Need to run a rj45 wire?

Question

need to get it upstairs and am running into something behind the wall need to get past that I am tring to connect one computer to the other don't know what to do go through electrical phone or the cable those are already outlets i dont know i dont want to have it hang outside of the house i want to do a neat job. I have little time to do this

Answer 1

Inside the wall is a "fire block" at around 4'

You might also be hitting the top plate, or the bottom plate of the wall on the second floor.

Chances are you have to cut open the wall (and patch) where the obstructions are unless you have a long, flexible drill bit.

BTW: the jack is called rj 45. The cable is probably cat 5.

Answer 2

Not sure about your budget but if you can't go wireless then you need to purchase a snake also called fish tape made to run cable\lines. You can find one at lowes or home depot.

it will run you about $25

Here is a link to amazon of one.

good luck,

Answer 3

You can find bulk supplies of the cable at many computer stores or most electrical or home centers. You want UTP (Unshielded Twisted Pair) Category 5 cable for basic 10/100 functionality. You need CAT 5e for gigabit (1000BaseT) operation and CAT 6 gives you a measure of future proofing. Bulk cable comes in many types, there are 2 basic categories, solid and braided cable. Braided cable tends to work better in "patch" applications for desktop use. It is more flexible and resiliant than solid cable and easier to work with, but really meant for shorter lengths. Solid cable is meant for longer runs in a fixed position. Plenum rated cable should/must be used whenever the cable travels through an air circulation space. For example, above a false celing or below a raised floor.

You're likely going to want braided type cable but it may be difficult or impossible to tell from the box.

The RJ45 end is a 8-position modular connector that looks like a large phone plug. There are a couple variations available. The primary variation you need to pay attention to is whether the connector is intended for braided or solid wire. For braided/stranded wires, the connector has contacts that actually pierce the wire. For solid wires, the connector has fingers which pierce the insulation and make contact with the wire by grasping it from both sides. The connector is the weak point in an ethernet cable, choosing the wrong one will often cause grief later. If you just walk into a computer store, it's nearly impossible to tell what type of connector it is. Strip off about 2 inches of the cable sheath.

Untwist the pairs - don't untwist them beyond what you have exposed, the more untwisted cable you have the worse the problems you can run into.

Align the colored wires according to the diagrams above.

Trim all the wires to the same length, about 1/2" to 3/4" left exposed from the sheath.

Insert the wires into the RJ45 end - make sure each wire is fully inserted to the front of the RJ45 end and in the correct order. The sheath of the cable should extend into the RJ45 end by about 1/2" and will be held in place by the crimp.

Crimp the RJ45 end with the crimper tool

Verify the wires ended up the right order and that the wires extend to the front of the RJ45 end and make good contact with the metal contacts in the RJ45 end.

Cut the cable to length - make sure it is more than long enough for your needs. Remember, an end to end connection should not extend more than 100m (~328ft). Try to keep cables short, the longer the cable becomes the more it may affect performance, usually noticable as a gradual decrease in speed and increase in latency.

Repeat the above steps for the second RJ45 end.

If a cable tester is available, use it to verify the proper connectivity of the cable.

That should be it, if your cable doesn't turn out, look closely at each end and see if you can find the problem. Usually a wire ended up in the wrong place or more commonly, one of the wires didn't extend to the front of the RJ45 connector and is making no, or poor contact. If you see a mistake or problem, cut the end off and start again.
