When you don't have a router at hand but need internet access urgently, your smartphone can become a full-fledged access point. Modern Android-devices and iPhone support the function modem mode, allowing you to distribute mobile traffic over Wi-Fi, Bluetooth or through USB cableIn this article, we'll focus on the most convenient and fastest way—connecting your laptop to your phone wirelessly.
The advantage of this method is obvious: there's no need for additional cables, and the data transfer speed often exceeds alternative options. However, many users encounter issues, from a lack of connection to sudden disconnections. We'll cover not only the basic setup, but also hidden parameters affecting connection stability, as well as typical errors that interfere with correct operation.
Important: Functionality may vary depending on the smartphone model and operating system version. For example, on iPhone With iOS 17 The access point activation algorithm has changed slightly compared to iOS 15, and on some Android-devices from Xiaomi or Samsung There are additional power saving settings that affect Internet distribution.
1. Preparing your smartphone: checking compatibility and tariff
Before setting up internet tethering, make sure your tariff plan supports this feature. Many operators (MTS, Beeline, Megaphone, Tele2) include modem mode in basic packages, but some budget tariffs may block it or limit the speed.
How to check:
- 📱 Open your carrier's mobile app (e.g. My MTS or MegaFon. Personal account).
- 🔍 Find the "Services" or "Additional Options" section - there should be information about the modem mode there.
- 💬 Dial the USSD command to check the tariff (for example,
*111#For Beeline or*105#For Megaphone). - 📞 Call your carrier's support team and check if tethering is allowed under your plan.
Also pay attention to traffic limitSharing the internet with a laptop consumes data much faster than regular smartphone use. For example, watching videos on 1080p on YouTube through the laptop it "eats" up to 3 GB per hour, and online gaming or downloading files can use up to 10–15 GB in a few hours.
⚠️ Attention: On some tariffs, operators charge an additional fee for using the modem mode, even if it is formally permitted. For example, Tele2 can cheat 5–10 ₽ per day for internet distribution on tariffs without unlimited traffic.
2. Setting up a hotspot on Android
The process of turning on the access point on Android is almost the same for all devices, but the menu item names may differ. We'll look at the universal algorithm and then point out the specifics for popular brands (Samsung, Xiaomi, Huawei).

5-10 minutes. - 🔋 When connecting via USB (if the laptop supports it) iPhone will be charged, which is convenient for long-term work.
- 📶 On iPhone 12 and newer is supported
5Gin modem mode, but it depends on the operator.
⚠️ Attention: On iOS Cannot change network name (SSID) - it always corresponds to the name of the device (for example, Ivan's iPhone). This can cause conflicts if there are others nearby. iPhone with the same name.
4. Connecting a laptop to an access point
Once the hotspot on your smartphone is activated, all that's left to do is connect your laptop. The process is almost identical for Windows 10/11 And macOS, but there are differences in the interface.
For Windows:
- Click on the icon Wi-Fi in the lower right corner of the taskbar.
- In the list of available networks, find the name of your access point (the one you set on your smartphone).
- Enter your password and click
Connect. - If the connection does not occur, check if the airplane mode on a laptop.
For macOS:
- Click on the icon Wi-Fi in the top panel.
- Select your network from the list.
- Enter the password and confirm the connection.
- If the network is not displayed, refresh the list of networks using the keys
Option + Clickby the Wi-Fi icon.
After a successful connection, a notification about the internet connection will appear on the laptop, and an active access point icon will appear on the smartphone (usually in the top notification bar).
What to do if the laptop does not see the access point?
Check if Wi-Fi is turned on on your laptop (sometimes it is turned off by pressing the keys) Fn + F2/F3). Make sure that the hotspot is actually active on your smartphone (sometimes it turns off when you lock the screen). Try restarting both devices. If you are using 5 GHz, check if your laptop's Wi-Fi adapter supports it (especially on older models).
5. Connection optimization: how to increase speed and stability
Even if a connection is established, speed may be slow and the connection may be unstable. Here are the key parameters to pay attention to:
1. Selecting a Wi-Fi band:
- 📡
2.4 GHz— passes through walls better, but is susceptible to interference from other devices (microwaves, neighboring networks). - 🚀
5 GHz— higher speed and less interference, but worse coverage (does not penetrate thick walls).
2. Wi-Fi channel: If there are many networks in your area 2.4 GHz, they may conflict. Use apps like Wi-Fi Analyzer (Android) or NetSpot (macOS/Windows) to find the least loaded channel and set it manually in the access point settings.
3. Limiting connected devices: The more gadgets are connected to the access point, the lower the speed for each one. Android You can limit the number of devices (usually up to 5–10), and on iPhone This is done automatically.
4. Energy saving: On Android disable battery optimization for the app Settings or Access point (depending on the model). On iPhone make sure that the low power mode (Low Power Mode) is disabled - it may limit the modem's performance.
6. Typical problems and their solutions
Even with proper setup, errors can still occur. Let's look at the most common ones and how to fix them.
