Reconfiguring AirPort

The only way you can change these settings is through the Router Utility
192.168.1.1 in your Browser check the phamplet the accompanies the router for username and password to make any changes.
Airport Admin, and Setup Assistant are for Airport Express and Extreme, these don't work with 3rd party Routers to set them up.

Do you have an AirPort Express (AX) or AirPort Extreme base station (AEBS)?

Let me clarify my question.

You state that you have a Netgear WGT624v3 which is a wireless router.


Do you also have an AEBS


or AX?


The reason I ask is that the AirPort Admin Utility and AirPort Setup Assistant are ONLY for use with one of Apple's base stations.

...we do not have either base station.

That clarifies things!

...does this mean that airport cannot do DHCP or create a NAT problem?

Your PowerBook is not doing either. Your Netgear router is responsible for that.

Your original statement/question was:

having trouble with iChat AV, and I need to check "Distributing Addresses" but can't get to it.

To do that, you must get out the Netgear's user guide and follow it's directions for accessing the Netgear's configuration page via web browser. Then you can make the changes to the Netgear router's operation.

The reason we may seem unclear with your problem, is because when you use the term AIRPORT, you must be clear as to what exactly you mean.
Apple uses the term Airport for there Wireless Technology.
This includes several different pieces of Hardware which inlude.
Original Airport Card 802.11b compliant (Older Apple Computers)
Airport Extreme Card 802.11g compliant (Newer Apple Computers)
To determine which Airport Card your Computer has, Click on your Apple upper Left then click on About This Mac. Then click on More Info and when this opens Click on Airport Card and it will tell you if you have Airport Card or Airport Extreme Card.
Airport Express Base Station.
Airport Extreme Base Station.
Next if you are using the Netgear Router that Duane showed you, then yes it will set up DHCP, and to set up any Router you use that is NOT an APPLE Product. You have to type in 192.168.1.1 or http://www.routerlogin.net
Then when prompted enter (admin) as username. Then enter (password) for the password, all lowercase.
The Yellow folded card that came with your router gives you a step by step set up guide.
Make sure your Network settings are correct.
Ethernet cable and wirelessly connected computers must be confiqured to obtain IP and DNS addresses Automaticlly via DHCP.
