The situation when your laptop Refusal to see or connect to an access point created on a smartphone may occur suddenly. Most often, the problem lies not in hardware failure, but in incompatibility of encryption protocols or failure of adapter drivers. When figuring out why the laptop does not connect to wifi from the phone, it is important to take into account many factors: from the operating system version to the frequency range settings.

Many users are faced with the fact that their mobile device successfully distributes the Internet, but the computer displays the error “Could not connect” or simply does not display the network in the list of available ones. This does not mean that you need to buy new equipment or take it to a service center. In most cases, it is enough to make adjustments to Network and Internet settings or update the software.

In this article, we will analyze in detail the main causes of failures and provide step-by-step action algorithms. We will look at situations where the problem occurs on devices with Windows 10, Windows 11, as well as on laptops with macOS. The main thing is not to panic and consistently eliminate possible faults.

Checking the access point and frequency range settings

The first step in diagnosing a problem is to check the parameters set on the smartphone itself. Modern phones allow you to distribute the Internet in two main bands: 2.4 GHz and 5 GHz. Older or lower-end laptop models may not support the 5GHz frequency, which means they won't physically see the network created by a modern phone.

If you are using the model iPhone 12 or newer or flagship Samsung Galaxy, by default the high-frequency distribution mode may be enabled. You need to go into the mobile hotspot settings and force the band to change to 2.4 GHz. This is a universal solution that helps in 80% of cases when the laptop simply does not see the network.

  • 📱 Go to Settings → Hotspot and tethering on a smartphone
  • 📡 Find “AP Band” or “Frequency”
  • 🔄 Switch the value to 2.4 GHz

It is also worth paying attention to the way the network is protected. Some older adapters cannot work correctly with the WPA3 protocols that are being implemented in the latest smartphones. If the laptop is outdated, try changing the encryption to WPA2-PSK, if such an option is available in the distribution menu.

⚠️ Attention: If you use tariffs with unlimited Internet, operators may block distribution. Make sure that your tariff plan allows you to create an access point without restrictions.

Sometimes the problem lies in the network name (SSID). If the access point name contains Cyrillic characters or special characters, some network card drivers may interpret them incorrectly. Try renaming the network using only Latin letters and numbers.

Clear DNS cache and reset network settings

If the access point settings are correct, but the connection is still not established, the problem may be in the software of the laptop itself. The DNS cache often accumulates outdated information about routers, which prevents a new connection from being established. Clearing this cache is a quick and safe way to fix the situation.

To complete the procedure, you will need to open a command prompt with administrator rights. Enter the commands in sequence to reset the network components. This action will not delete your personal files, but it will temporarily disable your network adapters.

ipconfig /flushdns

netsh winsock reset


netsh int ip reset

After entering the commands, you must restart your computer. It is important to note that on laptops HP or Dell After rebooting, the system may ask you to reconnect to Wi-Fi, as all saved passwords will be reset. Be prepared to enter your phone's hotspot password again.

  • 🔍 Click Win + X and select Windows PowerShell (Administrator)
  • 💻 Enter reset commands one by one
  • 🔌 Restart your laptop and try connecting again

☑️ Reset network settings

Done: 0 / 4

Also in the settings of Windows 10 and 11 there is a function to completely reset the network, which removes all network adapters and reinstalls them with factory settings. This is a more radical method, but it is effective if standard cache clearing does not help. It is located in the section Settings → Network and Internet → Network reset.

⚠️ Attention: When using the Network Reset function, you will have to re-enter passwords for all known Wi-Fi networks, including your home router.

Managing network adapter drivers

One of the most common reasons why a laptop does not connect to wifi from a phone is incorrect drivers. A driver is a program that controls a physical device, and if it is out of date or damaged, the adapter may become unstable. This is especially true after major operating system updates.

To check the driver status, open Device Manager. Find the Network Adapters section and look at your wireless device. If there is a yellow exclamation mark or a down arrow next to it, then the driver is not working or is disabled. In this case, it needs to be updated or reinstalled.

Sometimes the system itself offers to update the driver via the Internet, but this is not always effective if the problem is a lack of access. It is better to download the current version of the driver from the official website of the laptop manufacturer using another computer or phone (via a USB cable).

  • 🛠️ Open Device Manager via Windows search
  • 📡 Find an adapter, e.g. Intel Wi-Fi 6 AX200 or Realtek RTL8822CE
  • ⬇️ Right click and select Update driver

If the update doesn't help, try removing the device from the list and then restarting the laptop. The system will automatically detect the hardware and install a standard driver, which often works more stable than custom versions.

What to do if the driver is not found?

If the automatic search does not produce results, go to the laptop manufacturer's website (for example, ASUS, Lenovo, Acer), find your model in the support section and download the Wireless LAN driver manually.

💡

Outdated adapter drivers are the most common cause of incompatibility with new security protocols used by smartphones.

IP Address Conflict and DHCP Check

Sometimes the laptop sees the network, but when trying to connect, it freezes at the “Obtaining an IP address” stage. This suggests that the DHCP protocol, which automatically issues addresses to devices, cannot distribute the address correctly. The phone can produce addresses in one range, but the laptop is “stuck” on the old value.

To fix this, you need to manually set a static IP address or force a configuration update. To do this, go to the connection properties and change the settings for IP protocol version 4 (TCP/IPv4). Specify an address that does not overlap with the addresses of other devices on the network.

Typically, a phone in access point mode uses the 192.168.43.x or 192.168.1.x range. Make sure you enter the correct address, gateway and DNS. Incorrect configuration will result in complete loss of communication.

Parameter Meaning (example) Comment
IP address 192.168.43.150 Last digit from 2 to 254
Subnet mask 255.255.255.0 Standard mask
Main gateway 192.168.43.1 Phone IP address
DNS server 8.8.8.8 Google DNS

If you don't want to configure a static IP, you can try disabling and enabling the adapter on the system. This will cause it to re-request the address from the phone. Also check if the Power Saver mode is enabled for the network adapter in Device Manager, as this may be blocking the address from being received.

Features of working on macOS and Linux

Laptop users MacBook face similar problems, but the solutions are slightly different. In macOS, network settings are hidden deeper, and sometimes the system aggressively caches old configurations. If your Apple laptop does not connect to the access point, you should check the “Reset Wireless Module” settings.

To do this, you can enter special commands in the terminal that restart Wi-Fi service processes. It is also important to check if the "Random MAC Address" mode is enabled in your privacy settings, as some phones block devices with such addresses.

  • 🍏 Go to System Settings → Network
  • 🔄 Click the Actions button and select Reset Wi-Fi Settings
  • 📶 Remove the old network from the “Known Networks” list

On Linux systems, the problem is often solved through the terminal, where you can forcefully restart the NetworkManager service. Team sudo systemctl restart NetworkManager often restores functionality to the adapter without having to reboot the entire system.

⚠️ Warning: On Apple devices, make sure you are not using Hidden Network mode on your phone, as macOS may not correctly handle connecting to hidden SSIDs without manual configuration.
💡

Before resetting your Mac, make sure you know your Wi-Fi password, as the system will remove it from the key store.

Impact of Antivirus and Firewall

Sometimes the problem lies not in the network settings, but in the security software. Antiviruses such as Kaspersky, ESET or built-in Windows Defender, can block incoming connections from new devices, considering them a potential threat. This is especially true if you are connecting to an access point for the first time.

Temporarily disable your antivirus and firewall to check if your laptop will connect to the Internet. If the problem goes away, you need to add your phone's access point to the list of trusted networks in your security software settings. Don't forget to turn the protection back on after the test.

It’s also worth checking your “Private Network” and “Public Network” settings. If Windows has defined your phone's hotspot as "Public", it may block discovery of the device and access to shared resources, although the Internet may still work. Change the network profile to “Private”.

  • 🛡️ Open your antivirus settings
  • 🚫 Temporarily disable network protection
  • 🔌 Try connecting to an access point

If disabling your antivirus helps, don't leave it turned off. Find in the firewall settings the item responsible for detecting new networks and allow it to connect to them automatically.

💡

The firewall often blocks new connections by default, so checking your security settings is a mandatory diagnostic step.

Hardware faults and airplane mode

In rare cases, the problem may be related to the physical condition of the laptop. Check to see if Airplane Mode is accidentally turned on. In this mode, all wireless modules are disabled, and the laptop will not search for any networks, including the phone's access point.

Some laptops have a hardware button or key combination (usually Fn + F2 or Fn + F12), which physically disables the Wi-Fi module. Make sure the Wi-Fi indicator is on. If it doesn't light up, try pressing this key combination or finding the button on the case.

If all else fails, the adapter may be faulty. This can be checked by connecting an external USB Wi-Fi adapter to the laptop. If the external adapter sees the phone's network, then the problem is in the laptop's built-in module and will need to be replaced or replaced.

How to check if the adapter is working?

Try connecting another Wi-Fi router. If the laptop doesn’t see it either, then the problem is definitely in the laptop itself, and not in the phone.

💡

Some laptops have an "Adaptive Wi-Fi" feature that turns off the module when the battery is low. Connect the laptop to the charger to test.

Frequently asked questions (FAQ)
