Even if the IP address and the physical connection are confirmed, you may face issues accessing the router page. In this case, there may be an issue with your router itself. Even though most of the settings and configuration-related issues can be handled by resetting the router. You can first perform a power cycle of the router by disconnecting all the wires from behind it and then plugging them back in.
If the power cycle does not work, try a hard reset. This is done by locating the reset button at the back of the router and pressing it down for 10 seconds. Once the lights begin to flash, release the button. When the router restarts, connect with it again and then try to access the router page IP address.
But, even after performing a hard reset of the router, if the issue persists, then it can be a hardware failure. If there is something physically wrong preventing the 192.168.10.1 IP address admin login, then you need to speak with your device’s manufacturers. If it is under warranty, you may be able to get a free replacement.
