    I'm planning on joining two ethernet cables together with a coupler in order to make one long cable. The problem is, one cable has 568-B wiring and the other has 568-A wiring. Will this kind of connection work, and if so, will it affect the integrity of my network? I doubt I will need any crossover cable; the two cables will go directly from the router to a single computer. I just want to extend the existing cable's length using a coupler and all I have available is a cable with different wiring.

    Note that the only difference between the two wiring standards is the color of the pairs that are used, the twisted pairs are still on the same pins. You should see no difference and no crossover cable required. The Ethernet traffic doesn't know what color the wires are. :)

    You don't think using joining two cables with different wiring systems with a straight-through coupler will convert the one long cable into crossover one?

    This is what I'm planning to do:

    Nope, it'll still be a regular cable.

    The end connected to the modem is 568b and the end connected to the computer is 568a. Wouldn't that in essence be a crossover cable? That's what I'm trying to avoid.

    568A is a straight through wiring standard and 568 B is a straightthrough wiring standard. The only difference is different pair combinations as far as coloring. Crossover should be labled crossover or x-over somewhere on the cable if it is one and THEN you would have an issue. As stated 2 other times prior - your good providing all thei nformation supplied is correct. Also it won't hurt anything to hook it all up and power it on and see for yourself.

    Okay, thanks for the advice. When I go out to buy the coupler I tell you how it goes.

    Just got the coupler today. Works great, no perceptible lag.
