why does my router n?

Your laptop needs to support N and most likely it does not.

What you have is an N router and a G adapter. The N router is backwards compatible, so it works with G devices, but at G speeds

For you to get N speeds, you must have both pieces of hardware match

So you need an N adapter and an N router

Yeah you need a wireless N enabled card aswell as the wireless N enabled router for it to work at full speed.

This is your problem...your laptop has a wireless adapter that is only G compatible, you need to purchase an N wireless adapter for your laptop.

Hello!!!!

I agree with 2nd answer. You need get N supported wireless card. I usually shop at cisco shop: http://ciscoshop.internetworkplanet.com/

Here you can get N supported wireless card at reasonable cost.

Good Luck...
