How do I unplug a cable on the wireless network connection?
If you mean to Unplug an existing cable in order to plug in a new cable to the router, then you should be aware that the ethernet plugs are similar to your phone plug with locking catch. Examine the plug you wish to unplug and locate the little catch at one side of the plug, and with your thumb nail pull the catch toward the side of the plug which should then be able to pull out normally. Remember also that these plugs can only fit in the socket with the catch the right way round. See links below for connecting back up if you need it.
