My concern wouldn t be heat related.
Cat6 in attic.
I plan on replacing the existing coax faceplates with keystone faceplates with coax cat6 keystone jacks.
A zip tie loop stapled to the joist could be a good support solution.
A wired cat 6 network is more reliable and secure than a wireless network or cat 5 cable network for your internet connections.
Remember that the main thing which defines this cable as cat6 rated over cat5 is the center insulation piece that.
The cat 6 cable runs will follow the existing runs for cable tv coax in each room.
In fact attach to your joists.
Cat6 cable in attic in the attic i noticed i have some cat 6 cable wound up.
14 for 12.
You ll be fine running cat6 over the insulation.
Single gang retrofit boxes the kind that clamp to the drywall open back.
This is important when running the cable up the side of a house or across a roof.
If you aren t burying the cable choose a waterproof cat 6 cable that has a uv protective jacket to prevent damage from sunlight exposure.
1000 spool cat5e or cat6 cat6 recommended more or less based on your need.
The end i can get to is cut for me to work with if i wanted and i am not sure where the other end goes to.
Exterior grade ethernet cables are waterproof and can be buried in the ground without a conduit.
Rj45 jacks and plates get what you need maybe an extra or two.
