Model: TL-WPA4220  
Hardware Version: V4
Firmware Version: 4.0.2 Build 20180308 Rel.37064

Has anyone else noticed this?

 

I have the above device plugged in and it has a DHCP assigned IP address 192.168.1.69 which it has obtained from an ASUS RT-87U router.

 

This works well until I examine the logs. It appears that the TP-link device doesn't honour the DHCP lease time of 1 day and continually polls the router every minute.

 

The workaround is to reserve the address assigned (192.168.1.69) and then assign this address as a static address to the WPA4220, and of course all polling stops and the router won't give that address to any other device on the network.

 

Bug?

Hi,

 

Could you please provide a screenshot of the system log which indicates the DHCP request?

 

Thanks in advance, and have a nice day.

@architect1337 I believe this is by design. The WPA4220 sends a DHCPREQUEST every minute to determine whether or not there is an existing DHCP server on the network. If it gets a response then the 4220 will not act as a DHCP server itself. If it doesn't get a response or if you configure it with a static IP address then the 4220 will act as a DHCP server.

Unfortunately this behavior results in a lot of log spam.

 

Regards,

 

Jonathan.
