My goal is to be able to access multiple Raspberry Pi Zero Ws (3-5) simultaneously through SSH from a laptop running Linux. This has to be done in an area where there is no infrastructure network available (out in a field in the middle of nowhere), and it has to be done wirelessly. I have, so far, been unsuccessful in accessing even one RPi through SSH with my laptop. I have not been able to create a network connection between the two devices. I have tried creating an ad-hoc network on the laptop using the following forum pages and tutorials, to name a few:
Setting up a Raspberry Pi as an access point in a standalone network
Wireless Communication Between Raspberry Pi and Your Computer - this worked, but the laptop connects to a network created on the Pi, and I need the opposite so that multiple Pis can connect to the 'central' laptop
I am a true beginner. Touched Linux and a Raspberry Pi for the first time last Monday (June 5, 2017). I have spent almost all of my time at work trying to figure this out with no success.
What is the simplest way to simultaneously control multiple RPis (with fresh installs of Raspian Jessie) using a laptop with Linux (Ubuntu)? Remember, there is no infrastructure network where I'll be doing this.
Please let me know if there's other information that I can provide to help.
