1. Preparing to change your password: what you need to do before entering settings

Before changing your password, make sure your computer or smartphone connected to the router via cable or Wi-Fi. If you have already forgotten the current network password, connect via LAN port (yellow connectors on the rear panel DIR-615). This ensures access to the control panel even without knowing the current security key.

Also check:

• 🔌 Router power supply: indicator Power should be green or blue.
• 🌐 Internet connection: bulb Internet (or WAN) should not flash red.
• 💻 Router IP address: usually it is 192.168.0.1 or 192.168.1.1 (check the sticker on the bottom of the device).

If you're connected via Wi-Fi but don't remember the password, you can temporarily reset the router to factory settings. To do this, press and hold the button Reset (10-15 seconds) until reboot. After resetting, the network name (SSID) will become dlink or DIR-615, and the password is admin or empty (depending on revision).

2. Login to the D-Link DIR-615 admin panel

To change your Wi-Fi password, you need to access your router's web interface. Open any browser (Chrome, Firefox, Edge) and enter the router's IP address in the address bar. Typically, this is:

192.168.0.1

or

192.168.1.1

If the page does not open:

• 🔍 Make sure you are connected to the router (check the network settings on your PC).
• 🔄 Reboot your router (turn off the power for 30 seconds).
• 📋 Check the IP on the sticker under the device or via the command ipconfig (for Windows).

After entering your IP address, an authorization window will appear. Enter:

• 👤 Login: admin (default).
• 🔑 Password: admin or leave the field blank (depending on the firmware version).

⚠️ Attention: If you have previously changed the login/password for entering the panel and have forgotten them, reset the router to factory settings (button Reset). After the reset, the login data will become default.

3. Step-by-step instructions: how to change your Wi-Fi password

After successfully logging into the control panel, go to the section Wi-Fi → Security Settings (in some firmware versions the path may differ: Wireless → Security). Here you will see the current network parameters.

Follow the steps:

1. In the field Network name (SSID) You can keep the old name or come up with a new one (for example, MyHomeWiFi_5G).
2. In the section Network authentication select WPA2-PSK (the most reliable option for home networks).
3. In the field PSK encryption key (or Wi-Fi password) Enter a new password. It must contain:
   • 🔢 Minimum 8 characters.
   • 🔤 Latin letters (uppercase and lowercase).
   • 🔢 Numbers or special characters (!@#$%).

Click Apply or Save (button at the bottom or top of the page).

The new network name (SSID) is correct|

Encryption type - WPA2-PSK (not WEP!)|

The password contains letters, numbers and symbols|

Connected devices are ready to reconnect-->

After saving, the router will reboot (this is normal). All devices will be disconnected from Wi-Fi, and you'll have to reconnect with the new password.

⚠️ Attention: If your internet connection disappears after changing your password, check your settings. DHCP in the section Network → LAN. Make sure the option is Enable DHCP server active.

4. Selecting optimal security settings

Many users leave the default settings, but this can weaken network security. Let's look at the key settings in the section Wi-Fi → Security Settings:

If your DIR-615 supports WPA3 (relevant for new revisions), select WPA2/WPA3-PSKThis will ensure compatibility with old and new devices.

What is WPS and why is it better to disable it?

WPS (Wi-Fi Protected Setup) is a feature for quickly connecting devices using a PIN code or a push-button. However, it has some vulnerabilities:

- An 8-digit PIN code can be guessed in a few hours.

- Many routers use standard PINs (for example, 12345670).

- Attacks via WPS can block the router (DoS).

Recommendation: Disable WPS in the section Wi-Fi → WPS or More → WPS.

5. Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when changing their password. Here are the most common issues and their solutions:

• 🔄 The router does not save settings: Check that you pressed Apply, and not just closed the tab. If the problem persists, reset your browser's cache or try a different one (Firefox, Edge).
• 📶 Wi-Fi disappears after changing the password: Make sure you haven't disabled Wi-Fi sharing in the section Wi-Fi → Basic Settings. Check if the transmitter is turned on (Enable wireless connection).
• 🔑 The new password does not work.: You may have entered it incorrectly or used Cyrillic. The password must be only in LatinTry resetting your router and repeating the setup.
• 🛡️ Devices do not connect to the network: If you have chosen WPA3, and the gadget does not support it, go back to WPA2-PSKAlso check if MAC address filtering is enabled.

If after all these manipulations the Internet still doesn't work, try roll back the firmware to the factory version. To do this, download the latest firmware from the website D-Link (Please specify the exact model, for example, DIR-615/N1) and update the router through the section System → Software Update.

6. Additional security measures for the D-Link DIR-615

Changing your Wi-Fi password is just the first step to securing your network. To minimize the risk of hacking, take a few more steps:

• 🔐 Change the administrator password: By default this is adminGo to . System → Administrator Password and set a complex password (for example, D1r-615_Adm!n2026).
• 📡 Update the firmware: Outdated versions may contain vulnerabilities. Check if your software is up to date. System → Software Update.
• 🚫 Disable remote control: In the section System → Remote Control Make sure the option is turned off (if you don't use it).
• 🕒 Set up a Wi-Fi schedule: If you don't need the network at night, turn it off. Wi-Fi → ScheduleThis will save energy and reduce the risk of attacks.

We also recommend disable guest network, if it's not in use. Guest networks often have weak security settings and can become a backdoor for hackers. Find it in the section Wi-Fi → Guest Network and deactivate.

⚠️ Attention: If your DIR-615 Supports dual-band mode (2.4 GHz and 5 GHz). Set up separate passwords for each band. This will increase security, but will require devices to be connected to the correct network.

7. How to connect to Wi-Fi after changing the password

After saving the new settings, all devices will be disconnected from the network. To reconnect:

1. On Windows: Click on the Wi-Fi icon in the tray → select the name of your network → enter a new password.
2. On Android/iOS: Go to Wi-Fi settings → tap on the network → enter the key.
3. On Smart TV or set-top boxes: Go to network settings → select your SSID → enter the password.

If the device does not connect:

• 🔄 Reboot it (especially relevant for smart TVs and printers).
• 📱 Forget the network in your device settings and reconnect.
• 🔧 Check if it is enabled on your router MAC address filter (if yes, add the device's MAC to the whitelist).

For devices without a screen (eg. smart speakers or IP cameras) you may need to reset their network settings. This is usually done by long-pressing the button Reset on the device itself.
