WIRELESS CARD SET UP

My laptop has got the following wire and wireless cards: CLEVO/KAPOK RTL-8169 Gigabit Ethernet Configured with DHCP. Intel PRO/Wireless 2915ABG MiniPCI Adapter Configured with DHCP. We could successfully connect to the wire network although we were not successful with the wireless connection here at FNAL. Since all laptops running Windows can easily use the wireless network in here, we are wondering whether we are missing some parameters setup in the card configuration procedure. Please, can someone help with that ? Thank you in advance. Maura
