I got LA FONERA.
So far I used in my room my Linksys WRT52GS with LA FONERA firmware installed, but it had only one SSID and I needed to be authenticated every time I wanted to use WiFi in my room.
With LA FONERA, you can use two SSIDs, for a FON access point to the public and for My Place, a WPA-protected area for private use. Now I can enjoy wireless connection with my laptop or Nokia E61 handset without logging in to the WiFi access point every time I use it.
