Before I can hang the drywall, I need to figure out where these cables go and either re-route them, or cut them off and abandon them. One is CAT5 and the other RG-6 coax. I found that the CAT5 went to the in-law suite downstairs so I chopped the head off down there and pulled it out. No need for hard-wired network when I have good WiFi. I haven't found where the coax goes so it'll stay here until I can find it or I'll just stuff it back into the floor and fish it out from below if I find it's necessary.
