After following the [[Mesh/WalkThrough]], you are probably just an isolated node on the virtual People's Open Network. If you want to become part of the physical mesh, you are going to need to extend the signal from home node using what we call an extender node. An extender node is just a roof-mounted, directional antenna used to make point-to-point connections between two locations that have line-of-sight (LOS) to one another. Preparing an extender node generally consists to two stages, downgrading the proprietary AirOS firmware and flashing it with our custom build of OpenWrt.
== Downgrading to earlier older AirOS ==
Typically, we use Ubiquiti equipment for our extender nodes. These come with a proprietary firmware called AirOS. Any extender node with version 5.6 of AirOS and above needs to be downgraded to a 5.5.XX version of AirOS version before you can flash it with OpenWRT.
* Network Manager Method: Manual
** IP Address: 192.168.1.10 (some devices will only accept from this IP)** Subnet Mask: 255.255.255.0** Gateway: 0.0.0.0 (Or leave blank)
You can also use the commands:
* Reconfigure your machine with the following static network configuration.
 ** IP address: 172.22.0.10 ** Subnet mask: 255.255.255.0** Gateway: 0.0.0.0
Or use the commands
Once configured with our firmware, an extender node will not start broadcasting an SSID until it is plugged into a home node because it must first get a mesh IP address.
If you have a mynet n600 or n750, you can get a mesh IP for your extender node by plugging the LAN cable that was plugged into your computer into to port one or two on the back of the home node.
The mesh IP that the extender node receives is the IP of the home node plus one or two. For example, if your home node broadcasts the SSID "peoplesopen.net 65.21.65" corresponding to the IP 100.65.21.65, then your extender node will receive either an IP or either 100.65.21.66 or 100.65.21.67. Once plugged into this home node, the extender node should broadcast the SSID "peoplesopen.net 65.21.66" or ".67" as well as the ad-hoc network, "pplsopen.net-node2-node" (you may not see these if your computer's WiFi antenna is only 2.4 GHz)
