Mine already were. The router also comes with a mini-web server inside that administrators can use to establish settings, such as filters and blocks. For me, all the default settings were enough. But the settings are easy to change and are protected via passwords. It is obvious that Linksys, who I find makes excellent products, had the small business in mind.
Administration is very easy.
The router gives full bandwidth to all the computers no speed loss is noticeable. Having a connection that is always on is great. My 2 Macs are never fully shut down. I leave them asleep for near instant booting. Now I see differences in browsing between my computers that is mostly caused by processor speed.
