Whenever you use your Wi-Fi connection, you want to ensure that your communications and files are private and protected. If your transmissions aren’t secure, others may be able to intercept your e-mails, examine your files and records.
Your wireless internet connection can be used by your neighbors and anyone within range to use as their own, free, connection. If they are streaming movies, uploading/downloading large files, this could impact the speed of your internet connection.
In a home wireless network, you can use some simple procedures to protect your Wi-Fi connection. These include enabling Wi-Fi Protected Access, changing your password or network name (SSID) and closing your network.
