Secure Wi-Fi Setup for Home Workers

Table of Contents

Why Home Wi-Fi Security Matters
  • A lot of UK businesses are now offering their employees the option to work from home.
  • Employees are using their own home networks to access business emails and files, and are also connecting to various business systems via the internet.
  • Most people's home Wi-Fi is much less secure than what you would find in the average office.
  • However most of the time, businesses overlook the need to secure their employees' home internet connections.
  • If an employee's home network isn't secured, then employees' sensitive workplace information is at risk of being compromised.
  • If hackers successfully gain access to an employee's home network, they could potentially obtain confidential company information and also access the company's systems via that employee's Wi-Fi.
  • People need to keep in mind that their home network is now part of their job site or office.
  • Securing your home Wi-Fi network does not require an advanced knowledge of technology.
  • Just a few simple steps can greatly increase your home network security.
Common Risks of Unsecured Home Networks

Weak Wi-Fi Password

  • Enabling unauthorised people to connect to a network is very easy when using a simple password.

Router Default Settings

  • Many routers come out of the box with a:
  • Router username
  • Router password
  • Both of these can easily be compromised because they are common.

Router Outdated Firmware

  • Just as PCs and laptops require firmware upgrade, routers also require firmware updates, and without firmware updates, there are security vulnerabilities.

Guest Networks That Are Not Secured

  • If the settings on the guest network are not configured properly, it may allow unauthorised access to the primary network.

Neighbors or Intruders

  • If an outsider is able to connect to your Wi-Fi, they may:
  • Use your internet connection
  • Gain access to shared devices
  • Conduct attacks

Data Interception Risks

  • Uns'e`cure networks are susceptible to having an attacker monitoring and/or intercepting data between devices.
What Makes a Wi-Fi Network Secure
  • Ways To Keep Your Home Wi-Fi Network Secure
  • Secure Home Wi-Fi:
  • Strong Password
  • Keep Router Software Up to Date
  • Encryption (Use WPA2 or WPA3)
  • Limit Access to Trusted Users Only
  • Have a Separate Network for Guests
  • Control Who Can Connect and Protect What They Share.
Essential Steps to Secure Home Wi-Fi
1. Change the Default Username/Password on Router 2. Set Up a Strong Wi-Fi Password 3. Use Modern Encryption (WPA2 or WPA3)
• Log in to your router (via web browser usually)
• Change the default admin username and admin password 		• Use at least 12–16 characters long
• Mix letters, numbers, and symbols
• Avoid personal or commonly used names and phrases 		• Found under router settings
• Do not use older encryption methods such as WEP
4. Ensure Your Router Has Updated Firmware 5. Disable Unused Features 6. Create a Guest Wi-Fi Network
• Check for updates every few months
• Enable automatic updates if supported 		• Disable remote access if not needed
• Disable WPS if the feature is not in use 		• Use for visitors and temporary devices
• Protects your main network from threats on guest devices
Router Security Basics Explained Simply
  • Your home internet connection uses a router. Your router is what gives other devices access to your home wifi network. The router is also how other people (outside of your home) have access to your wifi.
  • If your router is not secure:
  • People can tap/steal from your wifi
  • Your devices are at risk of being compromised
  • There is potential for your internet connection to be stolen and/or misused.
  • Basic Router Security Principles:
  • Change default passwords and usernames
  • Use a strong password for your wifi network
  • Keep your router/firmware up to date; check for regular updates every few months
  • Limit access to only those who need access
Password and Encryption Best Practices
  • An example of a strong password:

Instead of:

  • homewifi123

Use:

  • H0me!WiFi#Secure2026

Bad Practices

  • Never use the same password twice
  • Use a password manager whenever possible.

Encryption Explained Simply

  • The Current Standard is WPA2
  • The most Secure Method is WPA3
  • Choose the strongest option available.
Securing Work Devices on Home Networks
  • Devices must be secured, even if you have secured Wi-Fi.

Do:

  • Keep devices up to date
  • Have antivirus/endpoint protection installed
  • Lock your device when not in use
  • Use work accounts when conducting work activities

Avoid:

  • Use public Wi-Fi to conduct your work
  • Share your work devices with other members of your family
Additional Protections for Remote Workers
  • Using a VPN (virtual private network) to encrypt your internet connection makes it harder for others to intercept your data.
  • Using 2-Factor Authentication (MFA) adds an extra step (i.e., using a code that is texted to you) when logging in.
  • You should only be accessing sensitive files through approved cloud storage and should not save sensitive files on local devices. You should also avoid emailing confidential information unless absolutely necessary.
Home Wi-Fi Security Checklist
  • Change router’s login credentials
  • Set strong Wi-Fi passwords
  • Enable WPA/WPA2/WPA3 encryption
  • Update router’s firmware regularly
  • Create a guest network for visitors
  • Disable any features that are not being used
Remote Worker Security Checklist
  • Keep all device software updated
  • Use antivirus/anti-malware software
  • Lock all devices when not in use
  • Use a VPN when needed
  • Enable multi-factor authentication
  • Avoid using public networks for work
Router Setup Checklist
  • Router’s admin password changed
  • Wi-Fi password is set to be a strong password
  • Router is configured with encryption turned ON
  • Router firmware is up to date
  • Router’s guest network is configured properly
  • Router’s remote access feature is turned OFF.

FAQs

Change access controls from the default setup, create a strong password, enable WPA2/WPA3 wireless encryption and regularly update your router firmware.

Public Wi-Fi is generally considered unsafe. It is best to avoid using public Wi-Fi altogether unless you can connect through a VPN.

Not necessarily; however, using a VPN at home will further secure your internet connection.

WPA3 is the most recent and will offer the best protection; however, if it’s unavailable, then use WPA2.

There is no exact guideline for updating router firmware; however, most manufacturers recommend checking for and installing firmware updates every two to three months or by using automated firmware update features where they are available.

About This Guide

This guide demonstrates how workers can secure their at-home Wi-Fi networks from hazards while accessing company systems and data. The guide identifies some common hazards using weak passwords, using old routers, and using unsecured public Wi-Fi. The guide outlines practical ways to lessen the risk of security breaches for each risk. The guide also explains important security measures such as strong encryption (WPA2/WPA3), updating the firmware, enabling MFA, and securing work devices. This guide has been designed so non-technical users can easily understand how to perform security maintenance on their home networks. The Computer Support Centre is providing this guide to assist UK SMEs and remote workers in improving the security level of their home networks.

Conclusion

  • Securing wireless networks at home is one of the easiest and most efficient ways to secure your organisation.
  • You can make some simple adjustments to:
  • Prevent unauthorised people from accessing your network
  • Safeguard confidential information
  • Reduce the chance of being attacked by cyber-criminals
  • It’s not an option for small and medium enterprises that have remote workers in the
  • UK; it is now essential.
  • If there is any doubt about whether your employee has set up a secure internet connection at home, then the time to review their equipment is before you have to fix it!
