Trouble & Confusion connecting my laptop

Hi, I already have a modem & internet connection for my desktop computer. Now I just got a gateway laptop with Windows XP (model 400SD4) off my friend and want to set that up to connect to the internet. I tried calling my internet/phone company for assistance on setting it up, & after a few of their attempts they told me I needed to get the proper wireless LAN drivers installed. I have no idea what to look for, I included some screen shots of whats going on, when I go to my device manager, I have that yellow exclamation point under "other devices" Notice it says Wireless_LAN_11Mbps_Mini_PCI. When I click on the properties, it tells me the location is "on Texas Instruments PCI-1410 CardBus Controller". I'm not sure where to go from here... I cant really find what to do next, or where to find what exactly I'm looking for. I'm guessing I have to update or install new drivers or something. How do I do that? Any help would greatly be appreciated.
