Xiaomi Wifi Router 3G - 18.06.X / feedback and help

Due to the closure of the developer's topic for the Xiaomi Wifi Router 3G (Xiaomi WiFi Router 3G) I'm creating this new one so we can talk about the recent release of OpenWRT 18.06 and it's future service releases and how it's perfoming on the Xiaomi 3G.

how to could I check that I'm running the last firmware revision?
Luci tells me:

I upgraded successfully to 18.06.1, there a few config parameters which went lost (e.g. extra login, soft packages). But I could quiet easily set them again.

I want to install OpenWRT on my device.
It's running padavan fw. Can I flash openwrt from padavan without going back to stock?

Need help, I hope the 3G Router is not bricked.

I just installed OpenWRT on my router.
Now I can get my full internet speed.


If someone would have at least a link for me that could help me get my Mi 3G Router back to life?

I've installed 3rd Bootloader Breed, and OpenWrt 18.06.1.
But I cann't change the LAN IP. LuCi keeps telling me cann't apply the changes.
Anybody can help?

Everything goes sweet, till I changed the LAN IP from to
now I lost every possible connection to the OpenWrt system.
I tried both IP, using webUI and SSH, but none of them works.


that happened to me on 18.06 also... seems like it was not fixed...

I bricked mine and i unbricked it by using serial connection.
These links helped me to do this:



For this you will need a usb-serial-connector and a pin ledge.
But it's worth it - you learn a lot again.

Official documentation USB 3.0 and WiFi problems:

or disable the USB3 driver to force fallback to USB2.0. Many current LEDE devices aren't even noticably faster on USB3.0 data transfers compared to 2.0.

Could someone point me how to disable USB3 driver? It seems that USB 3.0 is compiled into the kernel. Removing of kmod-usb3 package does not help. The same with rmmod xhci-hcd.

So, I see a ton of complaints that 2.4 WiFi does not work in pair with OpenWrt if you have connected USB device. Of course, I have external USB card-reader + microSD card.

The same configuration works excellent with stock firmware. But! There is the one significant NOTE! Xiaomi DISABLES USB 3.0 by default in their stock firmware. They even write in GUI that enabling USB 3.0 will gift you a ton of problems for 2.4Gz.

Why we can't resolve this issue finally and make people happy with OpenWrt? Why should all people move back to stock?

Thanks in advance!

That's interesting, and I would test building a firmware without USB3. Maybe you can put the message in the thread about wifi issues on the 3G? Xiaomi Wifi Router 3G - 18.06.x / Wifi issues 2.4GHz + 5GHz

It makes it easier to keep track of the topics.

I just flashed 18.06.1.
After initiated the password, I exited LuCi without any configuration change, and power off (I mean plug off the power supply) and on, to see what happens.
Bingo, LuCi is dead.
The good news is SSH still alive.
It looks like OpenWrt is not available for Xiaomi router 3g, not yet.

There have been several reports about broken config files when pulling the plug instead of shutting it down properly. Setting the password is a configuration change.

But actually, there is no ¨power off¨ option in LuCi, is it? Only reboot.
What if I need to move the machine to someplace else T_T
Power off in SSH?

Sorry, I usually do it using "poweroff" in the shell so I hadn't noticed. You should probably do a reboot after the first boot and possibly after configuration changes, then.

Great, I will try, thanks.
