First you need to supply more information before we can try to answer you question, and you should post in the Networking section of LQ Forums.
What sort of network do you want? File sharing, shared printers, & internet connections, all use different set-ups.
Have a look in the Tutorials section, and a good place to start is here: http://opensuse.swerdna.org/suselanprimer.html
Be patient, and try and give as much info about your installation as you can. The more vague the question, the less able we are to answer.
