UniFi seem to have dabbled with 2.5 GBE briefly and then jumped to 10. I’m guessing that 10 will be the way to go.

You’re looking at cat 6A patch leads rather than 7. 7 requires different but RJ45 compatible connectors, I believe. Yes, I’m still trying to understand what the difference is.

I have a 2.5G router, the CG Max. A 1 G switch (waiting for a reasonably priced 10 G) and a 10 G WAP. It’s a bit of a mess!
