> Yes, that's the thing I like about the Arlo system I have now: it has its own wifi network so, even if it's using spectrum, it's probably not affecting my LAN throughput.
Wifi6 is changing a lot of this, but generally speaking Wifi performance is not optimized for media style traffic. Media traffic does best with low jitter (variance of latency) as this tends to keep buffer sizes low and avoids dropping frames. Wifi is not very good at low jitter, and though Wifi6 is a lot better than previous Wifi standards, it's still much harder to keep jitter low on Wifi than it is on a LAN. On top of that, as the sibling commenter says, even if you have a separate Wifi network, spectrum doesn't segment that neatly. Wireless traffic uses multiplexing methods (there are several and if you're interested, the methods are fascinating [1]) to roughly use the same spectrum. These multiplexing methods obviously need to do more work the more traffic there is on the spectrum.
If you can route your media traffic through LAN do it. Obviously as you say, running new cable is a lot of work so it's understandable why you use Wifi. But LAN is just so much better that if you have the time/money (doing it yourself/hiring someone) to do it, I highly recommend you do.
