I was given an old Mac, I book , lap top OSX, 10 3.9 version, Processor is 700 MHZ power pc G3, 640 MB SDRAM
There is more information if needed
Every thing works fine I think except the wireless connection. I have a Linksys wireless G router. So I bought a Aeropad mini 802.11g wireless ethernet adapter for mac/pc, with help, programed and hooked it up, Now the wireless works to about 50 feet from router. Several questions, Is that about the normal distance from the router? Next is that proof that the airport card is bad? assuming its turned on. If so when I acquire another one ,will I be able to remove the old one and install the other (used one) with no programming, as you all can probally tell I know very little to none about computers.
These used cards can be obtained through Ebay ,Craigs list and so on
I,m told this is a very old computer for computers 2002 I think, I,d like to get it going as best I can so I can play with it and who knows some day trade in my PC for a Mac
Thak you
