HOW TO SECURE YOUR WIFI?

Securing Your WiFi Connection

Introduction:

Securing your WiFi connection is vital to protect your computer files and online activities from unauthorized access. While wireless networks offer convenient internet access without the need for physical connections, they can extend over 300 feet, potentially allowing anyone nearby to access your home network.

Risks:

The risks associated with an unsecured network are significant:

1. Unauthorized Access: Individuals connected to your network can access your hard drive and online activities, potentially compromising sensitive information such as passwords and account numbers.

2. Malware Spread: Computers connected to your network can spread viruses and other malicious software.

3. Legal Implications: If someone using your network engages in criminal activities, the actions could be traced back to your router, potentially leading to legal consequences.

Protecting Your Network:

Step 1: Changing Default Login

After connecting your router, access your router settings through a web-based setup page:

1. Visit the URL provided by the manufacturer, which includes login credentials to access router configurations.

2. Upon accessing the page, locate the "administration" or "settings" section to change your password.

3. Choose a strong password containing a mix of numbers, symbols, and letters. Avoid using personal information or common words. Leaving default login information makes it easier for hackers to gain access to your router settings.

Step 2: Using Encryption

There are two primary types of wireless encryption:

1. WEP (Wired Equivalent Privacy): An older, less secure option, but if it's the only available choice, use 128-bit WEP for better security.

2. WPA (WiFi Protected Access): A more secure and modern option, with WPA2 providing the highest level of protection.

Step 3: Changing SSID

The SSID (Service Set Identifier) is your network's name. Manufacturers often set a default identifier:

1. Access your router's web-based setup page and navigate to wireless settings.

2. Locate the SSID field.

3. Replace it with a unique name. Avoid using personal information, addresses, or identifiable names.

Using default SSID names makes it easier for hackers to target your network.

Step 4: Disabling Broadcasting

Wireless networks typically broadcast their SSID, making them visible to nearby computers. Disabling this broadcast ensures that a person needs both your SSID and password to access your network:

1. You can disable SSID Broadcast on the same page where you configure your SSID name.

2. Select the option to disable or turn it off.

Step 5: Enabling MAC Filtering

Each computer has a unique MAC (Media Access Control) address. Limit access to your network by allowing specific computers to connect:

1. On your router's web-based setup page, locate the Wireless section.

2. Find the MAC filter.

3. Enter the MAC addresses of allowed computers and enable the feature.

Step 6: Reducing WLAN Transmitter Power

Some routers allow you to lower the power of your WLAN transmitter, reducing the signal range. While it's challenging to fine-tune the signal precisely, doing so can limit access to your network from outside your premises.

Step 7: Disabling Remote Administration

Most WLAN routers can be administered remotely via the internet. Use this feature only if you can specify IP addresses with access rights. If not, it's best to keep remote administration turned off, as it could be a security risk.

By taking these precautions, you can significantly enhance the security of your network and prevent common online security intrusions.
