Verify that your computer is connected to the wireless router via an Ethernet cable or wireless connection.
Make sure you know the IP address of the router. Most routers are manufactured to use a default address like 192.168.0.1, 192.168.1.1, or 192.168.2.1.
If those don't work and you're not sure what your specific router's default IP address is, or it's not the default address anymore because you've changed it, please refer to your user manual / guide.
Open a web browser like Internet Explorer, Google Chrome or Firefox, and request a connection to the router using its IP address.
For example, type http://192.168.1.1 in the address bar to connect to a router that has 192.168.1.1 as its IP address.
Enter the administrative login information to authenticate and access the admin settings.
Routers are shipped with default usernames and passwords. This is usually the word admin but might be different for your router (some might not even have a password or might not use a username).
