In one sentence, describe what the following article is about:

Click or double-click the app icon for your preferred web browser to do so. It's at the top of the web browser window. If there's any text in the address bar, remove it before proceeding. Type in the address you found next to the "Default gateway" (Windows), "Router" (Mac), or the "ip r" ending numbers (Linux). For example, you might type something like 192.168.1.1 here. Doing so takes you to your router's page if the router is online. Type in the username if asked, then type in the password and press ↵ Enter.  If you don't know the login information, don't panic—most routers require you to log in using factory-default credentials (e.g., "admin" for the username and "password" for the password). You can usually find these credentials on the back/side of the router or in the router's manual. If you can't find the router's sticker or its manual, you can check the router's model number online to see what common login credentials are. Especially if this is your first time accessing your router's page, it may take a few seconds for the page to finish loading. Once you're logged in, you can assign a static IP address to your computer. You may need to navigate through some on-screen setup prompts or a tutorial if this is your first time opening the router's page.

Summary:
Open a web browser. Click the address bar. Enter your router's address. Press ↵ Enter. Log into your router's page. Wait for your router's page to load.
