Moved house, extremely low download speed - advice please?

Rroff said:
Your download speed is in bytes per second the router sync speed is in bits per second, 60kByte/s is approx 480kbits/s (the rest is lost to overheads and that the actual speed profile will probably be 512kbit not 576).



Hes either on a banded or capped profile - hence the 576 download sync (reminiscent of the old half meg ADSL 1 packages) its not the SNR target thats pulling it down that low the SNR is high as the sync is being forced low.

With that attenuation he still should manage about 4Mbit with a good router (the DG834 being ideal for that purpose).


EDIT: I am aware I've said 576 when his router is showing 575 - the DG834 incorrectly reports it as 575 the chances of it being coincidence is unlikely.

EDIT2: Advice is the same tho phone the ISP up and ask them to reset your ADSL profile, although if its a new connection and you've only been syncing for a few days, depending on what system the ISP uses it might automatically rise over the next few days or it could be possible BT have manually set it to that profile due to issues with the line.

Thanks for the advice. The connection isn't new, it's about a year old I think, but I moved in a week ago and it's been the same as it is now. Going to give them a call now.

Your wrong mate it's the broadcom chipset on the billion that is reporting the wrong attinuation.Mine is 58db reported by a bt engineer doing a line length test but the billion reports it as 63.5db, it's something to do with the way the chip reports/reads it

According to this graph im right.

My attenuation of 60db gets me just under 4mbit which is what i get.

The netgear use to report 51 which would easily get me over 4mbit which has never ever happened in over 7years.

If you use a bt2700hgv bt business hub that wil give you the correct attenuation @300kHz,mine being 57.5db but the billion reported 63.5db(if you google it there is quite a bit on the Internet about broadcom chipsets reporting higher attenuation)

Some netgear DG834 use broadcom chipsets, but some don't so its a bit confusing. My DG834GT reports the same as the engineers line test tho for attenuation.

It's the broadcom BCM6358 chip that does it,if I remember correctly the gt uses the BCM6348


The dg834 versions 1,2,3,5 use the Texas instruments chip and the dg834 version 4 and the gt use the broadcom chip

Looks like my ISP have reset the ADSL profile:

Quite a bit of an improvement. Thanks very much for the help everyone.

It's still slow at downloading, but not as slow as before. :p
 
now, have you thought about a new filter looking at wiring etc.? adslnation does a nice filter that attachs to front of your socket if it's a NTE5. About £15, would improve it again a little bit I reckon

I don't know anything about filters, but I'll look into it. I did try taking off the filter and plugging the cable directly into the test socket which seemed to make no difference though.
