Before I call o2 can anyone check my line stats?

Hi everyone, firstly I would like to appologise for a thread on line stats.

Reason is I moved from virgin media cable (20mb) to adsl when I moved out of my parents house and it was the only option where I now live.
I'm used to the speeds it offered so would appreicate if you could comment on the line stats to see if they are the best I am likely to achieve.

It's a new build house so no ringwire etc. and the router is in the master socket, which I fitted myself as BT wouldn't send an engineer to fit as the wiring was already in the house.

I'm on LLU on the upto 8mb package and according to samknows 3.7km from the exchange.

xDSL linestate up (ITU-T G.992.5;
downstream: 2821 kbit/s, upstream: 991 kbit/s;
output Power Down: 16.5 dBm, Up: 12.0 dBm;
line Attenuation Down: 62.5 dB, Up: 34.5 dB;
snr Margin Down: 6.5 dB, Up: 6.5 dB)

Cheers
 
looks like you are on a long line there: downstream: 2821 kbit/s, upstream: 991 kbit/s;
i would say that the best you are going to get from that!
 
A better judge of how long your line is would be your attenuation - it's either ~6km long or made of wet string.
 
llu should be adsl2, so considering the sharper drop at the high end and you snr, you're not going to get any better unfortunately.

Also samknows measures as the crow flies, I'd say if you were to trace the route of your telephone line it would be closer to 6km (estimate based on stats)
 
Ok thanks. Only other option is moving then or picking my house up and moving it closer to the exchange haha
 
You may be able to squeeze a little more speed out of it, usually in the morning you may see the SNR margin go to 7dB or 8dB if you reconnect at that time the speed should increase.

The downside though is that in the evening if your SNR drops below 2.5 the router may reset and you will lose connection and when it re-syncs it may be even slower.
 
My evening snr is 1.5m, <3 broadcom, although I've seen a broadcom router hold a line registering at 0 db. If your router is resetting at 2.5db it's simply not up to its job, crashing under load from fec. Some handle it better than others of course. My old dg834gt would crash at about 8pm while (ironically) the thompson box be sent me works fine.

As for the op I'd fit a filtered faceplate (if you haven't already) like the XTE-2005 and pair it with a shielded rj11 (Belkin), ignore the blurb, it's basically cat5 for your phone line. They may(/may not) improve your sync but reducing the errors allows you to lower the snr a squeeze a bit more out.

In any case they're cheap and generally quite effective, although an snr of 6 on that line isn't bad at all.
 
I reset the router this morning at 7am and the stats are very similar.
Will look into the filtered faceplate, as its just a standard master one at the moment. I've not seen the snr fluctuate and not noticed the connection drop once its always been at 6.5.
The line is stable just would like some more speed, i accept it may be not possible but anything is worth a try. Cheers

I'm not sure but at one time I think you could change the SNR manually but it depends on the router and ISP, I think you need some software to do it as well.

If your SNR never changes It may be possible to get your ISP to change it but not all will because they don't want people continually messing about with it.
