Many routers come with default SSIDs that reveal the model of the device. This makes it easier for malicious people to exploit known flaws.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Customize identification and protect access<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Start by changing the SSID to something that doesn't list your operator or address. Avoid names like \"Casa123\" - get creative! For the <strong>password<\/strong>, combine:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Minimum 12 characters<\/li>\n\n\n\n<li>Upper and lower case letters<\/li>\n\n\n\n<li>Special symbols (#, @, %)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Essential technological barriers<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In the <strong>settings<\/strong> from the router, activate <strong>cryptography<\/strong> WPA3 (or WPA2 if not supported). This layer encrypts all the data being transmitted. Complement it with <strong>firewall<\/strong> integrated - it acts as a guardian against invasion attempts.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Action<\/th><th>Benefits<\/th><th>Frequency<\/th><\/tr><tr><td>Change SSID<\/td><td>Hides router model<\/td><td>1 time<\/td><\/tr><tr><td>Update password<\/td><td>Block old accesses<\/td><td>Every 3 months<\/td><\/tr><tr><td>Check encryption<\/td><td>Protects transmitted data<\/td><td>Weekly<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">A study of the <em>Digital Security Institute<\/em> shows that networks with WPA3 reduce exploitable breaches by 82%.

Combine letters and numbers without personal references.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Avoid obvious sequences (date of birth)<\/li>\n\n\n\n<li>Don't repeat the same <strong>access<\/strong> to the network<\/li>\n\n\n\n<li>Keep your new credentials in a safe place<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This change makes it more difficult for attackers to exploit known loopholes.

Activate WPA3 or WPA2 encryption on your router to block intruders.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h3>Q: Why should I update my router's firmware regularly?<\/h3>\n<div>\n<div>\n<p>A: Updates correct security flaws and improve protection against threats. Manufacturers release patches for discovered vulnerabilities, keeping your equipment resistant to cyber attacks.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h3>Q: What is the advantage of creating a separate network for guests?<\/h3>\n<div>\n<div>\n<p>A: This isolates guest traffic, preventing unknown devices from accessing sensitive data from your main network. Use temporary passwords and limit access to resources such as printers or shared files.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h3>Q: How does a VPN help increase security?<\/h3>\n<div>\n<div>\n<p>A: It encrypts all internet traffic, even on public networks. This way, hackers can't intercept information such as passwords or bank transaction details.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h3>Q: Do I need to change the router's default username?<\/h3>\n<div>\n<div>\n<p>A: Yes, many models use \"admin\" logins by default, making it easier to break in. Switch to a unique user and combine it with a strong password to make it more difficult for third parties to access.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h3>Q: Does the firewall really make a difference to protection?<\/h3>\n<div>\n<div>\n<p>A: Absolutely. It acts as a filter, blocking suspicious connections before they reach your devices. Activate the option on your router and set up rules to monitor incoming and outgoing traffic.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>","protected":false},"excerpt":{"rendered":"<p>Home Wi-Fi
