I recently attempted an update to ResinOS. I had been running my Raspberry Pi 3 B on ResinOS 2.12.7 and using Resin.io to manage it. On ResinOS 2.12.7, the RPi’s wifi was working well, and Resin Wifi Connect also worked well when I tested it on the same ResinOS version.
Due to some unrelated issues, I chose to flash a fresh ResinOS image for this RPi, and used the ResinOS version 2.13.6, enabling Wifi access with the correct network and password. On flashing that ResinOS version to my SD card, inserting as usual into my RPi, and restarting the RPi, the RPi did not appear on my Resin.io dashboard.
When I used a wired internet connection, the RPi did connect successfully and showed up on the ResinOS dashboard. I let it download and install my containers, and then attempted to switch back to Wifi. It did not connect.
Since I have Resin Wifi Connect installed and running in one of my containers, I used it to reassign the network and password. The RPi still did not successfully connect. I then attempted using Resin Wifi Connect to connect to a different network. That also did not work.
I flashed a ResinOS 2.12.7 image to my SD card with the appropriate Wifi network and password, and the RPi immediately connected via Wifi and showed up on the Resin Dashboard. That confirms that this is not a hardware issue. (The tunneling socket hang-up errors did resume, however).
I next attempted to update to ResinOS 2.13.6 from 2.12.7 from the Actions tab of the Device, as outlined in https://docs.resin.io/reference/resinOS/updates/self-service/. I received the message that it had successfully updated, closed the ‘update’ window, and saw that the device was offline.
Something about the new ResinOS update (2.13.6) seems to be interfering with the RPi’s Wifi access. Any ideas what is causing this? (Temporarily, I can just stick with 2.12.7, but I would like to be able to update in the future). Is there something I can do on my end to fix? Or, ResinOS team, can you fix it on your end?
(Also, are there ChangeLogs available for the 2.12.7 -> 2.13.6 update?)
