The device is a wireless N router with

• 2 detachable antennas
• 4 Port 100/10 Switch
• 1 Port 100/10 Wan Interface
• 4 MB Flash
• 32 MB Ram
• WPS Button
• Wi-Fi On/Off Button

Note1: The TL-WR841N is identical except that the antennas are not detachable. TP-Link naming scheme is, that devices ending in a D have detachable antennas.
Note2: v5.2, v5.4 etc. are all v5, similarly for v7, v8, v9. The only difference is the firmware version they come with.

Known clones of this device:

• TP-Link TL-WR841ND v7: Rosewill Wireless N Router RNX-N300RT – see rnx-n300rt
• TP-Link TL-WR841N v8: ThinkPenguin TPE-NWIFIROUTER2 aka Rosewill RNX-N300RT v2 – see rnx-n300rt
• TP-Link TL-WR841ND v8: TP-Link TL-WR843ND v1, Mercury MW300R v3 and Fast FW300R v3.

The TP-Link versioning scheme seems to be:

• major-number.minor-number, where the major-number refers to hardware changes, and the minor-number refer to software (firmware) changes; this includes the bootloader!
• If there is a language-code. e.g. (DE)v1.0, that means, that the TP-Link WebUI is that language. (Of course LuCI has Native Language Support)
• Sometimes, version x. is only available in the PRC and version y. is intended for sale world-wide. The hardware between version x. and version y. can differ significantly but does not have to.
• Sometimes, there is Version x. for PRC only and Version x. for world-wide sale. If there is a special chinese-Version with the same major-number, then that version has usually significantly different hardware

The port indexes in OpenWrt and in hardware (on the case) are mangled (at least in Barrier Breaker):

eth0 is directly connected to the WAN port.

The port indexes in OpenWrt and in hardware (on the case) are swapped:

It is possible to run 802.1Q tags on these ports. As of Chaos Calmer mixed (tagged/untagged) VLANs are working, and can be configured via LUCI. The maximum VLAN number is 15

eth1 is directly connected to the WAN port.

• Flash the squashfs images only, the jffs images will brick the router (not enough space on 4Mb flash) (bug report).
• For DD(trunk) there is a change going on to remove the "N" and "ND"-suffix from the imagename (only "-tl-wr841-v10.bin").

1. Download image for your version.
2. Log in to router web interface and select the firmware image you just uploaded as an update.
3. Sit and wait while it flashes. It will reboot and be accessible at 192.168.1.1.

The Barrier Breaker image already includes a GUI, you do not have to install it manually.

Note: Newest version of tp link firmware (tested on TL-WR841N_V9_150310 / 3.16.9) does not accept openwrt firmware filename, because they are two long ; rename it to something < 64 chars, ending with .bin.

Warning! in some cases after reboot you don't have web interface (GUI), only telnet and ssh access. You can install GUI, for details see: luci.essentials, but before install LuCI (GUI) you need to configure your router to have access to internet, for configuration see: internet.connection

For v8,v9,v10,v11,v12 TFTP install is much easier

Beware that this installation method needs a TTL level serial console usb to TTL like DKU-5 data cable or RS232-TTL level shifter like this:
and a working TFTP server and should not be attempted unless you have experience with this sort of thing or are eager to learn.

This is taken more or less verbatim from https://forum.openwrt.org/viewtopic.php?id=24203, thanks to dl3daz.

1. Download an appropriate image to serve from your TFTP server (for example, openwrt-ar71xx-generic-tl-wr841n-v8-squashfs-factory.bin for v8).
2. Hook your routers WAN ethernet port up to your network (for v8.2 it's LAN1 ethernet port)
3. Hook up the serial console as explained in the section "serial console". At the prompt "Autobooting in 1 seconds" type "tpl" quickly to start a uboot console.
4. Now we need to set router and server IP addresses (here named ROUTERIP and SERVERIP, substitute these with the real IP addresses).

Type in the console:

setenv ipaddr ROUTERIP
setenv serverip SERVERIP
printenv

For example: Configure this static ip for your LAN card 192.168.1.100. If your computer containing other LAN or Wifi card, disable it!

Type in the console

setenv ipaddr 192.168.1.111
setenv serverip 192.168.1.100

1. Double check that the output of printenv lists the IP addresses you just set.
2. Uboot needs the tftp server to be listening on port 69. Make sure your server is configured to listen to that port. Now we can load the firmware over TFTP with "tftpboot 0x80000000 openwrt-ar71xx-generic-tl-wr841n-v8-squashfs-factory.bin":

   ar7240> tftpboot 0x80000000 openwrt-ar71xx-generic-tl-wr841n-v8-squashfs-factory.bin
   Using eth0 device
   TFTP from server 192.168.1.100; our IP address is 192.168.1.111

   Bytes transferred = 3932160 (3c0000 hex)

3. Note the "3c0000" in the last line (your number may differ). Now execute the following commands, if necessary replacing 3c0000 with the number you got from tftpboot

Type:

printenv bootcmd

Take note of the address and use it as flash erase start address.

For TL-WR841ND v3:

1. Erase the flash:

4. Done.

As most other current TP-Link routers this device can be flashed and debricked without serial access. Basically, the procedure is as follows:

1. Set your PC to use the static IP address 192.168.0.66 (the router will have 192.168.0.86)
2. Put an OpenWrt factory image named: for v8 mr3420v2_tp_recovery.bin or wr841nv8_tp_recovery.bin (for v8.4); for v9 wr841nv9_tp_recovery.bin; for v10 wr841nv10_tp_recovery.bin; for v11 and v12 wr841nv11_tp_recovery.bin in the root directory of an TFTP server and start it. For v12 you still need a v12 firmware. Just the filename has to be named as a v11 device!
3. Power on the router while pressing the reset button until the lock LED is lighting up
4. Wait for the router to reboot

WARNING! For hardware version 13, it is very likely that u-boot will be erased while using this method, as most mediatek SOC models tend to! Therefore, do NOT flash sysupgrade image using TFTP! Instead, follow the instructions described here: tftp_recovery_de-bricking for the factory image, for OpenWrt image, you must append the bootloader using dd. If the bootloader gets overwritten, the only way out is to use a SPI flash programmer to reflash it.

TFTP server log may contain info about firmware image name that router requested. Something like: Read request for file <wr841nv8_tp_recovery.bin> . Mode octet [21/11 09:45:27.574]

For details, see reset_button_method_no_serial_cable_needed

→ generic.uninstall

With the TL-WR842ND router, there is a catch: the stock firmware is obtained from the OEM: versions 1,5,7,8,9(versions v1 and v1.5 have same latest fw) and link for v3

• in case the file name of this firmware file does not contain the word "boot" in it, you can simply revert back to original firmware
• in case the file name of this firmware file does contain the word "boot" in it, you need to cut off parts of the image file before flashing it:

The following method applies both for the V1 V3 V5 V7 V8 and V9 since the bootloader is the same size.

An example of an image file with the word "boot" in it is wr841nv9_en_3_14_4_up_boot(131129).bin.

Cut the first 0x20200 (that is 131,584 = 257*512) Bytes from original firmware:

dd if=orig.bin of=tplink.bin skip=257 bs=512

You should transfer the firmware image to the /tmp folder and revert back to original firmware (if available you can flash the firmware via the webinterface as well):

Via the safer method using sysupgrade:

sysupgrade /tmp/tplink.bin

Or you use the mtd method:

mtd -r write tplink.bin firmware

It is also possible to revert to the stock firmware using the method with tftp described in "TFTP install". (you still need the firmware images without the boot part, unless you're using v13, in which case refer to the instructions for TFTP flashing above).

OEM TP-Link firmware for the TL-WR841ND with the boot part removed or the original firmware if there wasn't a boot part to revert to the original OEM firmware:

generic.failsafe

1. When the SYS led (under gear icon) starts to blink push the QSS/reset button for around 5-10 sec. Now the led should blink a lot faster than before.

1. Disconnect the router from the internet, connect it with a PC via RJ45 cable and perform a 30/30/30 restart
2. Change the ip on the PC to 192.168.1.2, subnet mask must be 255.255.255.0 and restart the router by unplugging the power cable
3. Perform a failsafe boot, quickly use

   telnet 192.168.1.1

If this didnt work check the ip adress on the PC or if you were too slow to connect during the failsafe mode. Still not working? Read this!

In telnet do the following things one after another:

• Define a password

  passwd

  enter

  yourpassword

  enter

  againyourpassword

  enter

• Kill the broken OWrt firmware

  mtd -r erase rootfs_data

  enter

  firstboot

  enter

  reboot -f

  After rebooting log in again just to check if the router is accessable. If you cant start again at the beginning.

Now change the network settings on the PC back to "Aquire IP adress automatically" and connect the router with the internet. Do a manual reboot by simply turning it off and back on again. The PC should now get an ip adress by DHCP. If this is the case you successfully resetted the router. If not repeat from the beginning or do this if you like.

Basically the router now works like after the initial flash to OWrt. Now you have to configure the internet connection and probably you want to install LUCI. After that open your browser, connect to 192.168.1.1 and log in with the data you entered via telnet.

configuration

Note: 30 dBm tx power can't be set if your wireless country is any that allow higher channel than channel 11 (i.e. Viet Nam). If you encounter this situation, I suggest you should change your country to 00 - World

1. First, install jow's reghack, follow those instructions (for ar71xx): http://luci.subsignal.org/~jow/reghack/README.txt

2. Flash this OpenWrt image with ART partition unlocked: https://goo.gl/InZONA

3. Download this hacked ART image: https://goo.gl/bz8oo1

4. Make a backup of your original ART:

dd if=/dev/mtd4 of=/tmp/orig_art.bin

5. Use SCP to transfer it to a safe place, then delete it from /tmp folder.

6. Transfer the hacked ART to the /tmp folder via SCP.

7. Run:

mtd -r write /tmp/artHACKED.bin art

8. Your router will reboot. After that, you will be able to set 30 dBm tx power.

Just be sure that the files are saved. To edit the files on windows, either use vi on the openwrt, check for a tutorial online, the basic commands are not difficult; or use winscp with a SCP connection and edit the files with an editor on windows. Then reboot the system and check for the wifi connection.

Remember that if the "client" wifi doesn't work, won't work also the repeater wifi network.

The default wireless configuration is different, for example there is no: option path 'platform/qca953x_wmac' . Further investigation shown that the wireless is able to provide an AP if connected to whatever interface defined in /etc/config/network, while for 'sta' mode (a wifi client) it is possible to obtain it only if the interface connected to the wireless configuration is not using the bridge option nor having a relation to a switch with more than one port (for example if with eth0 we define a switch over multiple ports) Note: would be better to check this statement more thoroughly.

For example, with the configuration reported above for barrier breaker, the wlan is linked with the wan side, that is using no switch interfaces nor bridge protocol. This works too for 12.09.

1. Follow the instructions for installing WPS : See wps.options
2. Your '/etc/config/wireless' file should be like that :

config wifi-iface
        option device 'radio0'
        option network 'lan'
        option mode 'ap'
        option ssid 'XXXXXXXXXXXXXXX'
        option key 'XXXXXXXXXXXXXXXXXXXXXXX'
        option wps_pushbutton '1'
        option wps_config 'push_button'
        option encryption 'psk2'

1. After reboot, if everything is ok, you can test with this command:

root@OpenWrt /root# hostapd_cli -p /var/run/hostapd-phy0 wps_pbc
Selected interface 'wlan0'
OK

1. Now, we can configure the WPS button on back on TL-WR841N to launch this command when we pressed it. Edit the file '/etc/hotplug.d/button/50-wps'

#!/bin/sh
# for debugging button name and action name, uncomment this 2 lines
#logger $BUTTON
#logger $ACTION

if [ "$ACTION" = "pressed" -a "$BUTTON" = "reset" ]; then
        for dir in /var/run/hostapd-*; do
                [ -d "$dir" ] || continue
                hostapd_cli -p "$dir" wps_pbc
        done
fi

Read this howto to use buttons on TP-Link

Found in WR741ND wiki page and coppied. It works on WR841ND too.

(Thanks to obsy) Wifi toggle by QSS button Simply create a new file called 01onoff in /etc/hotplug.d/button/

vi /etc/hotplug.d/button/01onoff

and copy these lines inside (remember to push 'i' for insert)

#!/bin/sh

[ "$BUTTON" = "wps" ] && [ "$ACTION" = "pressed" ] && {
 SW=$(uci get wireless.@wifi-device[0].disabled)
 [ $SW == '0' ] && uci set wireless.@wifi-device[0].disabled=1
 [ $SW == '0' ] || uci set wireless.@wifi-device[0].disabled=0
 wifi
}

Save and exit

Getting serial console is pretty standard fare. You need a MAX323 or similar level-shifter. The pinout on the router is RX - TX - GND - +5V (Power connector).

If you do not have serial port on your PC, use Nokia CA-42 data USB cable.

• For TP-Link WR841ND V7.0 the 10k the pullup resistor is not required, connect all four pins (tested with 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter, make sure to set its voltage to 3V not 5V)
• For TP-LINK WR841ND V7.2 power conector (+5V) is ignored, just connect RX - TX - GND and router power cord, work fine…
• My TP-LINK WR841ND V7.2 has a VCC of +3.3V and like the TL-MR3420 serial needed to connect a 10k pullup resistor between the TX and the 3.3V pin to get reliable serial:

• My TP-Link WR841ND V7.1 also requires the 10k pullup resistor between TX and the 3.3V pin. Without the resistor I just get garbage when I type, but can see some console output.
• just swap TX and GND pin in serial and no garbage in serial console, but this is read-only.
• For my TP-Link TL841N v9.0 i had to remove R26. It's a pull-up between RX (device side) and VCC. My ftdi device couldn't send data with R26 attached.
• For my Tp-Link TL841N V9.2 works fine without remove R26, Just normal TX,RX,GND connection works fine.
• For the TP-Link TL-WR841N v10: Seems to be the same PCB like the version v9. Serial works after remove R26, see v9.0. Tested with CH340G USB/serial device.
• For my TP-Link TL-WR841ND v8.4 was not required 10K resistor. My TTL to RS232 converter has bad marking of Tx and Rx pins. So, it was necessary to connect Tx-Tx and Rx-Rx. The connection of Vcc (3.3V) was necessary too. The connection scheme you can find on the following image:

Near the two biggest capacitor you could see a HE10 connector with 14 pin (V8).

For JTAG interface you need VCC. You could take it on the TP1 point test.

This violates regulatory requirements

Edit the file /etc/config/wireless

1. Below config 'wifi-device' 'radio0' add

   option 'noscan' '1'

2. option 'htmode' should be set either to HT40+ or HT40-(HT40+ wont work with Channel 11)

   option 'htmode' 'HT40+'

3. Restart wireless

   wifi

Check whether eth0/eth1 are switched! In failsafe mode, you have to connect to the wan port.

1. you could read about bootloader in general and about Das U-Boot in particular.

Forum member pepe2k made a modification of U-Boot 1.1.4 for Qualcomm Atheros SoCs based devices (the project is still being developed, so new devices and SoCs will be supported in the future). Up to date information, sources can be found on official GitHub repository and binary images here.

This modification started from wr703n-uboot-with-web-failsafe project, but supports more devices, all modern web browsers, has a lot of improvements and other modifications (like U-Boot NetConsole, custom commands, overclocking possibilities etc.).

More information:

• Official repository on GitHub: U-Boot 1.1.4 modification for routers
• Binary images
• Discussion about this project on OpenWrt forum
• An article (in Polish) about one of the first version of this project on www.tech-blog.pl

Tested on WR841n_v5.1

Attention. Firmware of TP-Link TL-MR 3420 is coming to WR841ND v7.2 - verified. (OpenWrt Firmware Attitude Adjustment (r28380) / LuCI Trunk (trunk+svn7612)) But working usb port has not been verified. Probably enough to use this firmware, but do not compile a new one :)

Overview of the board:

Soldering (wire with red accent means D+). R185 and R183 can be shorted then D+/D- will appear in J1.

To get working USB the new firmware build is required. Files to edit are listed below:

1. Edit file target/linux/ar71xx/files/arch/mips/ar71xx/mach-tl-wr841nd.c

    Add line #include "dev-usb.h" after line #include "dev-leds-gpio.h"
    Add line ar71xx_add_device_usb(); before line ar71xx_add_device_mdio(0x0);

2. Edit file target/linux/ar71xx/files/arch/mips/ar71xx/setup.c

   Add line ar71xx_pll_wr(0x08, 0x00001030); before line ar71xx_detect_mem_size();

3. Edit file target/linux/ar71xx/files/arch/mips/ar71xx/Kconfig:

config AR71XX_MACH_TL_WR841N_V1
        bool "TP-LINK TL-WR841N v1 support"
        select AR71XX_DEV_M25P80
        select AR71XX_DEV_PB42_PCI if PCI
        select AR71XX_DEV_DSA
        select AR71XX_DEV_GPIO_BUTTONS
        select AR71XX_DEV_LEDS_GPIO
        select AR71XX_DEV_USB
        default n

For newer version of trunk (as of 2013 March) 1.Edit file target/linux/ar71xx/files/arch/mips/ath79/mach-tl-wr841n.c

    Add line #include "dev-usb.h" after line #include "dev-leds-gpio.h"
    Add line ath79_register_usb(); after line ath79_register_eth(0);

2. Edit file target/linux/ar71xx/generic/profiles/tp-link.mk, add packages in the definition of TLWR841 as following.

define Profile/TLWR841
	NAME:=TP-LINK TL-WR841N/ND
	PACKAGES:=kmod-usb-core kmod-usb2 kmod-ledtrig-usbdev
endef

i.e L7805 with 470uF and 100uF can be used to obtain 5V from the stock power supply.

NOTE: in case of v5.1 sections for WR741N instead of WR841N_V1 have to be edited (Kconfig, mach-tl-wr741nd.c).

tested with WR841 v7.1 and trunk revision 30430. New patch for rev. 32461 available

Hardware mod is on pictures, nothing changed.

Kernel mod is different, because new kernel version is released in revision 30430.

Here is patch for kernel 3.3: http://mysicka.ics.muni.cz/openwrt/usb-patch-final.patch

Apply this patch and build…

I haven't tested this, but it appears to show where the USB D+ and D- pins can be found on the AR9341: http://ge.tt/m/2IKNi5l/
