My landlord recently updated the wireless router to an AirPort Extreme. This broke functionality with an old b- or g-speed USB wifi adapter for the TiVo. He ordered a pretty standard n-speed USB wifi adapter but the TiVo said it wasn't WPA2 (if I recall correctly) compatible. Does anyone know of an 802.11n USB wifi adapter for TiVo that is compatible with WPA2 and the AirPort Extreme? Thanks!
