Don't rush to reset your router to factory settings or reinstall drivers—in 80% of cases, the problem can be resolved in 5 minutes with simple steps. Let's start with the most obvious!

1. Checking basic settings: router and computer

Before digging deep into your network settings, make sure the problem isn't just a surface issue. Users often spend hours troubleshooting when turning on Wi-Fi on their laptop or rebooting their router would have been enough.

Get started with these steps:

• 🔌 Check the router's power supply: The indicators on the case should light steadily (not blink randomly). If the light Wi-Fi or WLAN not active - press the wireless network enable button on the back panel (if available).
• 📡 Make sure Wi-Fi is turned on on your computer.:
  • On Windows: Click on the network icon in the tray → check that the mode is On the plane disabled, and the slider Wi-Fi active.
  • On macOS: the Wi-Fi icon should be lit in the menu bar (if not, turn it on System Preferences → Network).
• 🔄 Restart your router and computerUnplug the router from the power outlet for 30 seconds, then plug it back in. Restart your PC/laptop.
• 🔍 Check network visibility on other devicesIf your smartphone or tablet doesn't see Wi-Fi, the problem is with the router; if it does, it's with the computer.

If the network still doesn't appear after these steps, proceed to the next section. If the router visible, but connection fails (for example, it says "Failed to connect to the network") - the problem is different, and you need Instructions from the FAQ at the end of the article.

⚠️ Attention: On some routers (for example, TP-Link Archer C6 or ASUS RT-AX55) button Wi-Fi On/Off can be combined with a button WPSHold it for 3-5 seconds to turn on the wireless network.

2. Router settings: why the network may be hidden or disabled

The router may be turned on, but do not broadcast network Due to settings. This is a common reason why a computer can't see Wi-Fi, even though other devices are connected. Go to the router's web interface and check:

How to open router settings:

1. Connect your computer to the router via cable (or use another device that can see Wi-Fi).
2. Enter your router's IP address in your browser's address bar. This is usually:
   • 192.168.0.1 (For TP-Link, D-Link)
   • 192.168.1.1 (For ASUS, Zyxel)
   • 192.168.8.1 (for some models Huawei)

Enter login/password (by default it is often admin/admin or indicated on the router sticker).

In the router interface, check:

• 📡 Is SSID broadcast enabled?: in the section Wi-Fi or Wireless network there should be a check mark opposite Enable Wireless (or similar item). If the option Hide SSID active - the network is hidden and can only be connected to manually.
• 🔒 Wi-Fi operating mode: if the router is configured to only 5 GHz, and your computer only supports 2.4 GHz (or vice versa), the network will not be visible. Switch the router to the mode 2.4 GHz + 5 GHz or Dual Band.
• 🔄 Channel and channel width: if a rarely used channel is manually set (eg. 13 in mode 2.4 GHz), some devices may not see it. Try automatic channel selection (Auto).

3. Problems with the Wi-Fi adapter on your computer

If the router is working correctly, but the computer still does not see the network, the problem may be in Wi-Fi adapterThis applies to both built-in modules in laptops and external USB adapters.

How to check the adapter:

On Windows:

1. Click Win + X → select device Manager.
2. Expand the branch Network adapters.
3. Find the device with the names Wireless, Wi-Fi or 802.11 (For example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros QCA9377).
4. If the icon next to the adapter is lit ! or ? — the driver is not working properly.

On macOS:

1. Open About this Mac → System Report.
2. Go to the section Network → Wi-Fi.
3. Check the status: if it is written Disabled or Adapter not found — the problem is in the driver or hardware.

What to do if the adapter does not work:

• 🔄 Restart the adapter: V Device Manager Right-click on the adapter → Disconnect the device → wait 10 seconds → Turn on the device.
• 🔧 Update your driver:
  • Automatically: Click on the adapter → Update driver → Automatic search.
  • Manually: Download the driver from the website of the laptop or adapter manufacturer (for example, for Intel - With downloadcenter.intel.com).
• 💻 Check the physical connection: If you have an external USB adapter (for example, TP-Link TL-WN725N), try reconnecting it to a different port.
• ⚡ Reset network settings:
  • On Windows: Settings → Network & Internet → Status → Network reset.
  • On macOS: delete the network in System Preferences → Network and add it again.

⚠️ Attention: If after updating the driver Wi-Fi stops working completely, roll back the driver: in Device Manager select Properties → Driver → Roll Back DriverIf the button is inactive, uninstall the driver and reinstall it.

4. Channel conflicts and interference from other networks

In apartment buildings, Wi-Fi networks from neighboring routers can overlap each other, creating interference. If your computer can't see the network or the connection keeps dropping, the problem may be channel congestion.

How to check and fix:

Step 1: Analyze the broadcast

Use utilities to scan Wi-Fi networks:

• 📊 Windows: NetSpot, inSSIDer or WiFi Analyzer (from Microsoft Store).
• 🍎 macOS: built-in utility Wireless diagnostics (hold Option → click on the Wi-Fi icon → Open Wi-Fi diagnostics).

Step 2: Select a free channel

If in your range (2.4 GHz or 5 GHz) too many networks on one channel, change it in the router settings:

1. Go to the router's web interface (see Section 2).
2. Go to Wi-Fi → Wireless Network Settings.
3. Find the parameter Channel and choose the least busy one (for example, if everyone is sitting on 6, select 1 or 11).
4. Save the settings and reboot the router.

Step 3: Change the channel width

In mode 2.4 GHz channel width 40 MHz may cause interference. Try installing 20 MHz:

Wi-Fi → Settings → Channel Width: 20 MHz

Why does 2.4 GHz only have 3 non-overlapping channels?

There are 13 channels available in the 2.4 GHz band, but their widths overlap. Only channels 1, 6, and 11 do not overlap. If your router is on channel 3, it will interfere with the network on channel 1, and vice versa.

5. Incompatibility of Wi-Fi standards: 802.11a/b/g/n/ac/ax

Older computers or laptops may not support newer Wi-Fi standards (e.g. Wi-Fi 6 or 802.11ax), and modern routers sometimes disable support for outdated protocols to increase speed.

Critical Information: If your router is in the 802.11ax (Wi-Fi 6), and the adapter in the computer only supports 802.11n (Wi-Fi 4), the network may not be displayed or the connection may be unstable.

How to check compatibility:

• 🔍 Find out the standard of your adapter:
  • On Windows: V Device Manager Find the adapter model (for example, Broadcom 802.11ac) and play around with its characteristics.
  • On macOS: V System Report → Network → Wi-Fi look at the line Supported PHY modes.
• ⚙️ Configure the router's operating mode:
  • If the adapter is old (for example, only 802.11g), set the router mode 802.11b/g/n mixed.
  • If the router is new (for example, ASUS RT-AX88U With Wi-Fi 6), but the adapter does not support ax, turn it off 802.11ax in the settings.

Example of setting up a router TP-Link:

Wireless Mode → 802.11n/ac mixed (if the adapter does not support ax)
or
802.11b/g/n mixed (if the adapter is very old)

⚠️ Attention: If your computer was released before 2010, it may not support 5 GHzIn this case, configure the router to work only in the range 2.4 GHz or buy an external USB adapter (for example, TP-Link TL-WN823N).

6. Hardware malfunctions: when repairs are essential

If all software methods have been tried, but the computer still does not see the router, the problem may be in hardware failureLet's consider typical cases:

Router malfunctions:

• 🔌 Nutritional problemsIf your router is shutting down intermittently or the lights are flashing erratically, check the power supply. Try a different adapter with the same specifications (e.g., 12V 1A).
• 📡 Burnt out Wi-Fi moduleIf your router works via cable but doesn't broadcast Wi-Fi, the wireless module may be faulty. This is a common issue after power surges.
• 🔥 OverheatIf the router is hot to the touch, unplug it for 15-20 minutes. If the Wi-Fi works again after it cools down, the thermal paste needs cleaning or replacement.

Computer malfunctions:

• 💻 Damaged Wi-Fi module: In laptops, the cable often breaks off or the controller burns out. If the adapter is not detected even in Device Manager - this is a sign of hardware failure.
• ⚡ Problems with the USB port: If you are using an external adapter (eg. D-Link DWA-131), try connecting it to a different port or computer.

How to diagnose:

• 🔧 Check the router on another deviceIf none of your gadgets see Wi-Fi, the problem is with your router.
• 🖥️ Test your computer with another router.: if it doesn’t see any network, the problem is in the adapter.
• 🛠️ Inspect the equipment:
  • On the router: check if the connectors are melted or the capacitors are swollen.
  • On a laptop: If you're disassembling the device, make sure the Wi-Fi antennas are connected to the module (usually two thin wires).

Repair cost:

• Replacing the Wi-Fi module in a laptop: from 1,500 to 4,000 rubles (depending on the model).
• Router repair (replacement of power supply or Wi-Fi module): from 1,000 to 3,000 rubles.
• External USB adapter (if the built-in module burns out): from 500 to 2,500 rubles (for example, TP-Link TL-WN822N).

7. Viruses, firewalls and third-party programs

Sometimes the cause of Wi-Fi problems is software conflictsAntivirus programs, firewalls, or even viruses can block network access. Let's look at typical scenarios:

Firewall or antivirus is blocking the network:

• 🛡️ Temporarily disabling the firewall:
  • On Windows: Control Panel → Windows Firewall → Turn on or off.
  • On macOS: System Preferences → Security & Privacy → Firewall.
• 🦠 Antivirus check: V Kaspersky, ESET NOD32 or Avast There may be a "Network Protection" option - temporarily disable it.
