I have a TM3402a cable modem. I have my Google mesh WI-FI router plugged into one of the Ethernet ports and it works fine. I would also like to connect my Macintosh via Ethernet, but I am being told that the other Ethernet ports on that modem cannot be used that way. What would be the purpose of 4 Ethernet ports if they are not functional? Thanks
