Orbi failed and needs to reset to factory settings every two weeks

I bought my Orbi + 1 satelite around Feb 2017.  My router was from my ISP the Hitron CODA 4582 and the Orbi is in AP mode.  Works fine after setup for 2 weeks.  Every two weeks, there's no internet connect from all the Wireless devices (all my wire device is good) and whatever I do can't seem to resolve it except reset to factory setting and do the setup again.  Its a nightmare since been doing this so many times to the point I am telling myself not to buy another netgear product (this is my first netgear product).  The frimware is updated. and one more annynonance is latest Orbi app update makes the setup DOESN'T recongnize the code it scan (works fine until recent update).  Any suggest how to keep this this up for like foreever like very other wireless network product I use in the past?

Thanks.
