Powerbook G4 17" - airport and trackpad

Hello there,

I recently received a second hand Powerbook G4 17 inch.

It's in fantastic condition apart from one or two things.

The airport built into the Powerbook only seems to pick up my wireless when right next to the base station. Even when you take a few steps away from it, it just goes dead. I did get told this was an issue with it when I got it, but wondered if there was a way of fixing this ? ( The Ethernet works fine )

Just another issue that I have is the trackpad shortcut for expose only seems to work on one account. On the other, it doesn't. Is there anything I can do to enable this ?

Thanks for your help in advance. Any help whatsoever would be entirely grateful.

Thanks

Buy another Airport card as they do die.

Thanks very much.

Are these available in the Apple Store ? I can't seem to find one online.

There are three or four different models of 17", depends on the processor speed, but most use the standard original Aiport Card 802.11 b/g. Look at eBay and such places. Here is a starft:-
