Slow Ethernet speeds

I have a MacBook Pro 2017 running is 10.14.6 and a new Mac Mini 3.2 i7 running is 10.14.6 and both of them work fine with wifi. But when I use an Ethernet cable connection it is slower than the wifi speeds. Super frustrating.


My Ethernet cables are CAT 6. I’ve tried 2 different cables.


Comcast came to my home and checked the connection only to say it must be my computers and to contact Apple. Any ideas?

I don't know if this will help you or not. But check the switches in your home. My house was wired directly for internet, and I had the same problem you did, my wifi was much faster than my wired connections.


The smart box had a 100 mbps switch, and that was causing the slow down. I replaced with a gigabit ethernet switch and that solved my problem.


If you are directly connecting to the Comcast router, they're probably lying to you. :) If you have a friend with faster ethernet, see if you can hook up there to check your machine.
