I'm trying to run an Ethernet cable through my wall, up into my ceiling, and into my unfinished laundry room. I want to follow the path of a coaxial cable that's already there, but it has a small metal box around it. Should I cut a new hole to insert the Ethernet cable, or would it be better to unscrew the box instead?

It could depend on what that box is doing. I'd suggest unscrewing it first to see how it's set up. A quick tip: if the existing cable is loose, try tying the new Ethernet cable to it. This way, as you pull out the old one, you'll be able to guide the new cable in without too much trouble!
As a cable technician, I can tell you that just running a new path often ends up being the simplest way to go. Residential installations tend to have their challenges without the right tools. Do you have push rods or a long flex bit? And be cautious of any horizontal studs that might be in the way!
Yeah, if you can manage it, that’s a solid plan for making your life a bit easier!
Do you even use that coax cable, or is it just taking up space? If it's still connected, you could use it as a pull cord for your new Ethernet cable and keep it for future use too!
Honestly, it doesn't make a huge difference what you choose! If the box has knockouts, just knock one out or drill a hole in it. You could also unscrew it or just create a new entry point in the drywall nearby to get your cable through. Whatever works best for you!

I’ve had success using the old cable to pull in a new line. Last time, I even brought along a steel cable for potential future needs. Just a thought!
