Hi,
I recently got the WiFi IOT expansion card for my MangOH Red with a WP76. I was following the installation procedure outlined here WiFi expansion card tutorial when in the middle of the ssh session the device disconnected. I haven’t been able to connect to device at 192.168.2.2 since then. Looking at the console log, I see this error in particular that is recurring every few seconds
