Hardware Version: V1
Firmware Version: Firmware 1.2.1 Build 20220512 Rel.76748

Hello TP-Link Engineers

 

 

The DHCP Address reservation is not working correctly. I saw in the logs that it rejected the MAC address of the device that is reserved with a specific IP Address.

It was given the wrong IP Address with permanent lease time.

 

Please fix this issue.

 

Thank a lot.

Dear @EnzoConqueror,

 

Sorry for the late reply. Could you please try the ER605(UN)_v1_1.2.2_Build 20230118 (Beta) provided in this solution post and confirm whether the issue can be resolved?

  @EnzoConqueror I had a similar issue where my ER-7206 router would start rejecting DHCP requests from clients. Turned out to be a rogue DHCP server on the network. Once I shut that down, the problem went away.
