Bolstering your home security often means door locks, alarm systems and security cameras, but a recent hack of 14,000 home routers shows you need to protect your home internet network too.
Selecting a Wi-Fi router with the latest security protocols and keeping your home network locked down are essential to preventing you from inadvertently helping a major cybercrime network.
If your Wi-Fi network isn’t properly secured, you could be leaving your Wi-Fi wide open to hackers, data thieves and other digital threats. When your home network is breached, strangers could control connected devices, install malicious software or access your sensitive data, such as credit card numbers and camera feeds.
Maintaining a secure home network can also protect against unwanted or unauthorized people and devices slowing down your connection by freeloading on your internet service. The good news is that improving your network security isn’t as complex as you may think.
It’s worth noting that nothing can guarantee absolute security from hacking attempts. But these 10 simple tips below make it much harder for anyone to compromise your network and data.

Tips to secure your Wi-Fi network at home
Here are the basics for protecting your home Wi-Fi network. Keep reading for more information on each below.
- Position your router in a central location.
- Use a strong Wi-Fi password and change it often.
- Change the default router login credentials.
- Turn on the firewall and Wi-Fi encryption.
- Create a guest network.
- Use a VPN.
- Keep your router and devices up to date.
- Disable remote router access.
- Verify connected devices.
- Upgrade to a WPA3 router.
1. Position your router in a central location
Strong network security starts with an optimized setup. If possible, place your router near the center of your home. Routers send wireless signals in all directions, so strategically placing your router in a central location will help keep your connection to the confines of your home. As a bonus, it will likely also make for the best connection quality.
For example, if you have internet in an apartment where neighbors are immediately to the left and right of you, placing your router next to a shared wall could send a strong and tempting signal their way. A good router can cast signals next door or across the street, even if you aren’t in an apartment. Placing your router in a central location reduces how far those signals travel outside your home.
2. Use a strong Wi-Fi password and change it often
This should go without saying, but I will still cover it to emphasize its importance: Creating a unique password for your Wi-Fi network is essential to maintaining a secure connection. Avoid easily guessed passwords or phrases, such as someone’s name, birthday, phone number or other common information. While simple Wi-Fi passwords are easier to remember, they’re also easier for others to guess. You can easily access your router settings to update your Wi-Fi password.
Oh, and be sure to change your password every six months or so, or whenever you suspect your network security may have been compromised. The more frequently you change your password, the less compromised it will be.
3. Change the default router login credentials
Along the same lines of password-protecting your Wi-Fi network, you’ll also want to keep anyone from being able to directly access your router settings.
To do so, change your router’s admin name and password. You can log in to your router settings by typing its IP address into the URL bar, but most routers and providers have an app that lets you access the same settings and information. If you’re unsure how to determine your IP address, read our guide.
Your router login credentials are separate from your Wi-Fi network name and password. If you aren’t sure what the default is, you should be able to find it on the bottom of the router. Or, if it’s been changed from the default somewhere along the way, here’s how to access your router settings to update the username and password.
4. Turn on the firewall and Wi-Fi encryption
Most routers have a firewall to prevent outside hacking and Wi-Fi encryption to keep anyone from eavesdropping on the data sent back and forth between your router and connected devices. Both are typically active by default, but you should check to ensure they’re enabled in your router settings.
Now that you know how to log in to your router settings, ensure the firewall and Wi-Fi encryption are enabled. If they’re off for whatever reason, turn them on. Your network security will thank you.
5. Create a guest Wi-Fi network
Before sharing access to your main home network, consider creating a separate guest network for visitors. I’m not suggesting your guests will attempt anything nefarious with your main Wi-Fi connection. Still, their devices or anything they download while connected to your network could be infected with malware or viruses that target your network without them knowing it.
A guest network is also ideal for your IoT devices, such as Wi-Fi cameras, smart thermostats and smart speakers — devices that may not hold a lot of sensitive information and are perhaps more easily hackable than a smarter device such as a computer or phone.
6. Use a VPN
There are a few reasons to use a good VPN, and network security is one of them. A virtual private network hides your IP address and Wi-Fi activity, including browsing data.
VPNs are most useful when connected to a public network, but they can still add a level of security and privacy to your home network. Some VPNs are better than others, but like anything, you often get what you pay for. Free VPN services are available, but you can get a much more secure service if you pay a few extra bucks a month. Another perk of using a VPN is that it can be great for streaming.
7. Keep your router and devices up to date
Software updates can be annoying, but they often include security updates. When companies become aware of potential or exposed security vulnerabilities, they release updates and patches to minimize or eliminate the risk. Stay updated on downloading those regularly.
Keeping your router and connected devices current with the latest firmware updates will help ensure you have the best protection against known malware and hacking attempts. If possible, set your router to automatically update in the admin settings, and periodically check that it is up to date.

8. Disable remote router access
Remote router access allows anyone not directly connected to your Wi-Fi network to access the router settings. Unless you need to access your router while away from home (to check or change the configuration of a child’s connected device, for example), there should be no reason to enable remote access.
You can disable remote access under the router’s admin settings. Unlike other security measures, disabled remote router access may not be the default.
9. Verify connected devices
Frequently inspect the devices connected to your network and verify that you know what they are. If anything on there looks suspicious, disconnect it and change your Wi-Fi password. After changing your password, you’ll have to reconnect all your previously connected devices, but any users or devices that are not authorized to use your network will get the boot.
Some devices, especially obscure IoT ones, may have odd default names of random numbers and letters you don’t immediately recognize. If you encounter something like that when auditing your connected devices, disconnect them. Later on, when you can’t start your robot vacuum cleaner from your phone, you’ll know that’s what it was.
10. Upgrade to a WPA3 router
WPA3 is the latest security protocol for routers. All new routers should be equipped with WPA3, so if you buy a new router, you should have nothing to worry about. Many people rent their routers directly from the provider, which may not include the most up-to-date equipment.
If your router was made before 2018, you might have a WPA2 device, which lacks the same security protocols as newer WPA3 devices. A quick search of your device’s model should tell you when it came out and any specific features, such as whether it has WPA2 or WPA3. If you’ve got a router with WPA2, call your provider and negotiate for a better, more recent router.
What’s the bottom line? Network security is not guaranteed
Again, even with the most recent and effective methods of protecting your home network, security will never be 100% certain. As long as there is the internet, hackers and cybercriminals will find ways to exploit it. With the tips above, you can better keep your network secure from anyone trying to use your connection or access your data.
