Trouble Changing Wi-Fi Password


I've been following the following steps to change my Wi-Fi password for some time:

1. Launch Control Panel.
2. Click "Network and Internet."
3. Click "Network and Sharing Center."
4. Click "Wi-Fi...."
5. Click "Wireless Properties."
6. Click the Security tab.
7. Check "Show characters."
8. Enter the password in "Network security key."

Those steps have been working just fine, but today I discovered a new wrinkle. If I change the password inside the router first, "Wi-Fi..." doesn't appear in step 4. This isn't much of a problem at home, because I can just change the password in Control Panel before I change it inside the router, but it would be a problem at a public hotspot, or something of that nature. I also tested Brink's instructions in "How to Connect To a Wireless Network in Windows 10," but they don't work for me either. How can I fix this?

unable to deactivate Windows log-on password

Hi HearaldPenkert,

I suggest trying with this steps:

• Swipe in from the right edge of the screen, and then tap Search.
  
  (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Search.)
  
• Enter sign, and then tap or click Change sign-in options.
  
• Choose the sign-in option you'd like to use, and then follow the instructions.

If you're using a local account with a password, you can delete the password to sign in without one. Try this steps:

• Swipe in from the right edge of the screen, and then tap Search.
  
  (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Search.)
  
• Enter sign, and then tap or click Sign-in options.
  
• Under Password, tap or click Change.
• Verify the current password for your local account.
• Leave the New password, Reenter password, and Password hint fields blank, tap or click Next, and then tap or click Finish.

I hope it will solve your issue.

Bye
