My B20X displayed a solid red led after about a week on 8.2.0. RC2. I shipped it back under warranty for repair or replacement.
I acquired an Archer AX-1800 as a temporary replacement. This WiFi router is 3X faster as an OpenVPN client than the B20X. The latency on the LAN also seems to be less. The WiFi coverage in my home is so good I do not need the Enterprise AP with this product. Not sure I will go back to the B20X when it comes back from repair because I do not need the dual WAN feature on it.
