You don't. This (wireless broadband) is not the same as a wireless LAN router (wireless LAN access to a broadband link) which usually should be secured (e.g. using WEP or WPA and MAC address filtering etc.). If you mean securing your PC generally then that's a separate matter. Check the "clean PC" thread pinned at the top of this forum for tips on firewalls, viruse/malware checkers etc.The instructions i got was just a leaflet telling you to plug the earthnet cable into the back of the computer and then turn it on. i have internet access but there was no mention of how to secure the connection.
