How to secure your router
Your router is the front door to your home network. A few simple steps will make it much harder for anyone to misuse your connection or see your devices.
1. Change the admin password
The router has two passwords: one for Wi-Fi and one for its settings page. Many people change only the Wi-Fi one. Check the sticker for the default admin login, then change it to something long and unique that you do not use elsewhere. Menus differ between routers, so look for Administration, Password or System in the settings.
2. Use strong Wi-Fi security
Choose WPA3 if your router and devices support it. If not, WPA2 is fine. Avoid options called WEP, WPA or Open, as they are weak or offer no protection.
3. Use a long Wi-Fi password
Use three or four unrelated words with a number. Do not use the same password as anywhere else.
4. Keep it updated
Updates fix security flaws. Many provider routers update themselves, but check whether yours does. If your router is very old, ask your provider about a replacement.
5. Switch off what you do not need
- Turn off remote management or remote access, unless you really need it.
- Turn off WPS if you do not use it.
- Do not open ports or forward them to devices unless a professional has explained the risks.
6. Use a guest network
Give visitors and smart gadgets a separate network. Our guest Wi-Fi guide shows how.
7. Check who is connected
Many routers list connected devices. If you see a name you do not recognise, change the Wi-Fi password.
A warning about resets
A factory reset returns the router to its original settings and erases your Wi-Fi name, password and any changes. Only use it as a last resort, and have your provider details to hand in case you need to set it up again.
Beware of scams
Your provider will not phone you and ask for your router password or ask you to install software. If someone does, hang up and call the number on your bill.
