My macbook disconnects from wifi once per day, quite consistently. I'm just used to it now, and reconnect and within a minute or so I am good to go again.
Things like that are why I wired network to all the important places - like my desk. I work from home. I don't want to think about wifi issues. I think I'd have to spend quite a bit to get wifi that was as solid as being on the wire - and that just isn't worth it to me. I never trust wifi to work, but that said I do have an Echo on each floor of my house and they are wifi only. Once in a while I notice they are spinning blue while they reconnect, but I don't know the last time that it didn't work when I tried to use it.
