Would it be a fire hazard to drill a hole in the wall and run an ethernet cable up into the atic and then down into my room??
Make sure though that when you drill a hole into the wall you do not hit any cables/pipes/etc running in there. ;)
There are tools that detect cables/pipes in the wall. Or an up-to-date blueprint can work as well.
That is a Very Odd Question
Eh, to someone who hasn't dealt with running cable before I can see how this is a concern.
Instead of just drilling a hole and poking a cable through it, I'd install an actual ethernet jack. But yes, like Cmdr__Tim said, that is common practice and not at all a fire hazard.
This guy gives the gist of it.
I personally see the value in running more than one cable at a time, in which case, you should drill larger holes. There's also something to be said about patch panels and switches, but he didn't mention either of those in this video. Oh, and don't cut the wall with a box cutter. That's just silly. They have drywall knives for like, $10 or less.
Things he didn't talk about that he probably should:
Anyway, there are multiple ways to do this, but I believe there is a right way.
As said before...thats how you would run cable, it is low voltage so chances of fire are slim. But that being said, by law in the US and by code you need to use Plenum rated wire. If you are going Cat5e the price shouldn't be that different....as stated get yourself a tester and the tools needed.
