Router not available after about 5 minutes

Hello,
Have a Netgear N600 router. Works for about 5 minutes and then is no longer available. What's the problem?

Based solely on the information contained in your question I'd say that the router simply gets tired after 5 minutes and takes a nap.

Seriously, you want help you have to provide some details, we're not psychic here.

Desktop or Laptop?
Wired or wireless?
DSL or Cable?
Router configuration?
