&TopicId=9999). Do you quit Skype before doing speed tests? In the post your PC was on a wireless connection; are you doing speed tests over a wireless connection? Skype uses bandwidth even when you are not and wireless networking has hugely varying performance. In the post you also were running double NAT, is that now resolved?

THanks Y'all.

Maybe I misread maverick's initial comments "The recent issue where certain customers DSL connections were intermittently falling back to a lower speeds should now hopefully be resolved". I don't believe for one minute that it's an overloaded exchange. If that were the case the "congestion" would be more prevalent in the evenings and perhaps weekends.

I don't believe that the DSL should fluctuate this much. It's not my modem as I have had this checked at my parents place and it's performance there is consistent with how their modem's results.

I do use Skype and still do. Skype doesn' use more than 1kbps up or down when in idle mode. MAX. Yes, I do turn Skype off whne running these tests as do I make sure that all other tabs on FF etc are closed. Yadda yadda yadda.

There are other people on this forum expressing concerns about the same problem that I am experiencing. I am not alone here.
I am doing tests over a wireless connection on my laptop and also via the ethernet port for my Desktop. I get the same results.

I no longer have the DSE1169 nor the USR8054. I'm using a Dynalink RTA1046VW

The router is fine. I've recently shifted about 1/2km up the road at the same time moving from Xtra to Xnet. Perhaps I've shifted enchanges as well. I wish I knew. I do know that I never experienced these issues when I was with Xtra. I had the same. My Router reported the same line rates (up/down) as I am getting now.

I am not getting the same amount of satisfaction from using Xnet as i was with Xtra. I expected otherwise. I don't wish to go back to Xtra and have no intention, but I also don't expect to be cajoled into believing that this issue is something I should put up with.

I don't do torrents often myself (only when I'm desperate to try a new linux distro) but I like my VOIP. Xnet refuse to let me use my existing router (which is ATA capable) for VOIP on their system as they only "recommend" Linksys. This is another issue though.

Speed test statistics - Over my wireless and no skype.
---------------------
Download speed: 1301696 bps
Upload speed: 727808 bps
Quality of service: 71 %
Download test type: socket
Upload test type: socket
Maximum download pause: 753 ms
Average download pause: 9 ms
Minimum round trip time to server: 71 ms
Average round trip time to server: 138 ms

Anyway. Thanks for your replies.

Are the results being taken from Xnet's speedtest?

XNet specifying what VoIP equipment works (well) on their net work is not an issue, it is a requirement which has been discussed many times. And they are not the only company in the world doing so, however there are few companies that will unlock the hardware when you leave their service. Telecom also specify what can be connected to their phone network, only Telepermit certified devices.

My speed is very stable on 3.6Mbps. It never varies more than about 300k. You are connected on ADSL1. Perhaps the old equipment in the exchange is faulty. When you moved up the road and your ADSL got changed over they could have plugged you into a faulty port. Or the wiring at (or to) the new place might be faulty. Or you might have a faulty ADSL filter or something.

Ok, I've finished bidding on TradeMe while everyone else is sleeping so I'll go to sleep now...

Hi Niel

I have naked DSL, so the equipment should be new ie Xnet's own equipment. Ans, yes I'm using xnets speedtest, at thier request:

http://speedtest.xport.co.nz/

M\Now, I know that I can achieve fantastic speeds on this DSL connection. But, it changes so dramatically. I never experienced that with Xtra. If I could just get some consistancy at a reasonable speed then I would be happy. Right now, I never know what I'm going to get. If only it wouldn't vary by more than 300K, I'd be fine with that, and of course plus 3.6Mbps.

Anyway. I'll jsut keep calling Xnet every few days in the hope that someone works out what the real cause is.

Thanks.

It is NOT Xnet's equipment; it is Telecom's.

Telecom have one set of DSLAM/ISAM gear for their customers, and all 3rd party ISPs (connected via UBS) are on a different set.

It sounds to me as though your ISAM port is faulty. Your speed fluctuation may be cured simply by a Port Reset, or your port may need replacing.

Either way, it's Telecom who have to do the work, because it's their equipment. But you will have to work through Xnet because they are your ISP. Xnet have some great technical people, and I'm sure they will do their very best to get this issue sorted for you.

BadCam: Hi Niel

Also do some caparison tests at the same time on the NZ servers @ https://www.speedtest.net/
Generally the results will be comparable, but if you see quit varied results, I.E. speedtest.net be much quicker than speedtest.xport.co.nz then that would indicate a issue with xnet's speed test. I have seen some variation there from time to time. Also, what exchange are you on?

Coffebaron:

I've tried many of the tests. NZDSL and all the ones they link to, Speedtest.net, both of Xnet's etc. They all give similar results.

grantk:

and all 3rd party ISPs (connected via UBS) are on a different set.

- So who's equipment would this be?

Yes. I know it's Telecom's network, but Xnet have their equipment (as far as I understand) in the exchanges for Naked DSL. It's still Xnet's problem to sort out.

I will, as you've advised speak once again with Xnet. I'll ask to to do a port reset or as you've suggested see if the port needs replacing.
Thanks.

Xnet don't have any equipment at the exchanges.
They only have their routing / monitoring equipment at their datacenter (or whatever you want to call it)

Equipment at the exchanges isn't Naked DSL, but the unbundling. Which, at the moment, hasn't gone very far and Xnet haven't really participated in, since it'd early days.

Any progress on fixing the upstream speed throttling issue yet?

Hi,

I'm a new Xnet Fusion customer and I am experiencing the upstream throttling problem.
It's happened to me about 4 times over the last week. A modem/router reboot always fixes it.
Is this an issue that is still being worked on?

Cheers,
Nigel.

There is a difference between Naked DSL and LLU. However WorldxChange are still your point of contact.

Really?

This used to be the situation a couple of years ago, according to an article writtten by one of the technology journos that I saw somewhere. There were also various reports I read which stated that in some cases, customers had churned from Xtra to another ISP and as a consequence they could not be connected because of a lack of 3rd party DSLAM ports at that particular exchange.

CM -- I take it from your comment that this is no longer so?
