How to Add a Password to Your Wireless Internet

Edited by Carolyn Barratt, Maluniu, Teresa, Genius_knight and 6 others

Article Edit Discuss

One way to make sure that you are safely browsing online is to add a password to your wireless Internet connection. When you add a password to your wireless Internet connection, it encrypts the data that travels from connected devices to the Wi-Fi router. The most common types of encryption used for wireless Internet connections, or Wi-Fi, are Wireless Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) and WPA2. Here's a guide for how to add a password to your wireless Internet connection for some added security.

Edit Steps
1. 1
  Access your wireless router. Ideally, you can do this with the setup disc that came with your router, but routers are also designed to be accessed remotely through the Internet.
  - You should connect your computer to your router via an ethernet cable in an open port. Most routers have 4 ports. After that you can access all of your routers by going to your "Home" IP address. In your Internet browser of choice, type in 192.168.0.1 (or 192.168.1.1) in the URL or address bar. This should bring up a login and password prompt window. The default password for most routers is "admin" and you should type that into both fields. If this doesn't work, try leaving on field blank and typing admin into the other. If that fails, consult any available support for your specific router manufacturer.
2. 2
  Choose "Security Settings" or "Advanced Settings" in your router's online setup system. There should be a choice to add encryption to your Wi-Fi.
3. 3
  Select WPA2-Personal (which also could appear as WPA2-PSK) wireless encryption, if your router offers it. Some older routers don't have this option.
4. 4
  Choose AES algorithms for WPA2-Personal.
  - AES stands for Advanced Encryption Standard and is the best set of algorithms for wireless encryption. The other common choice, TKIP or Temporal Key Integrity Protocol, is an older set of algorithms that is good, but not as secure as AES. Some argue that TKIP uses more bandwidth for its encryption.
5. 5
  Enter your new login and password credentials. Every device that attempts to connect to your wireless Internet connection will have to enter these to gain access.
  - Your password should be a combination of letters, numbers and symbols. The more basic your password protection is, the easier it is for someone to guess, or "brute force crack," as hackers call it. There are password generators online that will create strong password protection for you, if you need them.
6. 6
  Save your new settings and refresh your router. To refresh your router turn off the power and count to 10. Then turn it back on and let it run through its boot cycle (you'll know its done when all the lights on the front are done flashing).
  - Make sure to add your new login and password credentials to all devices that regularly access your wireless Internet connection. For added Wi-Fi security, you can change your password protection every 6 months or so.
Edit Video

Edit Tips
- If your router does not offer WPA2, select WPA rather than WEP. WPA2 is currently the most secure encryption method for wireless Internet connections. If you can only select between WEP and WPA, choose WPA. WEP is very old and easily bypassed by modern technology.
- Another good way to add Wi-Fi security is to change the network name or SSID. Your wireless router has a default SSID name. Anyone trying to steal Wi-Fi access can easily search for default network names and attempt default passwords or brute force cracking. You can turn broadcasting of your SSID off completely so that no one can see that you have a Wi-Fi connection.
- Make sure to turn on your router's firewall. Some routers have it turned off by default, but this is an easily added level of Wi-Fi security.
- Make sure to note your password somewhere safe, in case you need it again.

2
Right after the bios is finished, hit F8 (or F2,F10,F12)
3
Select 'Safe mode' or 'Safe mode with networking support'
4
Windows will boot up to the logon screen. Click administrator, 9/10 there is no password.
5
Open Command Prompt. You can go to Start > Run and type cmd.exe or simply search for cmd using the Windows search function.
6
Type net user and press Enter. This will bring up a list of user accounts. Look here for the name and exact spelling of the account whose password you wish to change.
7
Type net user name goes here *. Do not neglect any of the spaces (particularly the one before the *) or the command won’t work.
8
Press Enter. Once submitted, the command will give you the option of typing a new password for the user.
9
Carefully type the desired password and press Enter. The characters will not display as you type, so make sure the Caps Lock isn’t on and be very thorough with the spelling and punctuation.
10
Retype the password to confirm. This should weed out any typos.

Press Enter. The new password should go into effect immediately. If you get an error message or your access is denied, the account you’re working on doesn’t have high enough authorization to change any passwords. See Tips for possible solutions.
