Powerbook G4 will not connect to WIFI

I have an older Powerbook G4 that I am trying to give to my son. I never had a problem connecting to my own wifi network before, but suddenly there is an issue. Here are some facts that will hopefully help with the answer:
-I can see the network with the laptop.
-I've connected before using my password
-Ethernet cable works fine
-My neighbor has an unprotected signal and it will connect to that one fine.
-Other devices like, iPad, iPhone, PS3, etc have no problem connecting.
-I have a Belkin with WPA/WPA2 security.
-I've tried all of the power off/on restarting stuff.
-The second I put in my password and press enter it says no connection. Doesn't even appear to search or anything.

All this stuff seems random so Im at a loss.

Also, just realized it is saying "incorrect password" which makes no sense because it is the same password that 10 other devices are using to connect as I type this.

Have you always used WPA2 security back when it would connect? What version of OSX is on the G4 Powerbook?

Have you tried turning airport on/off?

Is there any chance your wifi card in the G4 is old enough to need/be using WEP encryption. I've got a G3 iBook that does not seem to handle WPA properly.

Like dtravis7 and Slydude mentioned/suggested...I also think that the issue may be the WPA security (you can "see" it...but cannot connect).

You didn't tell us the exact model Powerbook G4 you have (there were a lot of them). But older WiFi hardware were limited to WEP security only...thus they cannot connect to a WPA password secured network.

Actually that machine might have support for WPA, but not WPA2. And that's where I think the problem lies.

As for giving your son a (minimum) nine-year-old computer -- what's the matter, don't you like him?

(disclaimer: I don't anything about your son, but let's just say I would hand it back and tell you to keep it, as its street value is probably less than $100 and it's security/practical value for modern use is nil)
