1. Check if your computer has a Wi-Fi adapter

Before attempting to connect to the router, make sure your computer is physically capable Find Wi-Fi. In 90% of cases, connection problems are due to a missing or faulty adapter.

On laptops The Wi-Fi module is built in by default (except for some gaming or budget models). But desktop PCs are often sold without it - in this case you will need to buy a separate adapter (from 500 ₽ for a USB version to 3000 ₽ for a PCIe module with support Wi-Fi 6).

To check if the adapter is present:

• 🖥️ On Windows: click Win + R, enter devmgmt.msc and find the section Network adaptersLook for lines with words Wireless, Wi-Fi, 802.11 or brand names (Intel, Qualcomm Atheros, Realtek).
• 🐧 On Linux: open terminal and run the command:

  lspci | grep -i network
  iwconfig

  If there is a mention in the output wlan0 or wlp — There is an adapter.

• 🍎 On macOS: click on the icon Wi-Fi in the menu bar → Open Network Preferences → "Wi-Fi"If the section is active, the adapter is working.

If the adapter is not in the list:

• 🔍 For desktop PC: acquire USB Wi-Fi adapter (we recommend models on a chip Realtek RTL8812BU for Windows or Intel AX200 for Linux/macOS) or PCIe card (For example, TP-Link Archer T6E For Wi-Fi 6).
• 🔄 For laptop: Check if the adapter is disabled hardware button (on some models Lenovo or HP there is a separate switch).

⚠️ Attention: If in Device Manager If the adapter is displayed with an exclamation mark, this indicates a driver issue. Don't download drivers from third-party sites—use official sources (Intel Driver & Support Assistant or the laptop manufacturer's website).

The adapter is detected in the system | Drivers are installed (no exclamation marks) | The adapter is physically turned on (button/switch) | The router is turned on and distributing the network (check on the phone) -->

2. Preparing the router for connection

Even if the adapter on the computer works, the problems may be on the side routerBefore connecting, please perform basic checks:

1. Make sure the router is turned on. and indicator Wi-Fi (usually indicated by an antenna icon 📶) is on without blinkingIf the indicator is flashing or inactive, press the button. WPS/Wi-Fi on the router body (on some models ASUS And Zyxel wireless network is disabled by default).

2. Check that the router distributes IP addresses via DHCP. To do this:

• 🌐 Connect to the router via cable or another device (phone/tablet).
• 🔧 Open your router's control panel (usually at 192.168.0.1 or 192.168.1.1, login/password — admin/admin or indicated on the sticker).
• 📋 Go to the section DHCP (at TP-Link This Advanced Settings → Network → DHCP Server). Make sure the server is turned on.

3. Check Wi-Fi operating mode:

⚠️ Attention: If your router supports Wi-Fi 6 (802.11ax), but the computer connects at speed Wi-Fi 4, check the adapter settings in Device Manager (adapter properties → "Additionally" → parameter Wireless Mode). Sometimes compatibility mode is set by default.

3. Step-by-step instructions for connecting to Wi-Fi on Windows 10/11

• 🔄 Try connecting to the network 5 GHz instead of 2.4 GHz (or vice versa) - sometimes helps with interference.

4. Connecting to Wi-Fi on Linux (Ubuntu/Debian)

On Linux The connection process depends on the desktop environment you are using (GNOME, KDE, XFCE). Let's consider a universal method through terminal and graphical interface NetworkManager.

Method 1: Via a graphical interface (GNOME/KDE)

1. Click on the network icon in the upper right corner (📶).
2. Select your network from the list.
3. Enter your password and click "Connect".

Method 2: Via terminal (for all distributions)

If the graphical interface is not available, use the command nmcli:

# View available networks
nmcli dev wifi list

Connect to the network (replace SSID and PASSWORD)
nmcli dev wifi connect "NETWORK_NAME" password "PASSWORD"

Method 3: Manual configuration (if DHCP does not work)

If your router doesn't assign an IP address automatically, configure the network manually:

sudo nano /etc/network/interfaces

Add lines (replace parameters with your own):

auto wlan0
iface wlan0 inet static
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.1
wpa-ssid "NETWORK_NAME"
wpa-psk "PASSWORD"

Restart the network:

sudo systemctl restart networking

⚠️ Attention: On some distributions (for example, Arch Linux) instead of NetworkManager is used netctl or wpa_supplicantIn this case, the network configuration must be written in /etc/wpa_supplicant/wpa_supplicant.conf.

5. Connecting to Wi-Fi on macOS

On MacBook or iMac Connecting to Wi-Fi is as simple as possible, but there are some nuances with some routers (especially with WPA3).

Step 1. Click on the icon Wi-Fi in the menu bar (📶). If the icon is not there, open it System Preferences → Network and turn on Wi-Fi.

Step 2. Select a network from the list. If there is no network:
