Hi,
I have had BT Business infinity for 1 week. I noticed that the speed started off at 30+mb but has gradually been coming down and is now at 18mb. I tried the BT speed test and it said that the IP profile is 18352kbps, is that the max speed I can get?
The green box is about 25metres away and the exchange is 0.6miles (google maps). Surely I should be able to get better speeds?
At home the green box is about 25metres and the exchange is 1.5miles and I get over 32mb most of the time.
Is there something I can do?

It sounds low ... can you monitor it for a few days maybe with a power off reboot first thing in the mornings (they do not always seem to auto resync).
I have recently come across another line where they were able to get 30+ after a manual resync but then a auto resync would occur and it would drop to 20 or below. Gut feel on that was a that there is a noise problem that causes sync to drop and the noise is still there a few seconds later when the modem resyncs. Could be you have a local intermittent noise soucre/problem.

I tried that this morning and go tthis:
Test1 comprises of two tests
1. Best Effort Test: -provides background information.
Download Speed
16872 Kbps
0 Kbps 19359 Kbps Max Achievable Speed
> Download speedachieved during the test was - 16872 Kbps
For your connection, the acceptable range of speedsis 16000-19359 Kbps .
Additional Information:
IP Profile for your line is -19359 Kbps
2. Upstream Test: -provides background information.
Upload Speed
7868 Kbps
0 Kbps 10000 Kbps Max Achievable Speed
>Upload speed achieved during the test was - 7868 Kbps
Additional Information:
Upstream Rate IP profile on your line is - 10000 Kbps
Not looking good

Are you 100% certain that the FTTC cabinet is just 25 m away and the normal cabinet is adjacent?
If so, call the helpdesk and explain - they can try resetting the profile and margin and may have visibility of data that you cannot see. Stress te proximity of the cabinet and that something appears to be going wrong as you do get 30M + sync.
Also, check your internal wiring and any electrical/electronic equipment nearby. Do your tests with nothing else connected and using the socket behind the master faceplate.

There is no test port in a fibre installation.

Yes there is. Just remove the VDSL faceplate, as there is nothing special about it, and use the test socket either without a filter or with a standard one.
Just like a standard fiter, all the filter in the VDSL faceplate does is restrict the frequency range passing to and from the premises phone system to phone ranges. So the ADSLx/VDSLx frequencies don't make the phone unusable, and other noise arising inside the premises outside the phone frequencies doesn't get back onto the line out of the premises and possibly screw the broadband signal.

Your ISP in your profile is out of date. Perhaps your connection info too - if you are on FTTC?

Thanks - only been a year or more since I changed ISP's 
With regards to the "test port" on fibre, you live and (sometimes) learn, however the help desk won't ask you to try it, as it's part of the Openreach installation and shouldn't be interfered with.

Quick check, is the Openreach VDSL modem wall mounted ?
|
|
|

I phoned BT support, I was told to wait 14 days for the stabilisation period to end and they will investigate. Speed currently 17642 Kbps.
Zarjaz, there are hanging holes on the back of the VDSL model and I remember seeing a template in the box.

just tip it up on it's end...should stand up or lean it against something

Hi there,
If you're not comfortable drilling holes to mount the modem, then you can do what I've done and use double sided sticky pads and attach the modem to the wall that way.
Nothing to see here.. Move along, please

Just had a BT engineer, after some time between here and the box he decided to change the VDSL modem for one from the new batch as the old ones were prone to become faulty. So far my speed has peaked at 38/8 or 39.6/10 on his device. Hopefully that was the only problem.
Also he left me a template for wall mounting the VDSL white modem just in case overheating is the problem - the box is in an open space anyway.

No wish to sound smug. Now get yer drill out and wall mount the blighter, new model or not, it's better to be safe than sorry. The lazy scrote of an engineer should have done this for you.

It seems that the speeds have come down again:
Date 01/09/11 10:44:25
Speed Down 20280.30 Kbps ( 19.8 Mbps )
Speed Up 4561.23 Kbps ( 4.5 Mbps )
I tried the BT speed checker and the max achievable was 38/10. I don't think this is normal as I get 30+ all day at my other place.
I will have to check with BT again, I was told to call if the speed drops to below 30.
Edit: Just got a call from BT asking how the connection is (very efficient customer service!), I told them that it has not improved much. I have been told to monitor over 24hrs as the engineer did something at the exchange and I will get a call back before. I am pleased that they called me instead of the other way around.

I misread your first post, I thought you were asking if it was wall mountable.
Can it really overheat in less than 24 hours that much? It is a bit warm not hot, it is in open space. Might have to try.
Although I do have a new Draytek Vigor 2750VN waiting to be used as a complete replacement. I was waiting for the line to be sorted.

Nothing is wrong if the BT speedtest is giving 38/10 throughput. Don't rely on the TBB speedtest.

The BT speed test was giving 19/7 - the IP profile max achievable was 38/10.

Just tried another BT speed test and got this:
> Download speedachieved during the test was - 32998 Kbps
For your connection, the acceptable range of speedsis 16000-38717 Kbps .
Additional Information:
IP Profile for your line is -38717 Kbps

>Upload speed achieved during the test was - 7795 Kbps
Additional Information:
Upstream Rate IP profile on your line is - 10000 Kbps
Hopefully it will stay like that now.
TBB speed checker now:

I changed my internal wiring and the BT engineer changed the junction box connecting my 2 lines to one line going to 2 sockets from an ancient old nasty one to a new white one using some gel crimps I have never seen before. The speed did seem to stabilise but quite low about 16/4. Another engineer visited and disconnected the internal wiring and found the same errors on the external side. Apparently it was fixed but my IP profile has not been reset it is:
> Download speedachieved during the test was - 17514 Kbps
For your connection, the acceptable range of speedsis 16000-19359 Kbps .
Additional Information:
IP Profile for your line is -19359 Kbps
I am phoning BT now to as if they can reset it or something.
