Well remember that ISP providers quote bandwidth in bps. LW shows speeds in KB/s

bps = bits per second
B/s = bytes per second

8 bits = 1 byte

So 20 KB/s is roughly 160 kbps but there's also 13-20% overhead loss in speeds from what's quoted from isp's. I'm guessing you have a 256 kbps connection. Downld speeds depend upon the sources!!!
