You should know for full proof wireless security

Firewall protects your network from unwanted traffic. It is designed to permit or deny network transmissions in accordance with preset rules. It protects the networks from unauthorized access, so it must be ensured that the firewall option is not disabled. If the firewall option is not provided in your router you can turn it on from the control menu of your operating system.

DHCP or Dynamic Host Configuration Protocol is a protocol which assigns a unique IP address to the device connected to a network. Turning it off is a necessity to ensure 100% protection to your network. As it assigns dynamic IP address to a device automatically, turning it off would obstruct this process so you must manually assign a static IP address to all the devices which you wish to connect to your network.

Changing the Default Router Password is a prime necessity as the default passwords are common and well known to hackers. Choosing a strong password would ensure full proof security to your wireless network.

Encryption ensures protection to the password and makes it difficult for the hackers to crack. WEP, WPA, WPA-2 are the most common types of encryption. WEP, WPA encryption provides reasonable protection but WPA-2 is considered most secure. So you should prefer WPA-2 encryption to ensure maximum security to your wireless network.

Setting a strong password for your wireless network is vital. Setting a secure encryption level but not setting a strong password would not do any good for the protection of your wireless network. A secure password should contain at least 14 characters including lower and upper case letters, numerals and special digits. More complicated passwords are more difficult to crack.

SSID refers to the public name of your wireless network. To ensure the security of your wireless network, you should not disclose SSID to everyone as it may encourage individuals to try to gain access to your network.

Using more routers (for better signal strength) can pose threats to the security of your wireless network. If more than one router is necessary for your wireless network ensure that they are properly encrypted and password protected. Using fewer routers will ensure protection to your wireless network as there will be lesser security concerns.

Updating your computer with latest antivirus softwares plays a vital role in keeping your wireless network protected. An unprotected computer is prone to attacks of different types of programs, which can damage your computer and your wireless network.
