How to return old firmware to a router. Restoring a D-Link Router After Unsuccessful Firmware

Hello friends! I was thinking that the setting Wi-Fi router For many, it’s just punishment and sheer torment. I made these conclusions from the comments to the relevant articles on this site. This is because routers themselves are very capricious devices. And let’s add to this various oddities of the Internet provider and devices that you are trying to connect to your router and you get a bunch of incomprehensible problems.

But if you have already managed to set everything up, then you need to consolidate this success. So that after resetting the router settings, updating the firmware, or other actions, you can restore the router settings in a few clicks of the mouse and restore its operation. This is what we will do now. I will write a short instruction on how to save the router settings to a file (let's create backup copy settings), and, if necessary, restore these settings.

I will show you using the example of a router TP-Link TL-MR3220. But it doesn’t matter, these instructions are suitable for all TP-Link routers. I don’t know what it’s like with routers from other companies. But I think that such a function should exist, except that the menu items are called a little differently.

Saving the router settings

Everything is very simple. On the router control panel there is a corresponding “Backup & Restore” item in which you can save and restore settings.

Go to the router settings. Don't know how to do this? And I write about this in almost every article :). Type the address in your browser's address bar 192.168.0.1 , or 192.168.1.1 and enter your login and password to access the router settings. By default these are admin and admin (address, logs and password can be found at the bottom of your router).

In Control Panel, go to the tab "System Tools" – .

And to save the settings to a file, click on the button “Backup” And "Save".

That's all, now we have saved the router settings in one file and we can restore them.

For example, you needed to do this, or for example, you wanted to experiment with the settings, you can always return to the operating parameters that we saved.

Restoring settings on a Wi-Fi router

In the same settings panel, go to the tab "System Tools" –.

Press the button "Review", select the file with the settings and click "Open".

Click the button.

Situation in which it is necessary to do restoring firmware on DIR-300 routers different revisions may arise due to various reasons. In addition to a malfunction in the firmware, when a WiFi router simply stops distributing the Internet and its web interface becomes unavailable, this could also be a simple rollback to the usual “stock” firmware after DD-WRT. Or it could be recovery after unsuccessful flashing when the router was fed firmware from a different hardware version.
In general, the developers - the D-Link company - foresaw a similar development of events on many modern devices made Emergency Web Server or Failsafe UI, which is essentially the same thing. Now let's figure out together how to use it.

Before doing anything with the router, you must first download the firmware from the official D-Link servers— ftp.dlink.ru :

You can find out what hardware version of DIR-300 you have on the sticker on back cover housings:

After that we go to the desired folder on the server, look for the “Firmware” directory there and download latest version firmware and the previous one, just in case. After that, we begin to conjure with a piece of iron. We disconnect the provider’s cable from it and all clients, except the computer from which we will do the recovery.
Then we do this - go to the Connections settings local network and manually enter the IP address in the properties of the TCP/IPv4 protocol 192.168.0.2 , mask 255.255.255.0 and the gateway - 192.168.0.1 :

You can register the addresses of DNS servers, or you can not - this is not important, because they will not be used. Click on OK and close the settings.

We take our DIR-300 in our hands and press the button Reset:

Keeping it pressed, turn off the power to the router with your other hand and turn it on again. Wait 15 seconds and release Reset.

Now you need to launch an Internet browser and enter the address in the address bar - http://192.168.0.1. The result should be like this:

There may be another nuance here. Earlier models DIR-300 interface disaster recovery was at a different address. Therefore, if your router does not respond to 192.168.0.1, then again go to the properties of the TCP/IP protocol and register the following IP:

IP: 192.168.20.80
mask:255.255.255.0

You also need to enter the address 192.168.20.81 in the address bar of the browser:

The interface of Emergency Web Server and Failsafe UI is actually the same - a file selection button, and a button to start flashing. Click on “Browse” and select the downloaded file with the firmware. Then click on “Upload” and wait for the process to complete.

What do we have as a result? Working router D-Link DIR-300! All the best!

Update and flashing software router, modem or optical terminal GPON is a common and normal thing for anyone network equipment. Bug fixes, bugs removed, new features added. But what to do if during this process there was a failure or the power was turned off and you now have an almost useless piece of plastic on your hands. But don’t despair - in some cases you can try to restore the router’s firmware after unsuccessful firmware. We will now tell and show you how this is done.

Advice: regardless of brand and WiFi models router, it is worth keeping in mind that in order to restore the device’s firmware, you need to connect it to the computer via wired connection Ethernet. Through wireless network The operation will not work! Only via cable!

How to restore a D-Link router

On most modems and WiFi routers D-Link has a special emergency interface, Emergency Web Server. On some models it was called Failsafe UI. This is a special firmware that allows you to restore the router’s firmware in the event of a failure. She's on these popular models like DIR-300, DIR-320, DIR-615, DIR-620. By the way, D-Link Emergency Web Server is very often used to return to the device factory firmware instead of the installed alternative (for example, Open-WRT, DD-WRT, Tomato, etc.).

So, in order to restore a Wi-Fi router after unsuccessful firmware, you must first download the firmware file from official server- ftp.dlink.ru. We find there the folder of our modem or router model, and in it - the folder Firmware.

Download the latest version of the software to your computer and put it in the root directory of some disk or on your desktop to make it easier to find.

The next step is to open Windows settings, go to the “Network and Internet” section and find the section Ethernet.

Note: There is another way to open the list of network connections. Press the Win+R keys and enter the command in the “Run” window ncpa.cpl.

Select a local network connection and right-click on it. A menu will appear in which you need to select “Properties”. A window will open where you need to double-click on the component IP version 4 (TCP/IPv4).

Another protocol properties window will appear, in which you need to check the “Use the following IP address” checkbox. The following must be entered below:

IP address: 192.168.0.2 Subnet mask: 255.255.255.0

Click on the OK button sequentially in each window to apply the changes. The network card has been prepared. After this, you need to turn off the router, hold down the Reset button with a paper clip and turn on the device again without releasing the button. You need to keep it pressed for about 30-40 seconds (sometimes a little longer). After that, release the reset, open the web browser and address bar enter the IP address: 192.168.0.1 . Press the “Enter” key. If everything worked out, the “Emergency Web Server” page will open.

Here you must first click on the “Browse” button, select the downloaded file with the firmware and click on the “Upload” button. This will start restoring the D-Link router firmware:

It is very important not to turn off or restart the router during the process. After the software is installed, you will see a standard web interface authorization window in your browser.

Attention! Don't forget to go back to the IP protocol settings and set automatic receipt addresses and DNS servers.

Restoring Zyxel keenetic firmware

In order to restore functionality Zyxel routers Keenetic developers made special utility — Keenetic Recovery. You can download it from the download center (). After you have downloaded and unpacked the archive, run the program. The following window should appear:

We carry out everything step by step exactly as written in the program. Namely, with the Kinetic router turned on, press Reset and hold it pressed until the “Status” indicator starts blinking. After this, release the Reset button. Utility Keenetic Recovery should automatically recognize the hardware version and start restoring the router firmware.

After this, you will need to perform the basic configuration of the device again, otherwise, with factory settings, as a rule, there will be no Internet access.

Emergency recovery of Sagemcom router firmware (Rostelecom, Tatelecom, Dom.ru)

Universal routers Sagemcom F@ST 2804, 1744, 3804 are provided to subscribers of the largest providers in Russia - Rostelecom, Dom.ru, etc. Unfortunately, they sometimes also have troubles in the form of crashed firmware after a power surge, or after an unsuccessful flashing. Fortunately, many sadzhemcoms also have a disaster recovery interface. To use it, you must first search the Internet and download the firmware for your router model.
Then on network card statically enter the IP address 192.168.1.2 - like this:

After that, turn off the router, press the “Reset” button with a pencil or fountain pen and turn it on again. We hold the button for 40-50 seconds, then release it. After that, launch the web browser and enter the IP of the router in the address bar. The following page should open:

Click the “Choose” button and select the firmware file. Then click on the button “ Update Software"and wait a few minutes while the router is being restored after unsuccessful firmware. After the process is completed, you will again have access to the device's regular web configurator. Don't forget to set the TCP/IP settings to automatically receive addresses.

How to restore QTech QBR-1040W and QBR-1041WU v2S

Another one popular brand Rostelecom routers and a number of other telecom operators - this is QTech. In particular, the QBR-1040W and QBR-1041WU v2S models. In order to perform emergency recovery of the router, you must first download current version firmware from the manufacturer's official website. We also need the TFTP32 program.
We start by registering the IP address 192.168.1.2 on the network card of a computer or laptop, as I already described above. Next, we connect the computer and the second LAN port of the router, labeled LAN2.
The next step is to use a pencil to hold down the Reset button and while holding it, turn on the power of the device. We hold it for 10-15 seconds, then release it.
Next, launch TFTP32.

In the Server Interface list, select the previously registered IP - 192.168.1.2 . Open the Tftp Client tab and enter in the “Host” field - 192.168.1.6 , and in the “Port” field - 69 . In the “Local File” field, use the “…” button to select the router firmware file. All that remains is to click on the “Put” button and wait until the software file is downloaded. To be sure, we wait another 10 minutes, after which we restart the device. We return automatic receipt of addresses in the network adapter settings and check access to QTech.

Note: If you can’t upload the firmware to 192.168.1.6, try doing it to 192.168.1.1. The fact is that for disaster recovery of a router on different version devices may use different IP addresses.

Don’t rush to throw away your broken router; perhaps, after some simple manipulations, it will serve you for many more years and save money on buying a new one. Moreover, if the cause of the device’s inoperability was a crashed firmware. This article will discuss a method for restoring firmware on D-LINK routers.

Instructions for flashing D-LINK router firmware:

For simple update To update your router’s firmware, download the firmware file with the extension *.bin from the official D-LINK website. We go to the router by entering 192.168.0.1 (in some models 192.168.1.1) into the address bar of any Internet browser. top panel menu, select the “MAINTENANCE” item, then in the left menu panel select “FILMWARE UPDATE”, then in the window that appears, find the “FIRMWARE UPGRADE” section, click “BROWSE”, indicate the path to the firmware file and click “UPDATE”. During the firmware, do not turn off, disconnect the network or press “RESET” power.

What to do if the firmware was not installed correctly?

What should you do if, for some reason, the power is turned off or the firmware is not installed correctly? There is a solution to this problem.

We begin to restore the inoperative router. To do this, we need to connect the router via a direct cable via the WAN port to the computer’s network card. Then go to the “START” menu => “Settings” => “Network connections” and select our connection to the router, right-click on it, in the pop-up menu click on “Properties”. In the window that appears, select the item “TCP/IP Internet Protocol” (in Windows 7 “TCP/IP Internet Protocol v4”) and click “PROPERTS”. In the “IP address” column enter 192.168.0.10, “Subnet mask” 255.255.255.0, “Default gateway” 192.168.0.1.

We return to the router, there is a “RESET” button on the back panel, with the power on, press it with any thin object for 10 seconds, then turn off the power, continuing to hold the button, wait 15 seconds, connect the power (hold the “RESET” button pressed) and wait until the power indicator on the router starts flashing, only after that release the “RESET” button (If suddenly the button is broken, you need to disassemble the router and close the 2 contacts suitable for the button).

Completing the firmware of the D-LINK router:

Open any browser and enter 192.168.0.1 in the address bar. Next we see a simple window with a line in which you need to specify the path to the firmware file that we downloaded earlier, and press the button to download the firmware to the router “UPDATE” or “SUBMIT”. There is no indicator that the firmware download is complete, so we wait about 2 minutes, then go to properties network connection=> “Internet Protocol TCP/IP” => “Properties” and put a check mark on the line “obtain an IP address automatically”, click OK. After that, go to the browser and enter 192.168.0.1 in the address bar (on some models 192.168.1.1). We have standard window to enter your login and password, enter login admin Leave the password field empty. The router is now ready for use.

Perhaps you needed to update your router software, but something went wrong. As a result, the output was a completely lifeless device: wireless connection does not work, there is no access to the router control panel through the browser address bar either. And the router operating mode lights either don’t light up at all or are clearly not working correctly. Even life-saving ones in the majority similar situations reboot or hardware reset all parameters to factory settings using the button RESET They don’t help out. Don't despair - you can still try to save the device.

All recommendations described below are relevant for the following Tr-Link routers:

TL-MR3220v2, TL-WR842ND, C7 AC1750 v2, TL-WR740Nv4, TL-WR941NDv5, TL-WDR4300ND, TL-WR1042ND, TL-WR940NDv2, TL-WR841NDv8, TL-WDR3600ND, TL-WR741NDv4, 3420v2.

If the desired model is not included in this list or you are afraid to carry out all the manipulations to restore the device yourself, then it is better in this case to contact specialists.

You can try to restore the devices listed above using special program, but, as a rule, it is possible to revive only those routers that were previously flashed with software with a recovery option.

If it is not possible to find out about all the previous manipulations, then the choice is yours: either, at your own peril and risk, still try to revive the router, or contact service center for help.

Preliminary data:

We will illustrate the recovery process with an example specific modelМR3220v2. Fully working device was deliberately flashed with third-party software to simulate a situation with a router ruined as a result of incorrect actions. To guarantee failure of the firmware process, the router was updated in wireless mode, and besides, his power was turned off before the upgrade process was completed.

Of course, there is no need to repeat these mistakes. Follow all the instructions and you will probably succeed.

In this article, we will begin to try to revive a non-working router, which, of all signs of life, has only two burning lights.

Nothing else can be done with it. Hard reset doesn't help either.

Before starting measures to save the router, you can try the following:

• Possible solutions to the problem can be found in the article What to do if you can’t access the router settings. After all, it is possible that everything is fine with the device, but the reason lies in something else.
• Can you do it again? different ways try resetting all parameters to .

Router recovery procedure

1. First of all we need specialized program recovery Тftрd. The archive with this utility can be found at this link - for firmware. Pre-create it in a convenient place on your computer new folder and unpack all the files from the downloaded archive into it.

1. Then you need to find the appropriate software to flash the router firmware. Official versions are located on the Tr-Link website. You can, of course, find different firmware on various file hosting services, torrent trackers, etc., but in this case, no one can guarantee you success and all actions to update the software are done at your own peril and risk.

In the list of available firmware software on the official website, find the files for your router version and your software version. Please note that the name of the firmware file did not contain the word boot. Details and nuances for finding files for firmware can be found here.

One more thing - unfortunately, when choosing a file to download, it is not possible to immediately understand whether the word boot is present or not. This can only be seen after the file has already been downloaded. Only by opening the archive can you see whether this word is in the title or not. You need to search in a file with the extension . bin.

The firmware needs to be unzipped and rename. The name must contain the model designation: "mr3220v2_tр_reсoverу.bin"(relevant for this router). Accordingly, for another model it will look similar.

After renaming the file, you need to move it to the same computer folder where the tftрd32.exe program is already located. The figure shows an approximate diagram of what should be the result:

1. Now you need to replace the IP address of the network connection. To do this, in the lower right corner of the desktop we find the Internet connection icon, click on it with the mouse and in the pop-up window click the inscription Network Control Center and shared access . In the panel that appears after this, select the item Change adapter settings.

Now you need to call context menu at the adapter "LAN connection" right click and press Properties.

Now select the line “Internet Protocol version TCP/IPv4” and after that you need to press Properties. Next action at this stage there will be an option selection "Use the following IP address".

Important point! The IP address that must be entered into the corresponding protocol properties field for different models routers will be different: for WR1042 and WR842 this value will be 192.168.1.66 . All other options correspond to the value IP address – 192.168.0.66 . (Alternatively, if both specified addresses will not work, you can try to register 192.168.0.86.) The subnet mask will be set independently - 255.255.255.0. In this option, save all changes by clicking the button OK.

The preliminary preparation process is complete. Now you can begin the main steps to restore the firmware.

1. Connect the router to the computer using the standard cable included in the kit. On the device, this is any of the four yellow connectors, and on a computer or laptop, this is the network card slot.
2. Now we go again to the computer folder where the firmware program files and the firmware itself are located. Select the tftрd32.exe file, then call up the context menu by right-clicking and select from the suggested options Run as administrator.
3. In the Tftрd flasher window that opens, in the line Server interface we find network adapter with the IP address set for this router in the previous step. After this, you need to look at the folder with the firmware, to do this, click Show Dir. Need to make sure that required file present.

If required firmware is in the folder, click Close. More on at this stage you don't need to do anything. We don’t close the flashing program itself yet.

1. Turn on the power of the router connected to the computer and quickly press and hold without releasing the WPS/RESET button on the rear panel, until the firmware update starts in the firmware program.

If there are any errors, you can try turning off the router and at first press and hold the WPS/RESET button, and only Then turn on the router.

You need to hold the button until full reboot devices: this can be judged by the blinking lights. This usually ends the software update process. The router should be restored to working condition. All other settings can already be made.

There are very detailed guide according to the firmware, it can be viewed here - detailed instructions according to the firmware of tr-link/ routers. You can.

After completing the software update process, do not forget to return the adapter properties to the option " Obtain an IP address automatically" See paragraph 3 this manual, if you forgot how to do it.

Conclusion

The process of restoring a router after unsuccessful firmware is simple if you do everything thoughtfully and slowly. As a rule, everything starts working properly after this.
