Windows XP Pro, 1GB Ram, standard firewall (on)
Currently no antivirus for testing purposes. (Was running bitdefender Internet Security 2012)

Slingshot Navigator Pack

Modem: Netgear DGND3700 - latest firmware
ADSL Link                Downstream    Upstream
Connection Speed    14617 kbps    1158 kbps
Line Attenuation        26.0 db          15.1 db
Noise Margin             6.4 db            6.0 db

New telco wiring to street. (underground via conduit during renovations)
CAT6E From demarcation point on side of house. I have split this into two phone lines. Both filtered.
Nothing else attached. I can guarantee this as I have rewired the house during renovations.

Testing carried out via speedtest.net and Slingshot tools.

Speedtest.net…
Down:
Speed either good or bad with very little in between.
Either 12.0-12.5 Mb/s or 1.5-3.0Mb/s.
Mainly see issues after 4.00.pm
Last couple of days have shown very poor measurements even within NZ. (National Servers)
This seems to have changed this evening (25/03/2012 20:25) with all NZ servers on speedtest.net now giving good up/down.

Testing against Brisbane(internode) either 12.0-12.5 Mb/s or 1.5-3.0Mb/s. Depending on what time of the day it is.

Up: very stable on all tests at 0.9 - 0.95 Mb/s

Local test via slingshot page very stable at 12-12.5 Mb/s (always)

Latest speed test to Brisbane

Summary: Highs during day, lows at evening. 4.00.pm onwards.

Download from Australian server:

Download from Slingshot server:

9:56 p.m. 25/03/2012 - Slingshot LAX test?

Is it normal to see such wide fluctuations? I am new to all this so really need a little help.

Regards.

Can you supply a trace route when it is slow?

I'm not sure if you're asking for opinions on this issue, or simply posting it for comparative purposes.

If you read the 20 or so prior threads in this forum you'll see the vast majority discuss speed issues on Slingshot. If you're unhappy there are plenty of other ISP's in NZ.

I was really looking for some help / advice to see what if any actions I should take to improve this.
Yes I have read a number of other posts regarding speed and disconnect issues.
Yes I could change ISP's. This would of course mean paying a fee for breaking my contract. I would rather not do that if I can help it.

As I said I am new to modem / network diagnostics. There is a huge resource of clever people on this forum that far exceed my experience. I am hoping someone can help me make sure this is nothing to do with modem configuration, computer etc.

Thanks for the reply.

Take your results to your ISP, it looks like the Latency increases when hitting Tranzpeer, a wholesaler of International bandwidth

. I would further test to see if packet loss is occurring and if so, at which node.

**Just a noob myself so anyone feel free to correct me**

It is highly unlikely to be your modem or computer.

TBH it looks like contention in Slingshot's network or upstream providors.

We are having this issue in the following areas:

Listed here: http://www.geekzone.co.nz/forums.asp?forumid=81&topicid=99594&page_no=1#598983

Hi Guys

The traffic above goes via our Sydney Peering link bandwidth is congested during peak times due to Youtube users using 90% of the link.

Currently working on increasing bandwidth NO ETR at this stage.

Thanks

Thanks to everyone who has replied. It is very appreciated.
Joe:
Abbotsford Dunedin is the location.

Bevin:
I am not really sure when peak times are? I was experiencing this issue even with NZ servers on 22 - 23rd of this month. (And probably a lot previous to that given the nearly unusable browser.)
National speeds seemed to be resolved on the 24th of this month and continue to be OK.

Because I was proactively checking for problems, it was only on the 24 that I tried testing against overseas servers at varying times of the day and evening.

It would seem that 4.00.pm is the time International speeds (for me) seem to take a dive. It will drop from around 12.Mb/s to Brisbane to approximately 2Mb/s

7:53 p.m. 26/03/2012
All national down seems fine still.
International down is approximately 3.5 - 4.0 Mb/s.

Slingshot LAX:
Download Speed: 4124 kps (515.5 KB/sec transfer rate)
Upload Speed: 866 kps (108.3 KB/sec transfer rate)
Packet Loss: 0 %
Test Server: us-la

This is better than what I have been seeing over the last few days.
Slingshot chaps, how should I proceed from here? Is what I am seeing normal? Should I log a case with support?

Cheers.

Hi,

I would say that that is normal.

International at busy times (around 3pm to midnight) will drop to as low as the 3 - 4 mbps mark.

As long as national is ok and international ranges from there to line rate I would say there is no fault.

Thanks,
Joe.

I can understand the issues around day to night fluctuation, but over where we live (Upper Riccarton, christchurch), the speed almost never shoots above 0.25 mbps (download) and 0.20 mbps (upload) according to speedtest.net stats (which is quite believable, it does indeed look that way). We are on slingshot, and it does not matter which computer or OS we are talking (we have a windows box (vista), a windows 7, a mac osx lion, an ipad and an android device, and a linux (Archlinux I installed myself); it does not matter, same slow speed. We have to forget watching youtube videos let alone download movies or big files or ISOs. Even small (e.g. 20 mb file downloads will throw every other webpage loading to forever "looking up ..." messages).

I see now that Slingshot in this series of threads somewhere has posted that it is a known problem in christchurch, but I think what we are experiencing a little extreme. Any pointers, anyone? Any words to the wise? We have been with slingshot for the last four years since we came to New Zealand and never thought of changing ISPs.

Hi,

Are the Sync rates low too?

It could be many things at this stage.

If you PM me your account details Ill have a look at things from this end.

Cheers,
Joe.

Thanks to all those that chimed in. It is appreciated.
If slingshot considter what I see is normal then normal it is. Things (for whatever reason) have certainly improved for us over the last 5 - 6 days so I won't pursue the matter any further unless it deteriorates again.

Jason.

Statistically speaking such poor speeds are a typical indicator of poor internal phone wiring affecting your DSL speeds. Poor internal home wiring is the single biggest factor leading to poor DSL speeds (ignoring ISP's that don't provision enough bandwidth).

It would pay to start a new thread posting your ADSL sync stats from your modem, a brief rundown of your house phone wiring (ie number of jackpoints), whether you're using filters on all of them, and your location in relation to a Chorus cabinet. You can find this by looking at www.chorus.co.nz/sat
