Hello. I have a Mac Studio with Bell Fibe router/modem. I am unable to set my ethernet to accept the 10gbe option. I am not a guru. I do know that the modem is putting out 3.3 gig but can only get 940ishMB. There is nothing except the cable from the modem to the ethernet port. I tried Cat 7 and Cat 8 with no luck. Anyone have any ideas?
What is the port on your router rated?
5GbE?
"I do know that the modem is putting out 3.3 gig"
How do you know this?
It's a real thing that not all interfaces negotiate the rate of the other interfaces to which they are connected.
There are a lot of low-cost "10GbE" switches that negotiate either at 1GbE, or 10GbE (they do not respond at-all to 2.5GbE or 5GbE).
Do you happen to have a 10GbE switch handy, for testing
This being said, I can safely say that my '23 M2 Studio's '10GbE' can definitely negotiate a 2.5GbE, as well as a 10GbE link . . . I have nothing with 5GbE, so I cannot speak for that.
