Mesh networks are useful as a quick way to make a fully decentralised communications system which is not connected to or reliant upon the internet. Think festivals, hacker conferences, onboard ships at sea, disaster/war zones, small business internal office communications, protests, remote areas of the world, temporary "digital blackouts", scientific expeditions and off-world space colonies. The down side is that you can't access any internet content. The upside is that you can securely communicate with anyone on the local mesh. No ISPs. No payments or subscriptions beyond the cost of obtaining the hardware. Systems need to be within wifi range of each other for the mesh to be created. It can be an ultra-convenient way to do purely local communications.

In the instructions given below the <b>dd</b> command is used for writing to the target drive, but to write to multiple drives you can use a tool such as <a href="https://wiki.gnome.org/Apps/MultiWriter">GNOME MultiWriter</a>.

Routers are intended to build network coverage for an area using small and low cost hardware. You can bolt them to walls or leave them on window ledges. They don't have any user interface and their only job is to haul network traffic across the mesh and to enable peers to find each other via running bootstrap nodes for Tox and IPFS. Copy the image to a microSD card and insert it into the router, plug in an Atheros wifi dongle and power on. That should be all you need to do.

When that's done you should see a prompt asking for a username. This username just makes it easy for others to initially find you on the mesh and will appear in the list of users.

On the ordinary internet the date and time of your system would be set automatically via NTP. But this is not the internet and so you will need to manually ensure that your date and time settings are correct. You might need to periodically do this if your clock drifts. It's not essential that the time on your system be highly accurate, but if it drifts too far or goes back to epoch then things could become a little confusing in regard to the order of blog posts.
