-===== Installation =====+===== Supported Versions ===== 
 +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 [[doc:techref:bootloader]]! 
 +  * If there is a language-code. e.g. (DE)v1.0, that means, that the TP-Link WebUI is that language. (Of course [[doc:howto:LuCI#Native Language Support|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
-(One author review)I have only tried Backfire (10.03) on it, works quite well.

- * Upload it to ''/tmp''-directory on your router and execute:<code> + 
-mtd -r write /tmp/tplink.bin firmware+With the TL-WR842ND router, there is a catch: the stock firmware is obtained from the OEM: http://www.tplink.com/en/support/download/?model=TL-WR841N 
 + 
 +  * 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 V1.5 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: 
 +<code> 
 +dd if=orig.bin of=tplink.bin skip=257 bs=512
</code> </code>
-  * Be careful, if you were hit by the "missing web interface" problem described above, you will be probably see the same issue when flashing back to OEM and the box will lack in telnet or ssh, too, so no way to get out without hardware intervention.+ 
 +You should transfer the firmeware image to the /tmp folder and revert back to original firmware (if availlable you can flash the firmware via the webinterface as well): 
 + 
 +Via the safer method using sysupgrade: 
 +<code> 
 +sysupgrade /tmp/tplink.bin 
 +</code> 
 + 
 +Or you use the mtd method: 
 +<code> 
 +mtd -r write tplink.bin firmware 
 +</code> 
 + 
 +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).

 +=== Final actions ===
 +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.
 +
 +===== Use WPS with WPS button =====
 +// found info in Netgear WNDR3700 page  [[toh:netgear]] and adapted for WR841N //
 +
 +==== Prepare and install WPS ====
 +  - Follow the instructions for installing WPS : See [[doc:uci:wireless#wps.options]]
 +  - Your '/etc/config/wireless' file should be like that :
 +<code>
 +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'
 +</code>
 +==== Check configuration ====
 +  - After reboot, if everything is ok, you can test with this command:
 +<code>
 +root@OpenWrt /root# hostapd_cli -p /var/run/hostapd-phy0 wps_pbc
 +Selected interface 'wlan0'
 +OK
 +</code>
 +==== Plug button action ====
 +  - 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'
 +<code>
 +#!/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
 +</code>
 +If everything goes ok, you should see in Syslog not only the button events, but also succesful WPS authentication.
