I just updated the OS of my first generation Imac G5 to Tiger. Now it will not connect to my wireless network. I have an airport card in the Imac annd am using a d-link DI-624 router. Although previously the connection had been sketchy, now it will not connect at all. Any advice on what I can do. One time and one time only there was a message that said something about a firewall and that the OS was determining the IP address and might not be able to connect. Does that vague description help anyone out?
I have an iMac G5 with OSX Tiger, and connect wirelessly to a Linksys router. So, maybe I can help. Here are some ideas…
Do you have an AirPort Status icon on the upper right of your screen? If so, how many black bars does it show, or are they all gray? This shows the signal strength.
Unplug your wireless router, wait about 10 seconds, then plug it back in. If you have a DSL or cable modem, do the same to that. Sometimes this will help reestablish a connection with your ISP.
Go to the ‘Network’ section of system preferences. Here are my settings…maybe they’ll help.
Under the AirPort section, I have “By default, join:” set to “Automatic”. “Show Airport Status” is checked. Under the TCP/IP section, “Configure IPv4” is set to “Using DHCP”. On this tab you should be able to see your IP address. Mine is 192.168.1.100. What does yours say? If there isn’t an IP address, you can click the “Renew DHCP Lease” button.
One last question…are you able to connect to the internet from the iMac with a wired connection?
I checked all those things, and they seem to be correct. In the midst of sweating bullets trying to get the thing connected, it suddenly started working again. It is the only computer my wife will use, conveniently located in the kitchen. I installed Tiger over Panther, going against my thoughts that if it ain’t broke don’t fix it, and without her consent because I thought she would like the widgets. Then this internet thing happened. What really bothers me is the message about the firewall, and the fact that the OS is picking it’s own IP address. Why would it suddenly want to do that?
If the error happens again, if you can write down the exact error message, I’ll see if I can figure out what’s going on.
But, if the IP Address message is just referring to DHCP, then that is normal operation. I’ve never seen a warning message about the firewall before. Let me know if that comes up again.
