Note, that if you're flashing AirOS instead, at least the Bullet M5 series will remember setting between firmware upgrades and others may do so too. To reset username / password / ip address and other settings to factory default, first let the router boot, then press and hold the reset button until more lights come on and release. Wait for the factory reset to complete (a minute or two) and try to access 192.168.1.1 in a browser (ensure that your own IP is in the 192.168.1.x range). Note: This procedure seems to have no effect on the Bullet 2 HP, but works on the Bullet M5. It could be that the Bullet 2 HP does not persist settings across firmware upgrades, and so doesn't have the factory reset procedure. | Note, that if you're flashing AirOS instead, at least the Bullet M5 series will remember setting between firmware upgrades and others may do so too.

=Installing BATMAN= | |||
== Online == | |||
Use these instructions if your router is connected to the internet: | |||
ssh root@192.168.1.1 | |||
opkg update | |||
opkg install kmod-batman-adv | |||
== Manually / Offline == | |||
If your router does not have internet connectivity when installing, then use these instructions. | |||
Download these packages from: | |||
http://downloads.openwrt.org/<openwrt_version_name>/<openwrt_version_number>/<chipset_name>/<type>/packages | |||
As of 7/31/13, use this: http://downloads.openwrt.org/attitude_adjustment/12.09/atheros/generic/packages/kmod-batman-adv_3.3.8%2b2012.3.0-3_atheros.ipk | |||
Go to http://downloads.openwrt.org and browse to the correct directory. If there are multiple types, you probably want the 'generic' one, but check with the OpenWRT wiki page for your device to make sure. | |||
These are the required packages: | |||
kmod-batman-adv_<version>_<chipset>.ipk | |||
kmod-lib-crc16_<version>_<chipset>.ipk | |||
Use scp to copy them to the router: | |||
scp kmod-*.ipk root@192.168.1.1: | |||
Then ssh into the router and install them: | |||
ssh root@192.168.1.1 | |||
opkg install kmod-*.ipk | |||
=Configuring BATMAN= | |||
These notes are valid for OpenWrt 12.09 (Attitude Adjustment), which uses BATMAN 2012.4.0. In newer versions, the version of BATMAN used is 2013.0.0 and the syntax for configuring BATMAN differs slightly. See [http://www.open-mesh.org/projects/batman-adv/wiki/Batman-adv-openwrt-config this page on open-mesh.org] for more info. | |||
==Step One: Wireless Configuration == | |||
In /etc/config/wireless: | |||
<pre> | |||
config wifi-device 'radio0' | |||
option type 'mac80211' | |||
option hwmode '11g' | |||
option channel '3' # You may want another channel | |||
option disabled '0' | |||
option phy 'phy0' | |||
# the interface where non-mesh nodes connect | |||
config wifi-iface | |||
option device 'radio0' | |||
option ifname 'ap0' | |||
option encryption 'none' | |||
option network 'lan' | |||
option mode 'ap' | |||
option ssid 'sudomesh' # You should change the ssid to be unique for dev purposes | |||
# the mesh interface | |||
config wifi-iface | |||
option device 'radio0' | |||
option ifname 'adhoc0' | |||
option encryption 'none' | |||
option network 'mesh' | |||
option mode 'adhoc' | |||
option bssid 'CA:FE:C0:DE:F0:0D' # You should change this to be unique for development purposes, but for meshing this should be the same for all routers on the mesh | |||
option ssid 'sudomesh-backchannel' # You should change the ssid to be unique for development purposes, but for meshing this should be the same for all routers on the mesh | |||
</pre> | |||
Write some of this stuff down for reference later! You might need it! | |||
==Step Two: Network Configuration == | |||
In /etc/config/network: | |||
<pre> | |||
config interface 'loopback' | |||
option ifname 'lo' | |||
option proto 'static' | |||
option ipaddr '127.0.0.1' | |||
option netmask '255.0.0.0' | |||
# set up ethernet bridging between eth0 and bat0 | |||
# this means that packets can move between the ethernet port | |||
# and the wifi mesh | |||
config interface 'lan' | |||
option type 'bridge' | |||
option proto 'static' | |||
option ipaddr '10.42.10.11' # this should be a unique IP | |||
option netmask '255.255.0.0' | |||
option dns '208.67.222.222' | |||
option gateway '192.168.1.1' # an internet gateway, not sure how to deal with multiple gateways yet | |||
option ifname 'eth0 bat0' | |||
# the mesh interface | |||
config interface 'mesh' | |||
option ifname 'adhoc0' | |||
option proto 'none' | |||
option mtu '1528' | |||
</pre> | |||
==Step Three: BATMAN Configuration == | |||
In /etc/config/batman-adv: | |||
<pre> | |||
config mesh 'bat0' | |||
option interfaces 'adhoc0' # the interface for which to enable batman0 | |||
option 'aggregated_ogms' # no idea what this means | |||
option 'ap_isolation' # no idea what this means | |||
</pre> | |||
==Step Four: System Configuration == | |||
In /etc/config/system you can set hostname and timezone. This is not strictly necessary for BATMAN to work, but it should be set correctly. The below timezone is correct for the pacific U.S. timezone. The naming convention for hostnames is: <router-model-name>-<some-unique-name-you-choose> | |||
<pre> | |||
config system | |||
option hostname tl-wr703n-foo | |||
option timezone PST8PDT,M3.2.0,M11.1.0 | |||
</pre> | |||
You may also have to turn off dnsmasq. (someone else can chime in if this contradicts their working knowledge) | |||
<pre> | |||
/etc/init.d/dnsmasq disable | |||
</pre> | |||
==Step Five: Testing == | |||
You should see the 'sudomesh' and 'sudomesh-backchannel' wifi interfaces when running `sudo iwlist wlan0 scan` | |||
