  1. Connect a computer to the router (Wi‑Fi or Ethernet).
  2. Open a browser and go to the router’s admin page (commonly http://192.168.31.1 or http://192.168.1.1). Log in with admin credentials.
  3. In the dashboard, find and click “Settings” or “Advanced settings.”
  4. Locate “Guest network” (may be under Wireless or Wi‑Fi settings).
  5. Click “Add guest network” or toggle to enable the Guest SSID.
  6. Configure:
    • SSID: Enter a clear name (e.g., “Home-Guest”).
    • Security: Choose WPA2-PSK or WPA2/WPA3 mixed if available. Avoid open (no password) unless you have a captive portal or temporary event use.
    • Password: Set a strong, easy-to-share password (8+ characters).
    • Access type: Select “Internet only” or enable Guest Isolation to prevent access to LAN devices.
    • Duration / Limits (if available): Set session timeout or bandwidth limits to control usage.
