You will need a web browser to do this. Enter the IP address of the router in the address bar of your browser.
The default address is often "192.168.1.1" or "192.168.0.1". You can also check this address on the bottom or back of the router, or in the user manual.

Once you have entered the IP address of the router into the top search bar window of your browser, you should be prompted for a username and password. Standard login details are often**:

**These may vary depending on the router model.
If you have changed these details before, enter the ones you have set.
