Why the laptop does not want to connect to Wi-Fi from the phone: a complete analysis of the reasons and solutions

Have you turned on Internet distribution on your smartphone, but the laptop stubbornly refuses to connect to the created access point? This problem is familiar to many - especially when you urgently need access to the network, but landline Wi-Fi is not available. In 80% of cases, problems with the settings of the phone or laptop are to blame, and not hardware failures. But how to accurately determine the root of the problem and eliminate it without unnecessary movements?

In this article we will look at all possible reasons, through which the laptop does not see the network from the phone or cannot connect to it - from trivial (for example, a forgotten password) to rare (IP address conflicts). You will receive step by step instructions for Windows 10/11, macOS and any smartphones on Android or iOS, and also learn how to diagnose the problem in 2 minutes. Don't waste time on reboots - read on and fix your connection right now.

1. Checking basic settings: 5 steps before deep diagnostics

Before digging into driver or network protocol settings, make sure that the problem is not hidden on the surface. In 60% of cases the problem can be solved in literally 1-2 clicks - if you know where to look.

Start with your phone:

• 📱 Is Internet sharing enabled? On Android check the notification bar or section Settings → Hotspot and tethering. On iPhone — Settings → Modem mode. The indicator should light blue/green.
• 🔒 Is the password correct? Default to Android this is often an 8-digit combination (for example, 12345678), and on iPhone — random set of characters. Make sure you enter it without spaces.
• 📶 Can the network see other devices? Try connecting a friend's phone or tablet to the hotspot. If they also don’t see the network, the problem is with the phone, not the laptop.

Now let's move on to the laptop:

• 💻 Is Wi-Fi turned on? On Windows check the network icon in the tray (bottom right). On macOS — icon in the menu bar. Sometimes the adapter is turned off accidentally by a keyboard shortcut (for example, Fn + F2 on Lenovo or HP).
• 🔄 Are the drivers updated? An outdated Wi-Fi adapter driver may not support modern distribution protocols. More on this in the next section.

Critical moment: if laptop sees the network, but does not connect (writes “Could not connect” or “No Internet access”), the problem lies deeper - most likely in the IP settings or channel conflict. Read about this in sections 3 and 4.

2. Drivers and network adapters: why the laptop does not “see” the network

If the laptop does not display the network from the phone in the list of available ones at all, either Wi-Fi adapter, or its software. Here's how to check it:

On Windows:

1. Click Win + X and select Device Manager.
2. Expand the tab Network adapters.
3. Find a device with words Wireless, Wi-Fi or 802.11 (For example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros QCA61x4).
4. If there is an exclamation mark next to it, the driver is not working correctly. Right click and select Update driver.

On macOS:

• Open About This Mac → System Report → Network → Wi-Fi.
• Check the line Condition. If there's no Connected, and Disabled or Inactive — the adapter is faulty or disabled.

What to do if the driver is updated, but the network is still not visible?

• 🔌 Restart your laptop and phone. It's trivial, but it works in 20% of cases - especially if you previously turned on/off airplane mode.
• 🔧 Reset your network settings. On Windows: Settings → Network and Internet → Status → Network reset. On macOS: delete the file /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist (make a backup copy first!).
• 🛠️ Check BIOS. On some laptops (eg Dell Latitude or HP EliteBook) The Wi-Fi adapter can be disabled at the BIOS level. Go to settings (usually by pressing F2 or Del on boot) and find the section Wireless or Network.

⚠️ Attention: If after updating the driver the laptop stops seeing everything Wi-Fi network (not just from your phone), most likely you installed an incompatible version. Roll back the driver via Device Manager → Adapter Properties → Driver → Roll Back.

3. IP address conflict: why the connection hangs at the stage of obtaining an IP

Situation: the laptop sees the network from the phone, you enter the password, but the connection gets stuck in loops at the "Obtaining an IP address" or "Authentication" stage. Reason: settings conflict DHCP (IP Automatic Assignment Protocol).

Here's how to fix it:

Method 1: Manually assign a static IP (Windows)

1. Open Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings.
2. Right click on Wireless network → Properties.
3. Select IP version 4 (TCP/IPv4) → Properties.
4. Check the box Use the following IP address and enter:

   IP-адрес: 192.168.43.100
   Маска подсети: 255.255.255.0
   Основной шлюз: 192.168.43.1
   DNS: 8.8.8.8 (или 1.1.1.1)

5. Save the settings and try connecting again.

Method 2: Reset DHCP settings on your phone (Android)

• Go to Settings → System → Reset → Reset network settings.
• Reboot your phone and turn on the distribution again.

Method 3. Change the Wi-Fi channel (if the network is visible, but does not connect)

By default, phones distribute Wi-Fi on the channel 6 or 11, which may be overloaded by other networks. Try manually setting a different channel:

• On Android (requires root or ADB):

  adb shell su -c "setprop wifi.softap.channel 3"

  (where 3 — channel number from 1 to 11).

• On iPhone you can’t change the channel - but you can try turning the mode on/off Maximum compatibility in the modem mode settings.

Symptom	Probable Cause	Solution
The network is visible, but the connection freezes	IP or DHCP conflict	Assign a static IP or reset network settings on your phone
The laptop does not see the network, but other devices do	Outdated Wi-Fi driver or disabled adapter	Update driver or check BIOS settings
There is a connection, but no Internet access	Incorrect DNS or gateway settings	Register DNS 8.8.8.8 manually
The network appears and disappears	Noise on the channel or weak signal	Change Wi-Fi channel or reduce the distance between devices

4. Features of operating systems: Windows vs macOS vs Linux

The algorithms for connecting to Wi-Fi differ between operating systems, and this can cause problems. Let's look at the nuances for each system.

Windows 10/11:

• 🪟 "We couldn't connect to this network" - a common error due to the service WLAN AutoConfig. Fixed by restarting:

  net stop wlansvc
  net start wlansvc

  (enter commands in Command line on behalf of the administrator).

• 🔄 Resetting the TCP/IP stack:

  netsh int ip reset
  netsh winsock reset

macOS (Monterey, Ventura, Sonoma):

• 🍎 The laptop does not remember the network. Remove it from your saved list: System settings → Network → Wi-Fi → Advanced → Delete network.
• 🛡️ The firewall is blocking the connection. Temporarily disable it in System Settings → Security and Safety → Firewall.

Linux (Ubuntu, Mint, Fedora):

• 🐧 Error "Activation of network connection failed". Check if the package is installed network-manager:

  sudo apt install network-manager

• 📡 The Wi-Fi adapter is not detected. Install proprietary drivers:

  sudo ubuntu-drivers autoinstall

5. Problems on the phone side: Android and iOS settings

Sometimes the root of all evil lies in the smartphone - especially if the laptop connects normally to other networks. Here's what to check:

On Android:

• 📵 Airplane mode or power saving. Even if they are turned off, some manufacturers (e.g. Xiaomi or Samsung) aggressively limit the background operation of the modem. Go to Settings → Battery → Power saving mode and turn it off.
• 📶 Traffic limitation. At some tariffs, operators block Internet distribution. Check if the option is enabled Modem ban in the SIM card settings.
• 🔄 Reset network settings. How to do this, we wrote in section 3.

On iPhone:

• 🍏 "Modem mode" is inactive. On some operators (for example, Tele2 or Iota) additional activation of the service is required. Call the number *111# and check the status.
• 🔒 MAC address limitation. Go to Settings → Tethering mode → Wi-Fi password and make sure that device filter is not enabled.
• 📱 iOS update. In older versions (below 15.4) there were bugs with Wi-Fi distribution at 5 GHz. Update via Settings → General → Software Update.

What should I do if my phone overheats when using Wi-Fi?

If the phone gets very hot and turns off the distribution, this is normal protection against overheating. To avoid the problem:

1. Close all background applications (especially games and navigators).

2. Remove the cover (it impairs heat dissipation).

3. Connect your phone to charge (Wi-Fi distribution consumes a lot of energy).

4. Reduce screen brightness.

If heating is critical, use a USB modem instead of Wi-Fi.

6. External interference and hardware problems

If all settings are checked, but the laptop still does not connect, the problem may be:

• 📡 Interference from other networks. Use an app like Wi-Fi Analyzer (Android) or NetSpot (macOS/Windows) to check channel traffic. If your channel (for example, 6) is overloaded - change it in your phone settings.
• 🔋 Weak signal. If the phone is at the other end of the room, and the laptop is at the window, the signal may simply not reach. Try bringing the devices closer to each other (ideally within 1 meter).
• 🔌 Wi-Fi adapter malfunctions. If the laptop does not see not a single one network, including your home router, the adapter may have failed. Test it on another device or use an external USB adapter (costs from 300 rubles).
• 📱 Problems with the SIM card. If the phone does not catch the mobile network (there is no icon 4G/5G), Wi-Fi distribution will not work. Reboot your phone or move the SIM card to a different slot.

⚠️ Attention: If you are using VPN on the phone, Wi-Fi distribution may not work due to a routing conflict. Disable VPN before connecting your laptop or configure Split Tunneling (if this option is available in your VPN client).

7. Alternative connection methods if Wi-Fi does not work

If the Wi-Fi distribution stubbornly refuses to work, there are several workarounds:

• 🔌 USB modem. Connect your phone to your laptop with a cable and turn it on USB modem in the phone settings. It is more stable than Wi-Fi and is not affected by interference.
• 🔄 Bluetooth modem. On Windows: Settings → Devices → Bluetooth → Add device. On your phone, turn on Bluetooth modem mode. The speed will be lower, but it will be enough for mail or instant messengers.
• 🌐 Cloud proxy. If you only need access to certain sites (for example, for work), use Cloudflare Warp or Ngrok to create a secure tunnel through the phone.

FAQ: Frequently asked questions about connecting a laptop to Wi-Fi from a phone

❓ Why does my laptop connect to Wi-Fi from my phone, but it says “No Internet access”?

This is a problem with DNS servers or gateway. Try:

1. Set up DNS on your laptop 8.8.8.8 And 8.8.4.4 (Google) or 1.1.1.1 (Cloudflare).
2. Disable VPN or proxy on your phone (if they are enabled).
3. Reboot the phone - sometimes the operator “forgets” to assign an IP address for distribution.

❓ Is it possible to distribute Wi-Fi from a phone without a password?

Technically yes, but:

• On Android this is only possible with root rights or via ADB (command settings put global tether_dun_required 0).
• On iPhone The password is required - it cannot be removed.

Warning: An open network is dangerous - anyone can connect to it and intercept your traffic.

❓ Why does the laptop see the network from the phone, but does not connect with the error “Failed to obtain an IP address”?

This means that The DHCP server on the phone does not provide an IP. Solutions:

1. Assign a static IP on your laptop (instructions in section 3).
2. Reset your network settings on your phone (Settings → System → Reset → Reset Wi-Fi, mobile network and Bluetooth).
3. Try turning on/off modem mode on your phone.

❓ How to increase Wi-Fi distribution speed from your phone?

Speed depends on:

• 📶 Mobile network signal. If the phone has 1-2 bars of 4G, the speed will be slow. Bring your phone to the window or go out onto the balcony.
• 📡 Wi-Fi standard. If your phone supports Wi-Fi 5 (802.11ac), and the laptop is only Wi-Fi 4 (802.11n), the speed will be limited to 150 Mbit/s.
• 🔋 Energy saving mode. On Android disable it in battery settings.

Maximum speed when distributed from a phone, it rarely exceeds 50–70 Mbit/s (even with 5G). For stability, it is better to use a USB modem.

❓ Why does the laptop lose access to the local network after connecting to Wi-Fi from the phone?

This happens because of conflict routing metrics. Windows/macOS by default prioritizes the Wi-Fi network, disabling access to a wired network or VPN. Solutions:

• On Windows: open Control Panel → Network → Change adapter settings, right click on Ethernet → Properties → IP version 4 → Advanced and uncheck Automatic metric. Set the metric 1 for wired network and 2 for Wi-Fi.
• On macOS: in System Settings → Network drag and drop Ethernet higher Wi-Fi in the list of services.
