Model: Archer AX72  
Hardware Version: V1
Firmware Version: 1.2.6 Build 20240619 rel.72016(5553)

Whatever I set the IP lease time on my ISP's device, my AX72 receives it correctly, but still renews every ~32 seconds. This has to be a bug, right? Other devices are correctly respecting and renewing only when needed. I

Re:Router in AP mode is renewing IP lease too often, time passed not working?-Solution

As somewhat suggested in another post, even though it had a reserved IP in my main router/gateway, I had to manually set the same static IP in my AX72, and this stopped the constant renewals. DHCP change from Auto to Off didn't help. So, to anyone in the future using it in AP Mode and having constant IP Renews long before the lease time, just set a static IP in the AX72 itself.

Hi,

 

This appears to be a long-standing issue.  https://community.tp-link.com/en/home/forum/topic/573370

 

I've just checked on my Archer AX53, whose firmware was updated very recently, and the issue is still present. (see the log below)

Thank you, it's hard knowing what exactly to search for, I did not find that specific post when looking for a solution, but I did find others with the same problem. It's a shame this is an old issue and still unresolved, even if it probably doesn't affect performance and not at all security I would guess they would fix it after years.
