A mounting plate assembly for securing a plug of a network cable to a jack of an electronic device. The assembly includes a mounting plate having an attachment mechanism that is configured for releasable locking engagement with the electronic device. Further, the mounting plate is adapted to be mounted to a mounting structure. The mounting plate includes inner passageway that is adapted to receive insertion of at least a portion of the plug. Additionally, the inner passageway is adapted to depress a locking clip of the inserted plug to a position that prevents the locking clip from lockingly engaging a protrusion in an aperture of the jack. Further, the retention member may include at least one arm that is configured to retain the plug in a relatively static position relative to the mounting plate when the plug is being received in, and removed from, the aperture of the jack.
