This tutorial will show you how to change the connection and security settings of an existing known Wi-Fi network profile in Windows 11.
Wi-Fi is a wireless local area network (WLAN) technology and standard that uses high-frequency radio waves to provide wireless Internet and network connections to your Windows device.
When you connect to a Wi-Fi network for the first time, Windows will automatically add a profile for the Wi-Fi network in "Manage known networks". The saved profile contains the SSID (network name), security key (password), and connection and security properties used to connect to this specific Wi-Fi network.
Sometimes you may need to update or change connection and security settings of an existing known Wi-Fi network profile without deleting the profile and starting over. For example, change the password (security key) or use WPA3 instead of WPA2 security type for the profile to match any changes made to the adapter settings.
Here's How:
1 Open Settings (Win+I).
2 Click/tap on Network & internet on the left side, and click/tap on Wi-Fi on the right side. (see screenshot below)
3 Click/tap on Manage known networks. (see screenshot below)
4 Click/tap on the known Wi-Fi network profile (ex: "Brink-Router2") you want to make changes to its connection and/or security settings. (see screenshot below)
5 Click/tap on the Edit button for Advanced Wi-Fi network properties. (see screenshot below)
6 In the Connection tab, make the changes below you want for this Wi-Fi network: (see screenshot below)
- Check or uncheck Connect automatically when this network is in range.
- Check or uncheck Look for other wireless networks while connected to this network.
- Check or uncheck Connect even if the network is not broadcasting its name (SSID).
7 In the Security tab, make the changes below you want for this Wi-Fi network, and click/tap on OK (see screenshot below)
- Select the Security type in the drop menu.
- Select the Encryption type (if applicable) in the drop menu.
- Type the Network security key (password).
8 You can now close Settings if you like.
That's it,
