I have a small home network with just one incoming line. I acquired some leftover Cat 6 cable from a job I worked on as an electrician. (I know I have to buy Cat 6 RJ45 connectors), but I figured I'd try to use a Cat 5 connector that I had from previous Cat 5 wiring on my network. The Cat 6 WILL fit into the Cat 5 connector. I only use the Blue and Blue/white wires, so its easy to get them in. They don't seem to connect with the wire after crimping. Even though you can see the sharp, piercing stabs bottoming out. I never could get them to work. Even though you can get the wire in, whats the difference between the Cat 6 and Cat 5 connector ?? The Stabs ?
