My laptop won't connect to Wi-Fi, but my phone still works. What should I do?

Your The laptop does not connect to Wi-Fi, even though your smartphone or other devices on the same network are working reliably, the problem is localized within the laptop itself. The first thing to check is whether the wireless adapter has been accidentally disabled (using Fn+F2/F12 or in Windows settings) and whether the "No internet connection" or "Failed to connect" error is displayed. Causes range from software glitches (outdated network card driver, software conflict) to hardware issues (damaged Wi-Fi module after a fall or overheating). Ignoring the problem can lead to a complete loss of connection, so it's important to act immediately—diagnosing the drivers and checking the router settings.

In this article we will look at all possible scenariosWhy doesn't the laptop detect Wi-Fi or can't connect to the network, while other devices are working reliably? You will receive step-by-step instructions For Windows 10/11 And macOSYou'll also learn when to contact a service center. We'll pay special attention to diagnostics—this will help save time and avoid unnecessary troubleshooting.

Before you begin tweaking settings, make sure the issue isn't temporary. Restart your router (unplug it for 30 seconds) and your laptop. If the connection isn't restored after this, read on.

1. Checking basic network settings on a laptop

Start with the obvious: maybe airplane mode turned on accidentally, or Wi-Fi was turned off manually. Windows Check your notification panel (the network icon in the lower right corner). macOS Look at the menu bar at the top of the screen - there should be a Wi-Fi icon there.

If the network icon is crossed out or missing, follow these steps:

• 🔄 Restart your laptopThis sometimes resolves temporary network adapter issues.
• 📡 Turn on Wi-Fi manuallyOn . Windows: Start → Settings → Network & Internet → Wi-Fi (The switch must be in the "On" position). Mac: Click the Wi-Fi icon in the menu bar and select "Turn on Wi-Fi".
• ⚡ Check airplane modeIt can be activated by keys. Fn + F2 (or another function key, depending on the laptop model). Windows 11 also look at Settings → Network & Internet → Airplane Mode.

If after these steps the laptop still does not see the network, proceed to the next section. The problem occurs especially often after updating Windows or drivers—the system may reset the adapter settings.

2. Diagnosing the network adapter in Device Manager

If Wi-Fi does not turn on or the laptop does not see any networks, the problem may be in network adapter driver or disabling it at the system level. Let's check this through device Manager:

1. Click Win + X and select "Device Manager".
2. Expand the "Network adapters" section.
3. Find the device with the words Wireless, Wi-Fi or Network Adapter (For example, Intel Wi-Fi 6 AX200, Qualcomm Atheros QCA61x4).
4. If there is an exclamation mark next to the adapter or it is displayed as "Unknown device", the driver is not working correctly.

What to do next:

• 🔄 Update your driverRight-click the adapter → "Update driver" → "Search automatically." If Windows doesn't find any updates, download the driver from the laptop manufacturer's website (see the "Support" section).
• 🗑️ Uninstall and reinstall the driverRight-click → "Uninstall device." After restarting, Windows will attempt to install the driver automatically.
• 🔌 Turn on the adapter if it is disabledRight-click → "Enable".

Make sure the adapter is not disabled (no gray arrow icon)

Update the driver via the context menu

Check for an exclamation mark (yellow triangle)

Restart your laptop after changes-->

On macOS similar problems are solved through System Preferences → NetworkIf the adapter does not appear in the list of interfaces, a reset may be required. NVRAM (press Option + Command + P + R when you turn on your Mac).

⚠️ Attention: If after uninstalling the driver your laptop stops detecting Wi-Fi completely, connect to the internet via cable (Ethernet) or USB modem to download the latest driver version.

3. Reset network settings and TCP/IP parameters

If the adapter works, but the laptop does not connect to Wi-Fi (for example, it says “Failed to connect to the network” or “Limited access”), the problem may be in network configurationsLet's reset the settings to factory defaults:

On Windows 10/11:

1. Open Settings → Network & Internet → Status → Network reset.
2. Click "Reset Now" and confirm. The laptop will restart.

If the reset does not help, run the commands in Command line (run it as administrator):

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

On macOS:

1. Open Terminal (via Spotlight or Programs → Utilities).
2. Enter the commands one by one:

   sudo ifconfig en0 down
   sudo ifconfig en0 up
   sudo networksetup -setdhcp Wi-Fi

   (instead of en0 May be en1 - check through ifconfig).

After the reset, try connecting to Wi-Fi again. If the problem persists, check your router settings—your laptop may be blocked by MAC address or device filtering may be enabled.

4. Checking router settings and device filtering

If your laptop won't connect to Wi-Fi but your phone works, the problem may be with your router settings. Go to your router's web interface (usually at 192.168.0.1 or 192.168.1.1, login/password - on the router sticker) and check:

Also pay attention to limit on the number of devicesSome routers (especially those from ISPs) block new connections if the limit is exceeded. In this case, disconnect one of the devices or increase the limit in the DHCP settings.

⚠️ Attention: If you rent a router from a provider, some settings (such as encryption type) may be locked. In this case, please contact technical support.

5. Hardware Problems: How to Test Your Wi-Fi Adapter

If none of the software methods helped, it might be the network adapter is out of orderThis is especially true for laptops that are frequently moved or dropped. Signs of hardware failure:

• 🚫 The laptop doesn't see it not a single one Wi-Fi networks (even public ones).
• 🔌 The Wi-Fi icon in the system is missing or displayed with a cross.
• 🔧 In Device Manager The adapter is marked as "Unknown device" or is missing altogether.

How to diagnose:

1. Check the adapter on another deviceIf you have a USB Wi-Fi adapter, connect it to your laptop. If it works, the built-in adapter is faulty.
2. Check if the Wi-Fi indicator is on (if there is one on the laptop case). The absence of an indicator may indicate a broken connection.
3. Disassemble the laptop (If you have experience) and check that the adapter is connected to the motherboard. Sometimes the contacts become oxidized or loose.

If the adapter is truly broken, it can be replaced. Universal modules are suitable for most laptops. M.2 2230 (For example, Intel AX200 or Broadcom BCM94360). The cost of replacement at a service center is from 1,500 to 3,000 rubles (depending on the model).

What does a network adapter look like in a laptop?

It is usually a small coin-sized board connected to the motherboard via a connector. M.2 or mPCIeIt has antenna wires (thin black or white cables) that run to the laptop's body. If the wires are loose or broken, there will be no signal even with a working adapter.

6. Conflicts with antiviruses and VPNs

Sometimes security programs Block Wi-Fi connections, mistaking them for a threat. Most often, the culprits are:

• 🛡️ Avast, Kaspersky, ESET NOD32 (Firewall module).
• 🌐 VPN clients (NordVPN, ProtonVPN), which change the routing of traffic.
• 🔒 Windows Firewall (may block new connections).

How to check:

1. Temporarily disable your antivirus and try connecting to Wi-Fi.
2. Disable VPN (if used).
3. Check your firewall settings: Control Panel → Windows Firewall → Allow an app to interact with this app.

If Wi-Fi works after disabling the antivirus, add the network to the exceptions or configure the firewall rules. Kaspersky, for example, this is done in the "Network" → "Packet Rules" section.

7. Updating the BIOS and router firmware

In rare cases, the problem lies in outdated router firmware or Laptop BIOSThis is relevant if:

• 🔄 My laptop stopped connecting to Wi-Fi after a Windows update.
• 📡 The router is new, but the laptop is old (or vice versa).
• 🖥️ In Device Manager The adapter is detected, but it works unstably.

BIOS update:

1. Find out your motherboard model (via msinfo32 in the line "System manufacturer and model").
2. Download the latest BIOS version from the laptop manufacturer's website.
3. Update via the manufacturer's utility (for example, Lenovo Vantage, HP Support Assistant) or manually via BIOS.

Updating the router firmware:

1. Go to the router's web interface (192.168.0.1 or 192.168.1.1).
2. Find the section Administration → Firmware Upgrade.
3. Download the firmware from the manufacturer's website and upload it through the interface.

⚠️ Attention: Updating the BIOS is a risky procedure. If the power goes out during the process, the laptop may become inoperable. Use an uninterruptible power supply (UPS) and do not interrupt the process.
