I just switched to Mac, but I might be returning the iMac and getting a Dell or something because it's getting a little ridiculous. My IP address on my Linksys router is not being recognized by the airport in my new Imac. It took FOREVER for me to get this to work and now it has crapped out 2 times in the last 4 days. I am about to take this new Mac back to the store and go back to a Dell. Here is a basic description of what is happening: When I do a diagnostic test I click on Airport and it is saying that the airport signal is fine (green dots), but it doesn't find the IP address. I select my network name that the Airport is picking up and still nothing. I can even get online by selecting a different wi-fi signal from someone that lives close to me too. It's obviously something with my Linksys router that does not work well with my Mac. Also, even when my Mac doesn't get online, my Ps3 and 360 both still do so I know it is the computer/router that is the problem. I try unplugging the router, modem, restarting...etc. but it just seems so wierd that it goes off like that.... It's also very annoying, because then I have to hear from my wife about that we spent $1500 on a computer that won't get online some of the time, when I can still get online on my PS3 and 360. By the way, when I am not connected to the internet Safari will NOT let me put in the 192.168.1.1 in the address bar to get to my router settings. But I did check them from my PS3 and the "clone my MAC" thing is still enabled. Apple's software update tells me there's no new software available for my machine, which leaves me with no idea what's causing this or how to fix it. Any advice, solutions, or tips are greatly appreciated. Can anyone please help me??? If this is going to be a continuous problem, I am taking the computer back and getting a new Dell or something since we mostly use the computer for the internet functions. Anybody please help???
