But suggest checking if the g5 has a wireless card installed in it first before buying a dongle.


you may have an airport extreme card but if it does not have one see link below

Thank you for contacting Fixya Support, I am glad to assist.

Depending on what type of Internet service you are using, your Intel iMac comes standard with an Airport Extreme wireless card built in. As a result, if you are unable to connect wirelessly to the Internet, you will need to try this:

- Click on the Apple menu icon, located in the upper left corner of your screen and select System Preferences from the drop down menu.

- Now locate Network from within System Preferences.
- In the side window, make sure you see Airport and check also to see that it is turned on. If it is, then check the left side window to see if the AirPort connection is active.

Keep in mind, your modem or connection router of course, has to be able to provide wireless connectivity, otherwise, if you do not, there will be no need to try connecting via your AirPort Extreme card.

If your network has been physically set as a wireless network, then just turning on the AirPort card in System Preferences>Network will start discovering all networks within its range, including your own network.

So whether you are using an Airport Extreme, Express or a 3rd party (non-Apple-branded) router, you should be able to connect wirelessly.

If you are still unable to connect with these basic steps, here are a few articles you will need to review from Apple Support informational database:
Requirements for wireless Internet access with AirPort
Airport & Bluetooth interference (for connectivity issues)

So here are some basic steps and resources you can try.

If you have more questions please feel free to post a comment.

I hope this information helps.

Try turning off Airport. Your computer may be finding a wireless network and automatically switching to it, and getting an intermittent signal. Just a guess, but for a good ethernet connection you want to disable the Airport searching feature anyway.
Open the System Preferences application, select "Network" and right on the top left of the resulting window there's a pretty big button that will either say "Turn Airport On" or "Turn Airport Off" - just turn it off if it's not already ...

Hope this helps!

For help with Public Address Systems see my new How To Video, available as a DVD at www.whamuniversal.com

Try with Safari or Firefox. If still no pages loading then your Airport is not connecting to the Internet. If you are using a cable modem contact your ISP for assistance.

did you try going to printer properties? i think you will most likly find your answer there.

Depending on what model clamshell you have will determine a few things. One thing to take into considertion is does it have an airport card in it already? I know it does not have USB 2.0 so a dingle is going to be super slow. 
The original apple airport cards that went into most of the computers before like 94 or so are the same and will work in your machine too.
Getting to it is a little more of a chore. go to iFixit.com for a detailed directions to install it and they also have items like this for sale. Check on eBay for a known good working pull apple airport card delivered for not more than $75.

The OS mac osx has the drivers installed on it to support this device so does OS9

Most likely you have a software problem with the OS X software itself, reinstall the OS it should take care of your problem.

Yes better get a new wireless card if there's a airport that can be connected via USB that will be better..

Good luck....

well imac G4's don't  have built in airport (wireless internet) included as usual with apple its another item you must buy an airport extreme card  then hook it up to an airport base station another item to buy via wireless internet then hook you airport extreme base station up to your modem via ethernet. whew ok now sync the airport base station to your imac using airport set up application then select your network and type your WEP password and viol internet in about 1 hour if your lucky hope this helped my fingers hurt now LOL.
