Many users encounter confusion over the names of wireless technologies when trying to set up a home network or connect a laptop to the internet. The question often arises of how to convert WiFi to WLAN, although technically, these terms refer to the same wireless data transmission technology. The difference lies only in the marketing names used by different equipment manufacturers and in the specific operating modes of network adapters, which may not be obvious to the average user.
In fact, WLAN (Wireless Local Area Network) is a general term describing a wireless local area network, while WiFi is a trademark and standard that enables this network. However, operating system interfaces, drivers, or router menus sometimes contain switches that allow you to select a priority protocol or compatibility mode. Understanding these nuances will help you configure your equipment correctly and avoid connection issues.
In this article, we'll explore why your computer or router may display a network as a Wi-Fi network, and how to adjust settings to ensure proper Wi-Fi operation. We'll cover driver settings, router parameters, and system registries to help you manage your connection as efficiently as possible.
⚠️ Note: Settings interfaces may vary significantly depending on the network adapter manufacturer (Intel, Realtek, Broadcom) and operating system version. Always verify menu item names with the documentation for your specific device.
What is the difference between WiFi and WLAN?
To begin with, it is important to clearly distinguish between the concepts to avoid further confusion when setting up equipment. IEEE 802.11 — is a set of standards developed by the Institute of Electrical and Electronics Engineers that defines the rules for building wireless networks. It is these standards that underpin the technology we all know as WiFi.
Term WLAN is broader and describes the network type in general, regardless of the specific data transfer standard. In the Windows operating system, for example, the wireless network icon is often labeled "Wireless Network" or WLAN, giving users the false impression that they don't have WiFi enabled. In fact, if you see a fan or antenna icon, your WiFi is already working; the system simply uses the generally accepted technical name for the network type.
Sometimes confusion arises due to adapter operating modes. Some older or specialized devices may support modes other than standard WiFi, such as proprietary protocols from specific manufacturers. In such cases, switching to "WiFi" or "802.11 b/g/n/ac" mode becomes necessary to ensure compatibility with modern routers.
Checking the current connection status in Windows
Before making any changes to the system, you should verify that the adapter is indeed malfunctioning or using an unwanted mode. In Windows, network interfaces are managed through the Control Panel or System Settings. Open the Start menu, select "Settings," then go to "Network and Internet."
Here you'll see your connection status. If the adapter is enabled but the network isn't found, the issue may be with the drivers or a physical switch on the laptop. Click the link Configuring adapter settingsto open the classic network connections window. This displays all available interfaces, including wired and wireless.
Please pay attention to the name of your wireless adapter. It may contain the words Wireless, WiFi, 802.11 or WLANThis name doesn't affect functionality, but it helps identify the device in the list. If the adapter icon has a line through it or is grayed out, it means the device is disabled, either software- or physically.
To get detailed information about your current connection, use the command line. Launch Terminal as administrator and enter the command ipconfig /allIn the list, find the section corresponding to your wireless adapter. The MAC address, connection status, and assigned IP address will be displayed here.
Configuring wireless adapter properties
If you want to change the adapter's operating parameters to force it to use specific WiFi standards, you'll need to access the driver's advanced properties. In the Network Connections window, right-click your wireless adapter and select "Properties." In the window that opens, click the button. Tune, located in the upper right corner.
Go to the "Advanced" tab. This is where you'll find a list of settings that control how the app works. network cardThe list can be quite extensive, and parameter names are often given in English, even if the system is localized in Russian. Look for parameters with the words "Mode," "Wireless Mode," "802.11n Mode," or "Preferred Band."
By changing the "Wireless Mode" setting, you can limit or expand the range of supported standards. For example, selecting a mode 802.11ac or WiFi 6 This will force the adapter to ignore older and slower networks and operate only in the high-speed range. This can be useful in noisy environments.
☑️ Check adapter settings
You can also find the "Roaming Aggressiveness" setting here. Increasing this value will make your laptop more actively search for an access point with a stronger signal, which is useful when moving around a large house with multiple routers. However, for desktop computers, it's best to leave the default value or set it to the minimum.
⚠️ Warning: Changing the settings in the "Advanced" tab may result in loss of connection to the router if the selected mode is not supported by your hardware. Remember the original settings so you can restore everything as it was.
Changing regional settings and channel
One common reason users search for a way to "create WiFi" is the inability to connect to a network of a specific band or channel. This is often due to regional restrictions. Different countries legally allow different frequencies and signal strengths. If your adapter is configured for a region where channel 13 is prohibited, but your router is distributing WiFi on that channel, you won't be able to connect.
To fix this, in the same adapter properties (Advanced tab), find the "Country Region" or "Regulatory Domain" setting. Changing this setting may unlock additional channels. However, be careful: setting the wrong region may violate local laws and interfere with other services.
It's also important to consider the difference between the 2.4 GHz and 5 GHz bands. Older devices may display as 802.11b/g WLAN, while modern networks operate in the 5 GHz band (802.11ac/ax). Switching the priority to 5 GHz often resolves connection speed and stability issues.
The table below compares the main characteristics of the ranges so you can choose the optimal operating mode for your needs:
| Characteristic | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 450 Mbps | Up to 6900 Mbps (WiFi 6) |
| Range of action | Tall, breaks through walls | Lower, passes obstacles worse |
| Workload | High (microwaves, Bluetooth) | Low, lots of free channels |
| Compatibility | Supports all devices | Only modern adapters |
Why is 5GHz better for gaming?
The 5 GHz band has significantly less interference from household appliances and neighboring routers. This ensures more stable ping and eliminates micro-drops in the connection, which is critical for online gaming.
Driver conflicts and software reinstallation
Often, problems with network display or the inability to select the desired mode are caused by outdated or corrupted software. The operating system may be using a standard Windows driver that does not provide access to all the features of your WiFi moduleIn this case, replacing the driver with the official one from the manufacturer may restore the missing settings.
To update the driver, open Device Manager. You can do this by right-clicking the Start button. Find the "Network Adapters" section, expand it, and find your device. Right-click and select "Update driver," then "Search automatically." However, this method rarely finds the latest versions.
A more reliable way is to download the driver from the laptop or motherboard manufacturer's website. Look for your device model in the "Support" or "Downloads" section. Please note that for some adapters (e.g., Intel Dual Band or Realtek RTL) there are separate management utilities that can intercept control from Windows.
If updating doesn't help, try completely uninstalling the device from Device Manager (select "Uninstall device" and check "Delete the driver software"), then restart your computer. The system will attempt to reinstall the driver, which often resolves software configuration errors.
Router setup: standards priority
The problem may not be with your computer, but with the router's settings. If you want all devices to operate in WiFi mode, make sure your router's wireless network settings don't include legacy compatibility modes, which could force the network into WLAN legacy mode. Access the router's web interface, usually accessible at 192.168.0.1 or 192.168.1.1.
In the Wireless Settings section, find the "Mode" or "Wireless Mode" option. Here, you can select Mixed mode, which allows any device to connect, or a forced mode (e.g., 802.11n/ac/ax only). Selecting "Only N" or "Only AC" will force older devices to search for a different network but guarantee high speeds for new ones.
Also check your security settings. Outdated encryption is being used. WEP or WPA (TKIP) may limit network speed and performance. It is recommended to always use WPA2-PSK (AES) or WPA3, if your devices support this standard. This will ensure maximum protection and performance.
⚠️ Note: Changing the router's security settings or operating mode will disconnect all connected devices. You will need to re-enter the WiFi password on each device.
Common problems and their solutions
Even after proper configuration, situations may arise where the network drops or becomes unstable. One common cause is power saving. Windows may disable the WiFi adapter to save power, which can lead to connection drops. To disable this feature, open the adapter's properties (via Device Manager), go to the "Power Management" tab, and uncheck "Allow the computer to turn off this device to save power."
Another issue is an IP address or DNS conflict. If the network is active but the internet isn't working, try resetting your network settings. Open the command prompt as administrator and run the following commands: ipconfig /flushdns And netsh winsock resetAfter executing the commands, be sure to restart your computer.
If all else fails, there may be a physical fault with the antenna or the WiFi module itself. In laptops, antenna wires can become disconnected from the contacts, dramatically reducing signal strength. In such cases, replacing the module or using an external USB WiFi adapter is the only solution.
How to check signal strength?
In the command prompt, enter netsh wlan show interfaces. Find the "Signal" line—it will display the signal strength percentage. A value below 40% is considered unstable.
Frequently Asked Questions (FAQ)
Is it possible to completely rename WLAN to WiFi in the system?
Technically, it's possible to rename the protocol's system name in the Windows registry, but this has no practical benefit and can disrupt network services. WiFi and WLAN are the same thing, just different names. It's better to focus on connection stability, not names.
Why can't my laptop see the 5GHz network?
Most likely, your network adapter doesn't support the 802.11ac or 802.11ax standard, which operate in the 5 GHz band. Check the adapter model specifications on the manufacturer's website. If it does support it, make sure the "2.4 GHz Only" mode isn't selected in the driver.
Does the network name (SSID) affect WiFi speed?
No, the network name (SSID) is simply an identifier for users and does not affect the technical data transfer speed or connection stability. However, using Cyrillic or special characters in the name may cause compatibility issues with older devices.
How do I know which WiFi driver is installed?
Open Device Manager, find your adapter, right-click it, and select "Properties." Go to the "Driver" tab. The version, development date, and software vendor will be listed there.
Should I delete old WiFi network profiles?
Yes, this is a good practice. Accumulating old profiles can slow down the connection process and create conflicts if you use the same names for different networks. You can delete them from the command line with the command netsh wlan delete profile name="Network_Name".
