[ale] Looks like time for a new wireless router

[Jim Kinney]

I did 10g copper to join a pair of netgear GS110MX switches between
downstairs and upstairs. Not a long run of cat6 - maybe 80 feet? With the
fiber line in at 5Gbps it seemed a waste to throttle the backbone to 1Gbps.
So a trio of 10G nics on the firewall box , 10G nic dmz, then another 10 to
the downstairs switch, that upstairs switch feeds office and wifi and the
roku tv is happy and no bad video calls even if the tv is wasting power and
brain cells.
