How to Add a Wi-Fi Network: A Complete Guide for All Devices

Connecting to a Wi-Fi network is a basic task faced by every gadget user. However, even such a simple operation can be challenging if the device doesn't detect the network, requires non-standard settings, or operates with outdated security protocols. In this article, we'll explore all possible scenarios for adding a Wi-Fi network. smartphones, laptops, televisions And smart devices, including solutions for hidden networks, corporate access points and compatibility issues.

We will pay special attention to connecting to networks with WPA3-Enterprise — This protocol is increasingly used in offices and educational institutions, but it causes difficulties for users due to the need to enter login/password manually. We'll also look at how to add a network if its name (SSID) hidden, or if the device does not support modern encryption standards.

Whether you are setting up a new one router TP-Link Archer AX6000 or trying to connect an old printer HP LaserJet P1102 To connect to a wireless network, here you will find step-by-step instructions taking into account the features of different operating systems and types of equipment.

1. Adding a Wi-Fi network on smartphones (Android and iOS)

Mobile devices are the most common clients of Wi-Fi networks. The connection process on Android And iOS similar, but there are nuances associated with OS versions and manufacturers (for example, Samsung One UI or Xiaomi MIUI may have their own settings).

On Android 12+ The path to Wi-Fi settings is standard: Settings → Network & Internet → Wi-FiA list of available networks will be displayed here. If the network you want is hidden, click Add a network at the bottom of the screen and enter SSID, security type (WPA2-PSK, WPA3-SAE etc.) and password. On iPhone (iOS 15+) go to Settings → Wi-Fi, select a network from the list or click Another network for manual input.

• 📱 Android: In some firmware (for example, ColorOS from Oppo) you may need to confirm the connection via SMS or push notification.
• 🍎 iOS: If the network uses 802.1X Enterprise, you will need to install the certificate through Settings → General → VPN and device management.
• 🔒 Hidden networks: On both types of devices, when manually adding a hidden network, make sure the box is checked Hide SSID is not active (otherwise the device will not be able to connect automatically).

⚠️ Attention: On Android 10 and below some devices do not support WPA3-PersonalIn this case, you will have to temporarily roll back your router settings to WPA2-PSK or update your smartphone's firmware.

2. Connecting to Wi-Fi on laptops (Windows, macOS, Linux)

On Windows 11 Adding a Wi-Fi network is done through the taskbar: click the network icon → select the desired access point → enter the password. If the network is not listed, click Hidden network and enter the data manually. Windows 10 the path is similar, but the interface may differ depending on the build (for example, in Windows 10 LTSC (Notification center missing).

On macOS Ventura+ go to System Preferences → Network → Wi-FiHere you can not only connect to the network, but also set the connection priority (useful if the laptop often moves between several access points). For Linux (For example, Ubuntu 22.04) use the applet NetworkManager in the taskbar or the command in the terminal:

nmcli dev wifi connect "SSID" password "password"

⚠️ Attention: On Linux when connecting to networks with 802.1X (for example, in universities) manual file configuration may be required /etc/wpa_supplicant/wpa_supplicant.confReady-made configurations are often posted in organizations' IT departments.

Check if the Wi-Fi adapter is enabled (Fn+F2 or in BIOS)

Update your network card driver (especially for Realtek RTL8821CE)

Disable VPN (may block DHCP)

Reboot your router if the network is not displayed-->

3. Adding Wi-Fi to Smart TVs and media set-top boxes

Televisions Samsung, LG, Sony Bravia and prefixes (Apple TV 4K, Nvidia Shield, Xiaomi Mi Box) connect to Wi-Fi through the settings menu. For example, on Samsung QLED 2022+ the path is this: Settings → General → Network → Open network settings → WirelessThe main problem here is lack of keyboard to enter the password. Solutions:

• 📺 Samsung/LG: Use a remote with a microphone for voice input or connect a USB keyboard.
• 🍎 Apple TV: Enter your password through the app Apple TV Remote on iPhone.
• 🎮 Android TV: Install the application TV Remote Control on your smartphone for simplified input.

If the TV does not see the network at the frequency 5 GHz, check your router settings: some models (for example, TCL 4-Series) support only 2.4 GHz. Also on old TVs (Sony 2016 and earlier) support may be missing WPA3 — in this case, you will have to enable compatibility mode in the router WPA2/WPA3 Mixed.

What should I do if my TV won't connect to Wi-Fi?

1. Check if the router is in the "Secure Mode" mode. 802.11r Fast Transition - It may cause problems with older devices.

2. Try to manually specify DNS (for example, 8.8.8.8) in the TV network settings.

3. If used IPv6, disable it in your router - some TVs do not support this protocol.

4. Connecting smart devices (IoT) to Wi-Fi

Smart bulbs (Xiaomi Yeelight, Philips Hue), sockets (TP-Link Tapo), cameras (Ezviz, Hikvision) and others IoT gadgets often require special apps to connect to Wi-Fi. The general algorithm:

1. Download the manufacturer's official app (for example, Mi Home for devices Xiaomi).
2. Register an account (sometimes you need to link it to a phone number).
3. Put your device into pairing mode (usually by holding down the button Reset 5-10 seconds).
4. In the application, select Add a device and follow the instructions (you may need to enter your Wi-Fi password or scan a QR code).

The main challenges when connecting IoT:

• 🌐 2.4 GHz only: Most smart devices don't work on 5 GHzMake sure your router is broadcasting a network within the range 2.4 GHz (sometimes it needs to be enabled separately in the settings).
• 🔄 Network change: If you change your Wi-Fi password, many IoT gadgets will need to be reconnected via a reset.
• 🛡️ Safety: Avoid using WEP or open networks - this makes devices vulnerable to hacking.

5. Connecting to corporate and public Wi-Fi networks

The network in an office, university or hotel often uses WPA2/WPA3-Enterprise with authentication via 802.1XTo connect you will need:

1. Login and password (issued by the network administrator).
2. Security Certificate (can be installed via .p12 or .cer file).
3. Setting up a connection profile (manually or via a configurator, for example, SecureW2).

On Windows:

1. Go to Control Panel → Network and Internet → Network and Sharing Center → Set up a new connection.
2. Select Connecting to a wireless network manually.
3. Please specify SSID, security type WPA2-Enterprise or WPA3-Enterprise, authentication method (PEAP, TTLS or EAP-TLS).
4. Enter your login/password and import the certificate if necessary.

On Android/iOS The process is similar, but you may need to install a special application (for example, eduroam CAT to connect to the network eduroam in universities).

⚠️ Note: Some corporate networks use client isolation (Client Isolation), which prevents devices from seeing each other on the local network. This is normal and not a malfunction.

6. Troubleshooting adding a Wi-Fi network

If your device does not connect to Wi-Fi, check the following:

For diagnostics on Windows use commands in CMD:

ipconfig /all
ping 8.8.8.8
nslookup google.com

On Android install the application WiFi Analyzer To check the signal strength and channel congestion, try resetting the network settings on your device:

• 📱 Android: Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings.
• 💻 Windows: Settings → Network & Internet → Network reset.

7. Security when adding new Wi-Fi networks

When connecting to public or unknown networks, follow these rules:

• 🔐 Use VPN (For example, ProtonVPN or Windscribe) to encrypt traffic.
• 🚫 Turn it off File sharing in network settings (on Windows: Control Panel → Network and Internet → Network and Sharing Center → Change advanced sharing settings).
• 📵 Don't save passwords for public networks on your device.
• 🔄 Regularly remove unnecessary networks from the list of saved ones (on Android: Settings → Wi-Fi → Saved Networks).

For home network:

• 🔄 Change your Wi-Fi password every 3–6 months.
• 🛡️ Use WPA3-Personal (if all devices support it).
• 📡 Disable WPS - This protocol is vulnerable to brute force attacks.
• 👤 Turn on MAC address filtering (although this is not a panacea for hacking).

⚠️ Warning: Do not use simple combinations like 12345678 or qwertyModern hacking programs (for example, Aircrack-ng) pick up such passwords in a few minutes.

FAQ: Frequently asked questions about adding Wi-Fi networks

Is it possible to connect to Wi-Fi without a password?

Technically yes, but only if the network is open (no encryption) or you know WPS-PIN router. In other cases, a password will be required. Some public networks (for example, in cafes) grant access after authentication via social media or SMS.

Why can my phone see the network but my laptop can't?

Possible reasons:

• The laptop does not support the range 5 GHz (check in Device Manager Wi-Fi adapter model).
• The network card driver is out of date (update via device Manager or the manufacturer's website).
• The router is in the enabled mode 802.11ac Only, and the laptop only supports 802.11n.

How to connect a printer to Wi-Fi?

For most printers (HP, Canon, Brother) the algorithm is as follows:

1. Turn on the printer and set it to Wi-Fi mode (usually the button Wi-Fi or WPS).
2. On your computer, run the manufacturer's utility (for example, HP Smart).
3. Select the network and enter the password. Alternatively, connect via WPS (click the button WPS on the router for 2 minutes).

If your printer doesn't connect, check if it supports it. WPA3 - many old models (Canon Pixma MG3600) work only with WPA2.

What's happened SSID and where can I get it?

SSID (Service Set Identifier) ​​is the name of your Wi-Fi network. It appears in the list of available networks on your devices. If the network is hidden, SSID you can find out:

• On the router sticker (usually located next to the password).
• In the router's web interface (192.168.0.1 or 192.168.1.1, chapter Wireless).
• Via the Windows command line: netsh wlan show networks.

How to add a second Wi-Fi network on one device?

Most devices support connection to only one Wi-Fi network at a time. However:

• On Android 10+ you can use the function Wi-Fi Direct to connect to multiple devices without a router.
• On Windows can be created virtual adapter through CMD (requires administrator rights).
• Some routers (eg. Asus RT-AX88U) support guest network, which can be connected in parallel with the main one.
