yes and no, I've heard people having lots of problems with linksys g-router when it comes using wpa. However, wep shouldn't be a problem. Another thing to consider is the router's ability to maintain high throughput in combined mode (g + b). Most of the g-routers I tried peformed well in g only mode, but did terrible in g + b. I went through 3 g-routers before finding what I liked. If you are considering linksys do some more research on apple support forums because last time I checked, some people weren't able to get linksys in wpa to work with airport extreme. (I went for buffalo ).
