Powerline Extender and strange DHCP behaviors
Hi!
Model: TL-WPA7517 KIT V2 EU (AV1000/AC1200)
I am new to this forum and I have also read the thread "Powerline Extender Acting as the DHCP server" and this issue is maybe connected to that thread.
I am a computer nerd running my own DNS and DHCP servers on my home network and been investigating some odd DHCP-things with this Powerline Extender.
1. If I tick the box [Advanced -> Device Settings > LAN Settings > Obtain an IP address automatically (Recommended)] the following happen:
About every 60 seconds it sends a DHCPREQUEST-package even if I have set the lease time to 48 hours.
192.168.###.YYY = DHCP-server IP-address
192.168.###.XXX = WPA7517 IP-address as assigned by the LAN DHCP-server as I have configured it.
Example from the log:
2 INFO 1days, 15:43:03, DHCPC: Send REQUEST to server 192.168.###.YYY
3 INFO 1days, 15:43:03, DHCPC: Recv ACK from server 192.168.###.YYY with ip 192.168.###.XXX lease time 130
Where does the lease time 130 come from? Not from my DHCP-server. Checking the DHCPACK-packages the T1 and T2 are 2 days = 48 hours.
2. If I tick the box [Advanced -> Device Settings > LAN Settings > Use the following IP address] the following happen:
About every 20 seconds it sends a DHCPDISCOVER-package, but that is not in the log. Only the DHCPOFFER-package from the DHCP-server is logged.
Example from the log:
330 INFO 1days, 18:32:48, DHCPC: Recv OFFER from server 192.168.###.YYY with ip 192.168.###.XXX
As the other thread is trying to convey about turning ON and OFF some form of DHCP server, I think there is something strange about the whole DHCP approach here and probably has to be addressed.
I have alot of network equipment on the network, even a TP-LINK RE450, and none of them behave in this strange and odd way concering DHCP.
Nevertheless, it's a good product and it's working just fine! Love it!
Regards!
