A wired network offers speed and security advantages over a wireless network, and is more resistant to electromagnetic interference. If you want to extend your network to two or more buildings on your property, wired is the right choice, although the initial installation is labor-intensive.
Digging my own Ethernet in my backyard to a detached garage
Cat 6, Cat 5 or Cat 5e Ethernet cables can be installed outdoors to network computers between homes or other buildings using a local area network (LAN). Although regular Ethernet cables can be used, it is better to use the more expensive weatherproof Cat 6 cables.
Due to their thin plastic casing, regular Ethernet cabling quickly deteriorates when exposed to the elements. For best results, when running regular Cat 6 Ethernet cabling outdoors, place the cables in a conduit, such as PVC or other plastic conduit that is installed in a watertight manner. Then bury the conduit underground to a depth of about 6 to 8 inches and at least that far away from power lines or other sources of electrical interference.
Even with a conduit, it is better to use a weatherproof Ethernet cable that is designed for outdoor use. Conduits can fail in extreme weather, such as heavy rain or freezing temperatures.
