What is Two-Factor Authentication (2FA)?

In today's time when cyber crime and online fraud are increasing very rapidly, it has become very important for everyone to strengthen their online security. Logging in by just entering the password is no longer considered safe because hackers can steal the password in different ways. This is why "Two-Factor Authentication" i.e. 2FA is used. This is a technique that gives additional security to your account. Let's understand it in detail and in simple language. What is Two-Factor Authentication (2FA)? Two-Factor Authentication, called 2FA in short, is an additional security layer that you apply to your account. In this, not only username and password but also another verification method is required to login. That is, even if someone knows your password, he will not be able to login to your account because he will also need another factor (such as OTP or code). How does 2FA work?

How to set up a Wi-Fi network?

Although it may appear difficult, setting up a Wi-Fi network at home or at work is actually easier than you may expect. From selecting the appropriate equipment to resolving typical problems, this guide will take you step-by-step through the whole procedure.

Wi-Fi network

1. Selecting the Proper Tools
  • The router is the central component of your wireless network. It links your gadgets to the internet and transmits the wireless signal.
  • Take into account these elements:
  • Speed: For the quickest speeds, look for routers that support the most recent Wi-Fi standards, such as Wi-Fi 6 or 6E.
  • Range: To guarantee adequate coverage across your house or place of business, pick a router with powerful antennae.
  • capabilities: Some sophisticated routers come with capabilities like beamforming, guest networks, and MU-MIMO, which allows you to connect to several devices at once.
  • Asus, Linksys, Google Nest Wifi, Netgear, and TP-Link are well-known router brands.
  • Your router and the internet are connected via a modem. You will want a different modem if you are utilizing a cable or DSL connection.
  • For information on suitable modem alternatives, contact your internet service provider (ISP).



2. Configuring Your Router
  • Link the modem to the router: Attach the LAN port of the modem to the WAN port of the router using an Ethernet cable.
  • Turn on the network and modem: Await the devices' connection to be established. Typically, this takes a few minutes.
  • Find out the IP address of your router: Usually, a sticker on the router's underside bears this information.
  • Open the router's configuration: In the address bar of a web browser, enter the IP address of your router.
  • Open the admin page on your router and log in: Make use of the router's default login credentials, which are often provided in the documentation.
  • Set up your wireless network:
  • Select an SSID (network name): Other devices will see your network like this.
  • Choose a secure password: Symbols, numerals, and capital and lowercase letters should all be used in a strong password.
  • Select a security protocol: The most secure alternatives are WPA2/WPA3.
  • Restart the router after saving your changes.
3. Linking Equipment to Your Wireless Network
  • On your gadget: Navigate to the Wi-Fi settings and choose your network name from the list of networks that are accessible.
  • Put your Wi-Fi password in here.
  • Check the quality of your internet connection: Try visiting a website by opening a web browser.




4. Improving Your Wireless Network
  • Determine where your router should be placed: The router should be positioned in the middle, away from walls and other obstacles. Keep it away from electrical equipment that can disrupt the transmission.
  • Use a Wi-Fi analyzer app: These programs may assist you in locating signal weak spots and determining which channels are ideal for your network.
  • Think about utilizing a mesh network or Wi-Fi extender: These gadgets help strengthen the signal in hard-to-reach places in your house.
  • Update the firmware on your router: This guarantees that the most recent security fixes and performance enhancements are installed on your router.
Troubleshooting Common Wi-Fi Issues
  • Slow internet speeds: Check your internet speed with a speed test. If the issue is with your Wi-Fi, try moving closer to the router or restarting your router and modem.
  • Weak signal: Check for obstructions between your devices and the router. Consider using a Wi-Fi extender or mesh network.
  • Dropped connections: This could be caused by interference from other devices, outdated firmware, or hardware issues. Try restarting your router and modem, and check for any interfering devices.



Extra Advice
  • Establish a guest network so that visitors may access your internet connection without having access to your primary network.
  • Use a VPN: A VPN increases the security of your internet traffic by encrypting it.
  • Turn on MAC address filtering to limit only authorized devices from accessing your network.
You may effectively set up a dependable and secure Wi-Fi network for your house or place of business by following these instructions.
