If you don't secure your wireless network, everything on your network, including personal information, could be accessed by strangers.
Password-protect your wireless connection. Turn on WEP (wired equivalency privacy) or WPA (Wi-Fi protected access) on all of your devices, including your router, your media center, and your Microsoft Xbox entertainment system. For more information, see Set up a security key for a wireless network.
Place the wireless access point away from windows and near the center of your house to decrease the signal strength outside of the intended coverage area.
Keep all software current (including your web browser) with automatic updating. Make sure that your firewall is turned on and use antivirus and antispyware software from a source that you trust, such as Microsoft Security Essentials or Windows Defender (built into Windows 8).
