Many people are familiar with the situation of urgently needing internet access on their computer but not having a wired connection. You activate the hotspot on your smartphone, but your laptop stubbornly refuses to connect, displaying the error "Can't connect to this network" or simply endlessly trying to find a network. This is a common problem that can be caused by a dozen different factors, from outdated drivers to frequency band conflicts.
In most cases the problem is not a hardware failure, but rather incorrect software settings or security parameters. Modern operating systems, whether Windows 10, 11, or macOS, have their own unique way of working with wireless adapters, which often conflict with the traffic distribution algorithms of Android and iOS. Understanding how a hotspot works will help you quickly diagnose the problem.
Before you move on to complex registry manipulation or system reinstallation, it's worth checking the basics. Sometimes it's enough to simply reboot both devicesto clear temporary network errors. However, if a simple reboot doesn't help, you'll need to tweak your frequency settings, encryption protocols, and power saving settings. In this article, we'll cover all possible causes and troubleshooting methods in detail.
Frequency Band Compatibility Issues: 2.4 GHz vs. 5 GHz
One of the most common reasons why a laptop can't detect the network broadcast by a phone is incompatible frequency bands. Modern smartphones often create an access point in the same frequency band by default. 5 GHz, as it provides higher data transfer speeds and is less congested with neighboring networks. However, many older laptops and some budget models simply don't have a module that supports this standard.
If your computer is more than 5-7 years old, its Wi-Fi adapter likely only operates at 2.4 GHz. In this situation, it will be physically unable to "see" the network broadcast by your phone. Even if the network appears in the list of available networks, connecting will be impossible or will constantly drop due to a weak signal or protocol errors.
⚠️ Note: On some Samsung and Xiaomi models, band settings may reset after a system update. Always check this setting again if your internet connection stops working.
To fix this, you need to force the phone's hotspot to switch to 2.4 GHz mode. This will slightly reduce the maximum speed, but it guarantees compatibility with older devices. On iPhone, this setting is called "Maximum Compatibility," and on Android, it's located in the advanced hotspot settings.
Network adapter driver and configuration errors in Windows
Even if everything is configured correctly on your phone, the problem may lie with the laptop itself. Wi-Fi adapter drivers are software intermediaries that allow the operating system to control the hardware. If the driver is outdated, corrupted, or malfunctioning, the laptop may not properly process connection requests to mobile hotspots.
Users often forget about power saving settings. Windows tries to conserve battery life and may disable the wireless adapter or limit its functionality, making it impossible to maintain a stable connection with the phone. The encryption type or security protocol may also be disabled.
To diagnose the problem, you need to go to the Device Manager. In the search field, enter devmgmt.msc and press Enter. Find the "Network Adapters" section, select your Wi-Fi module (usually the name includes words like "Wireless," "Wi-Fi," or "802.11," or brands like Intel, Realtek, or Qualcomm), and open its properties.
- 📡 Check the device status: the "Device Status" field should say "The device is working properly."
- ⚡ Disable power saving: On the Power Management tab, uncheck the box next to "Allow the computer to turn off this device to save power."
- 🔄 Update the driver: Click "Update driver" and select automatic search, or download the latest version from the laptop manufacturer's website.
If the automatic search doesn't help, try completely uninstalling the device and restarting your computer. The system will attempt to reinstall the driver upon startup. It's also worth checking to see if airplane mode is enabled, which could block the adapter software-based.
Access Point Settings on Android and iOS
Internet tethering settings on mobile devices also have their own nuances. The latest versions of Android and iOS have introduced additional security layers that can hinder connections. For example, using random MAC addresses or strict WPA3 encryption protocols may not be recognized by a laptop's network adapter.
On Apple devices, it's important to pay attention to the "Maximum Compatibility" feature. If it's disabled, the iPhone only broadcasts on the 5 GHz band. Enabling this option switches the network to 2.4 GHz, which solves issues with older laptops. On Android, the situation is more varied due to manufacturer skins (MIUI, OneUI, ColorOS).
It's important to check the access point type. Some Android menus allow you to choose between "Wi-Fi," "USB," and "Bluetooth." Make sure Wi-Fi is activated. It's also worth checking the number of connected devices: if the limit is reached (usually 5-10 devices), the new laptop won't be able to connect.
⚠️ Note: The settings interface may vary depending on your OS version and phone model. If you don't see the "Band" or "AP Band" option, look for it in the "Advanced" or "Access Point Configuration" section.
Another important point is the network name (SSID). If the access point name contains special characters, spaces, or Cyrillic characters, some network cards may not process the network name correctly. Try renaming the access point, using only Latin letters and numbers.
IP address conflicts and resetting network settings
Sometimes the problem is logical: the laptop and phone can't agree on address allocation within the network being created. The phone's DHCP server may refuse to assign an IP address to the laptop, or it may assign an address that's already in the system cache. This results in the "No Internet Access" status or endless identification.
In such cases, the best solution is to reset your network settings. This will return all Windows network settings to factory defaults, clear the DNS cache, reset the TCP/IP stack, and delete saved Wi-Fi profiles that may contain errors.
To reset Windows 10 and 11, open a command prompt as administrator. Right-click the Start button and select "Terminal (Admin)" or "Command Prompt (Admin)." Enter the following commands one by one, pressing Enter after each:
netsh winsock resetnetsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
After running the last command, be sure to restart your laptop. This is a critical step, as changes to the registry and network protocols only take effect after a system restart. If the issue was an address conflict, this should resolve it.

Operator and tariff plan restrictions
It's also important to remember that the internet source is the operator's SIM card. Many mobile operator plans have restrictions on tethering. The operator may block the connection of additional devices or require a separate fee for this feature.
In such cases, the laptop may connect to the phone's Wi-Fi, but the internet won't work. Carriers determine whether the data is being shared based on the TTL (Time To Live) value. When you share the internet, the packet TTL changes, and the carrier sees that the traffic is coming from the computer rather than the phone, and then blocks the connection or charges additional fees.
| Operator | Type of restriction | How does it manifest itself? | Solution |
|---|---|---|---|
| MTS | Paid option or package | Withdraws money, there is internet | Enable the "Sharing" option |
| Beeline | Traffic limitation | The Internet is not working | Check tariff terms |
| Megaphone | Blocking distribution | Payment Request Page | Changing TTL (difficult) |
| Tele2 | GB limit for distribution | Speed drops after the limit | Monitor consumption |
If you suspect your carrier is blocking your data, try opening any website. If you're redirected to a page offering to enable data sharing, the issue is with your data plan. In this case, your laptop and phone settings have nothing to do with it.
⚠️ Please note: Tariff terms and internet tethering rules are constantly changing. Always check your operator's personal account or your mobile operator's app for up-to-date information on using your phone as a modem.
Alternative connection methods: USB and Bluetooth
If you still can't get a Wi-Fi connection, don't despair. There are more stable and faster ways to share internet from your phone to your laptop. The most reliable is connecting via a USB cable. This method not only provides high data transfer speeds comparable to a wired connection but also charges your phone at the same time.
To connect via USB on Android, go to Settings, find the "Tethering & Hotspot" section (or similar), and toggle the "USB Tethering" switch. On iPhone, this feature is called "Personal Hotspot" and requires iTunes installed (for drivers) on Windows. Your computer will recognize the phone as a regular wired network connection.
Why is USB better than Wi-Fi for sharing?
A USB connection is more stable, unaffected by interference, provides lower ping (latency), and doesn't drain your phone's battery while it charges. It's ideal for desktop use.
Bluetooth tethering is another option, albeit the slowest. It's only suitable for transferring small amounts of text data if Wi-Fi is absolutely unavailable and a USB cable is not available. To activate, pair the devices via Bluetooth and enable "Bluetooth tethering" in your phone's Bluetooth settings.
In conclusion, it's worth noting that most connection issues can be resolved by either switching frequency bands or updating drivers. If none of the above methods help, there may be a hardware problem with the Wi-Fi module in your laptop or the antenna in your phone, which will require a service center visit.
Frequently Asked Questions (FAQ)
Why does my laptop see my phone's network, but it says "Unable to connect"?
This most often indicates an incorrect password or an incompatible security protocol. Try changing the password to a simpler one (numbers and letters only) and changing the encryption type in your phone's hotspot settings from WPA3 to WPA2.
Is it possible to share Wi-Fi if the phone is connected to a Wi-Fi router?
Yes, most modern smartphones (Android 10+ and iOS) can act as Wi-Fi repeaters. They receive internet via Wi-Fi and distribute it further, creating their own network. However, the speed may be lower, and the battery will drain faster.
Why did my phone's Wi-Fi stop working after updating Windows?
Windows updates often install new driver versions that may not work correctly. Try rolling back your Wi-Fi adapter driver to a previous version in Device Manager or uninstalling the security update that caused the conflict.
How do I know if my laptop supports 5GHz?
Open command prompt and enter the command netsh wlan show driversFind the line "Supported radio types." If you see 802.11a, 802.11n, or 802.11ac, 5 GHz support is present.
Does the operator charge for internet sharing?
It depends on your plan. Older or unlimited plans often have data sharing limits. Newer bundled plans typically include data sharing at no extra charge, but it's best to check with your carrier.
