Tips for optimizing home WiFi signal and security

To improve home WiFi performance, users should place routers in a central location at a height of at least one meter, rather than in corners or on the floor. Obstacles such as mirrors, tiles, water pipes, and electronic appliances like microwaves or televisions can block or interfere with signals due to metal content or frequency overlap.

To check if unauthorized users are accessing a network, the National Cybersecurity Institute (INCIBE) recommends accessing the router's administration panel. Users can find the router's IP address via the command prompt in Windows using the 'ipconfig' command. Once logged into the administration interface, users can view a list of connected devices under sections such as 'Connected Devices' or 'DHCP Clients' to identify any unknown connections.
