how can we use netgear router settings remotely?

On your computer or smartphone ,login into your netgear router settings

and for that you need to open your browser and type this address:- https://routerlogin.net or 192.168.1.1

enter your login information(default username is admin and password is password)

once you are logged in, then go to the advanced tab and then select advanced setup option

click on the remote management option and turn on this feature and under the allow access , select everyone.

and then hit apply.

To turn on remote management:

1. Log in to the router, if you haven't already done so.
2. Click Advanced > Remote Management.
3. Select Turn Remote Management On.
4. Decide whether to give router access to one computer, or several computers in a range of IPs. (You probably shouldn't give access to everyone, unless you have a dial-up connection and a dynamic IP.)
5. If giving access to only one computer, select Only This Computer, and type the computer's IP.
6. If, instead, you want access to a range of IPs select IP Address Range and type the beginning and the end of the range in the From and To boxes. In this example, the starting IP is 68.205.2.56, and the ending IP is 68.205.2.65.
7. 1. Leave Port Number at the 8080, unless behind a corporate firewall that blocks some ports. Ports that are not typically blocked are for HTTP and HTTPS outbound traffic, port numbers 80 and 443.
   2. Click Apply.
   3. Write down the IP shown in the Remote Management Address box. This is the address, followed by the port number, that gives remote access to the router. E.g., in this example http://68.203.2.57:8080.

   Accessing your router from the Internet, type your router's WAN IP into the browser, followed by a colon (:) and the
   port number. E.g, if your external IP is 134.177.0.123 and you use port 8080, enter http://134.177.0.123:8080.
