So im on a kind of DIY kick, and i want to hardwire the Roku in the living room so i can watch my WWE Network and Netflix with the max speed and whatnot. My question/problem is this: The wire will have to be ran about 10 feet outside the house, under a covered carport, then into the attic. Is Ethernet cables able to withstand this alone, or do i need to cover them with pipes or something. Also, are they rated for the extreme heat of a Louisiana summertime attic? Anybody have a little expertise to share? Also, should i get the latest/greatest speed cable?
