⚠️ Attention: If you change the password while connected to a WiFi network, your device will automatically disconnect immediately after the settings are applied. To continue using the network, you'll need to reconnect and enter the new key.

Logging into the D-Link router control panel

Open any modern web browser. In the address bar, where the website name is usually written, enter your router's IP address. For the model D-Link DIR-615 the most common address is 192.168.0.1. Press the Enter key.

After successfully entering the data, you'll be taken to the main menu of the web interface. The interface may differ depending on the firmware version: it may be gray (old style) or green and black (new Cloud style). Don't be alarmed by the differences; the menu logic remains the same.

Find the Wireless Network (WiFi) section

Router interface D-Link may have a different menu structure. In older firmware versions, the necessary settings are located in the tab Wireless (Wireless Network) In newer versions the menu may be called Wi-Fi or be placed in a separate block on the main page.

You need to find the subsection responsible for security. It's usually called: Wireless Security or SecurityThis is where the fields for entering the encryption key are located. Don't confuse this section with the MAC filtering or IP filtering settings.

In some firmware versions (especially for providers like Rostelecom or Beeline), settings may be hidden in advanced mode. Look for the "Advanced Settings" button to see the full list of available options.

What if the menu is in English?

If your interface is entirely in English, look for the "Wireless" -> "Security" section. Key words: "Pre-Shared Key" (this is your password) and "Security Mode."

Instructions for changing your WiFi password

You can change the SSID to any name you like, using Latin characters. This will help you easily identify your network among your neighbors, especially in apartment buildings where the airwaves are saturated with signals.

You can also configure the wireless channel here. If you live in a house with many routers, automatic channel selection may not work correctly. In this case, try switching to channels 1, 6, or 11, which don't overlap.

⚠️ Attention: The firmware interface may vary depending on the device's year of manufacture and software version. If you don't see the above items, check the official documentation on the manufacturer's website for your specific revision.
