How to Check Whether Your Home Wi-Fi Is Secure

Most people set up their Wi-Fi router once and never think about it again. That is understandable — but a few simple checks can make sure your home network is not leaving the door open for strangers.

The Most Important Setting: Encryption Type

Your Wi-Fi encrypts the data travelling between your devices and your router. The strength of that encryption depends on the security type you are using. There are three common ones:

  • WPA3 — the best, used on newer routers.
  • WPA2 — solid and widely used; perfectly good for most homes.
  • WEP or WPA (without the 2) — outdated and insecure. If you see this, change it.

To check which one you are using, log in to your router (the instructions are below) and look under Wireless Security settings.

How to Log In to Your Router

  • Open any web browser on your computer.
  • Type 192.168.0.1 or 192.168.1.1 into the address bar (the right one for your router is printed on its underside). If the label does not show the address, or the address does not work, your internet provider’s router may use a different one. You can often find the router’s address in your computer’s network settings, in the details of your Wi-Fi connection. Where that screen sits differs by device and version, so look for a line about the router, which may be called the gateway. When you have the right address, a login page for the router should appear and ask you to sign in.
  • Enter the admin username and password — again, on the sticker on the router if you have never changed them.

Key Things to Check

  • Change the default admin password. Every router comes with a generic admin password like “admin” or “password.” If you have never changed it, do so now. Next time you log in to the router, you will need the new password. Anyone who connects to your Wi-Fi could log in to your router and change your settings.
  • Use a strong Wi-Fi password. Your Wi-Fi password should be at least twelve characters with a mix of letters and numbers. Avoid using your address, phone number, or names. Once you change the Wi-Fi password, your devices will usually disconnect and need the new password to reconnect.
  • Check if remote management is off. Remote management lets people log in to your router from outside your home over the internet. Most people do not need this, and it should be disabled. Look for it under Advanced or Remote Access settings.
  • Check what devices are connected. Most routers have a page showing all connected devices. Look through it. If you see anything you do not recognise, it could be a neighbour using your Wi-Fi — change your password.

Keep Your Router’s Firmware Updated

Router manufacturers release updates that fix security problems, just like your phone gets updates. Log in to your router and look for a Firmware Update option, usually under Advanced or Administration. Update it if one is available. Some newer routers do this automatically.

Before you update, keep the router powered on and do not switch it off or unplug it while the update runs. Only update from the router’s own admin page, not from a link or file sent to you by someone else. If the update fails, or the router does not work properly afterwards, contact the router maker’s support, or your internet provider if they supplied the router.

Get help if you cannot log in to your router, even after checking the address and login details described above, or if a device you do not recognise keeps reconnecting after you change your Wi-Fi password. Use the contact route described in the firmware section above.

A Quick Summary Checklist

  • Security type is WPA2 or WPA3 (not WEP)
  • Admin password has been changed from the default
  • Wi-Fi password is strong and unique
  • Remote management is disabled
  • Connected devices list looks familiar

Running through this list takes less than fifteen minutes and significantly reduces the chance that someone unauthorised is using or snooping on your home network.
