How to connect to Wi-Fi via WLAN: Complete instructions for all devices

Connecting to a wireless network via WLAN Wireless Local Area Network (WLAN) is a basic procedure that every user of modern gadgets faces. Despite its apparent simplicity, many still make mistakes during setup, resulting in slow internet, constant connection drops, or complete inability to connect. In this article, we'll cover all the current WLAN connection methods on various devices, including rare cases where standard methods fail.

It is important to understand that the terms Wi-Fi And WLAN are often used as synonyms, but technically WLAN is a broader concept covering any wireless local area network, and Wi-Fi is a specific implementation of the standard IEEE 802.11We will focus on practical applications: from connecting a smartphone to setting up complex corporate networks with WPA3-EnterpriseWe'll pay special attention to common issues such as invisible networks, authentication errors, and IP address conflicts.

If you've previously encountered a problem where your device "sees" the network but doesn't connect, or the connection drops after a few minutes, you'll find solutions in this article. We'll also cover hidden WLAN mode (SSID hiding), which many people mistakenly consider a reliable protection against hackingSpoiler: this is a myth, and we will explain why.

What is WLAN and how is it different from Wi-Fi?

Before we move on to setup, let's clarify the terminology. WLAN (Wireless LAN) is a general term for any wireless local area network that operates according to standards IEEE 802.11. Wi-Fi — is a trademark that certifies the compatibility of devices with 802.11 standards. Essentially, when you connect to Wi-Fi, you're using a WLAN, but not every WLAN is necessarily Wi-Fi certified.

Key standards relevant in 2026:

  • 📶 802.11ax (Wi-Fi 6/6E) — supports up to 9.6 Gbps, optimized for dense networks (apartment buildings, offices).
  • 🔄 802.11ac (Wi-Fi 5) - up to 3.5 Gbps, still common in budget routers.
  • 🛡️ WPA3 — the latest security standard (required for Wi-Fi 6 certification).
  • 🚫 WEP - outdated protocol, can be hacked in minutes (do not use!).

In practice, the difference between WLAN and Wi-Fi for the user is minimal, but it is important to understand that:

  • 🔧 Settings WLAN adapter in Windows or Linux they may be called exactly that, and not "Wi-Fi".
  • 📡 Some corporate networks use WLAN with 802.1X authentication (via login/password or certificates), which is not typical for home routers.
  • 🌍 In some countries (e.g. Germany), the term "WLAN" is used more often than "Wi-Fi" due to legal issues with the Wi-Fi Alliance brand.

    Troubleshooting common Wi-Fi connection errors

    Even with the correct settings, the connection may fail due to specific errors. Let's look at the most common ones.

    1. "Unable to connect to the network" (Windows/macOS)

    • 🔌 Check what the router is distributing DHCP-addresses (in settings) LAN the DHCP server must be enabled).
    • 🔄 Restart your router and device. If that doesn't help, reset your network settings:
      • On Windows: Settings → Network & Internet → Status → Network reset.
      • On macOS: see spoiler above.
    • 🛡️ Temporarily disable your firewall (Windows Defender, Kaspersky, Avast).

    2. "Authentication..." or "Obtaining IP address..." (Android/iOS)

    • 📵 Make sure your password doesn't contain Cyrillic characters or spaces (some routers don't support them).
    • 🔒 Check the security type: if the router is configured to WPA2/WPA3 Mixed, try to set only WPA2-PSK.
    • 📡 Switch from 5 GHz to 2.4 GHz (or vice versa) - some devices perform poorly on higher channels.

    3. The network is not displayed in the list

    • 🔍 Check that the router is not in the "Secure Mode" mode. Hide SSID (hiding the network name).
    • 📡 Make sure your device is within range: some routers (ASUS RT-AX88U) have a weak signal at the periphery.
    • 🔄 Change the channel on your router: if used DFC-channel (52-144), some devices do not see it.

    4. There is a connection, but the Internet doesn't work.

    • 🌐 Check that the router is not turned on Parental Control or MAC address filtering.
    • 🔧 Manually enter DNS: in the connection settings, specify 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
    • 📡 Reboot your router and wait until it is fully loaded (indicator Internet should be green).
    ⚠️ Note: If the error occurs only on one device, while others connect normally, the problem is most likely with the drivers or settings of that device. To diagnose this, try connecting to a different network (for example, using your phone in hotspot mode).

    WLAN Security: How to Protect Your Network from Hacking

    Connecting to a Wi-Fi network isn't just a matter of convenience, it's also a matter of security. Incorrect settings can lead to data leakage or unauthorized use of your internet connection. Let's look at key security measures.

    1. Selecting a safety standard

    • 🔒 Use WPA3-PSK (if all devices support it) or WPA2-PSK (in mode AES, and not TKIP).
    • 🚫 Never use WEP or Open network - they are hacked in seconds.
    • 🛡️ Use on corporate networks WPA2-Enterprise With 802.1X (for example, through Radius server).

    2. Setting up a password

    • 🔑 The password must be at least 12 characters long, with a mix of letters, numbers, and special characters (e.g. k7#pL9!mQ2$vR).
    • 📝 Do not use personal information (birthdates, names) or standard combinations (12345678, qwerty).
    • 🔄 Change your password every 6 months (or more often if you suspect a leak).

    3. Additional protective measures

    • 🌐 Turn it off WPS (Wi-Fi Protected Setup) is a vulnerable protocol that can be hacked in a few hours.
    • 📡 Turn on MAC address filtering (but remember that this is not a panacea - MAC is easy to counterfeit).
    • 🕶️ Create Guest network For friends, it is isolated from your main network.
    • 📈 Turn on Beamforming And Mu-MIMO (if your router supports it) - this will improve speed and reduce the risk of data interception.

    4. Hiding SSID: Myths and Reality

    Many users mistakenly believe that hiding the network name (Hide SSID) protects against hacking. In fact:

    • 🔍 Hidden SSID visible in any traffic analyzer (Wireshark, Airodump-ng).
    • 📡 Devices have to constantly scan the air, which increases energy consumption and reduces connection speed.
    • 🔧 Some devices (eg. Amazon Echo) cannot connect to hidden networks.

    FAQ: Answers to frequently asked questions

    Is it possible to connect to WLAN without a password?

    Technically yes, but only if the network is open (no encryption) or you know the vulnerability (eg. WPS with vulnerability Pixie Dust). However:

    • Connecting to someone else's secure network without permission is violation of the law (in the Russian Federation it is regulated by Article 272 of the Criminal Code "Unauthorized access to computer information").
    • Open networks (like those in cafes) can intercept your traffic. Always use VPN.
    Why does Windows 10/11 keep losing WLAN connection?

    A common cause is the adapter's power settings:

    1. Open device Manager → find your Wi-Fi adapter.
    2. Right click → Properties → Power Management.
    3. Uncheck the box Allow the computer to turn off this device to save power.

    Also check:

    • Update your adapter driver (especially important for Realtek And Mediatek).
    • Disable it in your router 8
