How to set up a WLAN station using dial up connection

I recently received a HP notebook 110 which has a WLAN setup ( I believe this is WiFi). At home I use an older computer, a HP a1000n Pavillion with a 56k internal modem and MSN dialup. Is it possible to set up a WiFi station so I can my notebook can access the Internet? I am posting this here because the notebook using Windows 7, though my Pavilion uses XP. If this is the wrong area, please...
