IMac G5 24" NO INTERNET contacted Apple

Question

Hi all,
I have just got a new IMac G5 using 10.5.2as a wedding Present and set it up etc. Connected to my wireless network ADDON GWAR3000. Found it no problem. GREAT! But it said it ws connected with a Self-assigned IP address. Clicked Safari... No internet. As per a lot people here i think there is a common problem with Lepoard and Connecting to a wireless Network.
I have a G4 Graphite which is on 10.4.11 and uses tge same wireless network. No problems at all. But now using this as a Target Diskmode for my IMac.
I contacted Apple today to try and get something resloved. Went through the usual tick boxes to try and slove the problem. Finally i was told to use the install disks to Format and re-install the software.
This has now been done and guess what.... it didn't work so still no internet. I have been given a case number and a person to contact. So my case is kind of being dealt with.
Can anyone else help at all with Lepoard and connecting to the internet?
PLEASE ANYONE SOMEBODY HELP US ALL GET ON THE NET USING THIS SPOTTED CAT OPERATING SYSTEM

Answer 1

Almost certainly misconfigured networking.
Click on Apple Menu/ System Preferences/ Network.
To the left you will see a window showing all your potential connection resources and below 3 buttons +/- and what can only be called a cogwheel.
If you are not going to need ethernet/bluetooth or fire wire highlight each in turn and hit the minus button to delete them (they can be restored if necessary). I would however leave the ethernet and of cause your airport in the panel.
If the airport is the lowest of these in the panel you need to move it to the top.
Now heres an anomaly for some reason Apple have abandoned direct drag and drop ! You have to click on the cogwheel and choose Set Service Order. A new window opens and you CAN drag and drop in this to change order (MOST UN APPLE imo) Place Airport to the top and click okay.
If you have limited connection their will be a yellow spot to the left of Airport in the window, Red no connection or Green for full connection.
The name of the network should be shown in the pull down menu in the centre of the main window.
Right now for some settings. I suspect that your router should be supplying the IP addresses on the network ( This is normal= The router can randomly assign addresses or be set up to assign static addresses if you want).
If your computer is assigning a self assigned address the router is NOT in-charge so won't pass you any information simple as that !
Right now click on the advanced button in the lower right of the main window and click on TCP/IP button( second button along) in the new window.
There are two pull down menus you can change here.
The top one Configure IPv4 is the most important and where I believe your problem lies.
You need to turn off your computers ability to give itself an IP address . In this top button i suspect it is currently saying manual or even off. You need to change this to using DHCP thereby passing the responsibility for Ip address allocation back to the router.
For the second menu for IPv6 leave as automatic.
Now click on the renew DHCP lease button and if all is well the router will find and give you an IP address.
Click the Okay button and you return to the main Network panel the spot to the left of Airport should now be green - Good to go!
You should now have full access however if not then the router will also need configuring as it MAY have MAC address filtering or other security enabled.
If this is the case you will have to reconfigure the router as well to add your computer to the accepted list on the router.
If this is the case come back here and i'll try to help.
