Tags: #Address Reservation
Model: Archer C80  
Hardware Version:
Firmware Version:

My router's ip address is 192.168.2.1. My desktop computer has WiFi turned off with its wired (only one 1 network adapter connected directly to the router) MAC Address reserved as 192.168.2.11 (in the router's admin DHCP Address Reservation List) to the the wired MAC Address. However, it never allocates t92.168.2.11 but allocates a new Permanent 192.168.2.10x (i.e. from the Pool of ip addresses, which aren't reserved) when I disconnect wired & reconnect it. Why is this happening and how can I make the router 'behave'?

Try to delete that via Advanced=>Security=>IP & MAC Binding=>ARP List:

 

 

or if that doesn't work just reboot teh router.

Using DHCP address reservation makes sense when the reserved IP address is in the router DHCP address pool.

Outside the router DHCP pool you could set your static IP addresses.

So try to reserve an IP address in the router DHCP pool and check if that works as expected.

I changed DHCP Pool to include the rtequired static (i.e. reserved address) of 192.168.2.11, disconnected wired & reconnected wired. On the attached screenshot, it says that 192.168.2.11 has 2 permanent ip addresses. How do delete the 192.168.2.109 one?

Thanks, terziyski. Useful to know about about ARP List. I've now done that for my DHCP Reserved Addresses. I've found out the cause of the problem. The wired MAC Address of my desktop was set to Random rather than Permanent. All now Ok: confirmed by actual hardware address displayed by "ethtool -P eno1" displaying in ARP List, DHCP Reserved Addresses and DHCP Client List.
