How to share internet from an ASUS laptop to a phone via WiFi

In today's digital world, access to the global internet often becomes a critical resource, essential for work, study, or emergency communications. Situations where a home provider is unavailable and mobile 3G/4G signal is extremely weak are common. It's in these situations that turning your laptop into a fully-fledged hotspot comes in handy.

Equipment owners ASUS People often wonder how to effectively use an existing wired connection or a weak mobile modem to ensure a stable signal for their smartphone. Modern operating systems, such as Windows 10 And Windows 11, have built-in tools that allow you to organize signal broadcasting without installing complex third-party software.

This article will detail the setup process, potential issues, and nuances you might encounter when setting up a local wireless network. You'll learn how to properly configure security and power-saving settings to prevent your laptop from disconnecting the access point at the most inopportune moment.

Checking hardware compatibility and drivers

Before you begin software configuration, you need to make sure that hardware Your ASUS laptop is ready to work in access point mode. Most modern models released in the last 7-8 years are equipped with wireless adapters that support the standards 802.11ac And 802.11ax, which guarantees high data transfer speed.

The key is to have up-to-date drivers. If the drivers are outdated or the default Microsoft plug-ins are installed, the sharing function may be unstable or even absent. You can check the driver status in Device Manager by finding the "Network Adapters" section.

Please pay attention to the name of your adapter. If it contains the words Wireless, WiFi or 802.11, which means the device is theoretically capable of transmitting a signal. In rare cases, older ASUS models may require manual software download from the manufacturer's official website.

⚠️ Attention: If a yellow exclamation point appears next to your network adapter in Device Manager, this indicates a driver conflict. In this case, creating an access point will be impossible until the error is resolved.

Setting up a hotspot in Windows 10 and 11

Windows operating systems offer a native tool called "Mobile Hotspot." This functionality completely replaces the need for the command line or third-party programs like ConnectifyTo get started, simply go to the system settings via the Start menu.

In the window that opens, select the "Network and Internet" section, then find the "Mobile Hotspot" tab. Here, the user is asked to select the connection source that will be shared. This can be either Ethernet (cable internet), as well as a signal from another WiFi adapter, if the laptop is connected to one network and broadcasts another.

Next, click the "Change" button to set the network name (SSID) and password. We recommend using a complex password containing letters and numbers to prevent unauthorized access to your traffic. After saving your settings, simply toggle the switch to the "On" position.

It's worth noting that the interface has been slightly modified in Windows 11, but the logic remains the same. The system will automatically select the optimal frequency range, but you can change it in the adapter properties if necessary.

Using the Command Prompt for Advanced Users

For those who prefer full control over the system or encounter graphical interface errors, there's an alternative method via the console. The command line allows you to create a virtual adapter with specified parameters, which can sometimes help bypass software blockages.

To launch the console, right-click the Start menu and select Windows PowerShell (Admin) or Command Prompt (Admin). The first step is to check if your ASUS adapter supports the host network.

netsh wlan show drivers

In the command output, look for the line "Hosted network support." If it says "Yes," you can proceed to create the network. Enter the command to create the network, replacing MyNetwork to the desired name, and MyPassword for a complex password:

netsh wlan set hostednetwork mode=allow ssid=MyNetwork key=MyPassword

After successful creation, you need to start the network with the command netsh wlan start hostednetworkHowever, for the internet to actually work, there's one more important step: sharing the connection.

How to share the Internet via network connections

Open Control Panel -> Network and Internet -> Network and Sharing Center -> Change adapter settings. Find your primary internet adapter, right-click it -> Properties -> Sharing tab. Check "Allow other users to connect to this network..." and select the virtual network you created from the list (usually called Wireless Network Connection 2 or 3).

Distribution Methods Comparison Table

The method you choose depends on your goals and technical expertise. Below is a comparison table to help you decide which method to use to activate a hotspot on your ASUS laptop.

As the table shows, for most users, the built-in interface is the optimal choice. It strikes a balance between simplicity and functionality without requiring in-depth knowledge of network protocols.

Using third-party programs is only justified if standard Windows tools do not work correctly or if specific functions are required, such as limiting traffic for each connected device or detailed statistics.

Setting up frequency range and security

One common issue is network invisibility on older smartphones or, conversely, low speed on newer devices. This is due to the frequency range. Modern ASUS laptops often support these frequency ranges. 2.4 GHz And 5 GHz.

The 2.4 GHz band has a longer range and penetrates walls, but it's more congested with neighboring routers and appliances. The 5 GHz band offers high speed and stability, but its range is significantly shorter.

You can select your preferred band in the mobile hotspot settings (under "Hardware Properties"). If your phone can't see the network, try switching to 2.4 GHz. If the speed isn't working and you're near your laptop, choose 5 GHz.

⚠️ Attention: Not all network cards support dual-band operation. Switching to 5 GHz may result in a loss of connection with your current router if it only operates on 2.4 GHz.

It is also important to pay attention to the security protocol. Always choose WPA2-Personal or WPA3, if your equipment allows it. Using an open network or the outdated WEP protocol makes your data vulnerable to interception by hackers.

Solution and troubleshooting

Even with proper setup, situations may arise where the phone connects to WiFi but the internet is unavailable ("No internet access"). This is often due to DNS settings or IP address conflicts.

First, try renewing your IP address. Open Command Prompt as administrator and enter the command ipconfig /release, and then ipconfig /renewThis will force the laptop to request new network settings from the ISP.

Another common cause is power saving settings. ASUS laptops are known for their aggressive power optimization, which can disable the WiFi adapter to save battery life. To fix this, go to "Device Manager," find your wireless adapter, open its properties, and in the "Power Management" tab, uncheck "Allow the computer to turn off this device to save power."

• 🔄 Network reset: In Windows settings, look for the "Network reset" button, which will reinstall all network drivers and return the settings to factory defaults.
• 🛡️ Antivirus: Temporarily disable any third-party antivirus or firewall software, as they may be blocking incoming connections to the virtual adapter.
• 💾 Drivers: Try rolling back your WiFi driver to a previous version if the problem appeared after a system update.

Optimizing laptop power consumption

Sharing Wi-Fi is a power-hungry process. The wireless module operates in constant transmission mode, which significantly drains the ASUS laptop's battery. If you're using battery power, battery life can be cut in half.

To extend battery life, we recommend reducing screen brightness, disabling background apps, and, if possible, using Windows' Power Saver mode. However, please note that this may reduce data transfer speeds.

If your laptop is used as a stationary access point, it's best to keep it plugged in. Also, make sure the ventilation holes aren't blocked, as active WiFi can cause additional heat buildup in the keyboard area.

⚠️ Attention: Operating system interfaces and drivers are subject to update. If you don't see the menus described, check the official Microsoft documentation or the ASUS support website for the latest settings for your model.
