How to Change Your Wi Fi Password

How to Change Your Wi Fi Password

Wi-Fi is great for keeping you connected, but a poorly secured Wi-Fi can put your personal information at risk. Keeping your router password-protected and changing the password regularly is an essential key to protecting your network and your data.

Change Wi Fi Password

It also keeps cheap neighbors from stealing your bandwidth! See Step 1 below to learn how.


1. Open your router's configuration page. You can access your router's configuration page through a web browser on a computer connected to your network. If you can't connect via Wi-Fi because you don't know the password, use an Ethernet cable to connect your computer directly to the router. This will bypass the need for the Wi-Fi password.
  • Standard router addresses are,, or (Apple).
    Enter the address into your browser's address bar.
  • If none of the above addresses grant you access to the configuration page, open the Command Prompt by pressing ? Win+R and entering cmd. Once the Command Prompt opens, type ipconfig and press ? Enter. Look for your active connection in the list and find the Default Gateway address. This is typically your router address.
  • If all else fails, press and hold the Reset button on your router for about 30 seconds to revert it to factory default settings. Then, look up the default address for that router model and enter it into your browser.
  • Some routers come with configuration software. If you've previously installed your configuration software, you can use that instead of the web browser interface.

2. Enter your router's username and password. Every router will require a username and password before you can access the innards. If you never changed this when you first configured the router, chances are the username is "admin" and the password is "admin" or "password". Of course this varies from model to model, so you should search your model online to see your exact login info.
  • If you've changed the login in the past and since forgot it, or received the router as a hand-me-down and the previous owner didn't reset it, you'll need to press and hold the Reset button on the router for about 30 seconds. This will reset the settings to default, allowing you to log in with the default username and password.

3. Open the Wireless section. Once you are logged into your router, you will need to find the Wireless section of the configuration page. The exact name changes from manufacturer to manufacturer, but generally you are looking for a Wireless or Wireless Settings/Setup tab or button.
  • If your "Wireless" section has multiple subsections, open the Wireless Security page.

4. Change the password. Look for the box labeled Password, Passphrase or Shared Key. You can enter your new password into this box. Some routers will ask that you type the password again to ensure that you entered it correctly.
  • Try to create a strong password that would be difficult if not impossible to guess. It should not be related to anything personal, and should include a liberal amount of numbers, random cases, and special characters such as "!", "$" and "#".
  • A strong password is usually at least 8 characters long.

5. Check out your security type. There are three main types of wireless encryption: WEP, WPA, and WPA2. For the most secure network, you should be using WPA2. You may run into issues connecting older devices, however, in which case you could switch to WPA or WPA/WPA2. Selecting WEP is NOT recommended, as WEP encryption is very easy to break (it can take less than 30 minutes to crack a WEP password).

6. Change your network name. While you're here, take a moment to change your network name if you have not already. The name should not include any personally identifiable information, as the name will be publicly broadcast. Changing the name will help deter people from trying to break into it. Routers with default names are seen as easier hacking targets.

7. Save your settings. Once you are done entering in your new password, click the Apply or Save button. The button's location is different for every router, but is typically located at the top or bottom of the page. The router will take a few moments to process the change, at which point any devices currently connected would be disconnected.
  • After your settings are changed, you can connect to your wireless network using your new password.
How to Change Startup Programs on Your PC

How to Change Startup Programs on Your PC

Is your computer running more slowly than it used to? It may be because you have enabled too many startup programs, that is, programs that launch automatically when you start your computer. These programs can bog down your system resources, and removing them can free up space.

Change Startup Programs

This article provides methods for users of Windows, Mac OS, and GNU/Linux.

Method of Windows 7

1.) Open up the Run dialog box by:
Opening the start menu and clicking "Run" or
Pressing the Windows Key and "R" at the same time.

2.) Type in msconfig in the text box.
Then click "OK" or press "Enter".
A dialog box will pop up with various tabs. By default, it's on the General tab.

3.) Click Startup.
Click on the "Startup" tab. This shows the different programs that start up when you turn on your computer.

4.) Disable programs.
Get to work disabling the programs that you don't want starting up automatically. Be careful not to disable anything important. Look up programs first if you are unsure.

5.) Click "OK" once you've finished disabling the automatic programs.
For example, if you don't want iTunes starting up automatically, just uncheck iTunes.exe.

6.) Check the Startup folder.
Be aware that startup programs are also stored in a folder called "Startup." Click on the start menu, go to "All Programs," and select "Startup." Chances are that there is nothing in there, but there could be some programs, so it's worth checking.
If you don't want any of those programs to start up, simply right-click the file(s) you don't want and select "Delete."

Method of Windows 8

1.) Open the task manager.
You can do this by pressing Ctrl+Alt+Del or by searching for it using the search bar in your Charms menu.

2.) Click the Startup tab.
You will see a tab in the Task Manager window which says "Startup". Click it.

3.) Disable programs as necessary.
Be careful not to disable anything important. Look up programs first if you are unsure.
More options are also available if you right-click on the item.

4.) Add programs.
You can also add programs by adding shortcuts to the Startup folder on your computer. The address for the startup folder should look something like this: "C:\Users\Tuklu\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup". Just replace "Tuklu" with your user name for your PC.

Method of Mac OS X

1.) Go to your computer's dock and access "System Preferences."

2.) Click "Accounts" in the Menu.

3.) Click the "Login Items" tab.

4.) Click the item you want to remove and click the minus button.
If you want to add something, press the plus button and select the application.

Method of GNU/Linux

1.) Edit the scripts in /etc/init.d.
This directory contains a number of start/stop scripts for various services on your computer system.

2.) Use rcconf if you want software help.
This tool configures system services in connection with system runlevels. In other words, it will help you turn services on/off using the scripts in /etc/init.d.
If you're running the Ubuntu operating system, you can use the settings from here: System -> Preferences > Startup Applications.
  • Be sure to use common sense when disabling the programs. For example, if it's iTunes.exe, you can tell that that is related to iTunes. Just don't overestimate your common sense.
  • Another totally free software toolbox is CCleaner, available from or from the author at Software. On the Tools tab, you can stop startup programs from running (both ones in the Startup folder and ones starting from elsewhere), as well as uninstall unwanted programs.
  • A free alternative to WinPatrol is Autoruns from the Sysinternals suite. It has the same and more features as Winpatrol and it is free. (Sysinternals is part of Microsoft.)
  • If for some reason doesn't have what you're looking for, you can always try using a search engine to look for the information you need.
Warning: Be sure that you have a good idea of the process. Even though there is nothing in startup that your computer needs in order to run, you may temporarily lose access to some of your software if you are not careful.
