Strengthening home WiFi security: Responding to growing cyber threats

With the popularity of remote work, attacks on home WiFi networks are becoming increasingly rampant, as home networks often store a lot of valuable and sensitive information, and home WiFi security settings are often not enough to deal with these threats. Whether you are a business owner with remote employees, a freelancer working from home, or a regular home user, you need to take steps to ensure your network security.

What security threats does home WiFi face?

Many people think that home WiFi is safer than public WiFi, but that is not necessarily true. Unless you take appropriate security measures, your home network is as vulnerable to attacks as WiFi in public places. Many people have never changed the default settings of their routers, nor have they set complex passwords, enable encryption, filter unknown devices, or use virtual private networks (VPNs).

The following guides will help you improve your home WiFi security:

1. Reset the router to factory settings

First, reset the router to factory settings and clear all custom settings. This removes outdated WiFi security types, closes unnecessary network ports, and changes default login credentials. This step is especially important if you purchased a router from someone else. The reset method varies by router model, please refer to your router manual. It is usually necessary to hold the reset button for about 30 seconds, then wait for 30 seconds before restarting the router.

2. Create a unique username and password

Most routers use "admin" by default as username, which is easily guessed by hackers. Be sure to change the default username and create a strong password. You can use the password manager to generate a long and complex password containing letters, numbers and special characters.

3. Enable a secure WiFi network for visitors

Create a separate WiFi network for visitors, which can effectively isolate the visitor's device and prevent malware from infecting your primary network. Most routers support creating multiple WiFi networks.

4. Use the latest WPA network encryption

Choose the latest WPA network encryption protocol, such as WPA2 or WPA3 (if your router supports it). Avoid outdated WEP encryption.

5. Hide your WiFi network

Hide your SSID (Service Set Identifier) ​​can increase security because only people who know the SSID and password can connect to your WiFi.

6. Filter unknown MAC addresses

Only known devices are allowed to connect to your WiFi network. You can add the MAC address of all devices to the router's allow list. How to find MAC addresses on your Mac: System Preferences ➙ Network ➙ Advanced ➙ Hardware Tab.

7. Limit wireless devices via IP

You can limit the number of devices connected to the network by limiting the size of the DHCP pool.

8. Using a Virtual Private Network (VPN)

Using a VPN can encrypt your connection and prevent data from being stolen. ClearVPN is a recommended VPN client that offers multiple connectivity options and powerful security features.

9. Improve the quality of WiFi connection

Using WiFi analysis tools such as WiFi Explorer and NetSpot, you can monitor WiFi connection quality and optimize the placement of your router to improve WiFi signal strength and coverage.

Through the above steps, you can effectively improve the security of your home WiFi network and enjoy faster and more stable network connections. Tools like ClearVPN, WiFi Explorer, and NetSpot can help you get these settings easier.
