Next your going to need the factory-to-dd-wrt.bin flash and to rename this to "wr841nv11_tp_recovery.bin"
Then set your machines network card to the ip address "192.168.0.66", default class C subnet mask "255.255.255.0" and the gateway to either nothing or "192.168.0.1"
Open the TFTP log window (so you can see when its connected and requested the file), if your under linux ensure your file ownership and permissions are correct.
For ubuntu you would use:
tail -f /var/log/syslog | grep tftpd
Now reboot the router buy holding down the reset button at the back, dont release keep holding and watching the TFTP server log and the moment you see the file request you can release the reset button.
Now wait patiently for the router to flash and reboot (normally around 2 ish minutes). After this reset your ip address to "192.168.1.66" so your in the right network range (or set to auto dhcp) and now you should be able to ping 192.168.1.1 Assuming you can, all is good you are now free from the stock firmware and dd-wrt is rocking strong.
I would advise doing a stock dd-wrt flash with the standard image (not factory-to version) and tell it to wipe the nvram (erase) before you do anything more. Just in case there is anything thats in nvram from the original firmware (not sure if ftfp flash also zeros it out fully so best to be safe).
Ive seen a few other people with the issue with firmware 160325 but no one that i could see had posted here, so forgive me if this is a double post.
A few remarks:
- When the router loads wr841nv11_tp_recovery.bin from tftp server and become accessible at 192.168.1.1 it is not flashed yet, even though dd-wrt web interface shows up, you still have to upload tl-wr841nd-webflash.bin within DD-WRT web interface (Administration->Firmware upgrade) and select "After flashing, reset to Default Settings"
- If you change settings and reset router without uploading tl-wr841nd-webflash.bin you will have to repeat the tftp procedure.
- I had to apply "lan port startup script fix" mentioned above, otherwise LAN computers didn't see each others.
Web interface: Administration->Commands
# Fix lan port communication 841 v7, v9, v11
swconfig dev eth0 set enable_vlan 1
swconfig dev eth0 set apply
and "Save as startup"
- The username and the password for telnet/ssh:
username:root password: whatever you set when first visiting web interface.

Thank you very much for this tutorial, I have this problem with my v11 model. But I can't figure out, how to configure the tftp server correctly, my router doesn't request anything and I also can't access it.
It would be very kind if one of you could make a video about this, that would probably help some others as well.
I have never flashed a router before. I've managed to set everything up on a Raspberry Pi to do it. I've got it set up on a static IP address with a TFTP server running and it's requesting the file. Unfortunately, according to wireshark, it doesn't seem to actually be getting the file.
It requests the file four times, from 192.168.0.86 which my TFTP server then responds by sending the first block back to that IP, four times. The router then gets confused and tells me the destination is unreachable.

I have followed the instructions for flashing the router via TFTP, and have setup my TFTP server for 192.168.0.66, but despite rebooting the router using the instructions, it never connects to the TFTP server. I have manually connected to it from another machine and can get the file without issue.
I have updated the firmware to the latest version on the TPLink site, but again so luck. Does anyone have any ideas how I might get the DDWRT software on there?????

The TFTP usually works without a problem but a few things to check. The TP Link software is looking for a specific file name so you might check the TP Link website and make sure you are renaming the file for your specific version. Also had an issue once where I was downloading from a computer to a flash drive onto another computer to upload to the router. Somewhere along the line the format was changing (probably because I had a player or something set as default and it was changing to something specific for that player) so make sure the name is correct and nothing else is changed.
I have problems with my phone when the router is with dd-wrt.
It constantly loses Wi-Fi, sometimes it doesn't want to connect, when it connects sometimes it says that Internet is unavailable and in the times that it works it works for a couple of minutes before it loses Internet again. My laptop however is connected over the same wireless and it's working with no problems.
Most of the time the phone is about a meter away from the router.
