I am having trouble trying to do an upgrade. I get the error: Current version: v2.21 Error, check internet connection. I have tried various resets and power cycles. Is there any way to further troubleshoot the issue? It is in close proximity to the wifi router, about 4 feet away, and shows strong signal strength. I can reach it fine from other devices in the network.
I haven’t heard many people have issues lately, but that is a fairly old v2 firmware (perhaps January 2020 I believe).
Let’s try having you upgrade manually. First, check your available memory, especially if you’ve loaded a bunch of patterns on this device. I forget for that particular firmware how much must be available, but it’s be good to see 100K available or more. To be safe, you could export a few of the largest patterns first and delete them from that controller.
