Hey Guys, Was just curious to know what your Line speed is?

Mines currently
Upstream 782100
Downstream 5613900

When I was with my old ISP "iiNet" I had a sync rate of 7.6mbps, iiNet had a feature called Speed Control Manager, Comcen Don't seem to have somthing like this, or am I missing somthing?

Comcen Offer the following speed profiles,
1.5mbit
8mbit
12mbit
24mbit
24mbit Extreme

To have your profile changed please email support@comcen.com.au with your username and profile you want to change to

We certainly do, but it isn't something our customers can see from our members section (as our wholesaler does not allow access for anyone other than our staff).

If you wish a profile change, feel free to whim me your number / e-mail / call.

Thanks.

Thanks Anthony for the reply,

I have whim'ed you as Requested, When I last spoke to someone at Comcen they told me there was other speed profiles to select, but I wasn't exactly sure I wanted to be fitted on an ADSL1 profile?

Never the less I'm sure Anthony can fill in everyone here as well. I'll also play around with the settings and report back my sync etc.

System Up Time 16:11:57:30
ADSL Speed (DS/US) 19632/812 Kbps
Noise Margin 11.6 dB 13.9 dB
Line Attenuation 15.0 dB 5.8 dB
Output Power 0.0 dBm 12.8 dBm

Might see about upping my speed profile and see how much I can squeeze out of this connection. Albiet – I am more then happy with what I have got. Thats the best connection stats I have got in a very long time – 16 days and counting.

It's YOUR line speed, not You're.

What's speed profile? Why should we have to change it?

ttomomo writes...

Why should we have to change it?

from my understanding its to do with your line conditions etc and what they can handle.

for example if you have some slightly dodgy lines then going on a reduced speed/speed limited profile can help stabilise your connection.

from memory i do recall some people mentioning an insane profile aswell. that basically maxes your speed all it can at the risk of less stability.

Thats my stats for a 3.5Km line...

Mr.Gomo & ttomomo, you both have whim's ;).

Cool, Thank you anthony for the whim!

For those wondering what speed profiles Comcen have on offer they are,

1.5mbit
8mbit
12mbit
24mbit
24mbit Extreme

As I'm 4.3km from my exchange anthony has advised to me that I should try the 12mbit profile and see if it improves my line sync etc.. Should be interesting to see what I get! I will report back once my profile has been changed, and if it's lower then my usual 5.8mbps I might try the 24mbit extreme profile :)

I know Anthony told me before that my SNR would drop quite low and increase the likeliness of my connection dropping. But we'll see about that :) I think it really depends on the ADSL modem you have on your end..

Current Sync Normal 24mbit profile,
Upstream: 782100
Downstream: 5613900*]
Current Sync 12mbit Proflile
Upstream: 772000
Downstream: 5670000
Current Sync 24mbit Extreme Profile
Upstream 816200
Downstream 6653700

Wow I must say I'm happy with that kind of sync speed now! :) Lets just see how stable it is.. :) Damm Wish I had my speed profile changed earlier hahah

Anthony,

I have also sent you a whim requesting a profile change if possible

The only difference is the Noise Margin has dropped 2.3dB – stablility problems normally arise around the 6-8dB areas – so I am happy with that. Slight increase in speed – its more of a epenis thing than anything though.

How do I check this?

*loves asking questions that make her look stupid*

the info will be within your modem, login and look for something like "status"/connection.

Also just wanted to say Thanks publically to anthony and the comcen guys so far, speed profile changed within a matter of minutes from when I PM'd him from this thread... Cant wait to see the changes as I should sit around 20+ mb! Thanks again guys! :)

Yeah I'll say! Back when I was with iiNet we could change our speed profile etc, but it would take 12hrs to take effect :) this is freaking awesome! Good stuff Comcen

I am using a Billion, it's the one Spin sent me... Not sure what model number it is – will check when I go home and update it then :)

I have a Belkin N1 Vision also, but it's not hooked up.... but it looks pretty *lol*

Interesting thread.... definitely something I didn't know about.

In any event, not being able to access my router at the moment, the last time I checked (by chance yesterday) I had a line speed of 6610 with an attenuation of 42.5db (downstream).

Wonder what would be the best profile for my line.

Cisco 877W:

ATU-R (DS) ATU-C (US)
DSL Mode: ITU G.992.5 (ADSL2+) Annex A

Capacity Used: 100% 83%
Noise Margin: 11.0 dB 16.5 dB
Output Power: 16.5 dBm 12.5 dBm
Attenuation: 46.0 dB 26.0 dB

DS Channel1 DS Channel0 US Channel1 US Channel0
Speed (kbps): 0 5117 0 814

I currently have 'dsl operating-mode adsl2+' set. Would it be best to set this as 'auto' or leave as is? Also, what profile would you suggest I go on?

Cheers =)

DRK7, You could try the ADSL2+ Extreme profile but I would monitor the connection to see if you had regular dropouts, if you don't and are lucky like I seem to be, You'll end up with a higher sync rate and a stable connection

Hey all,

Feel free to e-mail support@ with any profile changes as I didn't realise i'd have such an overwhelming response :P. Bit hard to keep track of everyone via Whirlpool as I don't frequent too often.

Thanks.

Haha, Look what I've done Anthony! :) Should keep your support guys a little busy, When I was on the phone to comcen when I was first connected the guy didn't say anything about an extreme profile.. he just said he could change my profile to ADSL1 or ADSL2 profile.. might need some re educational to fix a few who are unaware of this option?

Okay, I logged into the modem and this is what it says -

Upstream 812kbps
Downstream 18490kbps
Noise Margin upstream 12.7db
Noise Margin downsteam 8.9db
Attenuation upstream 13.7db

*happy she worked out how to do it*

Yeah that's an awesome sync speed! :)

i get adsl1 speeds from 2mbit/s to 8mbit/s

and im on the 24mbit extreme profile

when i was on iinet i had no problem getting 17mbit/s

it's like i lost all that

*is embarrased now* :|

edit: does anyone thing it's because its ull and not what i was on with iinet different dslam = different speed travel to your house or something ?

it doesn't bother me that i lost alot of speed too much, im sure i can still max out my quota in a month

was just wondering that is all

would it have to do with maybe alot of people using offpeak also on the network that it cant handle the speeds?

and the network is conjested <--how ever you spell the word

creating email addresses with iinet took 2-3hours but with comcen you can do it via member's page and get it done in few mins

that's what i like to see :)

Freestyler, If you want more downstream then yes, and looking at your line spec, it wouldn't effect stablitlity at all with the extreme profile enabled.

FYI My connection has stayed online for the past 24hrs ;) Stable it is so far so good!

Andy, Make a new thread for that if you want to talk about that :)

My modem says 15806Kbps down, 812Kbps up.
That said, I am struggling to get more than 350KB/second on speed tests.
My friend who is 1km from me, also on Comcen, is located around 1km from the exchange. He's also got crap speeds.
So much for ADSL2+..I should have stuck with Indernode 8000 plan..at least then I could still be getting 750-800KB.

I can pull over 1mb/s on torrents – and also from PIPE connected sources.

Hey,

Just wondering If The Upload is capped at 812kbps?

I know other ISPs offer 2560kbps upload but I think they charge more. Any ideas? we're sharing the connection with 4 people so upload is important. Don't suppose there's anyway of getting Spin to offer me a better upload, I'd be willing to pay a bit more ;)

I'm getting spin in a weeks time, I'll post my line speed then. my modem is billion 7300g so it should FLY I'm 1018meters from the exchange, checked on http://www.adsl2exchanges.com.au/

Thanks guys!

How do i find out what profile I'm on? anot not knowing to much do the stats below indicate good or bad?

Up Stream 812 (Kbps.)
Down Stream 19145 (Kbps.)
Noise Margin 15 dB (upstream) 8 dB (downstream)
Attenuation 13 dB (upstream) 15 dB (downstream)

Edit: I'm 381m from my exchange i might add :)

pejamas writes...

Noise Margin 15 dB (upstream) 8 dB (downstream)

You could probably go on the ADSL2+ Extreme Profile – however it may cause you some instability issues with your downstream noise margin. 8dB is in the grey area of instability. Just watch that – especially if are currently experiencing some sync and connection now.

Here something to go on anyway.

Noise Margin (AKA Signal to Noise Margin or Signal to Noise Ratio)
Relative strength of the DSL signal to Noise ratio. 6dB is the lowest dB manufactures specify for modem to be able to synch. In some instances interleaving can help raise the noise margin to an acceptable level. The higher the number the better for this measurement.
6dB or below is bad and will experience no synch or intermittent synch problems
7dB-10dB is fair but does not leave much room for variances in conditions
11dB-20dB is good with no synch problems
20dB-28dB is excellent
29dB or above is outstanding

Line Attenuation
Measure of how much the signal has degraded between the DSLAM and the modem. Maximum signal loss recommendation is usually about 60dB. The lower the dB the better for this measurement.
20dB and below is outstanding
20dB-30dB is excellent
30dB-40dB is very good
40dB-50dB is good
50dB-60dB is poor and may experience connectivity issues
60dB or above is bad and will experience connectivity issues

Ultimately some modem's will get better sync then others – make sure you update your profile with your modem and new ISP

Yes – that is what OPTUS have limited their DSLAMS to sync at.

I know other ISPs offer 2560kbps upload but I think they charge more.

Yes they do – however your exchange has to be installed with their own DSLAMS. They are few and far between.

Looks pretty respectable to me. Whats the best I can hope for?

I have just changed from Virginbroadband with a typical 18KB/s download speed so, this is heaven!
But, I would welcome comments as to how good such a speed is for a new entrant into this elevated universe.

I do have a 17 meter phone extension cable between the Telstra connection and my modem. I guess that might cause some attenuation?

If I can get more speed, I might put in a wifi link.

Bobthequill

Sorry, Double post. Thought it was hung. Same speed problem perhaps?
Bobthequill

Bobthequill writes...

Is this normal?

Bob it is because the speed tests sites are inaccurate. You have no idea of the load on the server. You don't know if things are downloading in the background on your PC i.e. Microsoft auto downloads. Your example proves this – if in the space of 10 minutes you can do two tests a get a wildly inaccurate figures like yours. Well that shows you the evidence.

I do not use them – I use well known links – Pipe Connected Sources – Trusted Torrent Sites to test my total speed. But rest assured – if simply rebooting your PC fixes a speed related issue – it can confidently be identified that the PC was causing the slow down – not your connection.

Here's my example of how it is not reflective of your true speed – /forum-replies.cfm?t=993178&p=5#r96 – in the end speed tests sites are just sites like everything else – they have bandwidth problems – they have load issues. They are not the yard stick of which to measure your connection.

Hi,

I am having TERRIBLE speed at the moment on my ADSL 2 connection.

Did the speed test at the Comcen website and got a download speed of 160.38KB/sec.

Just did the Oz Speed test and got:

My line sync speed is 11500kbps approx.

Not sure why it is so slow.

But right now I am barely getting ADSL speed and this is meant to be ADSL 2 :(

For a speed test, try this link:
http://www.crc.id.au/galaxy.mpg

That server is usually not under much load and should be very quick. I can stream the whole 100Mb of this MPG file....

LOL writes...

LOL – refer to the post directly above yours in regards to speed test sites and the like. Just remember just because you sync at 11Mbps – doesn't mean that every site you download from is going to deliver that speed. Most download sites load limit and throttle because they themselves have bandwidth throughput problems.

However – a speed test site is NOT the yard stick to measure your connection.

Wheres the other links that are slow for you? If you are getting slow speeds in P2P – consider going up to the Peer to Peer Section and asking some questions. If it is general links – post them for comparison – so others can test them as well.

I find I am mostly up at 0.7 or slightly more with OZ broadband speed test, but if I am downloading from a specific site with DAP, I get slightly better.

One thing I did realise, I have just moved to Comcen from an incredibly slow Virgin Broadband @ home wireless service. Some of the desk top links to my favourite sites, I didn't bother to update, assuming they would work Ok. Those that I established by dragging from my favourites list while with Virgin, I found were still incredibly slow. Then the penny dropped, they are still linking through my old ISP, even though I no longer have the wireless modem!

So I quickly established a new favourites list and lo and behold, the speeds are all fantastic.

Hi Guys,

Just get connected with Spin today, however seems like I got some issues with the connection speed, it's only max at 200+KBs, I think it is far more less than the standard speed of ADSL2+.

From your figures I am predicting you are much further then 500m. Your Line Attenuation Figures are absolutely shocking. You are only syncing at 210kb/s download and 31kb/s upload – thats why you are only maxing your speed at 200kb/s.

If you are indeed so close to the exchange I am hedging the bet that your filters may not be ADSL2+ compliant – or something is interfering with the signal at your end. Make sure all your phones are filtered – and that you have the filters installec correctly. Do an isolation test (search whirlpool if you don't know how to do that) – post back with your results.

Thank you very much for the great advice AuS.

Yes did the isolation test so the problem is caused by the filter?

Gonna to get myself a new ADSL2+ compliant filter if it's the filter fault, as this filter came with the Billion 7402L modem so I thought it might work fine same as ADSL. Hope this problem will get solved with the new ADSL2+ filter. below are the results.

telstra are reluctant to give adsl to anyone with over 56db attenuation so that should tell you how bad it is to have that high a figure.

Hope this problem will get solved with the new ADSL2+ filter.

your results clearly show a massive difference, showing how much damage to your connection your current filter is doing.

Thats what it should look like. I would recommend that you check have the filter installed correctly. Make sure the filter is installed the correct way – not reveresed – especially if it is single port inline one.

To be honest from the testing done I think you might be filtering the modem. Remember the modem does NOT get filtered. Are you able to take a picture of the filter setup – or describe what you have got plugged in where?

Incorrect filter setups account for a staggering amount of ADSL problems. Especially to new users and ADSL2+ – you can get away with it on ADSL1 – withouth the speed sync problems showing themselves.

All these nice people, with great information, and all the sharing and caring is making me all warm and fuzzy inside.

Nice to see :)

Hey Aus i have a telephone jack upstairs with a telephone connected i run a filter on it one i have had for awhile. My computer is connected downstairs on a jack through my modem and connected and filtered etc. Now i know all those line speedtest sites vary so much that they are not really accurate. It is frustrating to always seem to have different speeds sometimes ie last night wp was very slow and not under heavy load.
Do you think an old filter upstairs might slow things down.Maybe run an isolation test i suppose. Modem stats are always around 11.3 to 11.6 up and 810 down

Umm – Your modem does NOT get filtered. If you don't have a phone down there – it should plug straight into the wall i.e. phone cable going from the modem to the wall socket. NOTHING IN BETWEEN. Any phone you have in your house should be filtered.

Uhh sorry my modem is connect direct through a piggyback with adsl direct on to the modem and line through i think a filter to line connection on my modem with a telephone connected to my modem only used as pstn at the moment when i turn modem and computer off still can make and receive calls.Modem is Billion 7404vgp-m

Things like slow websites are not to do with top download speed – but other issues like DNS, MTU and Client PC network configuration.

MTU explanation and step by step testing here:- http://help.expedient.com/broadband/mtu_ping_test.shtml

Check what DNS servers you are using (make sure they are not your older ISP's ones)

Running P2P – at full upload limit – or in the background – will increase your webpage loading times due to choking your ['ack's] going out. Short tip is – make sure if you have any P2P running – you set the upload limit to no more then 80% of your upload limit. I.e. Upload limit 100kb/s – should set it to 80kb/s.

AuS

Edit – I am in a bit of a hurry – but will check back later to see if you need help with all that.

AuS writes...

Yes – that is what OPTUS have limited their DSLAMS to sync at.

Yes they do – however your exchange has to be installed with their own DSLAMS. They are few and far between.

AuS

Ahh, thanks AuS,

Kinda sucks but at least its not a Spin Limitation, makes me feel better about them. Still a pretty good upload, but I was considering cable which has 3mbps upload :O Cable has lolworthy download limits though...

Be careful – many cable plans count upload and downloaded data into your allowed data. i.e. it gets counted both ways and if you go over you get shaped. To my knowlegde – they all do this. You get a great upload speed – but you just can't use it.

AuS

Still not having any satisfaction with my speed.

For the last few days Comcen Tech staff has been resetting my conncection from their end.

Straight after the reset I have been able to download from the Comcen Speed test site at approx 800 Kb/sec – 1000 Kb/sec.

Then after a bit of time my speed is reduced down to 150 Kb/sec -300 Kb/sec

I am extremelby dissapointed with this as I am getting decent sync speed and getting slower speeds than standard ADSL.

My sync details are below:

Operational Mode ADSL2+
Upstream 473 kbps
Downstream 11468 kbps
Noise Margin (Upstream) 12.0 db
Noise Margin (Downstream) 11.0 db
Attenuation (Upstream) 15.2 db
Attenuation (Downstream) 24.0 db

Can anyone suggest why I am not getting any consistency; Comcen says all is ok and is giving no answers.

But clearly something is wrong.

Update your modem firmware to the latest, reboot, reset to factory defaults, and try again.

Sounds like something is screwing your modem up.

I actually had the latest firmware for the Billion 7300G.

I set it back to default firmware and the speeds appear a little quicker.
But still very unstable even now.
I am getting between 270 KB/sec to approx 500 KB/sec by trying the comcen speed test randomly after each other.

And now I am only getting around 100 KB/sec after 12 AM. Is this because off peak has now hit?

Router settings are:

DSP FirmwareVersion DMT FwVer: 3.7.6.98_A_TC, HwVer:T14F7_1.0

15.4Mbit does me fine :)

Nice one Mega.. I assume that you have relocated your services now, and no longer have that 300kb/sec cap occurring?

MuRDeRiSH writes...

IMHO no.

SNR Margin 4

a downstream SNR of 4 is bad. go back to page 3 of this thread and read the post AuS did about it.

[edit] the SNR Margin seems to change

i would be checking your cables, connections etc as a first step. also an isolation test to make sure nothing else plugged in is causing this.

sometimes the snr drops lower than that also ...

I was getting ~16500kbps about 6 months ago and was pretty happy with that but was pleasantly surprised when I checked again today.

Speeds have been very good for a while now comcen keep up the good work.

Keep an eye on that downstream Margin – that is insanely low. If you start to experience sync or drop out issues – start working on getting that margin up about i.e. going to a more stable profile.

Here for more info – /forum-replies.cfm?t=1004156&p=3#r55

For comparison my sits about 8db – it used to be 10db before I went to the Extreme Speed Profile. Just something for you to keep in mind.

I called Comcen and they changed me to thw 12mbit profile as I wasn't getting that high of a speed anyways and that brought my SNR up to 12 ... he told me to check me a different modem as it could be my modem not handling that speed ...

AuS writes...

Yes is it for sure, its always been around 5 or 6 (I think) and sometimes down to 4. I've had drop out problems in the past but not for about 3 months now. When I was getting them it was only maybe 2 or 3 times a day which I could live with. I still get the odd dropout but Its been pretty rock solid for a little while now :)

I'm not sure why my sync speed has jumped up 2 Mb/s second though from when I last checked which was a loooong time ago.

What kind of speeds should I expect. According to adsl2+ exchanges I'm 1.7k from the exchange, but probably 2.5k in copper. I see that my SNR is quite low, should I be changing my profile?

MuRDeRiSH writes...

ye thats possible aswell. unfortunately not all modems are made equally.

let us know how you go with a different(meaning different brand aswell if possible) modem.

~CJ writes...

in theory with that attenuation it should be possible to get over 12mb/s best case.

I see that my SNR is quite low, should I be changing my profile?

as AuS explains back on page 3 such a low SNR is not good for a stable and reliable connection. it may be worth asking to be put on the 12mb/s profile and see if that helps your connection or not.
also trying a different(brand) modem is worthwhile if you can to see if there is any difference.
