Connect the AP121 easy to your DSL modem and you can get all your wireless devices on the Internet. In case a device is not Wi-Fi enabled, you can connect it via the integrated Ethernet port.

You can power the AP121U with an ethernet cable, thanks to its passive Power over Ethernet capability. The Atheros AR9331 chipset gives you the opportunity to install an OpenWrt firmware instead of the normal firmware. This firmware offers many customization options and functions, which are not possible with the firmware specified by ALFA. E.g. you can use the USB-Port with an UMTS-Stick.
