What are the common signs that my Wi-Fi has been hacked?
The common signs that your Wi-Fi may have been hacked include unexpected slowdowns in internet speed, unauthorized devices connected to your network, and frequent disconnections. If you notice that your devices are dropping off the network or experiencing connectivity issues that are unusual, it could indicate that someone else is using your bandwidth without your permission.
Another red flag can be the appearance of strange or unfamiliar activity on your accounts when you’re logged into the Wi-Fi network. This could manifest as notifications of login attempts from users or devices that you do not recognize, which might suggest that someone is accessing your personal information through your compromised network.
How can I secure my home Wi-Fi network?
Securing your home Wi-Fi network starts with changing the default username and password of your router, as manufacturers often use generic credentials which are easily exploited. Opt for a strong and complex password that includes letters, numbers, and special characters. Additionally, ensure that your Wi-Fi encryption method is set to WPA3, or at least WPA2, as these are the most secure options currently available.
It’s also beneficial to regularly update your router’s firmware. Manufacturers release updates to fix vulnerabilities, so staying up to date can enhance your network security significantly. You can also consider utilizing a guest network for visitors which separates their access from your main network and devices, further protecting sensitive information.
What is the difference between WPA2 and WPA3 security protocols?
WPA2 (Wi-Fi Protected Access II) has been the standard for wireless security for many years, providing improved security over its predecessor, WEP. It uses a pre-shared key (PSK) for security, ensuring that unauthorized users cannot easily access the network. However, vulnerabilities have been discovered over time, making it less secure than newer options.
WPA3 is the latest security protocol and offers enhanced protection through a range of features such as improved encryption and protection against brute-force attacks.
