  24       <div class="date">10th November 2013</div>
  25       <div class="body"><p>Continuing my research into mesh networking, I was recommended to
  26 use TP-Link 3040 and 3600 access points as mesh nodes, and the pair I
  27 bought arrived on Friday.  Here are my notes on how to set up the
  28 MR3040 as a mesh node using
  29 <a href="http://www.openwrt.org/">OpenWrt</a>.</p>
  30
  31 <p>I started by following the instructions on the OpenWRT wiki for
  32 <a href="http://wiki.openwrt.org/toh/tp-link/tl-mr3040">TL-MR3040</a>,
  33 and downloaded
  34 <a href="http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin">the
  35 recommended firmware image</a>
  36 (openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin) and
  37 uploaded it into the original web interface.  The flashing went fine,
  38 and the machine was available via telnet on the ethernet port.  After
  39 logging in and setting the root password, ssh was available and I
  40 could start to set it up as a batman-adv mesh node.</p>
  41
  42 <p>I started off by reading the instructions from
  43 <a href="http://wirelessafrica.meraka.org.za/wiki/index.php?title=Antoine's_Research">Wireless
  44 Africa</a>, which had quite a lot of useful information, but
  45 eventually I followed the recipe from the Open Mesh wiki for
  46 <a href="http://www.open-mesh.org/projects/batman-adv/wiki/Batman-adv-openwrt-config">using
  47 batman-adv on OpenWrt</a>.  A small snag was the fact that the
  48 <tt>opkg install kmod-batman-adv</tt> command did not work as it
  49 should.  The batman-adv kernel module would fail to load because its
  50 dependency crc16 was not already loaded.  I
  51 <a href="https://dev.openwrt.org/ticket/14452">reported the bug</a> to
  52 the openwrt project and hope it will be fixed soon.  But the problem
  53 only seem to affect initial testing of batman-adv, as configuration
  54 seem to work when booting from scratch.</p>
  55
  56 <p>The setup is done using files in /etc/config/.  I did not bridge
  57 the Ethernet and mesh interfaces this time, to be able to hook up the
  58 box on my local network and log into it for configuration updates.
  59 The following files were changed and look like this after modifying
  60 them:</p>
  61
  62 <p><tt>/etc/config/network</tt></p>

 140 <p>The mesh node is now operational.  I have yet to test its range,
 141 but I hope it is good.  I have not yet tested the TP-Link 3600 box
 142 still wrapped up in plastic.</p>
