Project 21
Expanding
Beyond the
Bridge
What You??™ll Need
A wireless bridge??”aka gaming adapter
Leftover nonwireless router from Project 2
Your computers with web browsers
Cost: $0
Now that we??™ve wirelessly jumped a huge span of real estate from one end of
the house to the other in Project 20, we can reintroduce wires into our extended
network configuration.
Our network continues to grow to include many computers at either end of a wirelessly
bridged network, to the new network scheme of Figure 21-1. All we need is that
old nonwireless router we removed from service in Project 2. Instead of being used as
the main expansion of our one-connection DSL or cable service, and as a firewall, we
reuse this gadget to become part of our local network at the far end of a wireless connection
configured in Project 20. All this takes is a few simple reconfiguration steps to
allow it to accept the IP address of our local network, turn off the firewall, and let it
dish out a new set of IP addresses for the extended network clients.
Step 1: Reconfigure Your Wired Router
Our first step is to reconfigure our old wired router, the one we replaced with a wireless
access point and router, to work at the end of the wireless connection we??™re making
to expand our network:
Connect a computer to one of the LAN connections on the wired router using
a single Ethernet cable. Leave the computer configured to obtain an IP address
automatically (DHCP).
