I can not enter the settings of the router.

Good day!

I can not enter the settings of the router. Router address: http://192.168.1.1 (this has been verified for sure). Opera browsers, edzhe and all the rest. OS: Vin 10. Sagemcom f @ st router (Rostelecom). In the settings of the tcp / ip protocol, everything is configured to automatically obtain addresses (it was also registered manually and did not help). The router responds well. From another device (a tablet also through the opera), it goes into the settings of the router normally. An attempt was made to fix this using the Windows Repair program and after the program was running, it was possible to enter the router settings, but after the reboot, it again does not enter the router settings.

What other correction options can there be (except for resetting the router settings, because it's not about it)? Thank you in advance.
