 +==== Recovery (v2) ====
 +
 +Using the integrated tftp capability of the router.\\
 +
 +First, enter failsafe mode:\\
 +
 +Remove the power plug from the router.\\
 +Press and hold the WPS/RESET button.\\
 +Insert the power plug without releasing the RESET button, wait a moment for the Lock LED to come on solid.\\
 +Release the RESET button\\
 +
 +Connect pc to one of the router LAN ports.
 +
 +^Device ^IP|
 +|router ip|192.168.0.86|
 +|set your pc ip|192.168.0.66|
 +
 +Set pc ip:
 +<WRAP prewrap 100%><code>
 +ifconfig eth0:1 192.168.0.66/24 up
 +</code></WRAP>
 +
 +Router repeatedly tries to download ''wr842ndv2_tp_recovery.bin'' from a tftpd server running on 192.168.0.66.\\
 +
 +Install tftpd server:
 +<WRAP prewrap 100%><code>
 +pacman -S tftp-hpa
 +</code></WRAP>
 +
 +Download TP-LINK firmware to tftp root and rename it to ''wr842ndv2_tp_recovery.bin'':
 +<WRAP prewrap 100%><code>
 +mkdir /srv/tftpd
 +cd /srv/tftpd
 +wget http://www.tp-link.com/resources/software/TL-WR842ND_V2_130628.zip
 +unzip TL-WR842ND_V2_*.zip
 +mv wr842ndv2_en_3_14_2_up_boot(130628).bin wr842ndv2_tp_recovery.bin
 +</code></WRAP>
 +
 +Start tftpd server:
 +<WRAP prewrap 100%><code>
 +systemctl start tftpd.socket
 +systemctl start tftpd.srvice
 +</code></WRAP>
 +
 +Router must in recovery mode **before** starting tftpd server, otherwise it might have problems trying to bind to the PC network interface.\\
 +
 +After some time you will see all LEDs flashing once followed by a normal restart of the router.\\
