An unsecured wireless network can be used by outsiders without authorization, and is more susceptible to outside attack. To make your wireless network more difficult for outsiders to access without permission, you should enable your computer's security wireless settings.
There are three different levels of wireless security you can use to protect your wireless network. The least secure level is 64-bit WEP encryption. If your router and PCs support the stronger 128-bit WEP or WPA encryption, you should use one of these methods, instead.
There are three different levels of wireless security you can use to protect your wireless network. While 128-bit WEP encryption is stronger than 64-bit WEP, it is not as secure as WPA encryption. If your wireless router and PCs support WPA encryption, you should switch to that method for the strongest protection.
Every wireless network has an SSID, which serves as the network’s name and identifier. The SSID is assigned by the router. Many router companies use their names as the SSID (for example, “Netgear” or “Linksys”). Common SSIDs such as these make it easy for intruders to identify and access your wireless network.
