Wireless Router Help me Choose

I'm Trying to find the best router for me.
1. I need a router that has a Power Button Because my last one just Died with Over Heat.
2. Will there be any conflicts between the router Firewall and my PC Firewall.
3. Great Protection
4. Great Price

 

Pretty Please

 

I found one D-Link Dir 655

This router does not have a power button, and doesn't need one. It is very fast and reliable, I personally have it and I would have paid twice as much and still be happy. I love it. The protection is also top-notch.

 

What is the button on the side for. I press it and the unit just blinks is that like a bypass.
