MANY THANKS. I am not sure what is normal here. Seems like it should stay connected all the time but realize it probably only updates the data depending the settings and is not "live". I think I set mine 2m/12hrs. So i bet it only needs to connect every 2m. Totally agree it does NOT affect the performance tho. Controller is rock solid. I am not a guy to look at my phone every minute but do expect that when I do look I will get accurate info and not having that yet. My issue is that it does not connect when outside and it really isn't that far away from router. It shows connected but temp 0 Celcius. Wifi light on controller long flashes. I tried an extender and did not help. Hoping reinstall fixes.
Other simple things to check.
Since you messed with your router and renamed your two bands (2.4 and 5.0) are you sure the Auber is setup to talk go the correct band?
Also, you may need an extender very close. I have my extender on the inside wall outlet that is literally on the opposite side of the wall from my smoker. Had my wifi PID setup to connect to it and all was well... until the wifi portion of my PID died (my PID is a Heatermeter not an Auber). I just live without wifi but it taught me a lot while it was working. I no longer need the feature and just rock on without it :)
These things are easy to check without buying equipment and so on. I always tell people I work with that it cost almost nothing to double or triple check but costs quite a bit to go another route and be wrong only to find something that could have been fixed with an extra check :D
