I'm using my DECO M5 for several years. In 2019, I had a big trouble, such as unstable connectivity, no internet after updating firmware into 1.2.5. At that time, I received engineering firmware form

Previously i was running on 1.2.4 - Not a single issue in > 6 months! (so very stable connections, no disconnecting nodes, no disconnecting clients => rock solid) Immediately after the update to 1.2.8
