The Easiest Ways to Make Your Home Network More Secure

While there’s no foolproof method for keeping everything on a wireless network completely secure, there are some things you can do to make it safer. In addition to setting up devices that don’t depend on a wireless network, you can use a few other tools to discourage hacking and keep your wireless network more private. Taking a few practical steps can give you some peace of mind when using your home security system or your wifi network.

Use a wired connection to prevent jammers

Wireless cameras for home security are convenient and cost-effective, but it’s a good idea to include some devices that don’t depend on a wireless network—just in case. Because any wireless network is vulnerable to jammers, using devices that don’t use a wireless signal is a good backup measure to take. These can be as simple as window alarms, or can be as extensive as a wired security camera system that records to a DVR. For most people, one or two wired cameras at key entry points like the front and back doors or focused on a garage entrance is sufficient.

In addition to hardwired security devices, you can also choose to use an ethernet internet connection with a firewall to prevent sensitive information on your home computer from being accessed without physically connecting to your network. Ethernet is a wired internet option that is often faster and less glitchy than a wireless connection, and it has the added benefit of being resistant to jamming and hacking as well.

Change your frequency frequently to prevent jammers

Wifi jammers work by interrupting a particular signal frequency. Changing the frequency that your network operates at can help to prevent jammers from latching onto your signal. Frequency-hopping spread spectrum devices are an option that will automatically change the frequency of your wifi signal, making it more difficult to use an RF jammer to disrupt the wifi connection to your home security devices. While FHSS is considered an older, outdated technology for many wifi devices because more modern wifi protections are geared to data protection, it’s useful for preventing jamming attacks. Consumer Reports tested several home security systems for jamming resistance, and there are a few devices that tested well for resistance to frequency jamming including the Honeywell Smart Home Security System. If you’re considering a home security upgrade, you should look for devices that use FHSS technology or a similar frequency changing feature to deter jamming attempts.

Create unique passwords

When you set up your home wireless network, your router likely comes with a password for initial access. Additionally, the administrative password is also generated by the manufacturer as a way to access the settings on your router. These passwords are notoriously easy to discover and are not intended to be a long term solution for network security. Create a password that’s different from the one that came with your device and that also doesn’t contain things like birthdays, addresses, or important dates that could be easily discoverable to strangers.

Create a new name for your network

When you install a new wireless networking device, it likely has a name it was given by the manufacturer. This is a placeholder so that you can set up your network, but you should come up with your own name that isn’t associated with your name or address once you activate it. This will help make it more difficult to find and break into your wireless network.

Turn off remote access controls

Most routers have the option to change settings remotely, allowing you to manage device permissions and settings from a computer not hardwired to the device. In addition, many routers also offer universal plug and play, letting any device that’s plugged into the router access its settings without using a password and WPS (wifi protected setup), allowing you to press a button on your modem for instant connection without entering a password. While all of these features can be convenient, they’re also great ways for someone looking for valuable data or access to security devices to access your network without your knowledge. Disabling these features can help make your wireless network more secure.

Use encryption

Encrypting your network is as simple on newer routers as selecting WPA 3 personal or WPA 2 personal on your network settings. Older routers don’t have these options and are much less secure than newer ones as a result. Using an outdated router makes your network less secure because they aren’t capable of higher level encryption.

Don’t stay logged in

While it’s convenient to stay logged in to your wifi administrator account, you should log out once you’re done setting it up. That’s because anyone who has access to your device—even remotely—can use the administrator account to change your wifi settings and access connected devices including your home security system. If you’re logged out, a would-be hacker needs your password to get into your wifi settings.

Use your firewall

One default setting that your router usually comes with is actually good to leave the way it is, and that’s the firewall. Most routers come with a firewall that’s already switched on to help protect your wi-fi network and connected devices. You should check to make sure it’s on to improve the security of your wireless network.
