How to FIND THE PASSWORD TO MY Wi-Fi?

I'm at my aunts house on her computer and since my iphone is off i can only use it when i have Wi-Fi and she doesn't know the password: p so how do i find out the password to her Wi-Fi…

Added (1). WHAT's A ROUTER…

Look at the side of her Internet box or modem

On computer that's connected to router type in browser 192.168.1.1 or 192.168.1.2 or 192.168.0.1 type username admin password admin and check Wi-Fi password.

Its on her router unless she changed it

Look at the brand of the router (it's usually box-shaped with lights), make sure its not the modem. Common router brands are linux and netgear. You can google search the brand of the router and customer service number (for example: "Linux Customer Service". And all that number. Ask about your Wi-Fi passcode, the representative will walk you through how to find your code. When you get, write it down, and please note that it's case-sensitive.

Try looking at the bottom or side of the modern if is not there then try these steps

1 Go to Start, click Run and type "cmd" in the field.

2 Look for a black box that will pop up on your screen. At the top, you will see either C:/Documents and Settings/ or C:\Users\(Name)>

3 Type"ipconfig" using the cursor.

4 Hit Enter. On your screen, you will see a series of names and numbers. Look for the line that says Default Gateway. Write down the number that you see next to Default Gateway, including the periods between the numbers (e.g., 912.982.1.5. When you're done, exit the box.

5 Navigate to Google or another search engine. In the address bar, type in the number that you just wrote down.

6 Hit Enter. You will see another screen that has fields to enter your username and password. The username is "admin", and the password is either "admin" or "1234". Enter that information into the appropriate fields.

7 Click the "Log In" button.

8 Go to the Wireless tab on the website that pops up. If you scroll down, you should find something called password. Write down your password and put it in a safe place in case you forget it again.

Some houses have internet but no wi-fi. If your aunt has never used wi-fi, possibly her setup doesn't have it.

If she is has a Router she had to use a password, normally this is a set of number, ei; 000111222,
you can also call the internet provider and they can help you.
