ok I have a wired router connecting my desktop to the cable modem. I just got a macbook and now I want to set up a wireless network, so i went out and bought a wireless router. So I want to set up a wireless router to use my mac and ipod touch around the house.
1) Connect a computer to the router via an ethernet cable. go to 192.168.1.1 in your browser to enter the router configuration menu. Find the setting for Wireless and make sure wireless is turned on.
2) Connect the ethernet cable from the modem into the router.
3) Restart both the cable modem and the router.
4) On your mac, go to sys prefs->Network->Airport. You should then see your wireless network.
