"sudo periodic daily weekly monthly"

from a command line.

Then restart.

Should solve it.

I once set up my parents with a wireless router that worked fine with my computers at home. (I had upgraded.)

My laptop worked fine, but nobody else's would. It took me longer than it should have, but I finally realized I had set up MAC filtering and completely forgotten about it.

Also, I've seen quite a few G4 Powerbooks and iBooks whose airport cards, even when all the firmware and software upgrades are in place, simply refuse to connect to a WPA network. If you're using WPA encryption, try turning that off - if it suddenly starts working, that's your problem.

Sadly, there's not much you can do about it.

That's the answer, if I disable security I immediately am able to connect.

Does this mean the Airport Card is unusable and if so is there a 3rd party card available?

It doesn't mean the card is unusable - just that you'll need to compromise your security in order to use it. Even if WPA doesn't work, the inferior WEP is still an option.

Either way, it depends on which G4 laptop you have. In any case, there are a variety of USB->WiFi adapters which will work. If you have a powerbook, any number of potential PCMCIA cards also exist. In either case, you'll have to verify that the product has Mac OS drivers available, but there are literally dozens of options in either of those categories.

Am I correct in assuming that you have an old 11b Airport card and not a 11g Airport Extreme card? Unfortunately, you can't replace an Airport with an Extreme - the cards are different.

I have a Titanium G4, do you have any recommendations?

Thanks
