A situation where a smartphone successfully receives data from a cellular operator, but The computer does not connect to the Internet via the phone's Wi-Fi., is one of the most common problems in mobile offices. The user sees the network, enters the password, but the connection icon remains "Limited" or "No Internet Access." This is frustrating, especially if work is stalled and there are no alternative communication channels available. There can be many reasons for this behavior, ranging from a simple glitch in Windows network settings to incompatibility of frequency bands between the laptop adapter and the smartphone module.
Often the problem lies not in the phone itself that is transmitting the signal, but in how the desktop operating system handles the incoming connection. Windows or macOS Connections may be blocked for security reasons or due to IP address conflicts. It's also worth considering that modern smartphones use advanced encryption protocols and frequencies that older PC network cards may simply not support. Understanding how an access point works helps you quickly isolate the problem and fix it without reinstalling drivers.
In this article, we'll take a detailed look at all possible connection failure scenarios. We'll cover modem settings on Android and iOS, check TCP/IP settings on your computer, and examine rare but possible antivirus software conflicts. Diagnostics The process should be step-by-step: first, simple input errors are eliminated, then hardware compatibility is checked, and only then do they move on to complex manipulations with the registry and system services.
Basic diagnostics and connection status
The first step should always be a visual and logical check of the condition of both devices. If The computer doesn't see the Wi-Fi network. If your phone isn't working at all, the problem is most likely related to the smartphone or physical distance. Make sure the Hotspot feature is enabled and not in sleep mode. Many modern phones automatically disable hotspotting if no one connects for 1-5 minutes to conserve battery life.
If the network is visible but you can't connect, check the number of connected clients. Your phone's hotspot settings often limit the number of devices (usually 5 or 8 by default). If this limit is reached, a new computer won't be able to obtain an IP address. Also, check if "Whitelist" mode is enabled, which blocks all new connections, even with the correct password.
⚠️ Note: If you're using a corporate laptop, your administrators may have blocked the ability to create or connect to mobile hotspots through group policies. In this case, no settings at your level will help.
It's important to check that the internet connection is working on your phone when you're sharing data. Open your smartphone's browser and try loading any page. If your mobile data isn't working, then sharing won't work. Carriers may block data sharing (TTL filters) or require a special service, especially on unlimited plans.
Compatibility issues between Wi-Fi bands and standards
One of the most technical and often ignored reasons is the incompatibility of frequency bands. Modern flagship smartphones create an access point in the frequency band by default. 5 GHz to ensure high data transfer rates. However, many older laptops and budget USB adapters only support the 2.4 GHz band. As a result, the computer simply "doesn't see" the network or can't connect to it due to differences in standards.
To resolve this issue, you need to go to your smartphone's hotspot settings. Under "Access Point Setup" or "Wi-Fi Configuration," find the "Band" setting. Switch it from "5 GHz" or "Preferred" to "2.4 GHz." This will reduce the maximum speed, but significantly improve compatibility and signal range, which is critical for older network cards.
It's also worth paying attention to the security standard. If the phone has a protocol installed WPA3, and the computer's network card is old and only supports WPA2, the connection will fail. Some Android manufacturers allow you to select a specific protocol version manually, others do this automatically when downgrading, but sometimes explicit user intervention is required.
Why is 5 GHz worse at penetrating walls?
The 5 GHz band has a shorter wavelength, which provides high speeds, but is significantly less effective at penetrating solid obstacles. If there's a wall or metal case between your phone and your PC, the signal may be too weak for a stable connection.
IP and DNS settings on your computer
If a physical connection is established but the internet isn't working, the problem often lies in the static network settings on your computer. You may have previously specified a static IP address for my home network, and now these settings conflict with the range of addresses assigned by the phone. The phone acts as a DHCP server and tries to assign its address, but the computer stubbornly insists on its old settings.
To fix the situation, you need to go to the properties of the network adapter. In Windows, this is done via Control Panel → Network and Internet → Network and Sharing Center → Change adapter settingsFind your wireless connection, right-click it, and select Properties. Find the protocol in the list. Internet Protocol version 4 (TCP/IPv4) and make sure that the "Obtain an IP address automatically" and "Obtain DNS server address automatically" boxes are checked.
Manually resetting DNS often helps, as mobile network providers may use their own gateways that don't support static DNS from Google or Yandex. Try manually entering DNS if automatic mode doesn't work. For example, use addresses 8.8.8.8 or 1.1.1.1This can bypass domain name resolution issues where websites don't load even though Skype or Telegram works.
☑️ Check network settings
Driver and Windows service conflicts
Unstable operation of wireless module drivers is a classic reason why The computer does not connect to the Internet via the phone's Wi-Fi.The driver may be corrupted, outdated, or, conversely, too new and contain errors. This is especially common when Wi-Fi stops working after a Windows update. The system may have replaced the working driver with a generic one that incorrectly handles the handshake with the mobile hotspot.
Try removing the device from the Device Manager. Click Win + X, select "Device Manager," find the "Network Adapters" section, right-click your Wi-Fi module, and select "Uninstall device." Then, restart your computer. The system will automatically attempt to reinstall the driver, which often resolves software conflicts.
It's also worth checking the WLAN AutoConfig service. If it's disabled or stopped, connecting to wireless networks will be impossible. Open a command prompt as administrator and enter the command services.mscFind the service in the list. WLAN AutoConfig, make sure the startup type is set to Automatic, and click the Start button if the service is stopped.
⚠️ Important: Before uninstalling drivers, make sure you have access to a wired internet connection or have downloaded the driver installer in advance so that if the automatic Windows installation fails, you can install it manually.
Restrictions from the mobile operator
It's worth remembering that mobile operators are actively combating unlimited data sharing. If you have a plan marked "unlimited," the operator may see that you're not using the SIM card in your phone, but sharing data on your PC. This is determined by the parameter TTL (Time To Live). On mobile devices, it's usually 64, while on computers, it's 128 or 255. When the TTL jumps, the operator either blocks the connection or starts charging a separate rate.
In this case, the computer may connect to the phone's Wi-Fi, but pages won't load, or you'll see a placeholder page from the operator asking you to enable the service. You can work around this by changing the TTL on the computer to 65 (since it will decrease by 1 when passing through the phone, becoming 64). This can be done via the Windows registry or the command line.
To change the TTL in Windows, open a command prompt as administrator and enter the command: netsh interface ipv4 set global defaultcurhoplimit=65After this, you need to restart your computer. On Android, changing the TTL often requires root access or special apps, but on a PC, this may be enough to restore access.
Specifics of configuring APN and network modes
Access point name (APN) settings affect not only how the internet works on the phone itself, but also how the internet is broadcast. If "3G Only" or "2G/3G" is selected in the mobile network settings, speeds will be low, and modern websites may not load, creating the illusion of a disconnected connection. Make sure "3G Only" or "2G/3G" is enabled in the mobile network settings. 4G/LTE or 5G.
Sometimes creating a new APN from scratch helps. Go to your mobile network settings, find your current access point, and copy its settings to the new one, naming it something like "Internet Fix." In some cases, carriers change their APN field requirements, and manually creating a profile with the latest data (which can be found on the carrier's website) resolves the issue.
Below is a table with APN settings for the major operators that you may need to check:
| Operator | Access Point Name (APN) | Authentication type | APN type |
|---|---|---|---|
| MTS | internet.mts.ru | PAP | default,supl |
| Beeline | internet.beeline.ru | PAP/CHAP | default |
| Megaphone | internet | No | default,supl |
| Tele2 | internet.tele2.ru | PAP | default |
⚠️ Please note: APN settings may vary depending on your region and specific tariff plan. Always check the latest settings in your operator's account or on the official support website.
The impact of antiviruses and firewalls
Third-party antivirus suites (Kaspersky, ESET, Avast, etc.) often have built-in network protection modules. They may classify the new "Android Hotspot" network as "Public" and block incoming and outgoing connections for security purposes. If you've just connected and the antivirus asks you about the network type, and you select "Public," access may be restricted.
Try temporarily disabling your antivirus firewall and checking your internet connection. If the issue is resolved, you'll need to add your home network to the trusted list or create an exception for internet tethering. The built-in Windows firewall can also block the connection if the network profile is incorrectly defined.
To change your network profile in Windows 10/11, click the Wi-Fi icon, select "Properties" for your network, and switch the profile from "Public" to "Private." This will allow your computer to be visible on the network and exchange data without strict firewall restrictions.
Why does my computer say "Can't connect to this network"?
This error usually means the password is saved incorrectly or the security settings (encryption) don't match. Try "Forget Network" on your computer and re-enter the password. Also, check if your phone has MAC address restrictions.
Is it possible to share Wi-Fi if the phone has a screen password?
Yes, you can. Locking the screen doesn't affect the hotspot if it's already activated. However, some phones may turn off Wi-Fi to save power when the screen goes dark. You'll need to enable background Wi-Fi in the battery settings.
Why is the Wi-Fi speed from my phone lower than on the smartphone itself?
Speed is reduced by double signal conversion (radio-to-radio), phone transmitter power limitations, and potential interference. Furthermore, if the computer is connected to 2.4 GHz and the phone is using 4G/5G, the Wi-Fi channel will become the bottleneck.
How do I know how many devices are connected to my hotspot?
Most Android smartphones display a list of connected users in the "Access Point" menu. You can also see their IP addresses and block access to a specific device if necessary.
