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.

    See our tutorial to Change the Default SSID (Wireless Name)

  • 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 😉

Configure WPA WiFi Security in Windows

WPA2 or Wireless Protected Access 2 is the best form of wireless security for your WiFi internet connection, better than WEP or WPA (its predecessor). But this new type of encryption is neither supported in all Wireless Routers, nor in all Windows versions.

This tutorial will guide you through to ultimate wireless security for your WiFi connection.

Does your Wireless Router support WPA ??

If you have a very old Wireless router, chances are that it will neither support WPA, nor WPA2. Call your router manufacturer support staff and ask if your router can support WPA or WPA2.

Upgrade the wireless router firmware with the support staff’s help, if necessary. If your router doesn’t support WPA or WPA2, stay cool with a WEP encrypted password, no need to go further into this tutorial.

Does your Computer Support WPA ??

For Windows XP Service Pack 1 (Win XP SP1)

Windows XP SP1 does not support WPA by default while it cannot support WPA 2 at all.

To upgrade your computer to support WPA (but not WPA2), either Install Windows XP Support Patch for WPA from Microsoft or upgrade your computer to XP SP2 or SP3.
For Windows XP Service Pack 2 (Win XP SP2)
Your computer supports WPA by default, but not WPA2. To also support WPA2, either install the WiFi WPA2 update for XP SP2 from Microsoft or upgrade it to Service Pack 3.
For Windows XP Service Pack 3 / Vista / 7

Your computer supports both WPA and WPA 2 by default. So directly jump to the next section.

How to Configure WPA2 WiFi Security

1. Open your WiFi router’s administrative console by entering the routers IP address in your browser’s address bar.

If you already haven’t published your Facebook Timeline Profile, do so after cleaning it of any personal activities, by clicking the big green Publish button at the top of your Profile.

WiFi Security – Enable MAC Address Filtering

Most wireless routers have an inbuilt feature called MAC Address filtering. By enabling it, only devices whose MAC addresses are configured in the router can access WiFi, thus allowing for maximum WiFi Security.

By default this feature is turned off, because it requires some steps to be followed for setting it up. After which, your neighbors won’t be able to access your WiFi. 😉

Although it is possible to spoof a MAC address, i.e an attacker could extract MAC address details from your network and pretend to be that device, to connect to your WiFi.

But since its a lengthy & advanced process, so its not followed by many people and thus MAC address filtering will protect you from majority of amateur WiFi hackers.

How to enable WiFi Mac Address Filtering for Optimum WiFi Security??

To enable MAC Address Filtering for your WiFi Router, follow the steps below:

1. Open your WiFi router’s administrative console by entering the routers IP address in your browser’s address bar.
