I found a solution that worked quite well for me and might work for you! I've provided the steps listed below.
IMPORTANT: Upgrading the firmware WILL return your WiFi Pineapple to factory default settings, so if you have anything you wish to backup then NOW is the time! I'm not sure if the firmware upgrade was designed to do this but maybe the developer can modify the next firmware upgrade to keep previously saved files and configurations...
Follow the steps to install the latest sysupgrade (upgrade-2.2.0.bin):
1) SSH into the WiFi Pineapple using a terminal via user: root
Note. Internet connectivity is required to perform this step.
2) cd /tmp
3) Download the appropriate firmware file for your particular WiFi Pineapple (e.g., nano, tetra)
Tetra version only, type+enter: wget -O upgrade-2.2.0.bin https://wifipineapple.com/downloads/tetra/2.2.0
Nano version only, type+enter: wget -O upgrade-2.2.0.bin https://wifipineapple.com/downloads/nano/2.2.0
4) Ensure you are still in the 'tmp' directory (root@Pineapple:/tmp#), then type+enter: sysupgrade -n upgrade-2.2.0.bin
The WiFi Pineapple should begin the firmware upgrade process and reboot. The overall upgrade should take about 1 - 2 min to complete.
Setup the WiFi Pineapple using factory default setup procedures on wifipineapple.com.
SEPARATE NOTE: Anyone who is still learning and needs some help setting up your wifi device or interested in some online tutoring in IT/cybersecurity, then feel free to reach out to me on this forum for help! Fyi - Even though I'm a customer of Hak5 products, I am not representing the developer(s) and/or Hak5.
