since 2.5G switches are rare, but 10G RJ45 switches abound...

Please try Sabrent TH-3WEA USB3 -to- 10G RJ45 as an adapter (not for the 10G speed, but merely for the 2.5 to maybe 3.5G speed interface to a RJ45 10G switch).

It should be an interesting experiment, especially if you use a USB3.0 Type A to Type C adapter (as most older equipment has USB3.x but are Type A).

Thanks, I enjoy your youtube videos.

10G switches typically support only 1G and 10G speeds. There are some that can do 1/2.5/5/10G, but they are rare and expensive.

Rare, yes, but that's quickly changing. Expensive? Maybe compared to 10G ebay specials, but for new 10G Base-T gear, not really.

For $270 you can get a switch with 4x1g, 2x1/2.5g, 2x1/2.5/5g, 1x1/2.5/5/10g and 1x 1/10G SFP+: NETGEAR 8-Port Multi-Gigabit Smart Managed Pro Switch with 10G Copper/Fiber Uplinks (MS510TX) - Newegg.com

For $460 you can get one with 8x1/2.5/5/10G and 2x1/10G SFP+: ZyXEL XS1930-10 8-port Multi-Gigabit Smart Managed Switch with 2 SFP+ Uplink - Newegg.com

I expect over the next few years we'll see a whole lot more selection at even better prices. It doesn't really cost the manufacturer much more to support 2.5 and 5G if you're putting in a 10G Base-T port anyway, so I expect most new 10G switches going forward will support those speeds.

2.5G and 5G are taking off in a big way right now, because unlike 10G, they run just fine on Cat5e, and there's A LOT of Cat5e installed in buildings throughout the world that isn't going to be replaced anytime soon. And unlike 1G, they have enough bandwidth for WiFi 6 backhaul.
