Model: TL-WA1201  
Hardware Version: V2
Firmware Version: 1.0.2 Build 20220103 rel.59353(4555)

Started: Since I bought the equipment

Ended: Still happening

Description: When using the AP with DHCP on and Address Reservation on the router (TL-R605) it just doesn't stop asking for an IP every 30 seconds or so, even though the lease has not ended yet.

Some router logs:

1 2022-09-05 14:20:01 DHCP Server NOTICE DHCP Server allocated IP address REMOVED for the client[MAC: REMOVED].
2 2022-09-05 14:19:29 DHCP Server NOTICE DHCP Server allocated IP address REMOVED for the client[MAC: REMOVED].
3 2022-09-05 14:18:57 DHCP Server NOTICE DHCP Server allocated IP address REMOVED for the client[MAC: REMOVED].
4 2022-09-05 14:18:24 DHCP Server NOTICE DHCP Server allocated IP address REMOVED for the client[MAC: REMOVED].
5 2022-09-05 14:17:52 DHCP Server NOTICE DHCP Server allocated IP address REMOVED for the client[MAC: REMOVED].
6 2022-09-05 14:17:20 DHCP Server NOTICE DHCP Server allocated IP address REMOVED for the client[MAC: REMOVED].
7 2022-09-05 14:16:48 DHCP Server NOTICE DHCP Server allocated IP address REMOVED for the client[MAC: REMOVED].

Anyone from TP-Link? I don't see any setting for this or something indicating misconfiguration on my side. If it's a firmware issue can this be fixed in next firmware update please?

Hello   @evan022 

TL-WA1201 the AP itself is also a network client and it will get an IP address from router, from my point of view, it's the common behavior that AP requests an IP around 30 secs.

May I know did you set Smart DHCP OFF and use static IP for the AP,  or do you use Smart DHCP (Default ON) status? You could try the other configuration and see if that makes any difference, but I think that would be the same no matter Smart DHCP is ON/OFF.

Hi @Solla-topee and thanks for your reply!

 

When I use Static IP the AP does not request an IP (based on router logs) because there is no need to since it is statically configured in the AP.

 

When I use Smart IP(DHCP) the logs show that it requests and obtains an IP every 30 seconds or so.

 

My point is, since it got assigned an IP the first time it requested it and the lease is set at 1440 minutes why keep asking for one every 30 seconds thus creating unnecessary traffic but most importantly for me, cluttering up the logs.

 

I am not a network engineer so if this is normal behavior or if what I'm saying doesn't make sense please correct me.

  @evan022 

Thank you for sharing more case details, it's good to know that behavior stops when AP is on static IP. 

As checked with my college, this is how Smart DHCP works on the AP, when Smart DHCP is set ON, AP will continuously request an IP address for the purpose of checking if another DHCP Server in the network, it will turn off its own DHCP server when there is router's DHCP server is detected. 

 

I found there is similar behavior on the Wi-Fi router when the router works in AP mode, here is the thread.

Hope this answer your question.

Tbh it would be great if it followed the lease time set by the DHCP on the network (I have the APs DHCP server off) so as not to flood the network with useless requests or at least have an option to change the interval to whatever we want because using Static IP to solve that seems like workaround to me too, as mentioned in the other thread too.

 

Anyway, thanks for letting me know!
