The wireless LAN access point may be directly connected to:

A server which is directly connected to the internet (preferably hi speed). This PC (server) will configure the WLAN AP, because the WLAN AP software will be installed on this. You will be able to determine which PCs MAY connect to your Wireless Network. (security purposes)

The walls are not much of a hindrance to the signal...it is mainly distance...

hope that helps...
