[G4] Wireless Networking for iBook

[Lynn Persing]

Hello,

I just bought myself a used iBook with an airport extreme card and I 
need a little networking help.  I have two desktop G4's networked right 
now using a cable modem and a router with ethernet cables.  But, if 
possible, it would be nice to be able to use the laptop wirelessly 
throughout the house.  It's really not a priority, but if it can be done 
cheaply, I figure, why not.

Is it possible to buy a cable/dsl router with wireless access that will 
work with the laptop, yet leave my current G4's hard wired the way they 
are?  They don't have wireless cabability and don't really need it. 

I've done a little web searching and noticed that they do make a router 
like the one I mentioned above that works on PC networks, but does it 
work similarly on the Mac?  Is it difficult to configure?  Does anyone 
have suggestions for a brand of router with this capability that is 
working well for them?

I don't have the laptop in hand yet--the postman still has his greedy 
little hands on it--so I'm trying to get some preliminary info before it 
arrives.

TIA,

Lynn
