Why isn't my computer's Wi-Fi working on my phone? Troubleshooting

It often catches you by surprise when a laptop or desktop PC with a wired internet connection refuses to broadcast to mobile devices. You may have everything set up, but your phone simply doesn't see the network or says the connection is impossible. This is a common issue in Windows 10 and 11, and is rarely related to hardware failure.

Most often, the root of the problem lies in software conflicts, outdated drivers, or blocking by antivirus software. Mobile hotspot — the function responsible for broadcasting is extremely sensitive to power saving settings and frequency bands. Understanding how the operating system manages network adapters will help you quickly identify the cause of the problem.

In this article, we'll detail all possible scenarios for internet connection failure. We'll cover everything from simple service status checks to complex registry and command line manipulations to restore your stable connection.

Basic diagnostics and service status

The first thing to do before delving into the settings is to ensure the feature itself is properly enabled. In modern versions of Windows, this mechanism is called "Mobile Hotspot." If the switch is grayed out or the system reports "Unable to set up Mobile Hotspot," it's being blocked at the system service level.

The key element here is service SharedAccessThis service is responsible for providing internet access to other devices. If this service is disabled or is not working properly, no interface settings will help. Check its status using the standard service management utility.

⚠️ Attention: Third-party antivirus programs (Kaspersky, ESET, Avast) often block the creation of a virtual adapter, considering it suspicious activity. Try temporarily disabling network protection in your antivirus to test this hypothesis.

It's also worth paying attention to the internet connection type on your computer. If you're connected through a corporate network or your ISP uses specific authentication (for example, via a web page), sharing may be prohibited by security policies. Such restrictions are less common at home, but ISPs sometimes block it. traffic distribution on several devices within one tariff.

For a quick check, follow these steps:

  • 📶 Open Settings → Network & Internet → Mobile Hotspot.
  • 🛠 Click "Edit" and make sure the correct source connection is selected.
  • 🔄 Try switching the frequency range from 5 GHz to 2.4 GHz if your phone is old.

Problems with network adapter drivers

One of the most common reasons why a computer doesn't distribute Wi-Fi is incorrect driver functionality. The virtual adapter created by the system for distribution (usually called Microsoft Wi-Fi Direct Virtual Adapter) may conflict with your network card's physical driver. This often happens after a major Windows update or a power surge.

In Device Manager, check the status of your network adapters. If you see a yellow exclamation point next to a wireless device, the driver is faulty. In this case, a complete software reinstallation from the laptop or motherboard manufacturer's website, rather than through Windows Update, can help.

Sometimes the problem can be solved by simply changing the power management settings. The system may "sleep" the adapter to save power, which interrupts the sharing process. Go to the adapter properties, find the "Power Management" tab, and uncheck "Allow the computer to turn off this device to save power."

☑️ Driver diagnostics

Completed: 0 / 4

It is also important to check if your physical adapter supports the mode Hosted NetworkSome older cards or specific enterprise drivers may not support this feature. You can use the command line to check, but we'll discuss that in the CMD section.

Frequency range settings and compatibility

Modern routers and laptops often operate in two bands: 2.4 GHz and 5 GHz. The 5 GHz standard provides high speeds, but has a shorter range and is less effective at penetrating walls. Furthermore, many older smartphones simply cannot detect networks broadcasting in the 5 GHz band.

If your phone can't detect the network created by your computer, try forcing the hotspot band to 2.4 GHz. In Windows 10 and 11, this can be done in the hotspot settings menu. However, if the band selection option is grayed out, it means the driver or hardware doesn't allow manual control of this setting.

In this case, changing the regional settings of your wireless network may help. Sometimes, changing the region in the adapter's properties unlocks hidden features. But be careful: selecting the wrong region can lead to violations of radio frequency laws, although this is rarely checked in home settings.

Parameter 2.4 GHz 5 GHz Impact on distribution
Range of action High (up to 50 m) Medium (up to 20 m) At 5 GHz, the phone may lose signal in the next room.
Compatibility 100% of devices Only modern gadgets Older phones will not see the 5 GHz network.
Speed Up to 150-300 Mbps Up to 800+ Mbps For gaming and 4K video, 5 GHz is better.
Noise immunity Low (many neighbors) High In apartment buildings, 2.4 GHz is often clogged.

It's also worth mentioning that some network cards can't simultaneously receive and broadcast Wi-Fi. If your PC is connected to the internet via Wi-Fi, it may refuse to broadcast the network further due to hardware limitations. In this case, only USB adapter or connecting an Ethernet cable.

Why isn't 5GHz always better?

While the 802.11ac/ax standard (5 GHz) offers incredible speeds, its signal penetration through concrete walls is significantly weaker. If you're sharing internet from a laptop in one room and using your phone in another, good old 2.4 GHz will be more stable.

IP address conflicts and network resets

Sometimes the problem lies in the computer's inability to assign the correct IP address to the connecting phone. The DHCP service, built into Windows's IP address distribution mechanism, can malfunction, especially if static IP addresses were previously used or the network environment has changed.

The most effective way to resolve this is to perform a full reset of network settings. This will return all network components (including virtual Bluetooth and VPN adapters) to their factory defaults. After rebooting, the system will reinstall the drivers and recreate the address pool.

To perform a reset:

  • 🚀 Open Settings → Network & Internet → Advanced network settings.
  • 🗑 Find the "Network Reset" button and press it.
  • 📵 Confirm the action and wait for the computer to restart (usually after 5 minutes).

If the automatic reset doesn't help, you can try manually updating the IP configuration via the command line. Open the terminal as administrator and enter the command ipconfig /release, and then ipconfig /renewThis will force the computer to re-request the address from the ISP or router, which may resolve the conflict.

⚠️ Attention: After resetting your network, you'll need to re-enter passwords for all previously connected Wi-Fi networks. The system will delete any saved profiles.

Using the command line to create an access point

When the Windows graphical interface crashes, the command line (CMD) comes to the rescue. This powerful tool allows you to create a network without using the standard "Mobile Hotspot" menu. This is especially useful if the power button in Settings simply won't click.

First, you need to check whether your adapter supports hosted network mode. Enter the command netsh wlan show drivers and find the line "Hosted network support." If it says "No," you won't be able to launch the access point programmatically without replacing the driver or adapter.

If there is support, we create a network using the command:

netsh wlan set hostednetwork mode=allow ssid=MyNetwork key=MyPassword123

Here MyNetwork — the name of your network, and MyPassword123 — password (minimum 8 characters). After this, the network must be started with the command netsh wlan start hostednetworkIf everything went well, a new hotspot will appear in the list of available networks on your phone.

However, simply creating a network isn't enough—you need to share the internet. To do this:

  • 💻 Open Control Panel → Network and Internet → Network and Sharing Center.
  • 🔗 On the left, select "Change adapter settings".
  • 📡 Find your main adapter (the one that connects to the Internet), right-click → “Properties”.
  • 📤 Go to the "Access" tab and check the "Allow other users..." box, selecting the created virtual adapter from the list.

Alternative distribution methods and third-party software

If Windows' built-in tools absolutely refuse to work, there are third-party programs that take control of network adapters. They often ignore system errors and force broadcasting.

Popular utilities like Connectify Hotspot or MyPublicWiFi have more flexible settings. They allow you not only to distribute Wi-Fi, but also to monitor connected users, limit speeds, and even block ads for all devices on the network.

Another often-overlooked option is sharing via Bluetooth or a USB cable. While Bluetooth speeds will be slow, it's sufficient for text messaging or using instant messaging apps in an emergency. USB modem (Reverse Tethering) is also possible, but requires installing ADB drivers or special utilities from the phone manufacturer.

If the standard Windows mechanism does not work, it means there is a deep conflict in the system, which is better to resolve than to keep a “heavy” program running constantly.

Frequently Asked Questions (FAQ)

Why does my phone connect to Wi-Fi from my computer, but there is no internet?

The issue is most likely related to the sharing settings. Check that "Allow other network users to connect through my Internet connection" is checked in the primary adapter properties. Also, make sure that the IPv4 properties of the primary adapter are set to obtain an IP address automatically.

Is it possible to distribute Wi-Fi if the computer is connected to the Internet via Wi-Fi?

Technically, this is possible, but most standard network cards can't simultaneously receive and transmit Wi-Fi signals on different frequencies. Speed ​​will be very low, or the connection will be constantly dropping. It's better to use a USB modem or an Ethernet cable.

How do I know how many devices are connected to my hotspot?

In the standard Windows 10/11 interface, the "Mobile Hotspot" section displays the number of connected devices. For more detailed information (IP addresses, MAC addresses), you can use third-party utilities or the command arp -a in the command line, although it shows all devices on the local network.

Does the hotspot password reset after reboot?

No, your mobile hotspot settings, including the network name (SSID) and password, are saved in the system. However, if you reset your network settings completely, you'll need to recreate the profile.
