Can I add a second ethernet cable to my router, in my home, 200 ft. to my garage? I have wireless internet but my garage is too far away to pick up on it. I really don't want to pay AT&T to set up another connection at my garage. I have two 100 ft. ethernet cables. Can I connect them together? I have two laptops and three PC's in all. I want to put one of the PC's and a laptop at the garage.

While 200ft is within the limit of 330ft/100m, it's long enough that you're going to need very good cable with minimal joins. I would expect dropped packets over a join on that distance, unless you had an active switch in the middle.

A directional WiFi link at each end is probably a better option.

You best bet is to buy a $1 rj45 coupler and hook the cables together and then plug it into your switch and a pc all in the same room before you go to the trouble of running it. It should have no problems but the official standard requires you use a TDR meter to certify cable installed with a splice like this in the middle. Since that is not a valid option for a home user you next best thing is to test it with a pc.

I am going to suspect it will be fine since we have cables going though multiple patch panels and having them tested and certified did not change the fact that we had multiple of these splice connection in the path it just means we are really sure it will work.

You will of course need a switch at the far end to connect 2 devices to the cable.

Thank you! What is an active switch?

If you do not have a switch already laying around it will be a much better option to just buy a 200ft cable that buy a switch and deal with if you can find power to plug it in or not at the 100ft point.

I would still try what you have first with a simple coupler. Just because it does not meet the standard for a cable does not mean it will work. The concern is the coupler in the middle will introduce more resistance on the wires. The coupler itself is not the problem these are clearly allowed to connect from the patch panel to a end machine it is just that there is a limit in the standard on cable length on this.

Again all this likely does not matter. Test it and see if it works, most cable far exceed the minimum requirements.

I would pay much more attention on the cable itself. How do you plan to lay this cable? Underground? Above ground? On Poles? How about lighting protection? What about local building codes?

Wcichever way you go, you will need new cable. Look for cable designed for your chosen method of laying it. Terminate the cable at both ends on RJ45 receptacles. On your garage, if you want to connect more than one PC, you will need cheap 5-port switch (and this assumes that you have power in the garage).
