First You need to know that wireless access points and routers establish a wireless network by using Service Set Identifier.
Typical default SSIDs are simple names like below
“wireless”
“netgear”
“linksys”
“default”
The SSID can be accessed from within the router’s web-based or windows-based configuration utilities. It can be changed at any time, but wireless clients must then recognize the new SSID in order to reconnect to that router and network network.
To improve the security of your home wireless network, you need to change the router’s SSID to a different name than the default. Here are some recommended do’s and dont’s based on recommended network security practices:
– Don’t embed your name, address, birth date or other personal information as part of the SSID
– Don’t Use any of your windows or internet website passwords
– Don’t tempt would-be intruders by using tantalizing network names like “S3xy” or “Secret”
– Do pick an SSID that contains both letters and numbers
– Do choose a name as long as nearly as the maximum length allowed
– Do consider changing your SSID periodically at least once in a month
In order for a wireless device to connect to a wireless network it is must to know the network name or SSID (Service set identifier), of the wireless network in question. If you plug your wireless router or access point in and leave the default SSID, it won’t take long for an attacker to determine what the SSID is.
To change the default SSID to something unique, you need to access your wireless router administration console. Refer to the owner’s manual for your particular wireless router or access point to determine how to access the configuration and administration screen where you can change the default SSID.
For most wireless routers, this is done via a Web Browser. Simply type 192.168.1.1 in your web browser address bar (note that the default IP address may vary by vendor, or if you have changed the default IP address, substitute whatever the IP address for your wireless router is).
To gain access to the actual administration console, you will need to enter he administrative username and password for your wireless router. Some vendors allows you to change both the username and password, while some only allow you to change the password. You definitely should not be using the default username and password since any attacker can find out what the information is from the vendor.
Once you are in the administration console for your wireless router, navigate to the wireless settings so you can be able to view and modify the SSID. The actual steps may vary by vendor, so refer to your wireless router documentation for details steps. The example im giving here is based on a linksys
1 – Click on Wireless on the top menu bar
2 – Click on basic wireless settings on the sub-menu
3 – Here You can see the Network name or SSID
4 – Enter a new SSID into the Network Name (SSID) field.
When changing your SSID make sure you change it to something unique, if you use information such as your name or address an attacker may be able to successfully guess what your SSID is.
