How to Change a Wireless Internet Password

By Daniel Hatter

When 802.11, the standard wireless networking technology, was developed, a system of security was developed along with it. Wired Equivalent Privacy (WEP) was designed to provide 64-bit encryption (later 128 and 256-bit) for all data transferred through a network. Not long after its introduction, however, security flaws were found that made it easy to defeat the encryption and access the network. Wi-Fi Protected Access (WPA and WPA2) were designed as replacements for WEP. They use highly advanced encryption methods. Because many older devices still use WEP security, it is still supported by most wireless routers today. If you believe your network's security has been breached or if you just want to switch to WPA or WPA2 security, your wireless Internet password must need be changed.

Things You'll Need

  • Wireless router
  • Router documentation

Step 1

Open an Internet browser. Type in your router settings access address in the address bar. Hit "Enter." The most common addresses are "," "" and "" Consult the router's documentation if needed.

Step 2

Type in the username and password for your router when prompted. Common combinations are "admin" and "admin," "admin" and a blank password field, and "admin" and "password." Consult your router documentation if these combinations don't work.

Step 3

Open the "Wireless Settings" page from the left navigation pane or similarly named page; it may vary slightly between manufacturers.

Step 4

Select "WPA," "WPA2," or "WPA + WPA2" (if available this is the most secure option) from the list of security options, and then type your new password into the "Password" or "Passphrase" field. Click "Apply" to implement your new wireless password and/or security technology.
