Another thing that's interested me is that my attainable download is 42564 but my line rate is exactly 40000, and my attainable upload is 6983-7006 (as it keeps changing) and line rate of 6972.

Is it normal for the download line rate to be locked so specifically? Looks (to a noob) like it's been locked at Infinity 1 speed?

1. What FTTC Range A and Range B speeds does http://dslchecker.bt.com/ state for your line?
2. Now you have unlocked your modem, consider signing up to http://www.mydslwebstats.co.uk/
3. You may want to try seeing what speeds you get if you plug your modem into the BT test socket (i.e. remove the Mk3 filter)
4. If your line speed doesn't eventually increase further (i.e. if G.INP is activatedif you are on a Huawei cabinet, consider downgrading to downgrading to the BT Infinity 1 service..(which operates at 40/10MB)

The way to tell if you're on Infinity 1 or Infinity 2 is to check your upstream IP Profile. It will be 10 for Infinity 1 and 20 for Infinity 2.

You can get your IP Profile by running www.speedtest.btwholesale.com and going on to do the Further Diagnostics, or by using https://windows.mouselike.org/be/index.asp?DoAction=BrasChecker

Thanks all to have replied!

. . . my attainable download is 42564 but my line rate is exactly 40000, and my attainable upload is 6983-7006 (as it keeps changing) and line rate of 6972.

The "BT Infinity 1" service is the retail of the Openreach 40Mbps DS / 10Mbps US synchronisation product.
The "BT Infinity 2" service is the retail of the Openreach 80Mbps DS / 20Mbps US synchronisation product.

Your VDSL2 circuit is capable of 42564Mbps DS and somewhere about 7Mbps US. That is maximum attainable speed, determined as the DSLAM - modem performed their parameter interchange at the moment of their synchronisation.

Your ISP/CP (BT) have capped the circuit to 40/10 Mbps (i.e. "Infinity 1" service) and should be charging you at the current rate for that service.

I had a conversation with BT a few years ago, something like 3 years ago (as I remember calling them handsfree when I was driving because I knew I'd be on hold for an age, and was), and they said at the time that I could switch to Infinity 1 as I may never see more than Infinity 1's speed, and I suspected at the time that my line had been locked to Infinity 1 speeds and had a conversation about that with them as well but they said it wasn't, but I am and always have been charged for Infinity 2 speeds.

No, his upstream could be capped at 10

my attainable upload is 6983-7006 (as it keeps changing) and line rate of 6972.

That looks to be the case, sorry I have done the BTW speed test and further diagnostic page, will attach the photos to this post or to the next one.

1. Please see I've attached the BT DSL Checker
2. I've already signed up in anticipation of unlocking my modem, but not had a chance to set this up as of yet (also going to donate so that I can get more than 5 days of recording of stats) I won't likely get a chance to set this up until Saturday as I'm round the girlfriends the next couple of evenings
3. I had considered this but didn't know if this would produce any better speeds as I got the Mk3 faceplate, but happy to try! Theres nothing else on the line, as I had the line put in just to be dedicated for Internet usage.
4. From the unlocked modem pages is it possible to tell? (I think I saw somewhere you can tell from the telnet sessions and with mydslwebstats) But yes I'm on a Huawei cabinet at the top of my hill

Dray, it does appear that I'm stuck on the Infinity 1 option, which if I've understood this correctly could only be corrected with a reset of the DLM?

Will have to split the attachments into a few posts.

Thank you very much for the help so far, don't feel I've said it enough, really impressed by the support this forum has offered even prior to signing up! Attached to this post is the BTW tests from before I replaced the face plate, and the BT DSL Checker results (that I just ran).

Happy to provide or do anything that you suggest that may improve my connection, I'm determined to get the utmost out of my line by tweaking! So please feel free to suggest or request I do things for further info, and again, many thanks for the eyes and opinions that have been provided!

They have indeed got you on the Infinity 1 package even though you're paying for Infinity 2. I think they owe you a refund as simply putting you on Infinity 2 won't give you a speed increase.

So the difference between Infinity 1 & 2 is just the capping of the line not different frequencies? I'd always thought that Infinity 2 used more frequencies

That was a rumour that did the rounds last year, a couple of years since Openreach moved from 8c to 17a. But no, the 17a profile applies to all connections and the only difference between Infinity 1 and 2 is the speed cap.

[Bald_Eagle1]

It looks more like your connection simply can't currently handle more speed rather than it being intentionally capped by BT.

Sight of your connections stats would be really helpful for us to try to assist (if possible).

Your current speeds do seem incredibly low for only 400 -500 m from the cabinet.

The DS IP Profile from the BT Seed test further diagnostics suggests a line length of somewhere around 900m or slightly more.

There could be quite a fault (internal or external), you could have quite a 'noisy' connection or your actual line could exceed 500m bit quite a lot (or it could be aluminium).

Your speed estimates do suggest that BT 'know' that your speeds are unlikely to be much higher than you currently achieve.
These might/might not be based upon actual data from your line or others in your immediate vicinity.

Yeah no probs I'll grab a screen shot of the stats and setup mydslstats stuff so it can start recording.

You may be right in terms of the line length, I was just guessing and used a point to point mapping tool, and probably being optimistic

I'll try a quiet line test and connecting directly to the master socket as has been previously suggested, as nothing else is connected to the line can one leave the modem plugged into that socket constantly or is it not advised?

When the BTOR engineer was on site doing the install with his gadget thingy ma jig that tests the line he suggested a speed of around 60ish was indicated, which is why I'd guess I can and did order Infinity 2 at the time.

Much like yourself, I too am more interested in upload bandwidth.

If I get a mo, I'll remote in home and log into the modem and screen shot the statistics for you

[LudaLuke]

Also I was reading through another members post about home plugs and I have 3 around the house, none anywhere near the modem, could this also be affecting it? The other line in the house has DECT phones on it which are unfiltered (well only the base station is actually connected to the line), so would this make difference on the dedicated net line, as I can stick a micro filter on these?
The other line is possibly going to be ditched along with the Sky tv package in favour of Virgin which would probably also mean getting cable internet alongside the VDSL connection, when that line is cancelled is that likely to quieten it down a bit?

I can ping up a photo of where the phone line comes up out of the ground at the front of the house and into a small grey BT box if this would also help determine if it's an aluminium line?

EDIT
Also probably worth noting is I read about ferrite cores and rings and stuff a while ago so all of the heavy power draw items in the house sit behind power surge protectors and have ferrite cores attached at both  the plug end and just before the cable goes into the extension lead or unit.
In the garage where I've got my servers and gaming rig theres an ANCIENT chest freezer that must about 50 years old that's been on its last legs for about 5 years and that's likely to get removed and thrown out sometime in the next couple of months which is horribly power inefficient so I guess this may be causing interference somewhere possibly? Or would the surge protectors and ferrite rings stop this?

[Dray]

It would be good to see your line attenuation, and better the output from the TELNET command -
xdslcmd info --pbParams

which should give an insight into the attainable speeds of your connection and see whether the BT estimate is fair.

You could do that and it won't do any harm but the purpose of the test is really to make sure the Mk3 is not reducing your speed for any reason (and if you had extension wires to remove them from the equation as well)

When the BTOR engineer was on site doing the install with his gadget thingy ma jig that tests the line he suggested a speed of around 60ish was indicated, which is why I'd guess I can and did order Infinity 2 at the time.

Unless you chose to upgrade you order fibre and specify the speed desired before the OR engineer comes..

You can filter the DECT phone but I doubt that will make a difference. Cancelling the line is unlikely to make much difference either I suspect especially if it doesn't have broadband on it.

If your Sky box is connected to your phone line, try filtering that perhaps.

But definately see if your speeds change with the home plugs removed - just to see what happens..
