XP8 gateway buggy in Bridge mode drops Ethernet WAN

My XB8 in bridge mode intermittently drops Ethernet WAN. The router sees random WAN failures and DHCP outages.  Using Orbi 771 router which freezes (purple light) and must be rebooted when this occurs.  I could switch the Orbi to AP mode but this configuration isnt optimal.  Reading that the XB8 is "buggy" and known for this any input from those with greater knowledge than I?
