Security has become second nature for people over the years, whether it be your home , car or personal items. Our computers are no exception to this, such as digital thieves are lurking everywhere, and it can be almost impossible to detect by the average computer user. Prevent unauthorized access to your home or business wireless network (Wi-Fi) is an extremely important step to take, as a hacker does not need to know personally target you, and can be in a house or an apartment, or even in a parked car on the road. Wi-Fi hackers have been known to drive around neighborhoods looking for wireless networks in people's homes, have access through different doors open into a wireless router configuration, and then have a field day with your information. In this article, we will go step by step through the different configurations of the wireless router that leave your network vulnerable, and what to change to make your network virtually hacker-proof.
Step 1: The first thing we need to do is access to our router configuration utility. To do so, you must first understand what the IP address of the gateway. You can do this by going to Start> Run and type CMD. This will open a command prompt session. In the command prompt, type 'IPCONFIG' without the quotes and press enter. If done while connected to the network, this will come back different numbers. What we need is listed as "Default Gateway." Take the specified IP address as "Default Gateway" and write it down or copy it. If you're not familiar with IP addresses, it is a series of numbers separated by periods like this: 192.168.1.1 In fact, this particular IP address I only used as an example is the most common port, but yours may be listed as something different. Now, with this IP address is copied, open a web browser such as Internet Explorer or Firefox, and paste or type the IP address exactly as you see in the address bar and press Enter. This will open the login page for the router. If you know the password of them enter here, if not, you will have to find the manufacturer's user ID and password for the router. You can find this in the manual for your router, or by going to the manufacturer's website and search for the manual under the router's model number (this can be found on a sticker on the back, side, or bottom of the router. ) You can try before common ones like "admin" for the user ID and "password" for the password, or "admin" for both the user ID and password. If these do not work, refer to the manufacturer's manual for the user ID and password. If you set your user ID and password and forgotten them, or manufacturer's default user ID and password are not working, if other people in the house have access to the router or had a previous owner, the default user ID and password It may have been changed. In that case, you can bring back to their default values by pressing and holding the reset button on the back of the router for at least five seconds. Now you can log in using the user ID and default password set by the manufacturer.
Step 2: Edit the user ID and password if they are set to default values of the manufacturer. If someone gets access to the wireless network, they can easily access the router settings and alter at will.
Step 3: Change the SSID. Your SSID is the name you see for your wireless network when you perform a search for open networks that use a Wi-Fi enabled device. If the SSID is set to the manufacturer's default, anyone who is looking for an open network can see your neighbor, and with a little 'research on the internet you can figure out the router's model number that will help them access settings router.
Step 4: Disable the SSID broadcast. Broadcasting an SSID is simply the way in which you search open networks in an area, the open networks will show names on the device. If you disable SSID broadcasting, when people search for open networks, your will not even show up, so basically, they will not know the wireless network still exists. It will still be able to connect to the network, by typing the SSID in your Wi-Fi enabled devices manually.
Step 5: If available, enable WPA2 encryption. If WPA2 is not available, enable WPA encryption. If neither is available only WEP is available, manual tuning or Web site of the router for information on how to upgrade your router's firmware. An update to the router may include support for WPA or WPA2. If no update is available for your current router, you may consider purchasing a new router as yours is probably much older. WPA2 is ideal as it is far more secure than WPA and WEP particular.
Step 6: Installation of a Pre-Shared Key or PSK or network key. Whatever your router calls, this is the "password" for your network. This should not be confused with the password that we have changed in step 2 to the router. Your Pre-Shared Key that you set should be impossible to guess, and should include upper and lower case letters, numbers and special characters. It 'very important to include all of these to make it almost impossible to break, but do not make it so long that it takes 5 minutes to get into all devices. If it is difficult to remember, you can always look up every time you need by accessing the settings of the new router.
Step 7: Enable MAC Address Filtering or MAC Address Authentication. This step is optional, and should only be performed if you do not have visitors that use the Wi-Fi network, or devices that use Wi-Fi network are always the same devices. A MAC address is an ID that basically any Internet-enabled device or network has that looks something like: 00: 20: e0: 00: 41: 00. Each device has ever created a unique MAC address so they can be properly identified on a network as an individual. Using filtering MAC Address Authentication or allow only specific devices that are selected for the connection to the wireless network. Any external devices will not be able to connect because their MAC address is not in the list of allowed devices to create. To add a Wi-Fi-enabled devices to access the list, you first need to obtain the MAC address of each device. For computers and laptops, you can simply go to Start> Run and type 'CMD' without quotes. This will open a Command Prompt window. Then type 'ipconfig / all' without quotes, and press Enter. Something to say "Physical Address" should be listed somewhere near the top. Next to it you will see the MAC address of the computer. It can be listed with hyphens in between each two characters instead of two points, as in the previous example. This is fine, just make sure that when you enter the MAC address of the access list that you do in the format required by the router, so you may need to change all the hyphens in two points. Do this for all computers connected to the wireless network. For devices like iPod, iPad, mobile phones, etc., you will have to search for your device information most likely in the Settings menu (or it may be somewhere else depending on the device). Here, if it is a Wi-Fi-enabled device, it will find the MAC address. Do this for all non-computer devices that connect to your wireless network and each add to your access list. Do not forget, every time you buy a new device or visits someone and want to use Wi-Fi, you will have to perform this step.
It 'important to follow the steps to properly secure your wireless network, with the exception of the optional step # 7. There are other security measures that may It is implemented, however, the above points are the most important, and most necessary to prevent unauthorized access to the wireless network. If you have completed all the steps in this tutorial, you can be sure that the wireless network is now virtually impenetrable.
