I get good streaming for a while, but after a few minutes live TV gets "jumpy" (pauses more and more), and playing shows prerecorded on the Roamio eventually fails with the "network too slow" error from my Mini.
1. Is there anything I can do to "tune" my network to improve it? Apple's products, of course, are well-known for not letting you get down to the nitty gritty of configuration.
2. Why is it that I never had this problem when I had two Premieres? I could play prerecorded shows from either box to the other one over the exact same connection without a problem.
Not sure why you are having issues with the Roamio-Mini combo and not the Premiers. Below are a couple of things you can try which do not necessarily fall under the category of tuning your network but may solve your issue. The options are presented in order from the least to the most costly so I would therefore try them in the order that they are listed below. The 4th option, however, will be your best bet and result in the most reliable connection/streaming experience.
1) If you haven't done so already, try rebooting the Extreme, Express, Roamio, and Mini
2) If you can, try swapping the locations of the Roamio and Mini. The point of this is so that the Roamio will be connected to the Extreme and the Mini to the Express. With your current connection, you are uploading/sending the Roamio's stream through the Express and it's wireless-N connection, which is the bottleneck. It shouldn't make a difference, but it may be more efficient for the network to instead have the Roamio located at the Extreme's location. That way, the more powerful Extreme will be primarily sending Roamio data downstream to the less powerful Express (instead of the reverse like you currently have it setup). The bottleneck of the wireless-N connection will still exist but this may be a more efficient way to optimize the connection. In your previous setup, if you were primarily streaming video from the Premiere located at the Extreme to the Premiere located at the Express and not having issues, that may also help explain why you weren't having issues then but are having them now.
3) Does your version of the Extreme support wireless AC? If yes, try using a wireless bridge that also supports the faster wireless AC standard to connect the Roamio to your network (I believe the current version of the Express only supports the slower wireless-N/G/B/A standards). Here is one example ($35):
4) Assuming you have coax connections near/available at both the Roamio and the Mini (you were previously using two connected Premieres, so yes, right?), you can try using a pair of Moca adapters to create a wired connection between the two ($90): https://www.tivo.com/shop/detail/moca-2
Under this scenario, you would use one Moca adapter to create the Moca network by connecting to both a coax wall outlet and your Extreme (Mini remains connected to the Extreme over ethernet). The other Moca adapter would be connected to a coax wall outlet near the Roamio and then ethernet from that to the Roamio.
The ideal scenario, however, would be to swap the locations of the Roamio and Mini so that you would only need one Moca adapter ($50): https://www.tivo.com/shop/detail/moca
The single adapter would create the Moca network at the Extreme's location (connect wall coax to Moca adapter's coax input and ethernet from adapter to Extreme). Roamio connects via ethernet to the Extreme and also to the coax output on the Moca adapter. The Mini would then just connect directly to a wall coax outlet in the other location since the Mini has a builtin Moca adapter.
5) If your Extreme supports wireless AC, you can also try replacing the Express with the following ($90):
