Advertisements There are probably threads on this but I'm just not finding them. I have 2 series 2, both of which I have had for years. They are networked and have been for years. I haven't changed anything. Yesterday one of the units stopped seeing the other. It still works, still connects via network to TiVo, indicates that the network is fine. Looked online and transfers are still enabled for both. Yesterday I forced a connection and, after that, for awhile it saw the missing unit and I was able to transfer programs. While they were still transferring however, the unit again disappeared from the list. Today it was still missing. I restarted the naughty one and it currently sees the other and I am able to transfer. Any ideas about what would be causing this?
