Okay, I am a new owner of an Alu-iMac 2.4 ghz !!!!!! Installed Leopard last night and wanted to get my internet set up and . IT DIDN'T WORK !!!!!!!! The Diagnostic thing wouldn't recognize my internet. (Info for you): 1) I have an Linksys wireless router that is right behind the computer. I have to have a router for my 360 and my PS3 across the room. So I had the cable internet modem hooked to the wireless router and then to the computer. (just like it was hooked up to my PC) 2) I tried everything I could think of to get it to work. The diagnostic show that the Ethernet had a green light, but it would not let me online at all. 3) So then I tried unplugging the modem and the router and still nothing. (It gets stuck on the page where it asks "do you use a cable modem, if so please restart it and then hit continue") And still nothing. 4) So then I tried to just run the internet straight from the cable modem to the imac, and this didn't work either .. Then for some reason like a 1/2 later the network settings brought up the IP and everything and I had internet. 5) But I need my Linksys router to be used !!!! Is there any advice any of you can give me !!! I can call Linksys if I need to when I get off work, but I thought maybe some of you could help me first. I did have to call Linksys before I could get the router to work on my old PC as well, so maybe it's something with them ???? HELP PLEASE !!!! I want to love my Imac so much.
