Just as a follow-up to this... We were able to arrange a remote control session and it appears everything is working brilliantly.

- Rock stable ping to first remote hop with no packet loss
- DNS addresses were set correctly in the router
- ADSL line synced at about 10mbps
- Telecom speedtest over 9mbps
- Orcon Auckland based speedtest over 9mbps
- Popular youtube videos directed to local Google cache and showed downloads at over 9mbps
- Well seeded Linux torrent immediately jumped up to about 9mbps (This is international traffic)

Because of the intrusive nature of streaming video across a remote link back to me, I couldn't test the performance of traffic within any VPNs, or other streaming sites. Everything I did test however was essentially perfect - operated at or very near to line speed. This was during peak evening hours as well.

Cheers - N

Did we test on YouTube show the speed is just over 4MB, which is the lowest compared to other locations or ISP?

Thank you so much for your help yesterday. After the remote test and found out that nothing wrong with PC and router configuration, a master filter will be installed tomorrow morning and rewiring with cat 5e or 6 if possible within a reasonable cost range. Will keep updated after the job completion.

HI there - the youtube speedtest page didn't have lots of data for your individual site, so I opened the network interface monitor and loaded a large, popular HD video in youtube and observed the traffic actually coming in the interface. It showed a consistent approx 9mbps download.

I should point out that installing a master filter and redoing the wiring will not help if you continue to have issues with overseas streaming sites or VPNs... Your connection at the moment is a solid 10mbps connection and any issues with performance are due to factors well outside the adsl link from your router to the Telecom equipment.

That said, you may raise the 10mbps slightly for a better peak speed.

Cheers - N

Nice one Neil.. A superstar as always, and anyone would be hard pressed to argue with Neil saying he doesn't know what he's talking about. :)




I work for Spark, but as always my views are my own.

Thanks for your advice. It is my last resort, otherwise, I have to switch back to Vodafone (under the request from my wife). I hope to increase my overall broadband speed by improving my broadband line quality. Since the general speed is improved, then we may not face the current issue. 

Please do not think it in a wrong way, I am not here to blame Telecom or whatsoever. However, based on our user experience at home, the speed is slow in terms of what we usually use the internet for. We had with Vodafone for over 1 year because of minimum one year contract, we use VPN, streaming as usual and had no speed issue at all. It is because of such good speed with Vodafone, we all have used to it. 

I know most people think it is because I use VPN. The problem not only limit to Hulu Plus and Netfix, but also stop for buffering frequently when watching iTunes movies without VPN. 

I know the test results pointed against (or at least not support) what I said, but as you have seen, I have correctly configured my internet and PC, and I use top line gears.  In other words, nothing wrong from my end. 

After all, I have heard enough from my wife's complain.......I prefer to keep with Telecom, 500GB is so attractive (I do not like fair usage policy in terms of unlimited data), so give a last try to install a master filter (rewiring if possible) would not harm anyway. In the meantime, Telecom support will update with me by the end of this week about their tests from their end. So finger cross the speed is fine & acceptable by my wife by the end of this week. 

Will updated once completion & will post some test results in case switching back to Vodafone.

Thank you so much for everyone's help especially from Neil.

I am keen to look at the results from Telecom tests ... 

I have been following this thread because I kind of have a similar issue, specifically with Youtube and Extabit downloads. My neighbor on Vodafone gets 10 times faster download speeds from the same links I am having issues or slowness with. 

Interestingly Telecom was real fast until August this year, and dramatically slowed down just after August, and I have done line tests, changed all filters, swapped modems, you name it - i have tried :) 

In that aspect, I have to say - my speeds are brilliant on other sites and downloads such as Microsoft. I get an overall 10mbps download and 0.8 upload as my speed test results.
My modem (given by telecom) says i am connected to exchange at 14mbps

The master filter is installed, but I notice the line speed is actually slowed compared to before without master filter. Is it normal? OR it is faulty installation?

Here is the before without master filter installed

.


The below is after installing the master filter

Sorry, as I suggested, the ADSL line was already operating absolutely as expected with no issues. In cases where there's nothing wrong with the existing wiring there's little to nothing to be gained from replacing it.

The difference is essentially nothing anyway - I would imagine if you rebooted the router a few times you would get different values - some closer to the original - perhaps marginally higher...

Are you using Teleom’s DNS? 
If not, that might explain why youtube is having issues since you won’t be able to use Telecom’s youtube cache on a non-Telecom DNS

So what VPN service are you using? Sounds like Vodafone may have a better route to this particular VPN providers servers.

Anyone know if Apple still uses Akamai for delivering itunes movies? That should be similar performance to Vodafone as both have Akamai caches if you are using Telecom DNS and not using a VPN as traffic will be directed to local caches.

Apple uses Akamai for iTunes distribution. If the OP uses a VPN then the connection WILL NOT be to the closes cache in New Zealand, but probably somewhere in the USA.

Also if not using Telecom's own DNS then there'll be no access to local YouTube cache.

All in all using a VPN in this case makes things harder. It's ok for some services that are only available in the USA, but not for services with local caches.

Exactly, should only selectively VPN certain devices at certain times (when watching netflix or hulu) and turn it off the rest of the time. Smarter VPN services like Astrill have addon's for DD-WRT and Tomato that can do this.

Youtube should not be a problem if you are using Telecom DNS servers and not using a VPN.

Looks like Extabit servers are on leaseweb in Amsterdam so that's probably an upstream routing or transit issue.

Thanks. Tried few times of rebooting, but the speed is the same, which is lower than before. Anyway, it is not a big deal. 

However, I am not going to dig holes and spend lots of money for rewiring. it is not helpful in this circumstance. 

Update from Telecom support, The interleaving on my line is disabled. I did speedtest.telecom.co.nz a few times now showing that the Ping reduced from usual 24 to 9 or 10, the speed is no significant difference. I tried to download and streaming, it seems the problem is solved now. The average download speed for my needed files are pretty good, which is in average 500kbps and can go up to about 800kbps. I will keep monitoring for few days to confirm the reliability.
