Can someone guide me on how to secure my internet connection. I have a d-link router (one antenna), a 3Com Home Connect modem and I'm running XP with service pack two. I have two computers and one laptop network. I've been using the network since December with no problems but last night I noticed that someone else was on the network. I would like to secure the connection so that no one else can have access to my connection.
Thanks for your help.
