I have a Netgear router supplied by my ISP. I have a wired connection to the computer and have no problems. I have no need for a network as I only have the one PC. Although I am not using the wireless connection I wonder if there is the possibility of external unauthorised access. The router installed itself and set up the ADSL internet connection. Control Panel (Windows 7) shows a Network connection to the Internet and a Home Network. Apart from changing the default password I have taken no network security precautions. Am I at risk? I have a reliable connection and don't want to disturb anything unnecessarily.
