@ saurav
i have a tata indicom wimax connection too and i use utorrent for my downloads my torrents speed vary from 38-45kB/s

whereas when i had airtel before that i used to get speeds between 42-48

i configured the settings of my utorrent too..seeds are okay..so are the trackers..but still the seeds vary from 38-45kB/S

ill download bitlord as u say u get those speeds with it..
it would be very helpful if u could post the prefrence settings of bit lord as well
