Banded Broadband

Ch4d — Fri, 30 Jun 2023 11:35:11 GMT

Hi,

Hoping someone can help as my connection is being limited and seems stuck on a banded profile of 60/20.

Line is stable for over a year now.

Can someone please look into remove the cap so as to achieve full potential of the line?

Thanks 🙂

DLM usually removed banded line in their own time! Don't think BT will able to remove it off unless there is a fault on the line for the engineer to attend to repair fault then resetted DLM. If no fault, then nothing BT can do about it. You need to wait until DLM will removed banded in due course.

your stats, probably tplink, don't show internet connection time or system up time

Its a Draytek Vigor 130, running into a Vigor 2925ac.

I've seen 3500 hours system up time before, but we had a power cut over a week ago.

The connection stats haven't budged for at least two years now.

The available lines speeds have increased in the last few months as our estate has been upgraded with FTTP and quite a lot of Openreach vans have been flying about upgrading people.

Just wanted to see if there is an easy way to make use of the spare capacity.

Thx

You seem to have a fairly high CRC error count.

I would be extremely surprised if you noticed the difference between 60M and 67M in any case.

system uptime just shows how long system has had a power connection and not same as internet connection time which is the important time

I assume using the terminal window, you've already used the "vdsl snr" command? If not then using a negative command will try to force the SNR lower. As the cabinet ALWAYS has the last say, you can try "vdsl snr -50", noting though that if you do increase the download speed the upload speed will usually decrease.

*Just don't play with that command too much or DLM may kick in as it reboots the connection everytime!

As DLM has banded the line, nothing other than a DLM reset by Openreach will have any effect.

Played with that setting years ago and did get higher rates.

At the moment no snr changes are in play.

Well just spent over an hour on the phone with BT repairs, then another networking department.

My local cabinet has recently been updated with vectoring, and the attainable download speed has increased to 78mbs.

Sync is still restricted to 60mbs as before.

BT wont do anything as there is no fault on the line and its stable.

They will however get an engineer involved for £185.00 with no guarantees.

So unless I have a faulty line they will not do a DLM reset or remove the banding. 😞

Just pondering if its a marketing move to force us onto FTTP as its available in my area?.

obviously still in banded profile but as I posted before your stats don't show actual internet connection time. if you are having stability problems with connection dropping then banding will not release

However as this has been going on for months I have asked mods to see if they can help with banding. if line unstable then banding will be back again in days/weeks

Re: Banded Broadband

Hi,

The line is completely stable, been running for 450 hours since last had power outage.

Prior to that it was about 3800 hours.

Re: Banded Broadband

imjolly — Wed, 13 Dec 2023 13:32:52 GMT

as I said before that shows system uptime which is time your router has been powered up not the length of time of your internet connection which is different

Re: Banded Broadband

Ch4d — Wed, 13 Dec 2023 13:36:08 GMT

I have a Draytek Vigor 130 modem which is bridged through to a Draytek 2925ac router. The Vigor 130 never gets powered down.

Re: Banded Broadband

licquorice — Wed, 13 Dec 2023 13:38:18 GMT

@Ch4d you appear to be missing the point.

System powered time is irrelevant, it is broadband uptime that is the pertinent parameter.

Re: Banded Broadband

Ch4d — Wed, 13 Dec 2023 13:44:03 GMT

Quite possibly I'm not getting the point, but as I understand it the Vigor 130 maintains the internet connection as long as it remains powered. Other than that I'm not sure.

The Vigor 130 status shows system up time, this resets to zero if the modem is powered off or the internet socket is unplugged.

Re: Banded Broadband

licquorice — Wed, 13 Dec 2023 13:56:35 GMT

The Vigor won't maintain the internet connection if the copper wire outside your house becomes disconnected. That is what we are trying to ascertain, not how long the modem is being powered. If your broadband line is unstable and is intermittently disconnecting it will cause DLM to act.

Re: Banded Broadband

Ch4d — Wed, 13 Dec 2023 14:00:08 GMT

Ok, seem that you mean.
The connection isn't dropping or retraining.
I suppose if line quality was an issue there would be interleaving delays, but its always fast path for upload and download.

@Ch4d

Just pondering if its a marketing move to force us onto FTTP as its available in my area?.

Why not switch to FTTP if it's available? It removes all of these sync rate and banded profile issues, and you should be able to get a package that's a similar price to what you're currently paying.

Re: Banded Broadband

Ch4d — Thu, 14 Dec 2023 09:19:56 GMT

I would at the drop of a hat.
Problem is its a company owned line and apparently BT only allow 3 year contracts for FTTP, currently its on a rolling monthly.
So really I'm just after optimising what's possible.
Also its only a matter of time before the copper switch-off comes into to play and BT may offer an upgrade package.
