"Keep in mind; if you want to go the free route, you’ll
only have a wired router—but you can add separate access
points. Wi-Fi support is only available in the registered version
by purchasing a Professional Activation for € 20.00
"You also lose these features for any X86 version of DD-WRT:
"USB Support. For example, you can’t connect USB drives or
printers to share them on the network.
Journaling Flash File System (jffs). Normally this would let you
store files directly on the router, such as for NoCatSplash hotspot
captive portal pages and other custom configuration.
Itsy Package Management System (Ipkg). This would have let you add
features from OpenWRT that aren’t already in DD-WRT."
