I am looking to this from two points -- a home user with limited to no funds and a corporation with security funding.
Even in home WLANs, variables prevent a "one size fits all" solution. Some cable/DSL users start with a green field and can purchase any kind of wireless router. Others begin with the broadband router supplied by their cable/DSL provider and must make the best of the security features embedded in that router. Some home users only require Web browsing, while others need support for online gaming or VPN clients that connect them to corporate networks. Security implications differ in all of these cases and so do the "best" solutions for each.
That said, WLAN security "best practices" can serve as a starting point for home users and corporations. To learn more, listen to this pair of SearchSecurity.com webcasts: Locking down your WLAN: Part 1 -- Identifying the threats and Locking down your WLAN: Part 2 -- Implementing Countermeasures.
