Here I have an ONT -- which acts as a special bridge -- which
connects via 10GBaseT to the 10G Eero router, which has 10G ports
and wifi.  10G to my 10G switch, which handles my 10G workstation
and 10G Synology NAS.

I need to run a Cat-7 wire straight down to Mrs. vallor's office
downstairs so she'll be wired, but currently, the wifi signal
is strong -- and she hasn't complained.

I tried setting up Link Aggregation with this Netgear switch (my
workstation has 2 - 10GBase-T ports, as does the NAS), but the
switch only handles Static LAG, and it's a bit flakey.  I bought
a switch to replace it that supports LACP, but haven't gotten
the round tuit to move over to it yet.

Oh, and the connection to the ONT is 10G XPON.  We believe
in getting customers to go as fast as possible -- this nonsense
by our competitors to hold down connection speeds so they can
soak the customer for upgrades stinks to high heaven.

Finally, the Eero router does IPv4 NAT, and also acts as
a firewall for IPv6.  Native IPv6 is a lovely thing.
