I have the same issue with a TiVo Mini V2. After a few days the remote will only work in IR mode not in RF mode. It is not next to a router. I bought a refurb a few months ago with no issue. The mini works fine in IR mode but will only work in RF mode once I loss a connection by unplugging the Miniv2, any chance tivo will do anything for me? The Mini 1.5 years old but the problem surfaced 6 months ago.
