I want to run about 100 meters of Ethernet cable out my attic and down a drainpipe. The cable will be exposed to the elements, and attached to a gigabit switch (indoors) at both ends.
What kind of cable do I need? Can I get a basic Cat5E bulk cable, or does the length and exposure mean I should opt for Cat6? Or is there some other outdoor-rated specification of wiring that I should be using?
