Where I live the landlord had been using a g-speed wifi router with a g-speed wifi adapter for the TiVo 2 in the house for several years. We recently upgraded to an AirPort Extreme and it's been great, but because of the default network security type the old TiVo-compatible USB wifi adapter won't work with the new wireless router. Does anyone know if an n-speed USB wifi router compatible with the TiVo 2? Thanks!
