Solved MY issue...maybe it will help YOU too.
Well I am not going to tell you that my solution will be yours, but here goes...
So after visiting a coffee shop with free wireless to confirm that it was, in fact, the computer itself, I learned just the opposite.
The Powerbook G4 WAS able to connect with their wireless.
So now it was back to the ISP with more questions.
It turned out to be a simple, yet elusive, solution.
My ISP is AT&T u-verse. The wireless router is an EWIRE unit that handles television and internet. It has wireless, coaxial and ethernet connection capability. It handles three three TV's by hardwire. It is also linked with a PC laptop, an iphone and a PS3 with no issues. The G4 laptop and the AppleTV were having problems.
Turns out that, on restart, those two units were dumped. The system was asking for the WEP-password. There are two number sequences on the unit itself. Although mine are default-assigned, they can be changed.
One is system password-which is the obvious choice. But what I NEEDED to use was the WIRELESS NETWORK KEY. when it was asking for password, I got misled.
And that solved everything immediately. We're fully up-and-running.
I hope it helps out at least a few people with this issue!
