Router + repeater IP&MAC problem

[0v3rl0rd]

Hi
I have a Mi WiFi Router 3 set up as an WiFi repeater. I did the setup via URL (192.168.31.1).

I finished the setup, and on the final step I got a message that the MiWiFi repeater's IP address is now: (A1) 192.168.5.25.
If I go to that address I can access the Mi Router normally. In MiWiFi root settings the MAC address is the same as written on the product sticker itself: (B1) x0:xx:xx:xx:xx:xD

When I go to the MAIN router's settings I get the information that the MiWiFi's IP address is (A2) 192.168.5.19.
If I go to that address I cannot access anything.
Also, the MAC of MiWiFi (shown in the main router's rott) is: (B2) x2:xx:xx:xx:xx:xE

If I go to tracert I get the following:
(A1) 192.168.5.25 >> I get the SSID of the wifi: "WiFi_RPT [192.168.5.25]"
(A2) 192.168.5.19 >> I get the original name of the Mi router: "MiWiFi-R3 [192.168.5.19]"


It's weird that the MiWiFi shows its MAC address correctly but that same device is displayed diffferently in the main routers settings.

So, the only time that I get to know the correct (accessible) IP address of my MiWiFi is on the last step when I'm finishing MiWiFi's setup.
Afterwards, as I said, if I go to the main routers settings I get a wrong MAC with a wrong IP address from which I cannot access my MiWiFI repeater.

Any help?

Depending on the implementation of the software, this is not wrong. You have 2 interfaces ... one in and one out. Each has it's own IP address and MAC address. It is a bit unusual. Other wifi extenders I have used are invisible on a traceroute. I do wonder if you did the setup as a router or as a "wireless amplifier" as the setup guide calls it.

In the setup I chose "Wireless repeater".
I get it that it may have 2 interfaces (1 in, 1 out), but shouldn't the router itself have only ONE FIXED MAC ADDRESS?

But the most anoying thing is: why 2 different IP addresses - one accessible (with original MAC) and NOT SHOWN in main routers connected devices, and the second which is shown in the main router's connected devices (with that modified MAC) and which is not connectable... :/

Weird.

If you have 2 distinct interfaces, then each gets it's own MAC address.

I think the issue is that most extenders (repeaters) work like a network switch. They just forward data. That is why they are invisible to tracert (technically, it has to do with OSI levels). This is a router that has been cudgeled into an extender, so it maintains the router infrastructure, but does not do any of the NAT or DHCP or IPsec or etc etc etc.
