Whats the most i will get on these?

For those who cant be bothered to look https://www.cableforum.co.uk/images/local/2005/07/7.gif

Line attenuation
Down 55db
Up 15.5

Noise margin
Down 25db
Up 24db

Thanks
Fastest speed what? I take it you are wondering how fast an ADSL speed you can get on your line. I would think it would be a lot to do with how close you are to your nearest enabled exchange. Do you have that information too?

Distance irrelevant, SNR and attenuation far more relevant as they indicate both line quality and line length.

Now as I told you before Angelus you numpty I reckon you'll manage 4Mbit but would be VERY surprised if you got any more than that, on the other hand I also reckon your router is wrong about attenuation, no way you're 55dB downstream but only 15 upstream, 15 upstream puts you about 1KM from your exchange, so it might be wrong about SNR too.

Ask UKOnline to put a manual 2Mbit order through with BT, show them your line stats which indicate 2Mbit will be fine, and if they do actually do it and BT are feeling nice 2Mbit will be yours, then when we see what impact the extra 1.1Mbps of ATM rate has on your SNR we can revisit it.

I reckon it'll drop a fair bit as you'll have to start using spectrum which you aren't at the moment, which won't be as clean as the spectrum you are using to achieve your current 1.152Mbps synch rate (DSL works on 255 x 4.3125khz bins, the higher frequency bins will be more heavily attenuated so signal will be weaker on those - you're probably using low ones at present and being forced to use higher ones will drop your SNR margin a fair bit).

Also I think you'll find I pwn you dude :)

Noob i asked this before you answerd me.

And you will never pwn me you welsh wannabe :D
