is the linksys WKPC54G router and the WRT54G router the same? the linksys WKPC54G is a kit that has a router with only one antenna (http://www.linksys.com/products/product.asp?grid=33&scid=35&prid=614) and the WRT54G has two (http://www.linksys.com/products/product.asp?grid=33&scid=35&prid=601). The WKPC54G is more money because it comes with a laptop card but is there a differance to just buy a WRT54G and a wireless addapter? I am on a PC trying to get my sisters laptop set up with DSL and I am going to have 2 or more computers set up on wireless internet soon. Also can someone explain how to use WPA Pre-Shared Key or WEP Encryption and which one is better security but keeps the internet at a good speed.
