How to share Wi-Fi from an ASUS laptop to a phone

Situations where it is necessary to urgently provide network access to a smartphone or tablet arise regularly. ASUS laptopLike any modern Windows device, it has built-in functionality for creating a virtual access point. This allows you to instantly set up a local network using an existing wired or wireless connection.

The main advantage of this method is that there is no need to purchase additional equipment. Built-in adapters Wi-Fi ASUS ZenBook, ROG, and VivoBook series laptops support simultaneous transmit and receive mode. This is critical for stable network operation without data packet loss.

In this guide, we'll cover the two main methods for activating tethering mode. The first method uses the operating system's graphical interface, making it ideal for inexperienced users. The second method uses the command line, allowing for more flexible configuration of security settings and frequency bands.

Before proceeding with the settings, you need to make sure that the network adapter drivers are installed correctly. For ASUS devices, we recommend using the utility ASUS Live Update Or visit the manufacturer's official website to download the latest software versions. This will eliminate possible hardware conflicts when switching antenna modes.

Checking compatibility and preparing equipment

Successfully setting up an access point directly depends on the technical specifications of your equipment. Not all older network card models support this feature. Hosted Network, which is the foundation of the virtual router. Owners of ASUS laptops older than 7-8 years should check the specifications of their adapter in advance.

For initial diagnostics, you can use Windows' built-in diagnostic tools. Open a command prompt as administrator and enter the command netsh wlan show driversIn the list that opens, find the line "Hosted Network Support." If it says "Yes," your laptop is ready to use.

• 📶 Make sure the wireless module is enabled using a physical switch or key combination Fn + F2.
• 🔌 Check that the laptop itself has an active internet connection (via Ethernet or Wi-Fi).
• 🆔 Create a network name (SSID) and a strong password in advance to protect against unauthorized access.

⚠️ Please note: When running on battery power, your ASUS laptop will consume significantly more power in Shared Mode. It is recommended to connect the device to a power outlet to prevent unexpected shutdowns.

It's also worth paying attention to the frequency range. Modern routers and ASUS laptops often operate in the 5 GHz band, while older smartphones can only see 2.4 GHz. When setting up, it's important to select a compatible standard; otherwise, guests' phones simply won't see your network in the list of available ones.

Activating a mobile hotspot via Windows Settings

Starting with Windows 10, Microsoft introduced a user-friendly graphical interface for managing network connections. This method is the simplest and doesn't require extensive technical knowledge. To begin the process, go to the Start menu and select "Settings."

In the window that opens, find the "Network & Internet" icon. In the left menu, select "Mobile Hotspot." This is where you'll find all the necessary switches to turn your laptop into a fully-fledged Wi-Fi hotspot.

First, you need to select your connection source. In the "Internet Connection Sharing" drop-down list, select the adapter your ASUS laptop uses to connect to the internet. This could be an Ethernet cable or an existing wireless connection.

Next, you need to configure security settings. Click the "Edit" button to set the network name and password. It is recommended to use the encryption standard WPA2-Personal, as it provides reliable protection of transmitted data from interception.

⚠️ Note: The settings interface may vary slightly depending on your Windows build version (Home, Pro, Enterprise). If you don't see the "Mobile" option, check for system updates.

After saving the settings, simply toggle the "Allow network sharing" switch to "On." The system will automatically start the sharing service, and your ASUS laptop will become visible to other devices.

Creating a network via the command line (CMD)

For users who prefer full control over the system, or in cases where the graphical interface is not working correctly, the command line method is ideal. This method allows you to set more specific parameters, such as network type and SSID hiding.

Launch the Command Prompt with administrator privileges. Enter the command to create the virtual adapter: netsh wlan set hostednetwork mode=allow ssid=MyAsusNet key=MyPassword123. Here MyAsusNet — this is the name of your network, and MyPassword123 — access key.

Once the network has been successfully created, it needs to be activated. To do this, enter the command netsh wlan start hostednetworkIf the system displays a message indicating successful startup, the virtual adapter has been created and is ready to use.

However, the setup doesn't end there. You need to allow other devices to use your internet connection. Open Control Panel -> Network and Internet -> Network and Sharing Center.

What to do if the command fails?

If you receive an error when entering commands, make sure the WLAN AutoConfig service is running. Press Win+R, enter services.msc, find the service in the list, and click Start.

In the left pane of the window, select "Change adapter settings." Find your primary adapter (the one that connects to the internet), right-click it, and select "Properties." Go to the "Sharing" tab and check the box next to "Allow other network users to connect through your internet connection."

In the drop-down list below, select the newly created virtual adapter (usually named "Wireless Network Connection" with a number). Click OK to save the settings.

Solving common connection problems

Despite the simplicity of the procedure, users may encounter a number of difficulties. Most often, the issue lies with drivers or power-saving settings. If the phone detects the network but won't connect, try updating the ASUS wireless module drivers.

Another common cause of crashes is Windows' aggressive power saving policy. The operating system may automatically disable the adapter to conserve battery power, resulting in disconnections with connected clients.

To disable power saving, go to Device Manager, find your Wi-Fi adapter, open its properties, and on the Power Management tab, uncheck the box next to Allow the computer to turn off this device to save power.

It's also worth checking your firewall settings. Sometimes antivirus software or a built-in firewall can block incoming connections, considering them potentially dangerous. Add your newly created network to the list of trusted ones.

Setting up security and restricting access

The security of the hotspot you create is a top priority. An open network allows anyone within range to connect to your laptop and potentially access your personal files or traffic.

Use an encryption protocol WPA2-PSK or WPA3, if your hardware supports the latest standard. The password should be complex and contain mixed-case letters, numbers, and special characters. Avoid using simple combinations like "12345678."

You can hide the network name (SSID) in the command line so it doesn't appear in the list of available connections on guest phones. To do this, add the hide option when creating the network, although this option may not be available in the standard Windows interface without third-party tools.

Regularly check the list of connected devices. The hotspot properties in Windows 10/11 display the number of active clients. If you see an unknown device, change the access password immediately.

Avoid transmitting sensitive data, such as banking app passwords, over the created network unless you are confident in the security of your devices. Although traffic is encrypted, the risk of man-in-the-middle attacks is always higher when using improvised access points.

Optimizing signal speed and stability

The internet speed of an ASUS laptop depends on several factors: the power of the wireless module, the airwaves, and the connection type. Laptops' built-in antennas are usually weaker than those of full-fledged routers.

For maximum speed, try placing your laptop in an open area, away from metal objects and microwave ovens, which generate strong interference in the 2.4 GHz band. The optimal height is about 1 meter above the floor.

If your laptop supports dual-band mode, try switching to 5 GHz. This band is less congested with neighboring routers and provides higher throughput, which is critical for streaming videos or making video calls.

Close background applications on your laptop that may consume bandwidth (torrents, game updates, cloud syncing). This will free up bandwidth for connected mobile devices and reduce ping.

Frequently Asked Questions (FAQ)

Is it possible to distribute Wi-Fi if the laptop is connected to Wi-Fi?

Yes, modern network cards from ASUS and other manufacturers support simultaneous operation in both client and access point modes. However, speeds may be lower than with a wired connection, as the channel is split into receive and transmit modes.

How many devices can be connected to a laptop at the same time?

Officially, Windows supports up to 8 simultaneous connections in mobile hotspot mode. In practice, stable operation is observed with 3-5 active devices, after which speed drops and latency increases.

Does the distribution mode affect the wear and tear of a laptop?

Intensive Wi-Fi operation leads to increased heat generation. When running for long periods in a hot room, this can cause processor throttling (reduced performance). Monitor the case temperature.

Why does the internet disappear on my phone after connecting?

The problem is most likely with your DNS settings or a lack of access to the gateway. Try manually entering the DNS in your phone's Wi-Fi settings (e.g., 8.8.8.8) or re-creating the access point on your laptop.
