If you suspect your network has been hacked, it's crucial to take immediate action to protect your information and secure your network.

Here are the steps you can follow:

1. Disconnect from the network: Disconnect the affected device from the internet or disconnect the entire network to prevent further unauthorized access.

2. Change passwords: Update the wireless password and login passwords for all network devices, including routers, modems, and Wi-Fi access points. Use strong, unique passwords that are not easily guessed. Avoid using the same password for different platforms.

3. Update firmware and software: Ensure that all network devices, including routers and connected devices, have the latest firmware and software updates installed. These updates often include security patches that address vulnerabilities.

4. Run antivirus and anti-malware scans: Scan all devices, such as computers, smartphones, and IoT devices, using reputable antivirus and anti-malware software. Remove any identified malicious software.

5. Use access control allow list: Consider configuring access control on your Wi-Fi router to only allow specific client devices. This helps prevent unauthorized devices from connecting to your network. How to configure Access Control on the Wi-Fi Routers
