with your current attenuation and noise margin already at 4.4db I can'tsee you get much better than you have - about 1mb

I'm not a techy so don't understand a lot of the numbers but I certainly had a faster speed with my previous provider.  The speed test was only giving a figure of 0.32 Mbps whereas I used to get closer to 1.5Mbps.

Hi your download speed cannot exceed your IP profile

Hi John, As I said, I'm not a techie so I don't really understand the numbers.  But looking back at the speed test stats from my TalkTalk days, my IP profile was quoted as  1250Kbps (which I assume to be 1.25Mbps)  With BT it was 0.5Mbps yesterday & is showing as 0.75Mbps today (with a D/L speed of 0.43Mbps).  And even if I don't know about the numbers, I know that my internet is a lot slower.  I used to be able to stream BBC Iplayer (just) but now can't run more than about 5 seconds at a time.  As far as I can see, the only thing that should have changed substantially is who I'm paying my bill to.

you have to remember, that you're line speed can vary as the service is rate adaptive. it is very possible that the external line has degraded in parts causing your speed to drop a tad. on shorter lines you really wouldn't notice a speed difference, but because you're on a long line every 100kbps or so really does count and you notice the difference. you could also try a bt business hub one of the older versions which have a good rep on lengthy circuits.

the reason for the speed difference between Bt and your old provider is that Talk Talk they are an LLU provider meaning they have there own equipment in the exchange and it was an UP to 20mb service with BT you are on an up to 8mb service

cpf has said his ip profile was reported as 1250kbps which is a bt ip profile, tt don't use ip profiles j mate 😉

So does this mean that an 8mb service can't supply 1.25mb but a 20mb service can???

Don't know about that but TalkTalk directed me to the exact same speed test site which is where the numbers came from.

different types of network different settings

[astar27]

it's marketed as different on different isps, basically with bt everything on adsl is marketed as up to 20mb, but there are two variants adsl max (up to 😎 and adsl2+ (up to 20). whereas with tt they are marketed as up to 24 but it's still adsl2+ and works in the same way, with the throughput being around 85%, i think its 88.2% for bt and 87% for tt.
