I just need a little quick/brief help on this subject.  I currently have a Wireless G router. 

 

     1.  Will a laptop with Wireless N work with that router?

 

 

I do a lot of website design services and upload/download a lot of information.

 

     2.  Does Wireless N really make that big of difference?  (...or what is the difference?)

 

 

Thanks..
