Today I decided to write an article on a very popular problem when the WLAN light on the router does not light up and there is no Wi-Fi network. That is, when the router stopped broadcasting Wi-Fi network. Router owners face this problem. different manufacturers: TP-Link, ASUS, D-Link, ZyXel, Tenda, Netis, etc. It doesn’t matter what router you have. If the Wi-Fi (WLAN) indicator on it has stopped lighting and the Wi-Fi network has disappeared, then now we will try to figure out this problem.
On different routers (different manufacturers and models) The WLAN indicator looks different. But it is on almost every router. As a rule, it blinks when data is being transferred via wireless network. The light bulb itself can be labeled "Wi-Fi", "2.4GHz", or "5GHz". Or maybe just an icon
In any case, when the WLAN indicator on the router is not lit or blinking, this is no longer normal. As you already understand, WLAN is Wi-Fi. Wireless network.
Most often, the problem is the following:
- Accidentally pressed the button to turn off Wi-Fi, which is found on many routers. After pressing it, the router stops distributing the Wi-Fi network, and the WLAN light, of course, does not light up. At the same time, the router continues to work and distributes the Internet via cable. But the devices no longer see the Wi-Fi network, since it doesn’t exist.
- Some kind of glitch in software. In this case, rebooting, resetting settings, or updating the router firmware helps. Also, you need to check Wi-Fi settings in the router control panel.
- Router failure. I have seen cases more than once when a router stopped distributing a Wi-Fi network due to a technical breakdown. If all else fails, the Wi-Fi indicator still doesn’t light up, then you need to take the router in for repair. (possibly under warranty), or buy a new one. If this is your case, then take a look.
Let's check this very button that turns off Wi-Fi on the router. Let's also check what's in the control panel. Because this is most often the problem.
The WLAN light does not light up, the router does not distribute Wi-Fi. What to do?
First of all, we take our router in our hands and look for a button on it that is responsible for turning it on/off wireless wifi networks. Typically, this button is labeled "Wi-Fi", "Wireless On/Off", or simply with a wireless network icon
Some routers do not have such a button.
If you find this button, just click on it once. Wait a little and look at the WLAN indicator, it should light up. If this does not happen, then reboot the router (turn off the power for a couple of minutes), and try pressing the button again. You can press and hold for three seconds. It all depends on the router and settings. In any case, this should help, and the router should distribute Wi-Fi.
Checking the status of the Wi-Fi network in the settings
If you don’t find the button, or if the WLAN network does not appear after clicking on it, you can also check the status of the wireless network in the router’s control panel.
We connect to our router via cable, there are no options here, and go to the settings. If you don’t know how to do this, then look. It may happen that you will not be able to access the control panel, in this case, see the article. If you can’t log in and the recommendations don’t help, then most likely the router is simply broken.
If you are lucky and the control panel opens, then look for the “Wireless Network”, “Wi-Fi”, “Wireless” tab and open it. It all depends on the model of your router. Let's look at the most popular ones.
This is what Wi-Fi settings look like on routers TP-Link :
Please note that the checkbox next to "Enable Wireless Router Radio" must be checked. (Enable wireless broadcasting).
On routers ASUS Open the "Wireless Network" section, "Professional" tab. Opposite the “Enable radio module” item, the switch should be next to “Yes”.
On ZyXEL Keenetic, in the "Wi-Fi network" section there should be a checkmark next to the "Enable access point" item.
If you have some other router, then the page with the wireless network settings will not be difficult to find. If it doesn’t work out, write the model in the comments, I’ll tell you.
Nothing helps, the router does not broadcast the Wi-Fi network, the indicator does not light up
If you have already tried everything possible, but the router still does not start distributing Wi-Fi, and the WLAN light still does not light up, then most likely the router is broken. That is, the problem is not in the settings or software, but in the hardware.
What else can be done?
- Reset your router to factory settings. Find the “Reset” button on the router, press and hold it for 10 seconds. As a rule, the button is recessed into the case, so you need to press it with something sharp. If that doesn’t work, type a query in the search on our website (at the very top), for example, “reset settings on TP-Link.” We have instructions for all popular manufacturers. Or write in the comments, I’ll tell you.
- If you were able to access the router settings, then update the firmware. We also have many instructions for different routers on our website. Look for instructions for your model through the site search.
To be honest, these tips are unlikely to help. But, before you take the router for repairs, or go to the store for a new one, you need to try resetting the settings and updating the firmware. Well, also press the "Wi-Fi" button (if you have it), maybe there is still a problem there, and the WLAN indicator will start to light up, and the router will distribute the wireless network.
Although we did not do any repairs WI-FI router ov, but they still approached us about this issue, and we could not refuse. The repair was quick and easy due to our experience and typical breakdown.
The very nice and powerful and not cheap router Asus Rt-n16 served for exactly a year, and the warranty has expired accordingly. If before it somehow turned on the third time, now it either does not light up at all, or it lights up for a couple of seconds and goes out and, accordingly, does not boot.
Judging by this gradually appearing breakdown, even before disassembly, we assumed that the power capacitor (in the router itself or in the power supply) may have dried out and lost its capacity, which in turn led to the loss of stable filtered power to the router processor.
First, let's find a similar power supply (with an output voltage of 12 Volts and a current of at least 1.25 and a plug polarity where the internal contact is a plus) and try to start from it. The test showed that on a new, working power supply unit the router behaves similarly.
On the power supply, in addition to the model name AMS3-120-1250FV, the inscription Amigo is funny :)
Let's start disassembling.
To find the screws that hold the case, it was enough to peel off the rubber feet of the case. Unscrew the screws and disassemble the router.
Immediately my gaze fell on a slightly swollen electrolytic capacitor with parameters of 16 Volts and 680 microfarads.
We solder from the back side of the board to its contacts with another capacitor with more or less similar parameters (100 mF 16 v was enough). The main thing is not to install a capacitor with a lower rated voltage so that it does not burn out.
The asus rt g32 router is a “classic” representative of the budget “line” of routers: the cost of the device does not exceed $25 - $30, and the model is available almost everywhere.
Despite its rather “respectable” age (the model first appeared on the international market more than six years ago), the asus rt g32 router is still very popular with such well-known providers as Rostelecom, Ukrtelecom, Dom ru and TTK, as well as operators cellular communications(Beeline, MTS, etc.). Which is quite natural: the cheaper the model, the easier it is to sell it to a trusting client.
However, any network equipment in this price category has its own “baggage” of shortcomings. And the asus rt g32 router, despite the “renown” of the manufacturer, was no exception here: many reviews note the poor design of the model, frequent crashes and “freezing” of the modem during operation, as well. Therefore, when choosing, you should pay attention to more modern models.
However, router rt g32 may well support a small home network with limited functionality. And this article presents short review router, and step-by-step instruction How to install and configure wifi router rt g32 yourself.
Router asus rt g32: functionality and technical specifications
WiFi access point rt g32 operates at a standard frequency of 2.4 GHz, and it is recommended for stable operation of the wireless network.
The security of information exchange here is ensured by the use of modern technologies: WEP, WPA and WPA2. At the same time, the nominal speed of receiving information via wi fi is only 150 Mbit/s - this is a fairly low figure compared to the same, where the maximum reaches 300 Mbit/s.
Asus rt g32 router: indicators
As usual, the indicator block of the asus rt g32 router is located on the front panel of the device and is limited to the “standard” set:
- - power indicator that lights up when the device is connected to the mains;
- - wi fi (WLAN) indicator that lights up when activated wireless connection with router asus rt g32;
- - WAN indicator, responsible for “delivery” of the Internet to the router. In other words, if this indicator is not lit, then you have “no Internet” - perhaps the provider has limited access to the service or there is a problem with the line;
- - four LAN indicators that light up when a network cable is connected to the corresponding connector on the back of the modem.
Asus rt g32 router connectors
On the back of the Wi-Fi router asus rt g32 there are:
- - a RESET button “hidden” in the device’s body, which is necessary to reset the router to factory settings;
- - round DC connector for connecting the router power adapter;
- - a separately located WAN connector for connecting the Internet cable provided by the provider.
- - four identical LAN connectors for cable connection external devices(we talked about how we did it ourselves in separate articles)
How to connect the Asus rt g32 router?
Authentication method - here feel free to choose WPA2-Personal (this is the most modern way data protection on a wireless network).
A WPA preshared key is a Wi-Fi password that protects your network from “free” WiFi lovers. It is recommended to set a complex, unique password for WiFi router asus rt g32, which will protect your router when trying to hack the network.
By the way, you can later change the password - this is also done in this section of the menu.
Setting up IP television on the asus rt g32 router is also carried out in “ Additional settings"in the WAN section, where you need to select the port to which the TV set-top box is connected and set a dynamic IP address for it

Preparing for firmware Asus router
Preliminary steps before flashing
Disconnect the router. It is advisable to disable network cable from WAN, take everything out USB ports
(otherwise, if there are connected disks, they may be disconnected incorrectly).
Resetting the router settings to default
First reset the router settings to default settings by choosing one of the following methods:
- by selecting in the router web shell: System Setup -> Factory Default.
- pressing a button on its body RESET for 5 seconds, light bulb POWER starts flashing, at this moment release the button.
- for experienced users who have already configured the router - commands " erase /dev/mtd/3" And " erase /dev/mtd/4"
(first you need to make sure that on your firmware version these sections correspond nvram And flashfs).
(on the back panel, its name depends on the model) and hold until the indicator POWER will not start blinking and only at this moment let go. After the reset, the device will automatically reboot.
Please note that at first there will be no reaction ( POWER will light up, fool proof), then it may just go out for a few seconds, keep holding the button.
Three methods for safely changing firmware Asus router
The first method is the simplest
Second method, for advanced users
Through the recovery utility Firmware Restoration(described in the manual, program rescue.exe on CD-ROM it's in a box). Difference between methods:
How to restore firmware on an ASUS router using the utility Firmware Restoration:
1. Connect the power supply to the router.
2. We are not supplying power to the router yet.
3. Connect the router with a patch cord to the Ethernet port of a PC running Windows XP / 7.
4. On this PC, turn off the firewall and all unnecessary network adapters, incl. and Wi-Fi, in addition to the network adapter - where the router is connected.
5. Install the ASUS Firmware Restoration utility on the PC (pre-downloaded from the website)
Rice. 1. Firmware Restoration utility.
6. Launch ASUS Firmware Restoration:
Rice. 2. Appearance of the utility window.
7. Specify the path to the required firmware file
Rice. 3. Path to the firmware file.
8. Next, press the RESET button on the back panel of the router and turn on its power supply. Hold the button down for about 5 seconds and on the PC, in the ASUS Firmware Restoration utility window, click the “Download” button. After this, the firmware update process begins. It takes about 3 minutes.
9. IMPORTANT!!! Do NOT turn off the power supply to the router until the flashing process is completed, the router DO NOT RESTART!!!
Nuances of IP address and subnet mask settings depending on the Asus router model
For models: ASUS RT-N13/DSL-N13/RT-N13U/RT-N15/RT-N16
(WL-320gP/320gE/330gE/500gP/500gPv2/500W/520gC/520gU/600g)
For models: ASUS RT-N11
For models: ASUS RT-G32
The third method, described in FAQ from Oleg
An analogue of the second method, described in the FAQ from Oleg: Firmware via tftp
(if changed IP address router, then you will need to look for it on it, and not on 192.168.1.1
)
How to restore firmware on an ASUS router through tftp
It is often necessary to erase all previously made changes to the router, for example, when switching from one type of firmware to another (necessarily from DD-WRT to Oleg and back).
To do this, the following “zeroing” firmware is used:
To recover after uploading the wrong firmware (for example from another model):
The firmware usually looks like this<модель роутера>-recover.trx
To completely clear nvram:
The firmware usually looks like this <модель роутера>-clear-nvram.trx
How to flash via tftp:
Preparation:
- Turn off the power of the device;
- Press the RESTORE button and hold it, turn on the power to the device;
- Wait until the POWER indicator starts flashing (about 1 second) and release the button;
- Take the network cable ( twisted pair), connect one tail to any of the LAN ports of the device, the other to network adapter Your PC;
- In Windows, for the TCP/IP protocol, assign the adapter the address 192.168.1.2 with a network mask of 255.255.255.0 (if the device had an address of 192.168.1.1);
- Run cmd.exe;
- Check that there is a connection with the device by running the command:
Something similar to:
Pinging 192.168.1.1 with 32 bytes of data: Reply from 192.168.1.1: bytes=32 time=2ms TTL=100 Ping statistics for 192.168.1.1: Packets: Sent = 1, Received = 1, Lost = 0 (0% loss) , Approximate round trip times in milli-seconds: Minimum = 2ms, Maximum = 2ms, Average = 2ms Control-C ^C
Press Control-C when you get tired of it. Pay attention to TTL=100 - this is the response of the built-in bootloader.
- We restore the firmware (firmware.trx must be replaced with the name of the file with the firmware);
We wait a few seconds, an inscription like
Transfer successful: 3706880 bytes in 7 seconds, 529554 bytes/s
- We wait from 2 minutes to 10 until the firmware is programmed and the AIR indicator lights up - the device has booted. If after 10 minutes AIR does not light up, then you need to turn the router on/off - autoboot did not work for some reason.
Note: PC owners with Windows Vista: the craftsmen at Microsoft surprised again: the tftp client (just like telnet) may not be present during the initial installation. You need to install it by visiting the Control Panel and selecting "Programs and...".
You can also use the tftp2 utility instead of the standard tftp command.
