My router isn't distributing Wi-Fi, but I have internet via cable. What should I do?

You have connected the provider's cable to the router, the indicator WAN The light is green, and the computer's internet connection via Ethernet works fine. But here's the problem: The Wi-Fi network is either not displayed in the list of available networks, or devices connect but do not have internet access.Sound familiar? It affects one in five users, and the causes can range from simple glitches to hardware malfunctions.

In this article we will discuss all possible scenariosWhy did the router stop distributing Wi-Fi while the wired internet was working? You will receive step-by-step instructions for diagnosis — from checking settings to testing hardware, as well as a table with typical errors and their solutions for popular models (TP-Link, ASUS, Keenetic, Zyxel etc.). Don't rush to take your device to a service center: in 90% of cases, the problem can be fixed yourself in 10–30 minutes.

Before you take any action, answer two questions:

1. Is the indicator light on? Wi-Fi on the router body? (If not, the problem may be in the wireless module).
2. Does the network see at least one device (for example, a smartphone), even without internet access? (If so, the problem is in the distribution settings, not the hardware.)

1. Rebooting your router is the first and most effective step

It sounds trivial, but Up to 40% of support requests from providers are resolved with a simple reboot.The problem is that routers (especially budget models) are prone to freezing due to overheating, power surges, or firmware errors. While wired internet may still work, the Wi-Fi module does not.

How to reboot correctly:

• 🔌 Physical shutdown: unplug the router from the socket 30–60 secondsDon't press the button. Reset - this will reset the settings!
• ⚡ Via the web interface: Go to the control panel (usually at the address 192.168.1.1 or 192.168.0.1), find the section System → Restart.
• 📱 Via mobile app: in applications Tether (For TP-Link), ASUS Router or Keenetic There is a reset button.

After turning on, please wait 2-3 minutes — The router needs time to initialize the modules. If the Wi-Fi indicator lights up but the network is still not visible, proceed to the next step.

2. Check that Wi-Fi is enabled in the router settings

Sometimes the wireless network is disabled by software - for example, after a power failure, firmware update, or accidental button press Wi-Fi On/Off on the body. This can only be checked through the web interface.

Instructions for most models:

1. Connect to the router via cable (or via another device if Wi-Fi is working at all).
2. Open your browser and enter your router's IP address. This is usually 192.168.1.1 or 192.168.0.1 (check the sticker below).
3. Enter login/password (by default it is often admin/admin).
4. Find the section Wireless network (or Wi-Fi, Wireless).
5. Make sure the checkbox is checked Enable wireless broadcasting (or Enable Wireless) costs.

If this option is disabled, enable it and save the settings. Afterwards, the router may require a reboot.

Where to find Wi-Fi settings on popular models

• TP-Link: Basic → Wireless
• ASUS: Wireless Network → General
• Keenetic: Wi-Fi network → Access point
• Zyxel: Network → Wi-Fi → Basic Settings
• D-Link: Wi-Fi → Basic Settings

⚠️ Attention: If after turning on Wi-Fi in the settings the network still doesn't appear, check if the box is ticked Hide SSID (Hide SSID). In this case, the network will not be displayed in the list, but you can connect to it manually by entering its name.

3. Reset the router to factory settings

If rebooting and checking the settings did not help, the next step is full configuration resetThis is relevant if:

• 🔄 You recently changed your settings and after that, your Wi-Fi stopped working.
• 📱 The router returns an error when trying to save changes in the web interface.
• 🔧 The Wi-Fi indicator blinks abnormally (for example, red).

How to reset settings:

1. Find the small hole marked on the back of your router. Reset or Default.
2. Take a paper clip or a toothpick and press and hold the button 10-15 seconds (before the blinking of the indicators changes).
3. After the reset, the router will reboot. Reconfigure it using the information provided by your provider (usually included in your contract).

If you don’t remember your connection settings (for example, the type PPPoE/DHCP or login/password), please contact your provider's support. For most operators (for example, Rostelecom, Beeline, MTS) this data is duplicated in your personal account.

Set up an internet connection (WAN)|Turn on Wi-Fi and set a network name (SSID)|Set a Wi-Fi password (minimum 8 characters)|Update firmware (if available)|Check network operation of devices

-->

⚠️ Attention: On some routers (for example, Keenetic) A factory reset does not erase the firmware, but it does return all network settings to default. If you are using static IP from the provider, you will have to enter it again!

4. Checking the Wi-Fi channel and operating mode

If the network is visible, but the devices do not connect or the Internet is unstable, the problem may lie in incorrectly selected channel or operating mode. This is especially relevant in apartment buildings with many neighbors using routers.

How to check and change settings:

1. Go to the router's web interface (instructions above).
2. Go to the section Wireless Network → Channel Settings (or Wireless → Channel).
3. Try manually selecting a channel from the list (for example, 6 or 11 for the range 2.4 GHz). Avoid automatic mode (Auto).
4. Make sure the operating mode is set as 11b/g/n mixed (For 2.4 GHz) or 11a/n/ac mixed (For 5 GHz).
5. Save the settings and reboot the router.

If you have a dual-band router (dual band), check the settings separately for 2.4 GHz And 5 GHzSometimes the problem occurs in only one of the ranges.

5. Updating the router firmware

Outdated or faulty firmware is a common cause of Wi-Fi outages. Manufacturers regularly release updates that fix compatibility issues, security vulnerabilities, and wireless connectivity problems. You can check the firmware's current status in the web interface.

Step-by-step instructions:

1. Go to your router's control panel.
2. Find the section System → Firmware Update (or Administration → Firmware Upgrade).
3. Click Check for updatesIf a new version is available, download and install it.
4. Do not turn off the router during the update! The process may take 2-5 minutes.
5. After the update, the router will reboot automatically.

If automatic update does not work, download the firmware from official website of the manufacturer for your model and upload it manually. Be careful: Incorrectly selected firmware can brick the router, making it inoperable..

⚠️ Attention: On some routers (for example, ASUS with firmware Merlin) After the update, user settings are reset (for example, DNS or Port Forwarding). Write them down in advance!

6. Checking the hardware: antennas, ports, power

If software methods do not help, the problem may be in ironHere's what you need to check:

• 📡 Antennas: Make sure they are screwed tightly (on some models, for example TP-Link Archer C6(The antennas may come loose due to vibration.) Try slightly rotating them in different directions.
• ⚡ Power unit: If the router's lights are flashing erratically or are dim, the power supply may be faulty. Try a different adapter with the correct specifications (the voltage and current must match!).
• 🔌 Ports: Inspect the connector WAN (for internet cable) and LAN- ports. If the contacts are bent or oxidized, the router may not recognize the connection correctly.
• 🔥 Overheat: If the router case is hot, unplug it for 15-20 minutes. Dust on the heatsink or fan (if present) can cause malfunctions.

If you suspect a hardware problem but aren't confident in your ability to fix it, it's best to contact a service center. Diagnostics typically cost from 500 rubles, while repairs (such as replacing a Wi-Fi module) will cost between 1,000 and 3,000 rubles, depending on the model.

How to test a power supply without a multimeter

If you have another router with the same power port, try connecting its adapter. If the problem goes away, your adapter is faulty. Don't use power adapters with different specifications (such as a phone adapter), as this could damage the router!

7. Alternative methods of distributing Wi-Fi

If the router stubbornly refuses to distribute Wi-Fi, but the Internet via cable works, you can use temporary solutionsuntil the device is repaired:

• 💻 Distribution from a computer: Connect your PC to the router via cable, then turn it on. Mobile hotspot (in Windows 10/11: Settings → Network & Internet → Mobile Hotspot).
• 📱 Distribution from a phone: Connect your smartphone to the router via cable (via OTG adapter) and turn it on Modem mode → USB modemThen share Wi-Fi from your smartphone.
• 🔄 Additional router: If you have a second router, connect it to the first one via cable (in LAN port) and configure it as a repeater or a separate access point.

These methods will not replace the full functionality of your main router, but will allow you to temporarily provide your devices with Internet access.

FAQ: Frequently asked questions about Wi-Fi issues on your router

Why doesn't the router distribute Wi-Fi, but the cable internet works?

This is a typical situation when The router's wired and wireless modules operate independentlyThere may be different reasons:

• Software failure (resolved by rebooting or resetting).
• Wi-Fi is disabled in the settings.
• Wi-Fi module malfunction (requires repair).
• Channel conflict with neighboring networks.

Start with a reboot, then check the settings as described in the article.

How do you know if your Wi-Fi module is burned out?

Signs of hardware failure:

• The Wi-Fi indicator does not light at all (even after reset).
• There is no section in the router settings Wireless network or it doesn't open.
• The router does not respond to changes in Wi-Fi settings (for example, it does not save a new network name).
• When connected to power, the module becomes very hot or emits a burning smell.

In this case, the router needs to be repaired or replaced.

Is it possible to repair a router yourself?

If the problem is software-related (firmware failure, incorrect settings), yes. But if the hardware is faulty (for example, a burned-out Wi-Fi module), repairs will require:

• Soldering station (for replacing microcircuits).
• Knowledge in radio electronics.
• Spare parts (Wi-Fi module for your model).

Without experience, it is better to contact a service center; self-repair can make the problem worse.

What should I do if the router doesn't turn on after a reset?

Possible causes and solutions:

• Incorrect firmware update: Try to return to the old firmware via TFTP-mode (instructions are available on the manufacturer’s forums).
• Power failure during reset: Disconnect the router from the network for 10 minutes, then connect it again.
• Hardware failure: If the indicators do not light at all, check the power supply and cable.

If the router does not respond to a reset, the memory chip may be damaged, which requires professional repair.

How to protect your router from future failures?

Preventive measures:

• Use uninterruptible power supply (UPS) to protect against power surges.
• Regularly (once every 3-6 months) update the firmware.
• Do not place the router in enclosed spaces (such as a closet) as this may cause it to overheat.
• Periodically clean the case from dust (you can use a vacuum cleaner at minimum power).
• Avoid using your router beyond its capabilities (for example, connecting 20+ devices to a budget model).
