you can't just say: it don't work, how do i fix...well, you CAN say it
but we can't fix it by guessing:

did it work using the live CD?

did it work during install? (there is a place, as far as i recall) to
check networking during install..)

did you, during install, elect to update your system? (that is, was
there a quite long period of downloading, unpacking and installing
from online sources)

when you say "wired connection" what do you mean? that is, is your RTL
8101 plugged into a cable box, ADSL modem, router, outlet built into
the wall or what?

did you, during install, elect DCHP?

if router, have you configured the router to let you in?

do you need to adjust your (or your router's) firewall?

give us some hints, please..
