7. Router Pile
“Where old Linksys routers come
from around the world to die.”
They don’t use Linksys routers
anymore because they have a
single radio and can’t do duplex
communication, which slows
traffic for a large network.

Weatherproof, easy to maintain when up a pole, single ethernet cable that also carries power
