I just got a Blue Cave to replace an RT-AC68U as main router in a 3x RT-AC68U AiMesh.
Then I'm seeing issue in getting manually assigned IP from DHCP:
1. if the devices are connected to the Blue Cave (main), they get the assigned IP
2. if the devices are connected to the other nodes, they get dynamic IP usually and they change between 2 IP.
In checking the client list in Blue Cave, what I noticed is all the devices connected to the same AiMesh node have a new MAC address, 3 first parts are the same for devices in the same node (they changed if the AiMesh node reconnects to main), the last 3 parts are the same as the original MAC. I have seen modified MAC when using Wifi Extender, didn't know it's also in AiMesh.
For the same device, 2 MAC and 2 IP (1 assigned, 1 dynamic) are showing up in the client list.
Anyway, I suspect Blue Cave uses the modified the MAC of the devices to assign IP and because the MAC do not match what are in the assigned IP table, so new dynamic IP are allocated.
I fallback to use RT-AC68U as main router (2x 68U and Blue Cave as node) and confirmed that this issue does not exist with 68U, each device has 1 IP in the client list.
I couldn't find any information of it in searching Internet (and there is no support email I can send the issue to).
Is it an existing problem? or new problem in new firmware?
