Restoring TP-Link routers via serial interface

It will not be possible to restore a D-Link router after unsuccessful firmware using simple and understandable methods for any beginner. The manufacturer did not provide any proprietary application, such as the one, with which you could revive the router in a couple of clicks. But don’t be upset, now I’ll show you everything clearly and I’m sure that you will succeed too. We will do this through the command line - this method is suitable for any D-Link models - DIR-300, DIR-615, DIR-2640u and others.

How to restore a D-Link router via Emergency Room?

For D-Link router recovery You will need the current version of the software, or, to put it simply, firmware. About how to download it.

So let's get started.

Now we launch the Windows command line as an administrator. In Windows 10 it is called as “Search - CMD”

On Windows 7 - "Start (Right Click) - Command Prompt"

Enter the command

ping 192.168.0.1 –t

You need to wait until the response from the router is positive, and then type http://192.168.0.1 in the browser. The Emergency Room page will open.

Here we click on the “Open” button, select the firmware file that we previously saved on the computer, and then click on “Upload”.

After a few minutes, the D-Link router will be restored and can be configured from scratch.

Backup D-Link settings

Well, if you took care of saving a copy of your router’s configuration in advance, then you don’t need to configure anything - you just need to restore them from a backup.

In the D-Link admin panel, at first glance you can confuse several items according to their purpose. After, to restore the settings of the D-Link router after the firmware, we need to go to “System - Configuration”. To create a backup version of the settings, click on the “Backup copy” button opposite the inscription “Save the current configuration to a file.”

To restore, select the file in the “Loading a previously saved configuration to the device” item

Hello! In this article we will take a detailed look at restoring a Tp-Link router after unsuccessful firmware. It often happens that during the router's firmware some kind of failure occurs, and the router simply stops working: Wi-Fi does not work, the power indicators do not light up as usual, it is impossible to enter the router settings, etc. In such cases, even reboot and reset settings to factory settings. If you unsuccessfully flashed your Tp-Link router and it looks like a brick, then you can try to restore it.

This method can restore the following Tp-Link models:

TL-MR3220v2, TL-WR842ND, Archer C7 AC1750 v2, TL-WR740Nv4, TL-WR941NDv5, TL-WDR4300ND, TL-WR1042ND, TL-WR940NDv2, TL-WR841NDv8, TL-WDR3600ND, TL-WR741NDv4, 3420v2, TL -WR940N V2

If your router is not on the list, then most likely it can only be restored with a soldering iron and a special cable. In this case, it is better to contact the service center.

All the models that I have listed can be restored programmatically, which is what we will do now. True, you can bring back to life those devices that were last flashed with special firmware with recovery support. But you don’t need to delve into it, it’s easier to try.

Patient:

I thought it would be wrong to prepare instructions without checking everything myself. Therefore, I took my Tp-Link TL-MR3220v2 router (I don't use it now), which, in principle, is fully working, but for some reason it point-blank refuses to see any 3G modem. Well, for the purity of the experiment, I decided to turn it into a brick. This is not very easy to do (when necessary :)). First, I tried to upload the firmware for a different hardware version, it didn’t work, it gave me an error. Then, I decided to flash it via Wi-Fi - it was flashed. Well, I had no choice but to turn off the power during the firmware update :) Never do that! After all, it may not be possible to restore it.

It turned out that I have a non-working Tp-Link TL-MR3220v2, which only has two indicators (power and gear).

It did not respond to resetting the settings, and of course it was impossible to enter the settings.

You can try before starting to restore the router:

• See the article with possible reasons why. Perhaps you have some other problem, but the router is working.
• Before restoring your Tp-Link, try.

Tp-Link router recovery process

1. First of all, we need to download a special program Tftpd. You can download it from this link - (size - 467 kb). Save the archive with the program on your computer. Create a folder with any name. I created it on the desktop, named "325". Extract the program itself, the file, to this folder tftpd32.exe.

2. Next, we need to download special firmware. You can download this firmware from the official Tp-Link website. Find the firmware for your model and hardware version - this is important! And one more important point, The firmware name should not contain the word boot. If you don’t know where and how to look for firmware, then look at the article.

In the name of the firmware on the website, you will not see the word boot. Whether the firmware is suitable or not can only be seen by downloading it to your computer and opening the archive. See the name of the .bin file itself, which is located in the archive. For my TL-MR3220v2, I downloaded the first firmware on the list (on the website), and it worked.

Extract the firmware file from the archive and rename it. The name should be like this: "mr3220v2_tp_recovery.bin"- this is for the TL-MR3220v2 model. For example, for TL-WR841ND v8 the name will be: "wr841ndv8_tp_recovery.bin". It all depends on what model you have.

Then place the firmware file in the folder with the tftpd32.exe program. You should get something like this:

3. You need to change the IP address of your local network connection. Right-click on the Internet connection icon and select Network and Sharing Center. In the new window, on the left click on Change adapter settings.

Right click on the adapter "LAN connection" and select Properties. Next, select the item "Internet Protocol version TCP/IPv4" and press the button Properties. Place the switch near "Use the following IP address".

Now attention! For router models TL-WR1042 and TL-WR842 V1, write in the IP address field 192.168.1.66 . For all other models, write - 192.168.0.66 . (If both addresses do not work, try 192.168.0.86.) The subnet mask should be registered automatically - 255.255.255.0. Let's leave her. Press the button Ok.

Preparations are complete, let's begin.

Disable your antivirus, firewall, and other programs that may be blocking the connection.

dr.web asked me for permission for the program.

4. Connect your router to your computer via a network cable. On the router, the cable can be connected to one of 4 LAN connectors.

5. Open the folder in which we put the firmware and program. Run the tftpd32.exe program as an administrator. Right-click on it and select Run as administrator.

6. In the Tftpd program, on the contrary Server interface select the required adapter. There will be an IP that we specified above. Next, click on the button Show Dir, and see if our firmware is on the list. In my case it is "mr3220v2_tp_recovery.bin".

If everything is fine, then the program is simple leave it open. You don't need to press anything to start recovery.

7. We take our router (which should already be connected to the computer), turn on the power, and quickly press and hold the WPS/RESET key.

We hold it until the recovery process begins in the program. Everything worked out for me right away. If it doesn’t work, try this: turn off the router’s power, press and hold the WPS/RESET key and turn on the power.

We wait and don’t press anything until the router reboots. You will understand this by the indicators. My router started working and I had no problems.

If you want, you can flash the router using the usual method according to these instructions -. Just look carefully :) well, you’ll have to configure the router. You can.

In the properties of Local Area Connection, do not forget to set it back Obtain an IP address automatically. We changed it in paragraph 3 of this article. Otherwise, there may be problems connecting to the Internet via cable.

Conclusion

As you can see, everything works. It was possible to restore a router that many would have simply thrown away, or would have had a bunch of problems with the warranty service center. Few people take routers for repairs. People usually think it's easier to buy a new one (in some cases, this is true).

Don't forget to write in the comments about the results, it's important! Especially if you managed to restore a Tp-Link router model that is not listed at the beginning of this article. Any information on the topic will be very useful!

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:

To easily update the firmware of your router, download the firmware file with the *.bin extension from the official D-LINK website. We go to the router by entering 192.168.0.1 into the address bar of any Internet browser (in some models 192.168.1.1), in the top menu bar select the “MAINTENANCE” item, then in the left menu panel select “FILMWARE UPDATE” then in the window that appears we find the “FIRMWARE” section UPGRADE", click "BROWSE", specify 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 work on 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 for about 2 minutes, then go to the network connection properties => “TCP/IP Internet Protocol” => “PROPERTS” 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 a standard window for entering login and password, enter login admin and leave the password field empty. The router is now ready for use.

In this article we will tell you how to restore your router D-Link after unsuccessful firmware.
How to restore factory firmware D-Link after an alternative, like DD-WRT, OpenWRT, Wive-NG and others.
And also how to return the router to working condition after the D-Link firmware has crashed.

The method is proven and working.
The D-Link DIR-300NRU B1 will serve as our test subject.

So, here we go:

1. If the router does not show any signs of life, or only the orange diode is on "power", then first of all we remove all the cords from the router, including the power supply.

2. Download from

Attention! You do not have permission to view hidden text.

Firmware, file .bin from the folder DIR-300NRU/FIRMWARE/B1_B2_B3 strictly for our router and save it, for example, directly to drive C:

3. Go to the network card settings and protocol properties TCP/IPv4 we register IP address 192.168.0.10 mask 255.255.255.0

4. Next, we connect the network card of our computer with a wire to one of the LAN ports of the router, let it be LAN1.
(To return the factory firmware of the DIR-100, you need to connect the computer’s network card to the WAN port of the router ( internet ).

We indicate the location of the previously downloaded firmware strictly for Dir-100 and follow the link fla .

5. Off press the button RESET(match or other stupid object) and, holding it, connect the power to the router

6. Without letting go, hold down the RESET button (20 seconds) and wait until the router’s emergency recovery mode loads.

7. In the browser Mozilla or Opera(not IE only) type the address 192.168.0.1 And lower the RESET button.

8. We indicate where the firmware is located (where we downloaded it) and click Upload firmware now .
Next, wait until the update is completed

9. If everything is done correctly, then after completion we will see the authorization window for our D-Link/
Login and password will return to default admin/empty

After restoring the firmware, do not forget to return the settings of the computer’s network card. Set to obtain IP address and DNS automatically.

If it doesn’t work out the first time, then try to carry out this procedure with another browser; it often happens, for example, it doesn’t work through Opera, but everything goes well through Mozilla Firefox, or vice versa.
You can also try to “flash” the router with an earlier firmware with FTP D-Link, the earlier firmware is in the folder DIR-300NRU/FIRMWARE/B1_B2_B3/old.

After such simple manipulations, you can restore the factory D-Link firmware after a failure, unsuccessful firmware, or after firmware from third-party manufacturers.
