1. Connecting via Ethernet cable (the most reliable method)

If there is a computer near you router or a modem with a port LAN, the easiest and most stable way is to connect them network cable (also known as twisted pair or Ethernet). This method does not require additional devices, provides maximum speed and minimal delays (ping).

What you will need:

• 🔌 Network cable (usually comes with the router; if not, buy one) Patch Cord length 1–5 meters).
• 🖥️ Free port LAN on the router (usually yellow).
• 💻 Port Ethernet on the computer (if you don’t have one, you will need one) USB-Ethernet adapter).

How to connect:

1. Insert one end of the cable into the port LAN on the router (not to be confused with WAN!).
2. Connect the other end to the port Ethernet on PC.
3. Wait for the network to be automatically detected (usually takes 5-10 seconds).
4. If the Internet does not work, check if it is turned on Obtaining an IP address automatically in the network adapter settings (Control Panel → Network Connections → Ethernet → Properties → Internet Protocol Version 4 (TCP/IPv4)).

⚠️ Attention: If you have ADSL modem (for example, from Rostelecom old model), adjustment may be required PPPoE connections Manually. The login and password for connection are usually specified in the contract with the provider.

2. Using a USB modem (4G/5G)

If a wired connection is not possible (for example, the router is far away or there is no router at all), an alternative is USB modem with mobile internet support. This is a compact device that plugs into a port USB and catches the signal 4G/5G from telecom operators (MTS, Beeline, MegaFon, Tele2).

Advantages of the method:

• 🚀 Quick deployment - just insert the modem and install the drivers.
• 📶 Works wherever there is mobile network coverage (even without a router).
• 🔄 Can be moved to another computer or laptop.

Cons:

• 💰 Requires the purchase of a modem (from 1,500 ₽) and payment for a higher traffic plan.
• 📉 Speed ​​depends on the signal level and base station load.
• 🔋 Consumes power from the USB port (may drain your laptop's battery faster).

How to set up:

1. Buy a USB modem (popular models: Huawei E3372, ZTE MF823, Yota Many).
2. Insert SIM card with an active tariff (for example, "Unlimited Internet" from MegaFon).

4. Connect your computer to the created network as if it were a regular Wi-Fi network.

On iPhone (iOS):

1. Go to Settings → Tethering.
2. Enable the option Allow others.
3. Connect your PC to the network iPhone via Wi-Fi or USB (the last option saves phone battery).

⚠️ Attention: When connecting via Wi-Fi Your smartphone will drain quickly. To save battery, use USB connection (The phone will charge from the computer.) Also, keep an eye on your data limit—some carriers block data tethering on unlimited plans.

Make sure you have enough money in your account|Check your data plan's traffic limit|Turn Airplane mode on and off (reset network settings)|Connect your phone to a charger (if you're sharing via Wi-Fi)|Set a password for your hotspot (minimum 8 characters)-->

4. Connecting via a second computer or laptop (network bridge)

If you have a second computer or laptop with Wi-Fi, it can be used as intermediary for distributing the Internet via cable or through BluetoothThis method is called "network bridging" (Network Bridge) and works on Windows, macOS And Linux.

How to set up a bridge on Windows 10/11:

1. Connect the second computer (with Wi-Fi) to the Internet.
2. Connect both PCs Ethernet cable or turn on Bluetooth on both.
3. On the donor computer, open Control Panel → Network and Sharing Center → Change adapter settings.
4. Select Wi-Fi And Ethernet (or Bluetooth), right-click and select Setting up the bridge.
5. Wait for the bridge to be created (may take up to a minute).
6. The Internet should work automatically on the second computer.

⚠️ Attention: When setting up a bridge through Bluetooth The speed will be limited to ~1–3 Mbps, which is only enough for instant messaging and lightweight websites. For stable operation, it's better to use Ethernet.

Alternative method (without bridge) - ICS (Internet Connection Sharing):

• 🖱️ On a computer with Wi-Fi, open Wi-Fi adapter properties → Access.
• 🔗 Check the box Allow other network users to share your Internet connection.
