We’re three weeks on from installing the new Vizio M65 and its associated Tivo Mini. As described previously, the Tivo Mini needed Ethernet, so I used a Raspberry Pi 3 as a Wi-Fi bridge.
At the outset, this arrangement seemed to work. However, several times the Mini lost its network connection. In particular, when rebooted it would often fail to re-establish connection to the Roamio Pro that has the tuners and all the stored programming.
In that state, on the network but unable to find the main unit, the Mini has limited functionality. It can only access streaming media accounts like Netflix, Amazon Prime or YouTube. It does this directly, with no help from the Roamio Pro.
I suspect that the Mini, which is by no means a high-performance device, suffers network issues poorly. In fact, both Roamio Pro and Tivo Mini are old and likely prone to trouble resulting from network latency or instability.
