Newbie here. Just got a Roamio Plus and a Mini and I'm having networking issues between them. I've seen lots of posts of various issues with this kind of setup, none of them frankly with clear root cause or resolution and none quite addressing the issues I'm seeing so starting my own thread.
The Roamio and mini are connected via gigabit ethernet. When I first connected them the mini quickly found the Roamio but when I tried to stream video (either live or recorded) it would stutter, dropout audio and eventually lose the connection. Usually a V87 error but sometimes other errors.
I eventually, through trial and error discovered the following. The mini was connected to the network through a Netgear hub. Among the other devices attached to the hub was an Airport/Time Capsule. Unplugging the Airport allows the mini to work flawlessly.
I've repeated this a few times. The most recent time I had the Airport unplugged and the mini working fine. When I plugged in the Airport after a minute or two I began to get audio dropouts, video stuttering and freezing and within a few more minutes a dropped connection completely.
I'm not sure about next steps, so I'm looking for ideas. One possibility is upgrading the hub to a switch. But before I go spend money on new hardware I'd like to have a better understanding of what's going on. Just throwing money at the problem doesn't feel like the right answer in this case. It's rather disappointing that Tivo is so sensitive to these network conditions.
