The DS Lite only has WEP. I have to run a second wireless router and hope that no one breaks the WEP and gets around the MAC address filter. Why WPA isn’t standard now is beyond me. Many consumers just plain give up on security because of stuff like this.
TiVo is doing something right by supporting WPA with its wireless adapter. After all, a TiVo is one of those devices you want connected to the net at all times.
