SSID securityĪn SSID is necessary for a secure network, but on its own, it doesn’t do much to make a network more secure. Recommended Reading: Interested in learning more about Networking?

As part of the association process, a wireless network interface card ( NIC) must have the same SSID as the access point or it will not be permitted to join the basic service set (BSS) a component of the IEEE 802.11 WLAN architecture. The SSID differentiates one WLAN from another, so all access points and all devices attempting to connect to a specific WLAN must use the same SSID to enable effective roaming. This helps to ensure that data is being transmitted to and from the correct network. The IEEE 802.11 WLAN architecture standards specify that the SSID be attached to the header of packets sent over a wireless local-area network ( WLAN). Image Description: Change your network name (SSID) and password in the wireless modem settings. Alternatively, you can contact your ISP technical support team to walk you through the steps or have the network name and password changed for you. Once logged in, you can then change the network name (SSID) and password for your network. The modem manufacturer will provide a common IP address that you enter in the address bar of a Web browser to access settings, using a generic username and password. The SSID can be changed in the software configuration pages for your wireless modem. This makes it more difficult to hack into the network, and it also makes it less likely that two networks with the same SSID will be within range of each other. However, security experts recommend changing the default name and password. Many router manufacturers set up their devices to use a generic name by default (often the make and model of the router). They are also case-sensitive “HOME” is a different network than “home.” SSIDs can be up to 32 alphanumeric characters long. How to change the default Service Set Identifier name and password Mobile devices will look for all networks in range when you attempt to connect to local Wi-Fi. Image Description: SSID is the name for a Wi-Fi network. Note that some public networks, typically managed by a business, may require you to first read and agree to an online terms of service ( ToS) before allowing you to connect.
You will select the name of the local network you want to connect to and then enter the password (if necessary) to connect. This is the names of all the networks that are within range of your mobile device. For example, if you take your laptop to a coffee shop and attempt to connect to the local Wi-Fi network, your screen will display a list of SSIDs.
People typically encounter a Service Set Identifier (SSID) most often when they are using a mobile device to connect to a wireless network.
