Modern wireless network security standards require constant attention from users, especially when working with the operating system Windows 10A common situation arises when a laptop simply refuses to connect to a home router, displaying the error "Unable to connect to this network." This is a classic sign of incompatible encryption settings between the access point and your device's network adapter. In most cases, the problem stems from the automatic selection of a protocol that is not supported by the current hardware.
Understanding that, How to change WiFi security type, is a critical skill for any PC user. You don't need to be a system administrator to perform this procedure, but knowing the basic principles of network protocols will help you avoid mistakes. Microsoft's operating system provides built-in tools for managing these settings, hidden deep within the system settings.
In this guide, we will go through the process of changing encryption parameters in detail, and consider the differences between the standards. WPA2 And WPA3, and we will also explain why old methods of protection like WEP are no longer relevant. You'll learn how to diagnose the problem and force the required security type for a stable connection.
Basic types of encryption and security protocols
Before making any changes to the settings, it's important to clearly understand which protocols you'll be working with. The security type determines the algorithm that encrypts the data transmitted between your laptop and the router. The most common standard today is WPA2-Personal, which uses an encryption algorithm AESThis is a reliable and time-tested option, supported by almost all devices.
A newer and more advanced standard is WPA3, which is gradually replacing its predecessor. It provides better protection against brute-force password attacks and encrypts data even on open networks. However, if your laptop or network adapter is several years old, it may simply not recognize this protocol or refuse to work with it.
- 🔒 WPA2-Personal (AES) — the gold standard of security, compatible with 99% of devices.
- 🛡️ WPA3-Personal — the latest protocol with enhanced security, requires modern equipment.
- ⚠️ WEP — an obsolete and insecure standard that is strongly discouraged from use.
- 🔄 WPA/WPA2 Mixed - compatibility mode that allows you to connect old and new devices simultaneously.
It's important to note that choosing the wrong encryption type can not only result in no internet connection, but also a significant reduction in data transfer speed. For example, using the TKIP instead of AES often limits WiFi speed to 54 Mbps, which is critical for modern tariffs.
⚠️ Attention: Changing the security type on your router (not just your laptop) will require reconnecting all devices on your network. Make sure you know your WiFi password, as in some cases the system may ask for it again after changing the protocol.
Diagnostics of current network parameters
Before changing anything, you need to know what settings are currently set. Windows 10 provides a convenient interface for viewing the connection status. This will help you understand why the system cannot establish a connection with the specified settings. It often happens that the router is configured to operate only in wireless mode. WPA3, and the laptop's network adapter is trying to use the old protocol.
You can use the command line to get detailed information about your current connection. This is a quick way to find out the network's SSID, radio channel type, and, most importantly, the current security type. Open the command line as administrator and enter the command to list saved profiles.
netsh wlan show profilesOnce the list of networks is displayed, find the name of your WiFi and use the following command to view it in detail:
netsh wlan show profile name="Your_Network_Name" key=clearIn the report that opens, find the section Security settings. The authentication type and encryption type will be indicated there. If you see there 802.11n or 802.11ac in combination with TKIP, this may be the cause of speed problems. Ideally, it should be specified AES.
Instructions: Changing the security type through the control panel
The most reliable way to change the security type for an already saved network is to use the classic Control Panel. WindowsThe modern settings interface ("Options") often hides advanced options, so we'll need access to the legacy interface. This method allows you to force the system to use which protocol to use for a specific access point.
To get started, open the Start menu and start typing "Control Panel." Go to the section Network and Internet, then select Network and Sharing Center. In the left part of the window, click on the link “Change adapter settings”. Find your wireless adapter (usually it’s called “Wireless Network” or Wi-Fi), right-click on it and select "Status".
In the window that opens, click "Wireless Network Properties." Here you'll see a list of the components used by this connection. Look for "Internet Protocol Version 4 (TCP/IPv4)" in the list—this isn't what we need. We're looking for a button or tab related to security, but the path is a bit confusing in Windows 10. It's often easier to delete the network and reconnect it with the correct settings, but there's also a manual way through the registry or adapter properties.
☑️ Action Algorithm
However, a more direct way to change the security type (Authentication) is often hidden. If you want to change the settings for the current network, the easiest way is to "Forget" the network. Right-click the WiFi icon in the system tray, select "Network," find your network in the list, and click "Forget." After this, when you reconnect, Windows will prompt you for a password and attempt to select the optimal security type automatically, or allow you to select one manually the first time you enter the password.
| Parameter | Recommended value | Old meaning (problematic) | Influence |
|---|---|---|---|
| Security type | WPA2-Personal | WEP / Open | Critical to protection |
| Encryption type | AES | TKIP | Speed and stability |
| Opening hours | 802.11 ac/ax | 802.11 b/g | Transfer speed |
| WPS | Disabled | Included | Network vulnerability |
Configuration via registry and group policies
For advanced users who need to hard-code security for corporate networks or specific hardware, editing the registry is an option. This method requires caution, as incorrect changes can disrupt the network subsystem. Windows. We will be changing the network profile settings stored in the system.
Open the registry editor by typing regedit in the Run menu. Follow the path HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles. This is where the profiles of all the networks you've ever connected to are stored. You need to find the profile with the desired network name (parameter ProfileName). There may be security-related settings inside the profile folder, but most often Windows manages these dynamically.
⚠️ Warning: Directly editing the registry without creating a restore point may cause system instability. We strongly recommend backing up the registry or creating a restore point before making any changes.
A more secure alternative method for managing WiFi policies is to use the command line with administrator privileges. You can export the current network profile to an XML file, edit it in a text editor (by changing the tag authentication or encryption), and then import it back. This gives you complete control over the parameters.
netsh wlan export profile name="Network_Name" folder="C:\Temp" key=clearAfter editing the file (replace the values with the desired ones, for example, WPA2Personal), perform the import:
netsh wlan add profile filename="C:\Temp\File_name.xml"What do the tags in the XML profile mean?
In the XML file tag
Troubleshooting connection errors after changing protocols
After you change the security type, your laptop may continue to return errors stating that the network settings do not meet requirements. This happens because Windows Caches old connection settings. The system "remembers" that the network previously operated with one encryption type and attempts to use that data, ignoring the router's new settings.
The first step should always be clearing the network cache. Open Settings (Win+I), go to Network & Internet -> Wi-Fi. Click Manage known networks. Find your network in the list, click it, and select Forget. This will delete the saved profile and all its security settings.
If the problem persists, it's worth checking the network adapter drivers. Adapter manufacturers (e.g., Intel, Realtek, Qualcomm Atheros) regularly release updates that improve compatibility with new encryption standards. Go to Device Manager, find your wireless adapter, right-click it, and select Update Driver.
- 🔄 Reset your network settings via Settings -> Network & Internet -> Status -> Network Reset.
- 🔌 Reboot your router by unplugging it for 10-15 seconds to reset its internal cache.
- 📡 Make sure your laptop is in a strong signal area, as a weak connection can mimic a security error.
Frequently Asked Questions (FAQ)
What's the difference between WPA2 and WPA3, and is it worth switching?
WPA3 provides more reliable protection against brute-force attacks and encrypts traffic even on open networks. It's worth upgrading if all your devices support this standard. If you have older devices, it's better to leave the WPA2/WPA3 Mixed compatibility mode.
Why does Windows say "Can't connect to this network" after changing settings?
Most likely, an old network profile with outdated security settings has been saved on your computer. You need to "Forget" this network in your Wi-Fi settings and reconnect it using the password.
Is it possible to change the security type without accessing the router?
No. The security type (WPA2, WPA3) is set on the access point (router). On a laptop, you can only configure compliance with these requirements or delete a saved profile, but you cannot change the network encryption protocol itself.
What to do if your laptop doesn't see a WPA3 network?
Your network adapter or its drivers may not support the new standard. Try updating your WiFi drivers. If your hardware is older (manufactured before 2018), it won't be able to work with WPA3, and you'll need to switch your router to compatibility mode.
