I have been away thats why I have not been posting much hehe
but yes a wireless router and a wireless card in laptop will let you connect.
All you do is when you get the router is type in the gateway ip for the router, set up your broadband username and password, enable wireless, enable wireless security (VERY IMPORTANT!!!!!) WAP/PSK is more secure than WEP, go to laptop, scan for wireless networks, locate yours, type in wireless WAP/PSK key (one you made in router settings page) and hey presto your connected.
