Contrary to suggestions on many web sites, including Motorola's, this unit does not support Wi-Fi Protected Access (WPA or WPA-PSK or 802.11i) security -- nor is there firmware available that enables it. These days, no 802.11g product should be on the market without at least the lowest level of WPA - WPA-PSK TKIP - available. WEP, even with a 128 bit key, is simple to crack with downloadable tools. This is a show-stopper for my network and it should be for yours too. It's going back to the place of purchase.
