Model: Archer BE550  
Hardware Version: V1
Firmware Version: 1.2.1 Build 20250813 rel.27119(5553)

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.

Re:BE550 34 second DHCP request loop

  @Jstewart0131 The BE550 DHCP Query Frequency seems to be set to Continuous.  I suggest you hard reset it and try reconfiguring it.

Reset both the BE800 and BE550 this morning and still getting the same behavior from the BE550. Seems like a firmware bug at this point.

Hello  @JohnSkawinsky & @Jstewart0131 ,

 

Currently, satellite nodes are indeed requesting DHCP renews approximately every 30 seconds. Could I know what specific impact this will have on your use of EasyMesh networking?

 

We highly value user feedback and user experience, and our technical department has engaged in fruitful discussions on this topic. We also hope to improve this mechanism as much as possible in the future.

 

Best Regards.

I changed router to AP mode only and situation is stable now, with no redundant logs.

  @Joseph-TP I was just reading the log kindly provided, and it seems the lease provided is for 172800 seconds?  I just checked and that is 2 days.  Why would the EasyMesh node consider 30 seconds as 1/2 the lease period when it should be 86400 seconds/one day?  Seems like a lot of unnecessary query frequency when they could be processing other things....
