I have a friend who is signing up to get his internet connection up and running online. He is using a wireless service. He asked me if I know anything about setting up wireless network. I suggested he uses the suggestions that are freely available online to ensure his connection is secure and encrypted. After all, the last thing you need is someone piggybacking off your connection and using up all your download allocation. If you have a limited download connection, this can get used up quite quickly.
