Anyway, you are asking for trouble by not using antivirus software, unless you are using Mac. Even then, Mac isn't immuned to viruses. As I have said, there are some viruses which are capable of disconnecting one from the Internet, with or without the antivirus installed.
The ethernet cable is hardly the source for frequent disconnections, unless it isn't plug in properly.
