You should start your own support thread to open a ticket, if you haven’t already opened one via email.
Maybe something local is causing issues. Maybe your machine has a problem.
A lot of the answers that you see here from forum members are going to be WiFi related comments, because those are the things within a users control that they can check/work on.
The machine is logging a lot of data, and often times Support can pin down the cause from those logs. I’m not saying it’s your internet - but it wouldn’t be the first time that someone claimed to have perfect, amazing internet and their internet actually turned out to be the issue.
I can say that in the time that I’ve had my unit, the only WiFi/calibration/etc issues I have had (very seldom) have not been from the GF side - they’ve been from Nighthawk router.
I’m sure it’s frustrating… and that stinks. If the unit needs some kind of fix, they will get it fixed. I’m not alone in my experience above (as far as reliability)… I know that doesn’t make you feel better about your current situation, and it’s not rubbing it in your face - it’s saying that yes, the machine can be very reliable.
Sorry to make you puke.
