My iMac won't saty connected to the internet wirlessly. It will for a little while with full power then it will just all of a sudden stop. I know my router is in range of the computer but the the connection won't lock in any ideas?

Need more information if you want help. What kind of iMac is it?
When you say disconnected, are you losing the airport signal, or just getting "you are not connected to the internet" pages?

Intel iMacs have some issues with signal. Run a software update.
For any iMac, try changing the channel on your router. Cordless phones and microwaves can interfere with your signal.

10.4.10 seems to be breaking wireless for a lot of people. If you're running it, and it persists, you may want to downgrade to 10.4.9 if it's a problem, or stick it out for an update.
