Nope. Been there, done that. At least for the Leviton connectors, the Cat5E connectors do not work well with Cat6 cable. The tolerances are close enough that the greater thickness of the wire will break the connector. I accidently ordered the wrong connectors on a Cat6 job, and couldn't figure out why I was so fumble-fingered all of a sudden. I was breaking connectors left and right until I figured out the goof.Does 23awg solid Cat6 be terminated on a cat5e leviton keystone?
