The answer is “No different”.
Now, the Ethernet goes through the Eero base station to get to the ISP modem, but I checked and it isn’t slowing things down. On a Sunday evening (probably lots of people in the neighborhood online) we were getting 310 down, 15 up.
What’s actually interesting is the Ethernet is 25-year-old Cat5, I was wondering if that’d be able to keep up with the reasonably-modern Eero mesh.
@wordshaper @timbray I have a dodgy home wired (incorrectly paired) cat5 between up and downstairs - originally used for 10baseT.
Unchanged - I now squeeze 150Mbps speeds on Gigabit symbol rate. I could fix it but it’s my own little private joke to myself that makes me laugh.
