2 Wired PC & 1 Wireless Not Connecting

Trying to setup SOHO network with 2 wired PCs and 1 wireless laptop, all running XP SP2. Followed Microsoft Online Network wizard & Network SetUp Wizard on all machines but no luck.

Connected Cable Modem to Belking Wirless G Router. Connected Wireless G to PC1. PC1 can access internet. Connected PC2 and/or LapTop and ran Wizards. Not seeing PC2 or LapTop.PC2 nor LapTop can access internet.

Can anyone point me to the correct config procedure.
