Hi there, and sorry if the following ia big wall of text;

I noticed my internet speed took a major dive in performance and did my own research plus logged a ticket with Telecom.  Im very close to an exchange and connect at 19Mbit on average, and performance is always been very good, a solid 1.7MB/s transfer speed.  Last month I did something like 13GB, ie, fairly light user.

Then I noticed online gaming started to lag and download speed was erractic.  Heres an interesting screen shot of my networking tab under Task Manager showing network performance during YouTube streaming speed test.




Assuming I got that image to display, you'll see almost a perfect square wave, it goes at 1.6MB/s for 20 seconds then 20KB/s for 10 seconds and so on.  Does this 24/7 regardless of the time so its not on-peak throttling.

Note during testing this is the only PC connected to the router via utp, no wireless, and tried different routers in case its internal switch was failing or something odd like that.

The Xtra helpdesk was polite and escalated the ticket to network systems who simply closed the ticket as it "working to specification". 

The gaming lag appears to come from lost packets as it hits the hard speed cut as if I leave tracerts running in a loop I can see them time out (usually where ae1-2.akbr4.global-gateway.net.nz should be).

So, does anyone else have this problem and has Telecom suddenly inforced stupid speed restrictions?  Should I open more tickets till I get something better than a "to spec" reply even thou WHAT spec is never mentioned.

Btw, downloads dont look as pretty as that square wave as they're not hitting Xtras local cache so are much slower to rise, so average performance is about half that again.  But it shows nicely whats happening....

Hi all,

Just an update, I've been working with someone in Telecom CTS who have made a variety of changes (line profile, euba-buba etc) without fixing the issue.  Next step I believe is as above and will be moved to a different port.  Will update again when that happens.

Chorus guy came out today.  Plugged in his tester into my line, saw a good 22Mbit sync rate, declared all to be perfect and it must be an ISP fault and went to leave and close the fault.  After pointing out to him that the whole point of his visit was to change the port Im on and as per his ticket info (he showed me his pda with ticket info) that it stated I always had a stable sync speed, he eventually went off to do so, but left 100% convinced it can not be a faulty port if sync was stable...

I just did some testing on some downloads from Rev3 (so international traffic) and....

Appears to be fixed.



Thats about a gigs worth of data in that capture to give it some perspective.

Its only been a couple of hours but I shall remain cautiously optimistic that it will stay fixed.


Thanks all for your efforts and feed back.
