TiVo mini complains about connection speed
Last year, I replaced a complicated home networking setup that connects a TiVo mini remote unit with the main TiVo unit, with WiFi 5, a MoCa bridge and power line adapters, with a WiFi 7 mesh setup. Cable modem is attached to the main BE-25 on the second floor in the front/northeast corner of the house, called "Office", while the satellite BE-25s are in the kitchen (ground floor, southwest corner, two arcs of signal strength) and in the bedroom (second floor, northwest, three arcs). The bedroom BE-25 is connected to the TiVo mini by a 12" Ethernet cable; they're right next to each other. 4 devices are connected to the kitchen, 13 to the office (5 of them wired), and 9 to the Bedroom, including the main TiVo (wireless; ground floor north-side middle) ) and TiVo Mini (wired). My lovely wife likes to watch TiVo in the bedroom while she falls asleep, and gets annoyed when TiVo mini complains that the network connection is too slow. The Deco app shows "Everything looks good." I tried setting TiVo, TiVo Mini, and my work laptop to high priority, but my wife still sees the errors.
is there anything else I can look at or change that would enable the TiVo mini to stream 4K Video from the main TiVo any better? Speedtests show ~500 Mbit/sec download speed, and the Deco app always shows traffic in low-to-medium kilobits/second, so I don't see any signs of network saturation.
