What is the maximum Sky Speed?

I'm a little confused, I've read that it's 20Meg then again I've read that it's also 22 or 24 max

I originally had a stable sync at 22mb but for some reason Sky in error started retraining my line. After the 10 days I could only sync at 18mba so I emailed Sky to change this but said they could only change it to 20 because that's all Sky offers. I explained by return mail that I previously subvert at 22mb and got this reply, below;

The reason that we can only supply 20Mbps is due to that is what is offered by sky, which is explained in all terms and conditions. I can advised that your line can support more than this however it will be capped at 20Mbps as this is the terms and conditions of sky.

If you would like to check this out further I would advise you to have a look at www.sky.com/broadband.

So, they are saying that nobody can get above 20 because they don't offer/support it

Have you requested Gaming mode on your connection?

But where does it say anything about 20 Meg?

"The reason that we can only supply 20Mbps is due to that is what is offered by sky"

Just spoke to them on the phone and they confirmed Sky is only upto 20Meg and no higher...

Yup, i'm on the 'Gaming Profile'...

You omitted the phrase "which is explained in all terms and conditions" from your quote of an email response.

And I'm asking where is it written in the T&Cs? What have they to back up an after-the-event assertion in an email?

AH! Sorry for the misunderstanding... I just copied and pasted the email sent from Sky and didn't realise the link was broken...

In all honesty I haven't looked at the T&Cs but what I don't understand is that I previously subvert at 22MB and now they are saying this.

The ascertain do in fact state 20MB but others have said it's upto 22MBand in some cases 24MB.

None of it makes sense to me, if they don't support it then how on earth did I previously sync above there supported rate?

I will take a look at the website now but I know for sure I got a higher and stable sync as my previous posts in forums here show my line stats as I was discussing other issues...

In fact, looking here on ThinkBroadband it shows Sky Broadband as 20+ Meg :/

Officially the max is 20mb. Depending on what equipment you are connected to in the exchange & how good your line is you can potentially get 22mb or so.

If you are connected to SVBN equipment you can only be manually set to 20mb not higher because this is all their profiling system goes up to. DLM however could set you above this if the line is good enough.

The easynet dslam's have more manual configuration options for the advisors and therefore you could see higher than 20 if connected to these, dependant on line conditions of course.

Well, I couldn't find any reference to 20MB on that page given but found this;

http://www.sky.com/products/broadband-talk/broadband...

They must support faster and it depends on who you speak to because I previously got 22...

20Meg will do, bring on Sky Fibre ...... Eventually, we may get it :/

You can get higher than 20 but as I said it totally depends on the conditions set out above.

I'm using the Billion 7800n (snr tweaked) on Easynet...

I suppose the lady who put me on 22MB liked the sound of my voice

Ah if you're on a globespan easynet dslam that would be no issue, it could just sync to the 7db target SNR or lower if tweaking with the broadcom chipset.

Problems arise when you are on the SVBN profiling system, you can only get above 20 by DLM, have you been moved over perhaps?

Just checked, still on Easynet. I assume it depends on who you speak to and what they are prepared to do and know... My line is a very stable line, so it's the 2 guys from Sky today who either wasn't prepared to set it higher or didn't know how...

Yep e-mail is a pointless task in my experience.

Phoning up and requesting to be put straight through at a quiet time to CST usually does the trick (if the tier1 agent cannot deal with it) - they can then just resync the line to the 7db target or you could ask them to uncap to 24000 to allow room for snr tweak.

Well, there you are then:

In reference to www.sky.com/products/broadband-talk/broadband/facts:

Up to 20Mb broadband availability depends on your location. Speeds vary with location and line quality.

They only advertise and therefore commit to up to 20 Meg.

It doesn't matter if it's technically possible to go faster, Sky will only guarantee up to 20 Meg and you can't complain if you are taken down to 20 Meg.

I think if you get DLM to run again this can set speeds over 20 mbps

Other than DLM I don't think there's a way

& I'm not sure 100% if DLM STILL allows this

I've previously seen a post by a member of sky support staff, who said that on SVBN the automatic DLM could set sync speeds over 20mbps, but if configured manually, they could only select from a very limited pre-configured sets of line profiles, none-of which exceeded the advertised 20mbps. If you do connect over 20mbps then you'd almost certainly also have the minimum delay, so don't call up asking to be put on the gaming profile, as you'd just lose speed.

Yep Sky can't set profiles above 20mbps. DLM can

Sky have a few profiles that they can manually set. 4 meg, 10 meg, 16 meg, 18/19 meg. I think that's it.

A while ago they could set whatever speed they liked e.g. they could enter in a random number. Now they can't

So the best solution is to ask for DLM to run and hope it trains in higher.

Also any profile below the highest one has a restircted upload to 765 kbps

How smug do you feel? Most peeps get at the most 6mb and you are whining about not getting 22 mb.

I suppose your'e not interested in getting FTTC if you are getting those speeds through ADSL.

Your very lucky mate, make the most of it...

Thought I would email them and give it another try and just received a response saying they have released any sync capps and place me on gaming profile, now im synced at ADSL

672 / 20476 kbps

Why is it that when they place you on the Gaming profile, you lose speed? I don't understand this and I noticed it a while back when I had a few issues...

I thought it was a case of having interleaving on or off and if interleaving is on then you lose a little speed, not the other way around

In reply to a post by ukhardy07:

That explains why I only get 800 Kbps upstream !

If you let DLM run it can set a profile upto 1200 kbps upload.

If you ring up sky and have them do the sync speed manually the uploads restricted.

You can request DLM to be re-run, but ensure you ask for them to select the "stabilize" option also. Otherwise it wont force the line to retrain. They often don't select stabilize if you just request DLM to run.

Thanks for that but I can't see how asking to have the DLM re-run will lead to a faster upstream speed as I have quite a long line ?

My downstream attenuation is 53 dB and my upstream attenuation is 33 dB

Is the SNR on your upstream already 7db

If its higher DLM can extract more upstream

Whether it will or not - it's all a guess.

No it varies between 10 and 11 dB

Yeah basically if you ring sky they have fixed profiles. They generally cannot give you an upload above around 765 kbps.

If you let DLM run it can set the upload much higher. DLM can set an upload upto 1200 kbps - which in practice syncs at 1100 kbps for some reason.

DLM can set a high upload speed regardless of the download speed.

As your SNR is higher than 7db DLM will probably increase the upload speed.

Basically sky customer services even CST are restricted by the profiles. DLM can set different profiles which are higher.

Customer services can only give a 1.1 mbps upload on around 18 mbps download profile.

DLM can give a 1.1 mbps upload on a 2 mbps download profile

See the difference?

It's the same with people syncing over 20 mbps.

Sky customer services cannot give speeds above 20 mbps. DLM can give speeds above 20 mbps.

Thanks I'll give it a try

True but they can still manually configure lines which are connected to the Globespan easynet equipment.

No idea why they thought capping upload on all profiles at 800k except 18/20 was a good idea tho!

So it's only the FULL LLU that has fixed profiles?

ya, if you're still on partial manual config is available. For example down/up, max delays, INP, fastpath/interleave - though they're not supposed to touch it but some have got lucky with fastpath by advisors not knowing the policy I guess
