Yes we have to correct firmware. version 7.2.209u320943980we9fu We have had no problem with other network adaptor. I have switched the adaptors between tivos and the other tivo sees the new card just fine. Normally this wouldnt be an issue, but i am seeing that the new adaptors have better room to room transfer speed, so i was hoping to replace the wireless network adaptor with the new tivo adaptor. Any suggestions to help this adaptor work?? its a 40 hour refurb, series 2. I did a search and could only find people with wrong version software.
