Two of the most popular posts on Technically Easy has to do with securing two different wireless routers: the Linksys WRT54G Wireless-G router and the D-link DI-524 Wireless router. At this time I only have those two guides available on securing wireless routers.
For those with other wireless routers, I decided to outline some of the security settings you can enable, if available, on your wireless router to make it secure.
