How to connect your all-in-one PC to the internet via Wi-Fi from your phone: a complete guide

Today, all-in-one PCs remain a popular solution for home and office use thanks to their compact size and performance. But what if you don't have a cable or router handy and need internet access urgently? Sharing Wi-Fi from your phone — a universal way to access the Internet from any device, including all-in-one PCs Windows, macOS or LinuxThis method is especially useful when traveling, at the dacha, or during temporary internet outages.

The connection process seems simple, but in practice, users encounter nuances: from mobile operator restrictions to the specifics of Wi-Fi adapter drivers in all-in-one PCs. In this article, we'll cover every step—from setting up a hotspot on your smartphone to diagnosing speed or connection issues. You'll learn how to avoid common mistakes and maximize connection stability, even if your all-in-one PC was released 5+ years ago.

⚠️ Important: Mobile operator tariff parameters (e.g., data tethering restrictions) may change. Please check the current terms in your personal account or with your operator.

1. Preparation: What to check before connecting

Before you enable the hotspot on your phone, make sure all system components are ready to work. Start by checking mobile Internet on smartphone:

• 📶 Network signal: The phone should have at least 2-3 signal strength bars. In areas with poor coverage (for example, EDGE or 3G) the speed will not be sufficient for comfortable work.
• 💳 Tariff plan: Many operators limit or block internet tethering on basic plans. Check if your plan supports this feature. Hotspot (sometimes called "Modem Mode").
• 🔋 Battery charge: Wi-Fi hotspots consume a lot of power. If your phone's charge is below 30%, connect it to a charger.

Next, check monoblock:

• 🖥️ Wi-Fi adapter: Make sure it's turned on. Windows This can be done through Control Panel → Network Adapters or a keyboard shortcut (for example, Fn + F2 on some models HP or Lenovo).
• 🔄 Drivers: Outdated drivers may cause connection issues. Update them via device Manager (section "Network adapters").

⚠️ Attention: If your all-in-one has previously connected to other Wi-Fi networks, remove them from the list of saved networks. A setting conflict may prevent you from connecting to the new access point.

2. Setting up a hotspot on Android

The settings interface may differ slightly depending on the version. Android (10, 11, 12+) and manufacturer's shells (MIUI, One UI, ColorOS etc.). We will consider a universal algorithm:

1. Open "Settings" and go to the section Network and Internet → Access Point and Modem (or Connections → Mobile Hotspot on Samsung).
2. Activate "Mobile Hotspot"On some phones (eg. Xiaomi) you will need to confirm permission to use mobile data.
3. Configure network settings:
   • 🔐 Network Name (SSID): Please provide a unique name (eg. MyPhone_Hotspot). Avoid Cyrillic letters and spaces.
   • 🔒 Password: Use a combination of 8+ characters (Latin, numbers, symbols). Example: Hot5pot_2026!.
   • 📡 Range: If you have a choice, choose 2.4 GHz - It is better suited for older all-in-one PCs.

Once activated, a notification with the network name and password will appear on the screen. Remember or take a photo of this information—you'll need it to connect to the all-in-one PC.

⚠️ Attention: on some phones (eg Huawei With EMUI) After connecting the device, the hotspot may automatically disconnect after 5-10 minutes. To avoid this, disable the "Data Saver" feature in your mobile network settings.

3. Setting up a hotspot on iPhone (iOS)

On iPhone The process of distributing the Internet is called "Modem mode". The algorithm is the same for iOS 14–iOS 17, but there are nuances with operators:

1. Open Settings → Personal Hotspot (or Cellular → Personal Hotspot (on some versions).
2. Activate the "Allow others" sliderIf the option is inactive, check:
   • 📱 Cellular communications: Make sure your mobile internet is turned on.
   • 🔄 iOS Update: on older versions (below iOS 12) support may be missing Wi-Fi 5.

Set up a password: by default iPhone Generates a complex password, but you can change it in the same section. An example of a strong password: iPh0ne_H0tsp0t!.

Once activated, a blue bar will appear on the lock screen with the text "Tethering: 1 connection." This means the network is ready for use.

⚠️ Attention: if after connecting the monoblock the internet is on iPhone It stops working, check your settings. VPN or Mobile data limitSome applications (eg. 1.1.1.1) may conflict with the modem mode.

4. Connecting the all-in-one PC to Wi-Fi from your phone

Now let's move on to the all-in-one computer. The instructions are universal for most models (HP Pavilion, Lenovo IdeaCentre, Apple iMac etc.), but the paths to the settings may differ.

For Windows 10/11:

1. Click on the icon Wi-Fi in the lower right corner of the taskbar.
2. In the list of available networks, find the access point name (the one you set on your phone).
3. Click "Connect" and enter the password. If the all-in-one doesn't see the network, refresh the list using the button Refresh.
4. Once connected, check your internet access by opening your browser.

For macOS:

1. Click on the icon Wi-Fi in the top menu bar.
2. Select your phone's network and enter the password. macOS Ventura and newer may require confirmation via Touch ID.
3. If the connection does not occur, open System Preferences → Network and remove the phone network from the list, then try connecting again.

⚠️ Attention: on monoblocks with Linux (For example, Ubuntu or Mint) manual configuration may be required DHCPIf you don't have internet access after connecting, run the following in the terminal:

sudo dhclient -r
sudo dhclient wlan0

(Where wlan0 — the name of your Wi-Fi adapter, check it with the command ip a).

5. Solving typical problems

Even with proper setup, difficulties can arise. Let's look at the most common ones:

Problem 1: The all-in-one PC doesn't see the phone's network.

• 🔍 Check network visibility: Make sure the hotspot is turned on (the notification should be lit on your phone).
• 📵 Turn off Airplane Mode: on a candy bar and phone.
• 🔄 Change Wi-Fi channel: Try the channels in your phone's hotspot settings. 1, 6 or 11 (they are less busy).

Problem 2: There is a connection, but no internet

• 🌐 Check your mobile internet: Open a browser on your phone and make sure that websites load.
• 🔧 Reset network settings: On the monoblock, run the following commands:

  ipconfig /release
  ipconfig /renew

  (For Windows) or restart the network service on macOS/Linux.

• 📱 Disable VPN/Proxy: on the phone and all-in-one PC - they can block traffic.

Problem 3: Slow speed or dropped connections

• 📶 Check your signal level: If there are 1-2 bars on the candy bar, move the phone closer (within 2-3 meters).
• 🔋 Disable background tasks: On your phone, close apps that consume traffic (for example, YouTube, Torrent clients).
• 🔄 Change the protocol: In your phone's hotspot settings, select WPA2-PSK instead of WPA3 (the latter may not be supported by older all-in-one PCs).
Why is the speed via tethering lower than on my phone?

When connecting via a hotspot, some bandwidth is wasted on maintaining the connection. Furthermore, many operators artificially limit the speed in modem mode (for example, to 10–20 Mbps even with a 100 Mbps plan).

⚠️ Attention: If the all-in-one connects, but the connection breaks after 1–2 minutes, check the power saving settings on your phone. Android Disable the "Turn off mobile data during sleep" option in the section Battery → Power Saving Mode.

6. Optimize the connection for stable operation

To minimize lag and improve speed, follow these tips:

• 📡 Use 5 GHz (if supported): This band is less crowded and offers higher speeds, but has a shorter range. It's suitable if the all-in-one PC and the phone are in the same room.
• 🔋 Connect your phone to the charger: When the battery level drops below 20%, many smartphones automatically reduce the Wi-Fi transmission power.
• 🚫 Disable automatic updates: Pause the download of updates on your all-in-one PC Windows/macOSso that they do not consume traffic.
• 📱 Activate the "Maximum Performance" mode: on Android This can be done in the battery settings for the Hotspot app.

Critical nuance: if you use USB modem (connecting the phone to the all-in-one via cable), the speed will be higher than via Wi-Fi, but you will need to turn it on USB modem in your phone's settings. This method also saves battery life.

Connection method	Speed	Stability	Battery consumption
Wi-Fi (2.4 GHz)	Up to 50 Mbps	Average (may contain interference)	High
Wi-Fi (5 GHz)	Up to 200 Mbps	High (when close)	Very tall
USB modem	Up to 100 Mbps	Very high	Short
Bluetooth	Up to 10 Mbps	Low	Average

7. Alternative methods of distributing the Internet

If Wi-Fi is not working for some reason, consider other options:

• 🔌 USB modem: Connect your phone to the all-in-one PC with a cable and enable tethering in the settings. This method is more stable than Wi-Fi and drains the battery less.
• 🔵 Bluetooth: Suitable for transferring small amounts of data (for example, for instant messaging apps). Speed ​​is low, but battery consumption is minimal.
• 📶 External 4G modem: If you often have to share the Internet, buy a USB modem (for example, Huawei E3372). It is more stable than the phone and does not drain its battery.

⚠️ Attention: when using USB modem on macOS You may need to install additional drivers (for example, for chips) Qualcomm). Download them from the phone manufacturer's website.

8. Security: How to protect your connection

Sharing Wi-Fi from your phone creates potential risks:

• 🔓 Unauthorized access: If you don't set a password, outsiders will be able to connect to your network, which will reduce speed and increase the risk of data leakage.
• 🕵️ Traffic interception: When using public networks (for example, in a cafe), attackers can intercept data transmitted through your access point.

To minimize risks:

• 🔐 Use a strong password: at least 12 characters with a combination of letters, numbers and signs.
• 🔄 Disable the access point: when it is not needed, especially in public places.
• 🛡️ Enable the firewall: On the all-in-one PC, activate the built-in Windows Defender or Firewall on macOS.
• 🌐 Use a VPN: If you're transmitting sensitive data (for example, logging into online banking), connect to a VPN on your all-in-one PC.

⚠️ Attention: If you are distributing the Internet in a place with a large crowd of people (airport, train station), change the network name (SSID) to neutral (for example, Office_123), so as not to attract attention.
