How to Connect a Laptop to Wi-Fi via a Phone: A Complete Guide

When you don't have a router at hand and you urgently need internet on your laptop, a smartphone becomes a lifesaver. Modern Android And iPhone can distribute mobile traffic Wi-Fi, USB or Bluetooth — simply enable tethering. But how do you do it correctly to avoid wasting extra gigabytes and connection errors?

This article provides detailed instructions for all connection methods, a comparison of their speeds and power consumption, and solutions to common problems. We'll cover the nuances for Windows 10/11 And macOSWe'll explain how to save data and why your smartphone isn't visible in the network list. Important: When distributing Wi-Fi via your phone, iOS Some operators block this function - check the tariff conditions in advance.

1. Preparation: What to check before connecting

Before you enable tethering, make sure:

  • 📶 There is one on the phone mobile Internet (3G/4G/5G). Check the signal indicator—if there's no network, Wi-Fi sharing won't work.
  • 🔋 Charging your phone's battery above 30%Sharing the internet quickly drains your battery, especially over Wi-Fi.
  • 📱 On your smartphone no active VPNs or proxy - they can block the laptop's connection.
  • 💻 On a laptop the Wi-Fi adapter is turned on (on Windows check in Control Panel → Network Adapters).

It's also worth checking whether your plan supports tethering. Some operators (for example, Tele2 or Yota) limit this feature or charge an additional fee for it. How to check? Log in to your operator's personal account or send a USSD request:

  • 📱 MTS: *111*0887#
  • 📱 Beeline: *102#
  • 📱 Megaphone: *105*00#
⚠️ Please note: If you are connected to a corporate or school network (e.g. eduroam), sharing Wi-Fi via a phone may violate an organization's security policies. In some cases, this can lead to SIM card blocking.

2. Method 1: Sharing Wi-Fi from your phone (access point mode)

The most popular and fastest method is to turn your smartphone into Wi-Fi router. The connection speed will depend on the generation of the mobile network (maximum up to 1 Gbit/s on 5G), but on average it will be 30–100 Mbps. Let's look at the instructions for Android And iPhone separately.

For Android (Samsung, Xiaomi, Honor, etc.)

The algorithm is the same for most models, but the menu item names may differ slightly. For example, on Xiaomi Redmi Note 12 the path will be like this:

  1. Open Settings → Connections → Hotspot & Tethering.
  2. Tap on Mobile hotspot.
  3. Turn on the slider and configure the network settings:
    • 🔐 Network name (SSID): come up with something unique (eg. MyPhone_Hotspot).
    • 🔑 Password: minimum 8 characters, preferably with numbers and letters.
    • 📡 Range: select 5 GHz for greater speed (if the laptop supports it).
  • Connect your laptop to the created network as if it were a regular Wi-Fi network.
  • For iPhone (iOS 15 and later)

    On iPhone the function is called Modem modeTo activate it:

    1. Go to Settings → Tethering (or Settings → Cellular → Personal Hotspot).
    2. Turn on the slider Allow others.
    3. Set a password (by default it is generated automatically).
    4. On your laptop, find the network with your name iPhone (For example, Ivan's iPhone) and connect.
    5. On iPhone There's one caveat: if you don't connect to the hotspot for 90 seconds, it automatically disconnects. To avoid this, connect at least one device (for example, a second phone) or disable the function. Max. compatibility in the modem mode settings.

      Make sure mobile internet is working on your phone

      Enable hotspot mode in settings

      Check network visibility on a laptop

      Enter the correct password (case sensitive!)
