Method 1: Setting a password via the web interface

This is a classic method that works on all firmware versions. DIR-320. Follow the instructions:

  • Go to the section Wi-Fi → Security Settings (in some firmware the path may look like this Wireless → Security).
  • In the window that opens, you need to:

    • 🔒 In the field Network authentication choose WPA2-PSK (recommended) or WPA/WPA2 Mixed (for compatibility with older devices)
    • 📝 In the field PSK encryption key enter a password of length from 8 to 63 characters (use letters, numbers and special characters)
    • 🔄 Click Apply or Save at the bottom of the page

    Encryption type selected: WPA2-PSK|

    Password contains ≥12 characters|

    Vocabulary (word-based) mypassword 🟡 Weak <1 minute
    Mixed (letters + numbers) WiFi320Dir 🟢 Average ~2 hours
    Complex (special characters, different case) D!r320_WiF1#2026 🔵 Strong >100 years

    * Estimated brute-force attack time on an average PC (2023 data)

    For DIR-320 optimal password length - 12-16 charactersAvoid:

    • 📅 Dates of birth, names, and nicknames of pets
    • 🔢 Sequences (12345678, qwertyui)
    • 📱 Duplicate passwords from other services (social media, email)
