How much of a difference does it make? I'm on BT and my friends on BT, both on the same exchange. He's under a mile from the exchange, im between 2-3 miles. He's downloading at 1.8mb/s and im currently downloading at just under 300kb/s. does the distance make THAT much difference? True hes in town and im outside of town on a wee farm bit, but i wouldnt of thought that much of a difference.

Just kind of annoying when i bought Crysis 3 about 45 mins before him, i've still got 12 hours left, he's already downloaded his. Might have to phone BT tomorrow haha.
 
The ADSL signal deteriorates over distance. Basically as you move further away from the exchange the modem has more and more trouble 'hearing' the ADSL signal over the background noise and starts cutting bandwidth to keep a stable connection.

Not much you can do beyond sorting any internal wiring issues and having fibre installed if its available.
 
That speed is *about* right for your distance, nothing looks too off really. You maybe be able to bump it up a bit but its not going to be significant compared to your friend
 
That sounds about right for your line, I'm about 2 miles from my exchange and I was averaging at about 350kb/s.
 
Aww, man, thats unreal! oh well, not much else i can do. Infinity is coming this year sometime. will that be better in terms of his speed vs mine?

Chances are it'll put you both on fairly even ground if you both went for infinity. It still depends on line length but this is to the green street cabinet rather than the exchange. I used to get about 2Mbps on a 2mile (3.2Km line) on infinity i'm 400m from the cabinet and get about 64Mbps.
 
It depends on the distance from you to the green cabinet you're connected to.

From my 3mb 2 mile line, moving to Infinity boosted my speeds up to 33mb... not exactly sure how far I am from the green cabinet but I think I'm about 700m from it... although the actual cables do zig zag around the road a bit...

Might be best to check to see where your cabinet is, there was a site which I remember using which showed the probability of what cabinet you're connected to and what possible FTTC speeds you could get from it, but I forgot the link :p.

EDIT: Found it: http://fttc-check.alc.im/

Just type your post code in there, probability is the chance that you're connected to that cabinet, and uplift is the number you use to multiply your current speeds to give a good estimate on your FTTC speed. Although this is just an estimate bare in mind, it said my uplift was 6.8 but I'm actually seeing 10 :p.

Hey, sorry, sadly no infinity here yet, should be here sometime this year i think. Also no chance of getting virgin here either. checked the noise of the line...

Does the line seem a little noisey?

i done a quiet test on the line and it sounded hissy, but i cant tell if thats just the crappy phone bt gave us or not.
 
Your SNR is far too high 18.8 dB it should be around 6/7 dB if it was stable. You must have some kind of interference/noise on your line.

Also noticed your upload is at 448 Kbps, you must be on an old ADSL profile. Can you get ADSL2+/LLU in your area?

What's your postcode and what exchange are you connected too? Look here http://www.samknows.com/broadband/exchange_search

P.S. My line attenuation is 56 dB (yours is 49 dB) and I get 4.5Mb so you should getting a little higher than me on an ADSL2+ profile.
 
Snr of 10db is still too high,it should be 6-7db so you could be robbing yourself of 1.5-2.5mb of extra sync. My line for comparison has an attenuation of 44.5db and my sync is 7.8mb
