My broadband connection randomly and frequently drops, particularly when composing Emails on Sky mail and messages on sites such as Facebook and other forums. Running the troubleshooter always fixes the problem and the messages I get are 1) A network cable is not plugged in and 2) the computer was manually disconnected from network profile. My router is a Sky Sagem, using Sky Fibre Broadband. It is connected to my PC wirelessly and so I do not understand why it complains that a network cable is not plugged in. Any suggestions would be very welcome as this problem is annoying me!
