What are the risks of not securing my WiFi network?
Not securing your WiFi network can lead to unauthorized access by malicious individuals. They can intercept your data, utilize your internet bandwidth, or even engage in illegal activities while connected to your network. This can result in legal implications for you and compromises your privacy and security.
Furthermore, an unsecured WiFi network can leave connected devices vulnerable to malware and hacking attempts. Personal information stored on computers or devices may be exposed, leading to identity theft or financial loss. It’s essential to take proactive measures to protect your network to mitigate these risks.
How do I access my router’s settings?
To access your router’s settings, you first need to connect to your network, either via WiFi or by plugging in an Ethernet cable. Open a web browser and enter the router’s IP address in the address bar, typically something like 192.168.1.1 or 192.168.0.1. You can find this information in the router’s manual or on a label attached to the device.
Once you’ve entered the IP address, you’ll be prompted to log in. Use the default username and password, often found in your router’s manual or on the router itself.
