A wire stabilizer for 8-core twisted-pair network plug having a first wire channel and a second wire channel respectively arranged at left side and right sides thereof, and two third wire channels, a fourth wire channel and two fifth wire channels arranged at different elevations between the first wire channel and the second wire channel. The first wire channel and the second wire channel are adapted for accommodating the twisted pair of the first and second core wires and the twisted pair of the seventh and eighth core wires respectively. The fourth wire channel is adapted for accommodating the twisted pair of the fourth and fifth core wires. The two third wire channels and the two fifth wire channels are adapted for accommodating the pair of the third and sixth core wires selectively. The third and sixth core wires are kept apart, the invention enhances network characteristics.
