can't connect wireless to internt
I have a 2003 powerbook g4 12" AL. with panther mac OS X 10.3.9, with airport extream, a u-verse 3600hgv router. it has other wireless connections but I have to use ans ethernet cable to connect, I'm not a mac user, I got this from my daughter so I know I'm not configering it right, anybody know how to do this?
I'd like to get it to work so my grandson will have a laptop he can use.
PowerBook, Mac OS X (10.3.x), works great, in good shape
