iMac Airport Connection Issues

[Hatchet]

My iMac lately has been having a lot of issues connecting and staying connected to my wireless internet connection.

It disconnects and then connects again, sometimes going out for periods of time.

Could this be something wrong with my iMac or something to do with my router?

My router is about a year old (Wireless N)

How hot is the router consistently?

Have you checked for new firmware? (DLink especially)

Did you get any new appliances?

Did you move the computer?

Did you move the router?
