If your computer doesn't have a Wi-Fi adapter and you don't plan on buying an external module, this guide will help you get by with standard tools. We've tested all the methods on Windows 10/11 and phones Samsung Galaxy S23, Xiaomi Redmi Note 12, Google Pixel 7 with the latest firmware updates. The data is relevant for all versions. Android starting with 8.0 Oreo.

1. Preparing your phone: checking your plan and settings

Before sharing the Internet, make sure that your tariff supports it. tethering (traffic distribution). Many operators block this function on cheap packages or impose an additional fee. For example, Tele2 Unlimited internet may limit tethering speed to 64 kbps after 10 GB, and Yota completely prohibits distribution on tariffs without the "Modem" option.

To check restrictions:

• 📱 Open your carrier's app (e.g. My MTS or My Beeline).
• 🔍 Find the "Services" or "Additional Options" section - there should be information about tethering there.
• 💬 Write in the support chat: "Does my plan support Internet tethering to other devices?"
• 📊 Check your personal account on the operator's website - sometimes restrictions are indicated in the tariff description.

⚠️ Note: If your operator blocks tethering, you can bypass the restriction by VPN (For example, 1.1.1.1 from Cloudflare) or change TTL in the phone's engineering menu. However, this may violate the terms of the contract—use at your own risk.

Also check the settings Android:

1. Go to Settings → Connections → Mobile networks → Hotspot & tethering.
2. Make sure the Wi-Fi hotspot switch is turned on (even if you plan to use USB or Bluetooth).
3. In the "Access point settings" menu, set a strong password (at least 8 characters, with numbers and letters).

2. Method 1: Connecting via USB (the most stable)

Internet distribution USB cable — the optimal option for desktop PCs: minimal battery consumption, high speed (up to 300 Mbps on USB 3.0) and no lag. Suitable for online gaming, video conferencing, or downloading large files.

Instructions for Windows 10/11:

1. Connect your phone to your PC using the original cable (cheap Chinese cables may not transfer data).
2. On the phone in the menu Settings → Connections → Hotspot & Tethering Activate "USB modem".
3. On your computer, wait for the drivers to be installed (usually Windows does this automatically). If the driver is not installed, download it from the phone manufacturer's website (for example, Samsung Smart Switch for devices Samsung).
