I have a Xiaomi mi router, and I have made this simple configuration:

internet --- main router (with internet)------lan cable----xiaomi router

I want to use the wifi from the xiaomi in another room. So I have disable DHCP on the xiaomi, setted up the wireless, and restarted it. To make this changes I connected to the router default address: 192.168.31.1. After having restarted everything, I am able to access to internet from the deviced connected to the Xiaomi mi router wifi, but can't access the router anymore to the address 192.168.31.1. If I go on my macbook network panel to see which router I am connected to, it indicates my main router with the IP (192.168.178.1).

But I am connected to the xiaomi router. It is like my xiaomi in "invisible", but I am not an expert of network, so I can't understand why, and how I can do a proper configuration to achieve the same result but mantaining the access to my xiaomi router.

This is exactly what you need, take a look. You need to make sure the plug is not the "Internet" port instead its the 2 other port. https://www.nextofwindows.com/how-to-configure-mi-wi-fi-as-second-router-to-extend-existing-network-same-ssid-roaming

Kinda amusingly, the 'easiest' way to sort this out is by network scanning your network and identifying which one of these is your AP.

Zenmap is a pretty nice front end for nmap.

These are the settings I use. You'll want to change the target to "192.168.31.1-255", and hit scan. Then go have a cup of coffee. This takes a little while. It seems to do nothing at this time so be patient.

Essentially this gives you a list of hosts, and what they are running. Some interpretation is required depending on your device.

Once its done, it looks like this

You can click through each host, and interpret the output

The output looks something like this ideally - it tells you what ports are open, which is useless here, and then this information. The service info line is typically what you want in this case.

MAC Address: AC:22:00:00:00:00 (Asustek Computer)



Device type: general purpose



Running: Linux 2.6.X



OS CPE: cpe:/o:linux:linux_kernel:2.6



OS details: Linux 2.6.8 - 2.6.27



Network Distance: 1 hop



Service Info: Host: RT-N56U; Device: WAP

This tells me My MAC address (and I can google the first 4 letters there to doublecheck who made it), what I run, and what it actually is - a RT-N56U access point.

In the case of my other AP, there's a bunch of junk data.

MAC Address: C4:A8:1D:84:F3:59 (Unknown)



No exact OS matches for host (If you know what OS is running on it, see http://nmap.org/submit/ ).....



Network Distance: 1 hop



Service Info: OS: Linux; CPE: cpe:/h:dlink:dir-865l:1.07, cpe:/o:linux:linux_kernel

Zenmap can't quite identify what it is, but gives you enough information to ID what it is - look at the service info line. It tells me it runs linux, its a CPE (consumer premises equipment) and its a dlink, dir-865l running firmware 1.07

It’s years old, but it deserves an answer!

First of all: There is absolutely no need to reset anything.

Your Xiaomi router is still reachable at 192.168.31.1. However, to communicate with it, you need to be in the same subnet. Currently, with DHCP from your main router, you’re in the 192.168.178.0/24 network while you want to be in the 192.168.31.0/24 network.

To access your Xiaomi router, manually change your PCs IP address to 192.168.31.2. You will not be able to access the Internet like this, though.

To be able to access your Xiaomi router during normal operation, you need to change its IP address. You could use 192.168.178.2, for example. Just make sure there is no IP address conflict. Preferably, the address would also be outside the DHCP range of your main router.
