I am really confused about why im getting files @ 50-60kbs with an 8 meg adsl broadband connection.

My brother who lives in the next room has a 1mg cable modem connection, when he downloads the same files, he gets them @ 100 kbs or more.

Anyone know what is happening here? i mean we'r in the same house and i am SUposed to have a faster connection, but it just dosnt seem to show when i use mirc.
