I am not farmiliar with Mandriva but in the control panel there you will see a network & internet icon that will allow you to set up your network card(s). It really should be plug & play, you might want to try all of the options you mentioned in your e-mail, to see if Mandriva will detect  and set them up for you, If not, you may want to google around or ask for further help.
