You can log in to your ASUS router and access the web GUI by following these steps:
1. Open your favorite web browser and enter your wireless router’s internal IP address which is 192.168.1.1 or navigate to http://router.asus.com.
2. Once you’re on the login page enter your username in the “User Name” field that you’ll see in the dialog box.
3. Type in your Asus account password in the “Password” field.
4. And click on the “OK” button below the password field.
After logging in to your Asus router you’ll see the home screen of the web GUI which looks like this:
And now you can use the web GUI to configure the settings of your ASUS wireless router according to your preferences and needs.
If you have problems signing in you can try to locate your password or recover your username, and if that doesn’t work, then you can try to fix the problem by resetting your ASUS router entirely.
