Q: Secured wifi will not work on ibook g3

Has your iBook operated on other WiFi networks?  Do you know the exact model, so it is possible to see what the AirPort capability of that iBook might be.  Could be as simple as it is not able to connect with the type of wireless signal, that is the protocol or security format.

The last G3 model, 2003, was only capable of 802.11b if it had the optional AirPort card installed: http://www.everymac.com/systems/apple/ibook/index-ibook.html

The wireless card is not considered a user replaceable item, you would be best talking to an Apple Authorized Service Provider about that...using an AASP means that if something gets damaged in the process, Apple will not disavow helping you, even without a warranty you could want their help in the future.

You could look into something like a wireless dongle that you plug into a USB port, yes, it is something protruding from the side of your iBook, but it will give you wireless connectivity.  An option to think ab out if the internal is not feasible.

By the way, have you looked to see what is inside the iBook?  That is, go to the apple left side of the menu bar, About This Mac, More Info, System Report (or whatever the title is in 10.3), Hardware and then look for the AirPort or wireless hardware.  See what is in there (my 10.9 system has it under Network, WiFi).  But look and see what it says about WiFi, if there, what is there.

A quick search on Google turns up a lot, such as Amazon: http://www.amazon.com/s/?ie=UTF8&keywords=external+usb+wireless+adapter&tag=goog hydr-20&index=aps&hvadid=30167678317&hvpos=1t1&hvexid=&hvnetw=g&hvrand=123787172 55023154135&hvpone=&hvptwo=&hvqmt=b&hvdev=c&ref=pd_sl_iau1fjfrk_b

Usually the older iBook G3 (dual USB & colors clamshell) have a location

under the keyboard near the RAM upgrade slot, for an AirPort card. If one

is there, then the issue maybe with the protocol of the wireless base station

being too new and your iBook G3 (and OS X) being too old.

If there is a vacant slot next to the RAM upgrade chip location, then the AirPort

card is missing. A replacement is a matter of finding a working one to buy. Then

see if there is a workaround for accessing internet where you live. Most free wi-fi

locations have some security; so borrowing a Library's may be out if your iBook

ends of only working with no security enabled.

For iBook G3s that can upgrade to Tiger 10.4.11, some can see a later version

of wireless security (perhaps as fancy as WEP/WPA) however in most cases

the older computer may connect to a non-secure base station or via an older

model AirPort (802.11/b) that could share a home network by use of Ethernet

bridge, so any newer/other computer may not be at risk with an open internet.

An early AirPort Express could be used as a wireless device with a portable,

in some instances, but may not work with other brands of base stations as

a way of extended the network to just an older Mac computer of vintage.

The other option would be to use Ethernet to connect to internet, not sure if

the options there are suitable to your hoped-for purpose, or portability.

Later iBook G4 (notably) have a wi-fi and bluetooth card on the logic board

and aren't directly accessible to the user; those require a lot of disassembly.

So I would expect your G3 white dualUSB to have a location for wi-fi card.

Back in the day, there may have been third-party upgrade wi-fi cards to add

the newer protocol 802.11/b/g; those would be rare now. The USB dongle

may be a way to try & experiment to see if you could use a later wi-fi band.

If the computer could run Tiger 10.4.11, it may also be able to use a later

WEP or WPA, but perhaps not. I don't recall the 'hardware connection' there.

The early iBook G3 that uses the same wi-fi card as the iMac G3 may have

some rare third-party replacement upgrade AirPort (other brand) cards that

could be out there somewhere in old-stock or pre-owned. Places such as

welovemacs wegenermedia powerbookmedic & others may have parts.

Another idea may be to look for a later model PowerPC based portable or an

earlier Intel-based MacBook (circa 2006 to 2010) for more recent compatibility.

Good luck & happy computing!
