A wire stabilizer for 8-core twisted-pair network plug is disclosed to have a first wire channel and a second wire channel respectively arranged at left side and right sides thereof, and a third wire channel, a fourth wire channel and a fifth wire channel 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 third and fifth wire channels are adapted for accommodating the twisted pair of the third and sixth core wires selectively. When connecting the network plug to the network cable, the worker needs not to memorize the installation position of the twisted pair of the third and sixth core wires, facilitating quick installation. Further, as the third and sixth core wires are kept apart, the invention enhances network characteristics.
