How to automatically join a wireless network?

[btcomm]

I can join the network but how do I get the mac to automatically join this network all the time?

System preferences -> Network -> double click the Airport item.

In this window, select By default, join: Preferred Networks

Click the options button. In the dialog, make sure "automatically add new networks to the preferred networks list" is checked and set "if no preferred network is found..." to be either "keep looking for preferred networks" or "automatically join an open network."

For me it does that all by itself. Does the network have a password and if it does, did you check the checkbox to add the password to the keychain?

I have a 2wire home portal, I selected prefered networks and selected the 2wire. Everytime I reboot the airport icon is gray again, I click on the airport icon click on the 2wire and it works. Why do i have to keep clicking it???

I made a new network location and with airport only and it still does the same thing.
