Wi-Fi or wireless networks are great for the home and small business users, allowing to use of multiple internet-capable devices on one shared connection.

In traditional wired networks, it is extremely difficult for someone to steal your bandwidth but the big problem with wireless signals is that others can access the Internet using your broadband connection even while they are in a neighboring building or sitting in a car that’s parked outside your apartment.

Wireless networks can be subject to vulnerability, malicious eavesdropping, hacking, and freeloaders. The security protocol used to protect the vast majority of wifi connections has been broken, potentially, if you don’t use proper protection when you set up a network.

Piggybacking can lead to increased monthly Internet bills and a decrease in Internet access speed. More serious loss is from Hackers

Hackers can easily intercept wireless network traffic over open-air connections and extract information like passwords and credit card numbers, bank accounts, etc.

What is Wifi Security

Wi-Fi is one entry-point hacker can use to get into your network without setting foot inside your building because wireless is much more open to eavesdroppers than wired networks, which means you have to be more diligent about security. More about Wi-Fi

Wi-Fi network security keeps you and your information private, secure, and out of the hands of criminals during an online session. Security should be such as you are not intercepted for theft irrespective of wherever you are located, whatever type of hardware, using a public Wi-Fi connection or not,  No one should be able to intercept or steal any information sent or received during online sessions.

Wireless network security is the process of designing, implementing and ensuring security on a wireless computer network. The core area is the prevention of unauthorized access or damage to computers or data using wireless networks.

Wi-Fi is one entry-point which hacker can use to get into the network. The wireless networks don’t have built-in security mechanisms. Following three steps will ensure secured wifi network

Create a unique password for router

Change the default password of the router to something more secure from the Administration settings. This will prevent others from accessing the router.

Change Wifi Network’s SSID name

The SSID (or Wireless Network Name) of your Wireless Router is usually pre-defined as “default” or is set as the brand name of the router (e.g., Linksys). Although this will not make your network inherently* more secure, changing the SSID name of your network is a good idea. Never keep the name of your wifi as your house number or surname. The name should not be able to identify you or your credentials.

Enable Network Encryption

Typically, wireless network security is delivered through wireless devices (usually a wireless router/switch) that encrypts and secures all wireless communication by default. This security is achieved by WPA /WPA2. WPA2 which has been developed with strong wireless encryption and does not allow the use of an algorithm called Temporal Key Integrity Protocol (TKIP).WPA2 is an improved version over WPA and does not allow the security holes of WPA.

Only WPA2 should be active in the router as WPA sometimes interfere with WPA2. You can check the security of your router at secure.com
Both versions of Wi-Fi Protected Access (WPA/WPA2) can be implemented in either of two modes: Personal mode and enterprise mode.

Personal Mode

When enabling the Personal mode—technically called the Pre-shared Key (PSK) method—of WPA or WPA2 security, you create one unique global password. Everyone enters this same password before connecting to the wireless network. This mode is appropriate for most home networks.

Enterprise Mode

WPA2 Enterprise uses IEEE 802.1X, which offers enterprise-grade authentication. In this setup, there is no shared passphrase. The Enterprise mode of WPA or WPA2 security, however, enables to assign users a unique username and password to log into the Wi-Fi.
