Windows 7: Internet Connection Sharing

Hi all ,
here is the scenario :
I have 2 laptops A and B
A is connected to a broadband connection, so my purpose is to give B internet connection.
My question is :
If I connect A and B to a wireless router then I share the broadband connection on laptop A using ICS , will this work??? and can i have printer and sharing on both in the same time ???
I didn't try this , because i would like to have an answer before buying the wireless router....

If you connect A and B to a wireless router, you have no need for ICS. The router will provide the sharing if internet access.

Yes, you can have printer sharing on both at the same time, folder and file sharing too if you want.

I forgot to mention you that the wireless router will not have access to the internet physically , it will be used as wireless switch ,because i don't want to use Rj45 cables..

Yes, it should work. Just configure your router to use Laptop's A IP address as a gateway.
