In the field WPA/WPA2 Key or Wireless Password A unique character set is specified that is used by default. This method only works if you haven't previously changed the default settings to your own.
If the sticker has been removed or the settings have been changed, but a Windows computer is already connected to the network, you can view the connection information in the connection properties. Right-click the network icon in the system tray and select Network and Sharing Center. Next, follow the link with the name of your wireless connection and click the button Wireless network properties.
In the window that opens, switch to the tab SecurityAt the bottom of the screen you will see a field Network security key, where the symbols are hidden by asterisks. Check the box next to the item Show entered characters, and the system will display the password you're looking for in plaintext. This method allows you to quickly restore access without logging into the router's admin panel.
⚠️ Note: If you've changed your password before and haven't written it down, the information on the sticker will be invalid. In this case, logging into the web interface or resetting your password will be the only solution.
Logging into the D-Link router web interface
To view and change wireless network settings, log in to the device's web configurator. Open any browser on a computer connected to the router via cable or WiFi. In the address bar, enter the gateway IP address, which is the default for all models. DIR-300 most often equal 192.168.0.1 or 192.168.1.1The exact address can be found on the same sticker on the bottom of the case.
After loading the authorization page, the system will request the administrator login and password. On older firmware versions, the default login is admin with an empty password field. In newer versions of the software, especially with the updated interface, the factory administrator password is also indicated on the sticker (field Admin Password). If you changed this data and forgot it, you won't be able to access the settings without resetting it.

Factory reset (Hard Reset)
If you've lost your admin panel password and the default one isn't working, or if you want to completely clear the configuration of errors, you'll need to perform a factory reset.

Plug the router into a power outlet and wait for it to finish booting (about 1-2 minutes). Press and hold the button inside the hole for 10-15 seconds. The lights on the front panel should blink or go out, indicating the reboot and memory clearing process has begun. Release the button and wait for the device to fully boot up.

☑️ Checklist before resetting your router
Table: D-Link Standard Access Data
For your convenience, below is a table of the most common factory login and network connection data. Please note that the individual data (especially the WiFi password) is unique to each device and is printed on its label.
| Parameter | Default value | Where to find |
|---|---|---|
| IP address | 192.168.0.1 | On the sticker / Instructions |
| Admin login | admin | On the sticker |
| Admin password | (empty) or admin | On the sticker (for new models) |
| SSID (Network Name) | DIR-300_XXXX | On the sticker |
| WiFi password | Unique key | On a sticker (WPA Key) |
Access problems and their solutions
A common issue is the inability to open the settings page even with the correct IP address. This can be caused by a static IP address on the computer's network card that doesn't match the router's subnet. Ensure that the IPv4 protocol properties are set to obtain addresses automatically. Antivirus software or firewalls can also sometimes block access to local management pages.
Another nuance concerns firmware versions. On some older models DIR-300 With firmware version 1.xx, the interface may differ from newer versions 2.xx or 6.xx. If you can't find the menu item you need, try updating your router's firmware to the latest version, available on the manufacturer's official website.
If none of these methods help, the device may have a hardware fault or a corrupted file system. In such cases, it's recommended to contact a service center or replace the router, as persistent malfunctions may indicate impending hardware failure.
What should I do if my router doesn't save my new password?
If the settings are reset after entering a new password and clicking "Save," the device's log file may be full or the flash memory may be damaged. Try performing a factory reset first, then immediately change the WiFi password before setting up the internet. If the problem persists, a device reset is required.
Is it possible to find out the password if I am not connected to the network?
For security reasons, it's impossible to find out the current password remotely without physical access to the router or connected device. Encryption protocols don't transmit keys in cleartext over the air. The only option is physical access to the device to reset it.
Is it safe to use WPS to connect?
WPS technology is convenient, but it has known vulnerabilities. Attackers can brute-force the PIN code and gain access to your network. It is recommended to disable WPS in your router settings (Wireless -> WPS), if you are not using it right now.
