Archer AX55 requests IP-Address every minute or more (DHCP-Request)

2023-09-16 15:51:33

Tags: #Firmware Update

Model: Archer AX55

Hardware Version: V1

Firmware Version: 1.2.3 Build 20230603 rel. 46473(4555)

My new Archer AX55 sends every minute or more a DHCP-Request to my DHCP-Server. This causes unnecessary network traffic and fills logfiles on the server.

The router mode is "AP" with Dynamic-IP. Static-IP is not an option for me.

DHCP-Server is "ISC DHCP server" on Debian. Default-lease-time is two hours (7200 sec), but Archer AX55 ignores it.

Interestingly different DHCP-Server versions behave different:

isc-dhcp-server 2:4.2.4-7.1 makes short DHCPREQEST und DHCPACK sequences without interaction with the DNS-Server.

isc-dhcp-server 4.3.1-6+deb8u3 nearly every time (but not always!) makes a complete DNS-Server delete and adding operation. Sometimes only a short DHCPREQEST and DHCPACK sequence is made.

Unfortunatedly it is not possible to attach sample logfiles here.

I have seen similar posts about this problem with very frequent dhcp-reqests. Is there a chance that it will be fixed with an firmware update?

@Markus_

A similar issue has been reported in this thread.

You wrote that a static IP is not an option for you - just for the test you could set it as static IP.

Also if there's an option for your AX55 DHCP Server setting as "Auto" set it to "Off" an check if there's any difference.

If this was helpful click once on the arrow pointing upward. If this solves your issue, click once the star to mark it as a "Recommended Solution".

@terziyski

The device is in "real use mode" now, so I cannot make such tests. Probably the problem goes away with "Static IP", since several reports in this forum state that.

DHCP-Server of the device is set "OFF" of course. Never have more than one DHCP-Server in your network (-segment)!

If someone (from TP-Link) is interested in my DHCP-Server logfiles, please let me know.

Can it be, those exceedingly DHCP-requests are not a bug but a feature? In order to keep up with possible IP-Address changes from the ISP?

Does anyone of the TP-Link engineers read this post?
