i have a wireless box arranged on the upstairs of my home..........its being connected to my system via a cable as similar to a landline phone

Write in a terminal
lspci
and paste the output here.

Personally, I'd get yourself a router - the router can handle the broadbadn connection - you can then use a basic Ethernet connection from there..

Or wifi...
