| Parameter | Default value | Note |
|---|---|---|
| IP address | 192.168.0.1 | It could be 192.168.1.1 |
| Login | admin | Case is important |
| Password | admin | Changes during first setup |
| Interface | Web-based | Access via browser |
What to do if the default password doesn't work?
If the "admin" password doesn't work, the router may have been configured previously. In this case, you'll need to perform a factory reset. Locate the RESET button on the back panel and press it with a paperclip for 10-15 seconds while the router is turned on. The device will reboot, and the password will return to the factory settings.
