I have a phone jack in a room at my house, where it has many colored cables, which I am assuming can be used to change the jack to allow Ethernet to be accessed through the wall output. Is there anything specific I need to get to make sure this could happen? As well as a way to find out where all the wiring goes to? Thanks!

phone wires have two twisted pairs. you can probably get a 100Base-T going, assuming the other end is near your router. If you are really lucky they used cat5 (4 twisted pair) and wired it to a phone jack. If it's coming in from the ISP then it's not going to help you out. Good luck finding the other end.

If the wire wasn't secured through the wall you might be able to pull some cat5e through using the phone line.

Almost certainly not.
Even though they look mostly the same, they're not.

Is it an actual RJ-45 jack, or an RJ-11 (phone size)?
What is connected to the other end of those wires?

MERGED QUESTION
Question from benjaminfarias313 : "Phone jack to Ethernet? Cat 5 possibly"

I have a phone jack in a room and the colored cables that the phone cable has are orange orange/white brown brown/white green green/white blue/white. Is there anyway I can change it for Ethernet?

P.S. all the other phone jacks have black yellow red and green colored cables.

This.

However, most 4 wire phone cables have horrible shielding. It *may* work if it's quality cable, not a long run, and you crimp a network connector on both ends (same colored cables in pins 1, 2, 3, and 6 looking from the contact side). It also may not work. Better option is to run a network cable.
Also, I'm assuming that you know a little about networking/computers and aren't expecting an actual phone line (hooked up to dial tone) to magically turn into a network cable just by crimping a jack on one end. (sorry, can't be too careful with assumptions ;))

You can do it easily. You need an 8 pin Ethernet port /jacks on both ends of the wire you only need 2 pairs of wire use green/white green and orange/white orange of the ports wire color doesn't really matter as long as you put both ends on the same color of both ports
