SSID is the name of the wireless network. The SSID differentiates one WLAN from another and have the predefined set by router names Manufacturing as “Linksys” or “D-Link”. Your wireless router will broadcast the SSID details in the air for other devices lock on. So it will expose the name of your router to other wireless users.So users can access your wireless network by entering the default password and the user name of this router if you do ‘have not changed your username and default password before.
To avoid this, you can disable the SSID broadcast your information from your router configuration page. So not your most neighbors know the details of your network.
Yet it is possible to find the details of your SSID using some free WiFi analysis tools as inSSIDer (Windows) and Kismet(Mac, Linux).
So you should change your wireless network name (SSID) in the settings page to prevent others to obtain basic information of your router.

WPA2 is then introduced in 2004, it is the best secure encryption mechanism prevents espionage, and it supports all new WiFi devices.
To encrypt your wireless network, Access security settings in the router settings and choose WPA2 or WPA or WEP encryption method. Then enter the most complicated password (alphanumeric combination of words) to access the network.
Free third-party tools like AirSnort or Aircrack-ng can quickly recover WEP encryption key using brute force and dictionary attacks.
5. Reduce the range of WiFi signals
Currently, the 802.11 has three distinct frequency bands such as 2.4 GHz, 3.6 GHz and 4.9 groups / 5.0 GHz. Each frequency range has wireless multi channel that has different signal strengths. The range has 24.GHz (802.11b / g / n) wireless channels. You can choose 802.11n or 802.11b 802.11g instead of reducing the signal power range. Otherwise, you can put the router in the closed room or something like that to remove the signal strength.
These steps will help to protect your wireless network, data and your privacy against hackers and other intruders. Now your WiFi connection is highly secure and it will take ages to hack your wireless connection if you have followed the steps above.
