3 Miles is quite far from the exchange, I wouldn't hope for much.
What are your line stats like?
They wouldn't say that if you're on an upto 8MB line. If you lived across the road from the exchange you wouldn't even get 8.LadySarah said:Mine's about 2mb aswell, even though they said i would defo get 8... so annoying.
Yeah attenuation is quite bad there, line noise is OK though.bigmouk said:Noise margin (dB) : 5.8
Attenuation (dB) : 53.0
Attainable download rate (kbps) : 2656
Adam K said:5.8 is irrelevant right now.
6db is the default snr target on a dsl max line.
at night your snr can drop due to interference.
with 53db attenuation u should have no problems achieving a faster sync rate either.
i would suggest that something is stopping you sync'ing higher. are you plugged directly into the bt master test socket? are you using extension cables? are you using decent quality filters? have you got the lastest drivers/firmware for your modem/router?
depending on your router your snr can be misreported, or your router may be able to keep a stable connection at lower db levels. my router reports between 0 and 3db at night and still keeps a stable connection.
my line details :-
Downstream Rate : 5760 Kbps
Upstream Rate : 448 Kbps
Downstream Margin : 6 db
Upstream Margin : 19 db
Downstream Line Attenuation : 53
Upstream Line Attenuation : 31
also, nobody will get 8mb throughput speeds. the highest theoretical speed possible is 7.3mb due to overheads.
RobTQ said:Well you should be happy to get 2Mb as a noise margin of 5.8 would not have even got you 1Mb on pre Max broadband. There used to be a phone number you could use to find out what the cable length is back to the exchange. But of course it should have only been used by BT eng's.

sn00p said:Your attenuation isn't great (upstream is sh*te, downstream isn't brilliant) but I would have thought you would have got better speeds than that.
Have you tried the master socket and then getting the line stats?
Aberclio182 said:that just a case of plugging the router into the main phone box yeah? and taking those stats off that. or is there another way to get the stats?
sn00p said:Yes, just take the router down to the main box and repeat what you just did. At least then you'll be able to see the effects of the internal wiring in your house.
Adam K said:this issue here is the 17db snr.
it's highly likely that because of poor internal wiring, the BT DLM has upped your SNR target ridiculously high. when you first got DSL MAX were you having disconnection issues?
edit - just to add, i always thought that DLM could only apply a 15db snr target maximum, so if that is correct then have you had an issue raised with BT to have your SNR altered manually at any point?
Laingo said:Where do you get all teh snr info from?
sn00p said:He's also on the fast path, if he'd had a lot of disconnections I'd expect him to be on the interleaved path as well. The 17db level is very odd. :S
Laingo said:Ahh right. Well I used to use a Netgear modem/router.... BT said that the reason I wasn't getting my full bandwidth was because of that. So I switched to the BT hub and quite frankly it's the biggest heap of sh*te I've ever had the misfortune to use. Truly shocking.
