What @JoshK said above 100%!
Also, I’ve never had problem issues with WiFi connectivity but if you do get your problem resolved please be aware that there is no Alexa skill for the Anova and there are no plans for development of one. But as @JoshK has said, the Anova is extremely easy to run manually. I only use WiFi to check and make sure everything is still running when I’m away from home. And even that is just to give me that “warm fuzzy feeling” that all is well!
