New iMac: compatibility issues with wireless router?

[Tarolisol]

I had the same problem with my new MacBook. Do you know how to connect to your router? If you have another computer connect to the router and there should be some security features you should be able to change, or you can manually put in your computer ID number and you should be able to connect. I dont have my mac on me at the moment, but if you cant figure it out through the router menu ill help you out tommorow.\ if you need.
