each person has there dis likes and likes of a product
i prefer d link and linksys products for home use.
as for getting the same brand some claim that some wireless card wont work with some routers. you just need to make sure any kind of wireless product you get is Wifi Compatible and you should have any problems with mixing hardware.
i have a linksys G router and an Orinicoo card that works perfectly together.
WAP has taken on a new meaning. WAP (Wireless Application Protocol ) does not stand for wireless access point any because of the new encrption that has taken WEP place.
you would use a wireless access point when you have an all wired network and you want a simple solution to add wireless.
most people who already have routers usually just get the access point because sometimes they are cheaper than a whole new wireless router. (sometimes)
which standard were you thinking of using? A? B? G?
