How to Reset and Re-Secure a Hacked Home Router

Oh dear, it sounds like your home router might have been hacked. While it can feel a bit scary, the good news is that we can fix this together. This guide will walk you through, step-by-step, on how to reset your router and get your home network secure again.

Recognising a Compromised Router

Before we dive into fixing things, how can you tell if your router has actually been hacked? Sometimes, the signs can be a bit subtle, but other times, they might be glaringly obvious. Knowing what to look for can help confirm your suspicions.

• Unexpected new Wi-Fi networks appearing in your list that you don't recognise.
• Your internet connection is much slower than usual, or drops out frequently.
• You're being redirected to strange websites, even when you type in a correct address.
• Your router's administration page looks different, or you can't log in with your usual password.
• New, unfamiliar devices appearing on your network when you check your router's settings.

Isolating Your Network – Unplug Everything!

The very first, crucial step is to disconnect as many devices as possible from your compromised network. This helps prevent the hacker from potentially accessing other devices in your home while you're trying to fix the router. It's a bit like putting a 'do not disturb' sign on your entire home network.

• Unplug all computers, laptops, and smart devices (like smart TVs, speakers, and security cameras) from your router, both via Wi-Fi and Ethernet cables.
• Turn off your mobile phones' Wi-Fi and switch to mobile data if you need internet access.
• Leave only the device you'll use to configure the router (e.g., a laptop) connected directly to the router via an Ethernet cable, if possible. Otherwise, keep it disconnected until the factory reset.

Performing a Factory Reset

A factory reset will wipe all custom settings and revert your router to its original, 'out-of-the-box' state. This is vital for removing any malicious changes a hacker might have made. It's like giving your router a fresh start.

Most routers have a small button, often recessed, that you'll need to press and hold. It's usually labelled 'Reset' or 'Restore'.

• Locate the reset button on your router (you might need a paperclip or pen to press it).
• With the router powered on, press and hold the reset button for 10-30 seconds (this varies by router, check your manual if unsure).
• Release the button and wait for the router to restart completely (this can take a few minutes).
• Once restarted, your router will be back to its factory default settings, including the default Wi-Fi name and password (often found on a sticker on the router itself).

Setting Up Your Router Securely

Now that your router is clean, it's time to set up new, strong security measures to prevent future attacks. This is your chance to build a virtual fortress around your home network. Don't skip any of these steps!

• Connect your computer to the router using an Ethernet cable (or the default Wi-Fi with the password on the sticker).
• Open your web browser and type in your router's default IP address (common examples are 192.168.1.1 or 192.168.0.1 – check your router's sticker or manual).
• Log in with the default username and password (again, usually on the router's sticker or in the manual). Change this immediately to a strong, unique password.
• Change your Wi-Fi network name (SSID) and create a strong, complex Wi-Fi password (WPA2 or WPA3 security is best).
• Find the 'Administration', 'Management', or 'Security' section and disable 'remote management' if it's enabled. This stops people from trying to access your router from outside your home.
• Check for and install any available firmware updates. Router manufacturers often release updates to fix security weaknesses.
• Consider disabling 'Wi-Fi Protected Setup' (WPS) as it can sometimes be a weak point.

Reconnecting Your Devices and Monitoring

With your router now secure, you can start reconnecting all your smart devices. Take this opportunity to ensure all your devices are also up-to-date and have good security practices in place.

Keep an eye on unusual activity, even after the reset. Ongoing vigilance is your best defence.

• Reconnect your devices slowly, one by one, using your new, strong Wi-Fi password.
• Change the passwords for all your online accounts, especially those connected to your home network (like email, banking, and social media).
• Run a full anti-virus and anti-malware scan on all your computers and devices, just in case.
• Regularly review your router's connected devices list to ensure only your known devices are present.
• Keep an eye on your internet speed and watch out for any strange web page redirects.

Key takeaway

Dealing with a hacked router can feel daunting, but by following these steps, you can successfully reset and re-secure your home network. Remember, a factory reset is your strongest tool, followed by creating robust, unique passwords and staying vigilant. You've taken an important step in protecting your digital home!
