Wheres the bottleneck in my internet speed?

[peteed1985]

Ok I have an Optus branded Netgear DG834GUv5 modem/router and a GA-Z68X-UD4-B3 motherboard with onboard LAN.

I have exetel ADSL2+ and before I had Optus internet.

The MDF on my block of units as well as all the phone lines is new and works 100%.

The sync speed between the exchange and me is 7 to 12 Mbps according to exetel over the phone and also my modem can see the 12 Mbps line too.

However exetel speed tests and Ozspeedtest both show erratic and widely different speeds ranging from 900 kbps to 3.3 Mbps and at rare times 6.6 Mbps for a very small amount of time.

So by the looks somewhere between my modem and my PC I am getting a major major major major major loss of 90% of my speed.

Exetel says my modem is setup right and they can't work out where the speed is going and noone is leeching my wifi, I checked to be sure.

Help?

Have you tried speedtest.net? I find it's pretty accurate and consistent. Also try downloading a linux image from the AARNet mirror if you have the quota to spare: http://mirror.aarnet.edu.au/pub/ubuntu/releases/12.04/

See what your download speed is. Remember that megabits (mbits or mbps for speed) is at a ratio of 8:1 for megabytes (1mb = 8mbit).

Sounds like your connecting wirelessly and have downloads going as well whilst your testing.

as above post mentions try speedtest.net
make sure you have no torrent programs open at all. and see how you go from there.

if your connecting wirelessly.. you won't have a stable speed and it will be all over the place.. though should still be hitting the 11 - 12 mb/s

Nope and nope. I have never used anything other than LAN for net and have a fresh windows (all latest drivers) without torrent programs and had no downloads going.

hmmmmm. how far away from your router is your computer ?
and is the ethernet cord passing by anything that could interrupt the packets ?
eg microwave, hellogen lights, home nuclear lab ?

also. try see if you have a spare laptop and plug that in.... see if same thing is happening.

thats about all i can think of.
good luck

1m or 1.5m ethernet cable.

Nothing like you describe near it that could interrupt the packets.

No laptop.

Your sync and download speeds look quite normal to me.
I sync at about the same speed 12mbps and even downloading from a local mirror here in S.A the max i get is about 1.1mbps.

I am sure this logic may be flawed, but i look at it from the old 56k modem days, if i connected at 56k my maximum download speed will be around 5-6kbps.
These days i divide my sync speed by 10 and that seems to be a fairly reliable estimate for my max constant download speeds.

12mbps should download at 1.1MB/s not 1.1 Mbps lol

I may be way off course here, but..... this sounds like congestion on the network you are accessing.

Ozspeedtest is not reliable at the best of time, as the other posters have suggested.

This test works well for me, even though I think the ping is slightly out in my case. I can hit 6-8 mbps regularly on my 3g wireless.

I suggest you run a few test to gain some averages. ie at 7am, 7pm, 1am
If the performance dips at 7pm , like every bugger in your neighbourhood on the internet at the same time. Then you'll have your answer.

So just turn off your WIFI, update your modems firmware to the latest and put your user/pass back in and resync then do a speedtest. Also you need to try and download something from a server capable of maxing your bandwidth to get real-world results, like a torrent with lots of seeders, Microsoft, or by using a download accelerator of some sort.

Apparently Exetel NSW has 2 x 500mbps+ bandwidth for the whole state via thier optus network which is double any other state however NSW is the only state with 23.5/7 congestion.

Almost the entire day Exetel has 1400 to 3000mbps going through thier roughly 1000mbps connection and only around midnight area does it go down to 800 to 900mbps for a very short while.

How do you get this statistic? By the sounds of it, if it is like you say then Exetel is oversubscribed in your area.

Here's a link to what exetel says about slow variable speeds.
