I currently share my Internet connection between 2 PCs using 2 NICs & a 30m piece of Cat 5e cross-over that is wired through the house when it was built, I am about to change my router to a wireless one and need the cable to be a straight is it possible to convert this cable without cutting the ends off ? A friend told me connect a second cross-over cable to the first, using a straight-thru connector to make it a straight would this work ?
