Wondering how to tell if your Wi-Fi has been hacked? A compromised router can put your entire network at risk, leading to data theft, slow internet speeds, and unauthorised Wi-Fi access. Here’s how to identify if your router has been hacked.
1. Unusual Slow Internet Speeds
If your internet suddenly slows down despite no significant network activity, a hacker might be using your bandwidth for malicious activities.
2. Unknown Devices on Your Network
Check your router’s admin panel for unfamiliar devices. If you spot unknown IP addresses or MAC addresses, someone might be connected without your permission.
3. Altered Router Settings
Hackers may change DNS settings to redirect your traffic to phishing sites. Log in to your router and check if the DNS settings match your ISP’s default values.
4. Frequent Disconnections
If your Wi-Fi keeps disconnecting or your router reboots randomly, an attacker might be controlling it remotely.
5. Unexpected Pop-Ups and Redirects
Frequent browser redirects or pop-ups could mean your router’s DNS settings have been compromised.
6. Changed Admin Credentials
If you can’t log into your router with your usual credentials, a hacker may have taken control and changed the login details.
7. Unfamiliar Firmware or Software Updates
Some hackers install rogue firmware to maintain control. Check your router’s firmware version and compare it with the official update from the manufacturer.
8. High Data Usage
Unexplained spikes in data usage might indicate an attacker is using your connection for botnets, crypto mining, or DDoS attacks.
How to Secure Your Router
- Change Default Credentials: Use a strong, unique password for both the Wi-Fi and admin panel.
- Enable WPA3 or WPA2 encryption: Avoid WEP, as it’s outdated and easy to crack.
- Update firmware regularly: Manufacturers release patches to fix vulnerabilities.
- Disable Remote Management: Turn off external access to prevent unauthorised logins.
- Use a firewall: Most routers have built-in firewalls; ensure it’s enabled.
- Monitor connected devices: Regularly check for unfamiliar devices in your network.
By staying proactive, you can prevent hackers from exploiting your router and protect your sensitive data.
Frequently Asked Questions (FAQs)
1. How do hackers gain access to my router?
Hackers exploit weak passwords, outdated firmware, open ports, or remote management settings to gain control of a router.
2. Can I reset my router to remove hackers?
Yes, performing a factory reset can remove unauthorised Wi-Fi access. However, you must change default credentials and update firmware after resetting.
3. How often should I check my router settings?
It’s best to check your router settings at least once a month for any unauthorised changes or unknown devices.
4. What should I do if I suspect my router is hacked?
Disconnect from the internet, reset your router, change passwords, update firmware, and scan devices for malware.
5. Can antivirus software detect router hacking?
Not always. Antivirus software protects individual devices, but router security requires manual monitoring and updates.
