How can I add more ethernet ports to my router?

Episode 1493 (59:00)

Kevin from Vancouver, BC
NETGEAR 16-Port Gigabit Ethernet Unmanaged Switch

Kevin needs to have more than two ethernet ports on his router and his mesh router only has two. Leo says he can get an ethernet switch or hub that can expand the amount of ports. Leo has one with 24 ports! They're all easy to use, and the best part is they're all the same. NetGear makes a good one. But any one will do.
