Once upon a time I bought this device and did not know grief. But a month ago, the devil pulled me to update the firmware, as nod32 cursed the vulnerabilities of the official firmware.
I downloaded the updated official firmware, uploaded to the router, he reported on the download-installation and warned about the upcoming reboot. I left to smoke at that moment (smoking harms your health), and when I returned I saw the picture: the router's web-interface restarts ~ 3 times per second and still reports the upcoming reboot. The poor man was sent to reboot through the button, but moreGulchitaydid not show me the web interface.
I sat down to understand, tried to restore through the "Restore" button according to the instructions from the official site, but nothing happened. As it turned out later, the device still pinged, but only 4 packets come in response.
I purchased a usb-uart adapter and decided to sew. But, Google did not give anything about the speed (115200) of connecting ttl, or about further manipulations with this particular model of the router. At the moment, using the spear method, I managed to connect to the router via Putty. In the screenshot is my last checkpoint.
Hence the question: what to do next? Be kind, tell me, eh?

Further more. I will try to streamline all my actions from beginning to end, for a greater understanding on your part of what I did and how I did.

I set the computer IP: 192.168.1.10 and Mask: 255.255.255.0
In the PuTTy category, Session, chose the type of connection Serial, prescribed "COM3" and the speed "115200". Poked on the "Open" button.
The console opened, turned on the router and stopped the automatic loading with any key:

* qwestery,I set up OpenWRT for myself, two or three years ago, after I read the instructions on that site for the firmware in Russian, which eventually banged the router. xD
If it does not matter what firmware to use, onOpenwrtwritten instructions on how to flash through tftp, using the UART, but it is in English. Just there nothing was written about "erase / here should be the address of the flash-memory /". When flashing, the router itself re-recorded the sectors. I myself stitched the device on ubunt, usingthisarticle to the table of contents "Running minicom". The only caveat, I do not remember how, after recovery via the console, set up some file in the file system of the router so that the web interface could load. Maybe in the latest firmware fixed this bug, lol. In any case, good luck. : happy:

I downloaded the updated official firmware, uploaded to the router

And what about the firmware version so nakosyachila?
I wanted to update myself, but now I will see ...

By the way, d-link routers have a so-called. crash load
Pressing and holding the RESET button for a long time while turning on the router.
At the same time, the router climbs onto the USB flash drive connector for the firmware, and having found it, floods it into itself.
You can try this method.

* davydoff2004,
I don't really want openwrt. I'm still closer native firmware)

* lerron,
Nakosyachila "Actual" version 1.0.1.102. I was able to restore the router and tried to flash again on the last official one. And again the ill-fated Kernel-panic. I wonder how many people have blurted out their routers with this firmware.
A little later I’m telling the instructions. No dancing with a tambourine, only the ttl adapter is needed))

Instructions for those who did not help recovery via button and tftp
In order to restore the wnr2200, it is necessary:
  1. USB-UART / USB-TTL adapter
  2. Attached fileputty-64bit-0.70-installer.msi(2.91 MB)

  3. Attached fileTftpd64_SE-4.62-setup.exe(621.95 KB)

  4. Firmware file (upload to TFTP folder)
  5. Two arms
  6. twisted pair


We disassemble the router and look for contacts UART
Attached Image

The one that is marked with a dot is food. We do not touch him.
router - adapter.
1.GND-GND
2.

RXD-TXD download


3.Txd-RXD
4. 3.3V
We connect the USB-UART adapter to the computer.
We connect the router to the computer with a twisted pair on the LAN (I connected to the next after the yellow one)
Launch PuTTy and configure it immediately:
Port number expose your.
Attached Image

Click onOpenand the terminal will open. Now you need to turn on the router from the button.
The router starts loading and at some point asks:
any key to stop autoboot
Well, you know what to do.
I had to set up a PuTTy ip router (setenv ipaddr) and a computer (setenv serverip). Since the router did not go up DHCP.
If you have the same, then on the computer we set IP: 192.168.1.10 and mask: 255.255.255.0
In PuTTy:
setenv ipaddr 192.168.1.111
setenv serverip 192.168.1.10

Run TFTP and configure:
Attached Image

Now go back to PuTTy and write:
tftpboot

The router will answer that there is no firmware file with the correct name. Example: 6F01A8C0.img
Copy the name that it needs from the terminal and rename the firmware file. Entertftpbootagain.
Must go through a small download.
After the router finishes loading, we write:
bootm

Go to TFTP and set the host address 192.168.1.1, press the buttonPut
Routerbegan to flash and out of his powerno need to turn off.
After a minute, you can go to routerlogin.net and log in with your username / password.
Everything

Firmware file (upload to TFTP folder)

So which firmware version is flooded this way?
And does it work well?
I was just on the site alarmed that the previous one has a higher version (1.0.2.24) than the "Actual" version 1.0.1.102
I decided to search this forum and found it ...
For the info plus.
By the way, for those who will do the procedure from a “native” PC or by using a USB-Serial cord, you need to add that the TTL level is on the router board.
That is, refinement is needed. Description here -https://habr.com/en/post/369467/.

andAttached fileopenwrt-06.06.1-ar71xx-generic-wnr2200-squashfs-factory.img(3.63 MB)
Both rose. At first I tried OpenWRT, then 1.0.2.24 was a normal one. It remained on it, it works as it should.
Interestingly, the old settings for 1.0.2.24 are preserved in the router.

If it does not complicate, I would ask you to measure the speed of reading from the flash in the USB connector.
And then the main router (DIR-825) is painfully bad in this part ...
Thank you in advance!

* bitsmoook,
Logically, this instruction should help:
1. We connect the router to the computer, to slot 1 - the one that is black, NOT YELLOW.
In the network interface settings, we assign our PC a static IP
IP address 192.168.1.2
Subnet Mask 255.255.255.0
Press the "OK" button

2. It is necessary to activate the TFTP client with which the firmware will be downloaded to the router: Start-up>Control Panel->Programs and components->Enable or disable Windows components. Check the TFTP Client and OK.

3. It is necessary to put the router into recovery mode, for this we turn it off with the button (located at the bottom of the router) Restore Factory Settings. Gently press this button and turn on the router, the Restore button, while continuing to hold for at least 45 seconds, after that the router goes into recovery mode. A sign that the router is in this mode - the LED indicating the power status starts flashing. After that, you can release the reset button and return to our PC.

4. The firmware file is moved to the root of drive C.
Open the command line (Win-button with the Windows logo and the 'R' key, register cmd) and in the opened command window, type:
tftp -i 192.168.1.1 put C: \ wnr2200-100-V1.0.2.12.img
and press the Enter button.
The system will think a little and after that will issue:
Successful transfer and number of bytes ...

Or use TFTP Server:
Throw the firmware file into the folder with the TFTP Server
Select the server address 192.168.1.2 (your network device)
We write the address of a host (router) 192.168.1.1
Select the firmware file, press the Put button

5. After that, it remains to wait, the router will flash all the LEDs. We are waiting for the moment when the diodes: Power, wi-fi and network connectors will glow green. It will take about 2 minutes.

Do not turn off or restart the router during its flashing!
After that, go to the WEB interface, at: 192.168.1.1 or routerlogin.net
Login and password are standard: admin; password

Hello, please tell me whether you can configure this unit to receive Wi-Fi. I found information on other manufacturers, but I could not.

Help me to restore this brick :(. Fortunately, I have bought usb for a long time and waiting in the wings for usb ttl. My hands are also straight .. But he doesn’t want to be sewn (I do as described. I catch lace 1 - black, 2 - white 3 - green, I don’t cling to power. I open putty. I adjust the port and speed, press open. The terminal opens and here I’m plugging. When he writes "any key to stop autobot", I press any key and this is what happens: 1 - the router does not see that I pressed something and continues to boot into the console, 2 - the keystroke is perceived, the text in the console stops, but when I try write any command, sort out some special characters instead of letters ...
