Bras profile stuck (maybe)?

Hi all

Right then still finding my feet with this ADSL stuff (ex-cable guy) so bare with me.

A couple of weeks ago my ip profile dropped a bit down to 3000, which I am assuming was down to the little bit of rain we had. Now since then it has slowly been increasing and at the moment has made it’s way to 4500. The thing is when I run the BT speed test I keep getting results like this.

Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 4500 kbps
DSL connection rate: 448 kbps(UP-STREAM) 5120 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 2293 kbps

If you wish to discuss these results please contact your ISP.

Talking to a friend about this he said it is possible that my Bras profile may be stuck. Could this be the case?
If so what can I do about it?
Also I never turn my router off, should I be doing this daily/weekly not at all?
Any tips would be greatly appreciated.

Regards

Rob Wink

Your IP profile is correct for that sync speed. The throughput is a bit low but that could be down to exchange contention. Your IP profile will change to follow changes in your sync speed, albeit changes downwards can take effect within minutes whilst changes upwards take 3 days. In order to get your sync speed to change you have to get your router to resync either by reseting the DSL connection or by powering off/on. Whether resyncing will give you a higher speed depends on your downstream SNR ( see your router stats), if it is above about 9db then a resync will probably result in a higher sync speed,a lower SNR and eventually a higher IP profile.

What was your IP profile before the recent drop ?

If I remember rightly it was around the 4500 mark before the drop.
Is it a good idea to turn the router off when I am not using it or just leave it on?
As for the other stats if I am right one is about the 47db mark and the other is 14db (or there abouts). Not really sure what they mean as this adsl stuff is akin to the black arte to me at the moment Cheesy
The router does tend to hold a sync of 5000 = or - 200ish. But as I said I never really turn it off.

Hi there,

Have you checked your exchange VP status at http://usertools.plus.net/exchanges ?

Do the low speeds occur all the time, or only at certain times? What do you get here? http://www.mybroadbandspeed.co.uk

Hi

The exchange comes back as green on all counts. No problems.

I cant do the speed check at the mo as I am at work (sssshhh) Wink .

I wouldn't call them low speeds, just not as good as I think they could be. Am I wrong in thinking that the ip profile speed is the speed you can expect to be on?

Here are the results I have achived on the other speed tester you do. Not sure they will be of any help, but do seem to show the drop! Cry

Here:- http://www.kitz.co.uk/adsl/linestats.htm is a good explanation of line stats, much better than I could post here and a lot easier( for me anyway ). Turning the router off at night I feel is really down to personal preference. I used to turn my old Belkin off at night mainly because it ran very hot and I didnt like the idea of something that warm running unattended. My current router runs nicely cool and so I tend to leave it on except when I'm not at home for a few days. The only possible problem with turning on/off may be that if you turn it on during the day you tend to get a better SNR and sync at a higher speed, then when the SNR drops in the evening ( as it usually does ) the router will possibly resync at a lower speed. Leaving it on all the time eliminates this and it stays synced at the slightly lower but more stable speed.

Thks for the link....made my eyes bleed but I think I get it. :lol:

As far as I did understand it I am getting about what I should so thats fine. I think I might try the turning it off for a bit just to see if it will hold a slightly faster speed. So thanks for that info also.

So jus to go back to the original post should I be able to see download speed that relate to the 4500 profile or is about 3000 the most I can expect?

Rob,
It's really difficult to say what sort of download speeds you could expect , there are so many things that will affect it. I notice that most of your tests were during the evening and in reality that's when speeds are probably at their worst so 3000 is probably reasonable under those circumstances. If you cant get back to sleep sometime then try a speedtest at about 4 or 5 in the morning and you'll probably find it improves.
All in all I dont think you will get much improvement from your current figures under normal circumstances.

Thats fine I am happy with what I have. It was just the friend saying about the Bras profile might be stuck made me want to questioned it. God cable was sooooooo much easyier.

Okey dokey

My line speed/profile seems to be getting better but the download speed does not. Is this an indication of a stuck bras profile or not?

This was done at 20:30ish tonight.
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 4500 kbps
DSL connection rate: 448 kbps(UP-STREAM) 5120 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 3728 kbps

If you wish to discuss these results please contact your ISP.

These were either side of the bt test.

See above post for more tests.

The IP Profile is correct for your sync speed and your actual throughput is not a great deal lower. This is probably explained by exchange contention.

The non-BT speedtest results you've cited appear to be from the PlusNet checker on the portal, and this was never really designed for MaxDSL and cannot be considered accurate at higher speeds. PlusNet have developed a new speed test available here that will be integrated into the portal shortly.

If the results of this test are significantly slower than the "actual throughput" of the BT speedtester I suggest you check out this tutorial.
