Have the PC with the internet conn. share the conn. That'll give the other PCs connecting to it the IP address and gateway info they need to get on the net. From here, bridge the connections from the LAN to the internet. Then, have the wireless router use WPA security. It's more secure than WEP. If you can, configure the router to allow only included MAC addresses.
