How to log into the admin panel of the D-Link DIR-300 router?

Question

network hardware

I go to 192.168.0.1, enter admin/admin or admin/ and characters from the picture and all the time I get "Login or password is incorrect". Did a hard reset, all to no avail. When I try to log in via telnet, it says that the connection could not be established. netstat -an does not show port 23. What else can I try?
Thanks in advance.

Try to reset using the 30-30-30 method: Hold the reset for 30 seconds with the router turned on, without releasing the reset, pull out the power and hold it for another 30 seconds, return the power without releasing the reset and hold it for another 30 seconds. Then reboot the router and try to log into the admin panel again.
Or maybe the firmware is dead. Try to reinstall the firmware according to the following instructions
