Wireless router for a 17R3

I am currently using an Alienware 17R3 with a killer1535 Wireless card. Want to take the card to its full capabilities. Which brand routers would you say are the best? Which router would you buy? Other than the Alienware laptop, there are 4 other Ipads on the wifi network simultaneously.

 

If your router is sending crap, it will sent crap to any card/device. The total connection quality may depend on both devices, but those devices function independently from each other. It's like asking about the best ice cube maker for your fridge. You may as well ask what's the best ice cube maker regardless the fridge.

Your question doesn't make much sense to me.
So I think your question boils down to "what's the best router?". In this case I'm not sure this is the right place to ask.

Edit: OK, maybe you are talking about different Wifi standards and you want the best standard supported by the card to be supported by the router.

You could get the Killer Wi-Fi with DoubleShot Pro technology, but I don't know if that's just marketing or if it actually increases connection quality.
