Wireless Security Tips for WiFi Network

Wireless Security is a major concern these days, with terrorists using open WiFi networks to send bomb blast claims to the government, you could be in some serious trouble.

Although wireless networks are very beneficial, but wireless networking has many security issues. Crackers (loosely called hackers) have found it easier to break wireless WiFi networks. But this can be prevented by some pro Wireless Security Tips.

This article summarize the steps you should take to improve the wireless security of your home WiFi network.

  • Change Default Username & Password of your WiFi

    Most WiFi home networks have an access point or router. To set up these pieces of equipment, manufacturers provide web pages that allow owners to enter their network address and account information to boost wireless security.

    These Web tools are protected with a login screen (username and password) so that only the rightful owner can change this. However, for any given piece of equipment, the login credentials provided are simple and very well-known to hackers.

    Change these settings immediately to prevent your network from getting into the wrong hands & to level up your wireless security.

  • Change the Default SSID (WiFi Network Name)

    SSID or Service Set Identifieris name of your wireless network. Most wireless routers have a predefined SSID like ‘default’ or the brand name of the router.

    Although changing it won’t directly improve your wireless security, but it will prevent hackers from directly knowing what type of router you are using and reduce the possibilities of an attack.

    Also, you might just change your SSID to Hacker Inside or Virus.exe to fend off amateur crackers.

  • Disable SSID (Wireless Name) Broadcast

    By Default, WiFi routers broadcast the Wireless Network Name (SSID). This feature enables you to connect to set up your wireless network easily.

    But, after set up you don’t need this facility as your device will connect to your WiFi automatically. Thus, disabling it will prevent your network from being visible to the public and hence prevent unauthorized access to your network, +1 to your wireless security 😉

  • Enable Wireless Encryption: best for Wireless Security

    All wireless routers have either WPA or WEP encryption to prevent unauthorized access to your network. WPA encryption is much secure than WEP encryption and hence is a preferred mode of encryption.

    If you find your router or your computer incompatible with WPA encryption then you should still apply WEP as something is better than nothing. A newer encryption, WPA 2 provides even stronger encryption than WPA but your hardware needs to support it.

  • Filter Mac Address

    Every laptop, mobile or any other any wireless device has a unique address called MAC address or Media Access Control address. Most WiFi routers have a feature, which if enabled will allow only certain MAC addresses  to access the network.

    Thus you can restrict your router to only allow connections to your own devices. So only you authorized devices will be able to access your network!

  • Decrease the Range of your WiFi

    Wi-Fi signals may leak out of your house and hence your network is detected by the neighboring receivers. To prevent this, you need to decrease the range of your WiFi router.

    This can be done by packing your router with an Aluminium Foil or placing the router in a box. You will have to experiment these things and then set it up according to your needs to minimize the leakage.

    You can add some holes to the box or aluminium foil wrapper if the range of your WiFi becomes way too less for even you to catch it effectively, it’s pure hit-n-trial 😉

  • Enable Firewall on your Computer and Router

    Firewall helps prevent unauthorized access to your wireless network.  Modern routers have inbuilt firewalls but many a times the firewall is turned off.

    Also set up firewall on each computer that connects to the network for added wireless security.

  • Turn off WiFi Router when not in use

    The simplest and the best good way for wireless security, is to turn it off when not in use. Such as when you go out for work or play.

    Turn off wifi & bluetooth to save battery
    Turn off wifi

    This prevents hackers and outsiders from accessing your network. Also, it keeps the router cool and prevents it from getting heated, not to mention the save in electricity bill 😉
