I'm trying to get onto my wireless laptop, but it will only work with a dongle. To get on to it, it's asking for security code and I don't know what it is.
Can you please help with this.
Are you talking about your network key? If that's the case, none of us can tell you it. It was put in place with whoever set up your wireless router. If they did not change the router login password, you can connect your notebook to it and check what the key is, however.
