Topic: TP-Link TL-WR941N WR941ND - Atheros AP81 platform, USB port

The content of this topic has been archived between 13 Jun 2015 and 6 May 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

sergejk, yes this firmware will work. I did it from the original firmware page and it works fine. You can also go back to the original firmware using the LUCI web page.

thanks for info ... how long do you have it ... did you have problems with internet connection drops with that firmware?

Brgds,
S.

You should compile your own image using the latest trunk to get stability and good throughput.

I have my 941ND v4.1 working with USB. If anyone is still interested I can post some details.

Great!

will you share the detail? I just startup a 941n basic system today, I have all things flash programmer/usb connector/solder/dc converter/resistors... for the usb.

WR941ND V4.1 to get USB operational.

Excuse the quality of these instructions as this is the first informative post I have made.

You will need to make both hardware and software changes. This was worked out (fallen upon?) after reading many postings on both open-wrt, dd-wrt and elsewhere. Thank you to the many people who have contributed to the discussions on this router and especially to Kartman for his handy work with his soldering iron.

On the kernel side you need to make the change as stipulated by Mausi in
http://forum.openwrt.org/viewtopic.php? … 64#p104964
and build the image. I am using 10.03. See the wiki for instructions on how to build for the 941.

If you want to boot from a USB stick you will want to link the usb and usb-storage into the kernel. I recommend you do it initialy with loadable modules first till everything is working as you want it. You will need to use the ohci driver for this hardware version.

You shouldn't need a flash programmer unless something goes really wrong. The worst I had while experimenting was loading from uboot for which I used:
loady 0x80800000 115200
erase 0x9f020000 +0x3C0000
cp.b 0x80800000 0x9f020000 0x3C0000
Again see the wiki for information on how to get into uboot on the 941

On the hardware side we (mostly Kartman) started off just getting the usb working without giving it power and running a small powered hub off the port. We then added power to the port. The regulator used is not an overly cheap one but it was something that was on hand.

http://img829.imageshack.us/img829/3403/wr941ndv41side2.th.jpg

The pulldown resistors were placed on the underside of the board as there was more space to work with.

I have successfully run a memory stick, ftdi usb-to-serial and 2 logitech C120 webcams in parallel.

My current project is to get pivot-root working so that I can load modules from the usb stick.

hello, anybody can tell me some info about C483 element on this board(WR941ND rev3.4) ?

I have just found this community and flashed my TP-LINK TL-WR941ND with "openwrt-ar71xx-tl-wr941nd-v2-squashfs-factory.bin": All went smoothly, but I am new to these things and I was trying to configure WAN port and then LAN ports I set DHCP and applied changes, but since then I was disconnected from the router and now I cannot access anymore the router. I tried resseting with reset button but doesn't work. Is it bricked now or what happened to router?

I need to setup internet with PPPoE, change MAC address of the WAN port and change TTL because my ISP is using TTL 129 for their network packets. Is there somebody to help me setup router this way?

Thanks in advance

Serial console.

Yes I am struggling with it. I know the pinout now but didn't found somewhere a completed tutorial that works 100 %. I read somewhere that I can make the serial cable from CA-42 Nokia cable and also I read that I should flash via U-Boot, but U-boot is just for Linux machines and I don't have here Linux machines. Can I use any other tool to flash via serial console? Can I use Hyperterminal from Windows? Or any complete tutorial/ I need to unbrick this device.

Thanks

You can load firmware from uboot using any app capable of Ymodem, etc. It doesn't matter what OS you're comming from.

I am using a Nokia cable.

Once you get your serial console happening you should not have any trouble flashing it back to life. What hardware revision do you have?

Can anybody assist me in recovering my router? I am struggling to revive it without compromise. I have made some interesting connections as you can see from the photos at the links below:

http://i662.photobucket.com/albums/uu34 … C01989.jpg
http://i662.photobucket.com/albums/uu34 … C01991.jpg

I have connected R356 by just sliding the glue there with a screwdriver till it gets connected, and I test with multimeter continuity, For serial connection I have used a mobile phone box that I have "InfinityBOX, but I can use any other boxes that I have among Infinity and it works charmantly. And for serial pins connections look at the picture how I did. I use those pins for some mobile phones unlocking when I don't have the cable and connect the pins to TX, RX and GND, so I thought that even for this router this type of connection should work and yes it works, but the interesting thing is that I have not glued even TX, RX and GND pins, because the GND pin was a little hole so that I just  leave it there and TX and RX I pushed with force and now they have made a little holes and are standing there without me holding them.

after trying to return from OpenWRT to Original firmware, and now I am trying your procedure to revive my router but it is not working. I need just to recover it with Openwrt or original firmware no matter. It seems that I need to write original firmware with Boot like this firmware image: wr941nv2_v3_en_3_11_2_up_boot(100323).bin, because the boot is corrupted when I tried to revert from OpenWRT to Original Firmware. Can anybody assis me with proper flash addresses that I should give to U-Boot for this firmware that has the size of 3.87 MB (4.063.744 bytes). I don't want to kill completely this router.

Thanks in advance

Any Ideas? Maybe a tricky u-boot parameter. Or a possibility to flash via u-boot?

Hi,
I took another brandnew TL-WR941ND router and flashed to it DD-WRT not the openwrt like in another router and I go to change some WAN settings and then restarted it, settings are saved successfully but now everything that I change and then reboot router no settings are saved any more. It seems that I have the problematic routers, but although somebody reported that they have Intel flash, my routers have Winbond flash not Intel. Now I am trying to revive my first router with TFTP flash but don't know the exact procedure or it seems that it is not saving even firmware. How can I debrick these routers? Can somebody provide me with commands to erase and then write an original firmware to these routers.

On the second router that I put today dd-wrt on it , I am trying to revert with files provided by Brainslayer but they are not working at all.

Thanks

Hi erreterr

From the photos you posted you look like you have the same hardware revision.

I used the following commands to revive my router from a bad flash:

Using the serial terminal, type in tpl at the 1 second wait on boot up. (from the look of your post you have already been able to achieve this)

Once at the Uboot prompt you can type..
loady 0x80800000 115200

Use a terminal program to send the factory bin file via ymodem (remember 115200 baud) this is a very slow process. Go make a coffee, drink it, then go and make a couple more. Once you have finished those drink some tea as it's not good for you to drink so much coffee. Hell, go watch a movie.

Once it has finally finished go back to the console and type
erase 0x9f02000 +0x3c0000
then...
cp.b 0x80800000 0x9f020000 0x3C0000

My recollection is that all was sweet after that.

If your hardware is something other that V4, then you MAY need to change some of the values.

Can you clear me which is that terminal program to send the file?
Thanks

Hyperterminal or Tera term will do the job

Hi Philth
Thanks for your advices. I sent now the file and go to the command  erase 0x9f02000 +0x3c0000 but I  get:

ar7100> erase 0x9f02000 +0x3c0000
Error: end address (0x0a2c1fff) not in flash!
Bad address format

I have v3.2 of TL-WR941ND

It seems that just the addreses are not correct because I don't need to send file via serial ymodem when I can send faster with tftp, but after I execute the commands to erase "erase 0x9f02000 +0x3c0000" and cp.b they are not working...

I had the same message using the Wiki instructions I changed the 0xbf020000 to 0x9f020000

http://wiki.openwrt.org/toh/tp-link/tl-wr941nd

The 0x3C0000 comes from the total size of the image that was written out.

Try with 0xbf020000 instead

If you can get the tftp working, great use it.

Strange...
Why I cannot recover my router using exactly the same method that you used.
It has entered into autorestart loop now and still didn't managed to recover it:
Autobooting in 1 seconds## Booting image at bf020000 ...
   Uncompressing Kernel Image ... Error: Bad gzipped data
GUNZIP ERROR - must RESET board to recover

Resetting...

On underneath I have version 3.2 and it has Intel Flash chip that doesn't save settings etc. I did an "erase all" into U-Boot and then followed exactly your steps, but still no success.

Thanks

Any Ideas? Maybe a tricky u-boot parameter. Or a possibility to flash via u-boot?

I managed to follow @fzfq3m in step 6 and now my router is accepting many types of firmwares, but not working correctly. I want to return to the original firmware because the openwrt and dd-wrt doesn't save any settings in my router

NAEOT, but check the binary you have is for V3 hardware, and if that is not the problem, it could be the address you're loading it to.

On the kernel side you need to make the change as stipulated by Mausi in
http://forum.openwrt.org/viewtopic.php? … 64#p104964
and build the image. I am using 10.03. See the wiki for instructions on how to build for the 941.

There is a correction needed to my earlier post. Mausi's instructions detailed a change to mach-tl-wr941nd.c, this is appropriate to V3 which he uses. V4 has a different processor, which is being treated like a WR741 as being evidenced by the following taken from my dmesg.

Kernel command line: rootfstype=squashfs,jffs2 noinitrd console=ttyS0,115200 board=TL-WR741ND

In performing a fresh build of openwrt I followed my own instructions without any luck, then remembered that the trick was to perform the identical change to mach-tl-wr741nd.c file.

I apologise to anyone who went down the wrong path due to this.

Try this but I'm not sure how to recover mtd "config'.
