my download speed; wanna help?

can anyone help with my sky broadband?
i'm use Sky Broadband Unlimited.
I apparently get a downstream of 4095Kb.
I'm new to computers so i might be missing something obvious.
When i use the speed checker on this site it says i get 3.2 megabyte.
When i actually download something the most i get is about 450kb.
Why is this?
If anyone needs any info just ask

Post your router stats.

Don't you mean that the TBB speadtester says 3.2 Megabits ps?

And are you sure that when downloading, it doesn't say 450 K Bytes ps? Cuz that's about right for 3.2 Mbps!

Type Interleave Path
Status SHOWTIME

Downstream Upstream
Data rate(Kbps)

Output power(dBm)

Attenuation(dB)

well if this is correct, could i change it? because for downloading it takes forever compared to my mates internet

You haven't answered my Qs. Post copies of the actual readings that you quoted to show you haven't mixed up your units as many do here.

You line is capable of 8 Meg sync. Have you just joined Sky? Cuz they start you off on 4 Meg.

i may have mixed up my units.

Speed Down 3266.55 Kbps ( 3.2 Mbps )
Speed Up 647.00 Kbps ( 0.6 Mbps )

when i download i get between 400 and 470kB/s

well i've been with sky a few years, how do you know what my line can handle can i ask? any advice would be welcome, the download speed is pathetic

Your throughput is correct for your Sync (usually about 83% of Sync) assuming you are measuring your downloads in Bytes. However your Sync is running about 50% of expected. See here: http://www.kitz.co.uk/adsl/max_speed_calc.php

my router isn't on there? so how do i get 100% if thats what i need?

You asked me how I knew what your line should do, No router is required! Just feed your Downstream Attenuation of 42 into that page.

Your attenuation is 42
