It's winter, and the air is dry. Could electrostatic discharge have fried something? I'm not familiar with the Electroline adapter. Does it even have any active components to be damaged?So I bought a new receiver (a Pioneer 1021) and since I had to recable everything anyway, I thought I might as well unplug everything, clean, etc. So I did that then started putting things back together.
From the wall, I had the RF cable going into an Electroline two-port amp, with one output going into the cable modem, the other into the Tivo tuning adapter. I plug the modem/router in first and everything's fine. But after rebooting the TiVo, I get the "searching for cable" error -- it can't see the cable in. I try switching the output cables -- the modem connects using the TiVo's cable, so it's not the cable. I try going directly into the TiVo instead of the TA -- doesn't work. I take the TiVo to another room and try the cable directly from the wall -- it works fine. I take it back to the living room and try again -- still no joy. (I am using the exact same cables as before, after trying brand new cables first.)
Finally I try an older Electroline adapter with way more ports than I need, and voila, it works (though my signals aren't quite as strong as before). I have no clue what might have gone sideways here. Any thoughts?
