Hi Roxy.

Unfortunately, you're quite a way from myself and my network access doesn't stretch that far. However, if you wanted to, you could PM me your telephone number and address (with postcode), and I may be able to dig a little deeper for you in relation to true distance from Cab, etc.

I've done this for lots of our members, and Kitz would hopefully attest to this ?

Was your speed estimate 80/20? as you stated you was estimated that.

Hi Chrysalis,

Yes, based on our telephone number, BT and the DSL line checker reported us at 80/20 over a clean line.

What made you estimate 52? or was that the actual isp estimate?

-Various VDSL distance charts show 50mbps is attainable at distance of 500 meters.
-The engineers we had out said they were confident the actual cable length was about that long.
-Additionally, because of the problems we were having, I started doing my own research and decided to do PSTN checks based on my neighbours who were showing the ability to achieve around 50mbps or great(however now knowing there may be a serious fault in the cabinet, who knows what the real numbers are).

What do you mean by 'maximum data rate to cabinet'?

In the Home Hub 5 router stats it shows 'Maximum Data Rate' which has been explained to me as the maximum 100% theoretical sync rate to the cabinet at any given time.

Now based on the info I understand.

24db attenuation for FTTC does indeed I reckon suggest around 400m, so it suggests something up with the cabling.

Yes, though I was being a bit conservative and going with the engineer's 500m claims as mention before.

As a comparison on google maps I am about 200m from my cab, openreach support told me my line length is just above 400m (if I remember right I lost the email) and that has my modem reporting overall attenuation of 24db.

Can you post the pbparams that show attenuation for each seperate channel e.g. here is mine

                  VDSL Port Details               Upstream                Downstream
Attainable Net Data Rate:           30899 kbps              73372 kbps
Actual Aggregate Tx Power:             5.9 dBm               13.6 dBm
====================================================================================
        VDSL Band Status                U0              U1              U2     U3               U4              D1              D2              D3
  Line Attenuation(dB):  1.5     12.9    26.7     N/A     N/A    9.7     22.6   35.7
Signal Attenuation(dB):  1.5     12.8    26.6     N/A     N/A    12.2    22.4   35.7
                SNR Margin(dB):  11.9    13.4    12.9     N/A     N/A    6.4    6.4      6.4
                 TX Power(dBm): -4.6    -27.6    5.5      N/A     N/A    10.7   7.3      7.4

so my 3 downstream are 9.7     22.6   35.7
if yours is similiarly I would be very interested to see your hlog, snrm and bitloading graphs if you can get them as your line appears based on your attenuation and supposed 80/20 estimate to be way under performing.

I would love to however these home hubs no longer support any of that level of stats or details.

FWIW, I'm around 1100m from my cabinet & the single DS attenuation value reported by the HG612 is 24.9dB.

This is this morning's pbParams data from my connection:-

yeah sorry I wasnt paying enough attention, mine is reported as 14.8db not 24.  So yeah the OP's line is way longer than 400m, I think nearer to a km.

Given BE has similar attenuation to you it would suggest your speed is reasonable if we assume he is a reasonable benchmark.

The question remains as to why you was estimated 80/20, the answer may be what Black Sheep said in another thread about DP's been long distance from properties in some areas.

I can confirm that BS is bona fide and its ok to give him your details if you wish.
 
I will however say to anyone else reading this,  please only PM him details if the request is initiated by him.  I dont want the poor guy to be deluged and he may not always be able to help.  He reads most posts, so if he feels he may be able to help the invitation will normally come from BS himself.

I would love to however these home hubs no longer support any of that level of stats or details.

Do you feel up to the task of unlocking a HG612?   These can often be obtained fairly cheaply on ebay and its a case of installing custom firmware on them.  They are much easier to hack than the ECI's  and theres a brief outline of what you need to do here http://www.kitz.co.uk/routers/hg612unlock.htm

If you want help such as just checking you are buying the right modem or which firmware to put on.. then just ask, theres plenty on here that know how to do it.   I would recommend that you open that as a separate thread though, just so details about your line fault and unlocking the modem dont get all mixed up together

It shouldn't be that much longer. I surmise there's an issue at the cabinet(Well we know there is, just not what type) that's contributing to increase cable loss and resulting in higher attenuation.

I was estimated the 80/20 profile because BT records had our fibre at the wrong cabinet.

I all ready have a ECI OR modem on the way. If it turns out that having a dedicated modem helps keep the connection stable I might swap it for the 612.

Does that mean I will have to stop putting 'Black Sheep' as my named engineer?

Ha ha ......

How come I can't ever get one of those awesome knights that people rave about, that come around with a smile on their face and a real interest in making this better for you? Do they only exist on fabricated threads on BT's forums?

I assure you that they do exist . . . Black Sheep, for example and before he moved to the US of A, Ezzer. 

[Black Sheep]

Thank you B*Cat. As I'm sat here typing this, I'm also in communication with an EU who is suffering from REIN issues. Spent a while earlier today showing her the 'KITZ REIN' site and explaining in layman's terms what it is etc, then took her for a drive to an area that has known REIN for her to listen to.

It is only prevalent between mid-evening and morning, and trying to get a PTO to attend site would be nightmare-ish. So, here I am assisting from a distance. TBH, I think she's cracked it .................. just awaiting another text to confirm ?
So, we are out there .... 

 

[Roxy]

ECI modem here, going to wait to install it though. Max rate has dropped below current data rate, so don't want to reconnect at lower sync. I appreciate I'll lose any stats moving forward.
