I have run into what I believe is a firmware bug in the BE500 V1.0 firmware version 1.2.1 Build 20250813 rel.27119(5553).  It appears that no matter what the DCHP lease time is set to on my main router (BE800 on 1.3.2 Build 20251015 rel.10659(5553) that the BE550 requests a new DCHP address every 34 seconds around the clock.  I have attempted to set a static IP, change the lease time (currently set to 2880 hours) and switched from wired to wireless backhaul without any change to the DCHP request behavior.  I believe this to be a firmware bug.  Snippet of logs from the BE550 below.
