Add OpenWrt support for Xiaomi "Redmi AX6000"

who_what8 · September 11, 2023, 6:39pm

Just curious: are you running irqbalance?

Nope (post be me at least 10 characters)

Anyone using 160Mhz frequency with mesh network? I'm able to create an access point with 160Mhz and have clients connect to it, but if I setup a mesh network with it then it does not work. Changing back to 80Mhz works perfectly. I do have 3 AX6000 forming a mesh network at home and trying to make it 160Mhz in an attempt to make the speed drop less significantly as the routers will have the double amount of bandwidth available to it.

For mesh to work I do have wpad-mesh-openssl (2023-06-22-599d00be-2) and mesh11sd (2.0.0-1) installed. I'm running a fresh install using OpenWrt SNAPSHOT (r23900-7f54d9ba1a), installed yesterday.

Logs when using 160Mhz. Tried to search for this error message but could not find much useful recent information.

So, how it's been going after disabling offload?

who_what8 · September 13, 2023, 3:06pm

So far so good, 2 days uptime as of now.

soxrok2212 · September 13, 2023, 5:28pm

Broken here too. In most places, you have to use a DFS channel to get 160MHz. Unsure if the radar scanning function is broken in mesh mode, but it doesn’t work for me either.

anon_openwrt · September 13, 2023, 5:52pm

I was having issues with wpa2/wpa3 mixed mode WDS, since switching to wpa3 WDS works fine, I'm using dfs channel 100 160mhz ax, not sure if applicable to 802.11s but you never know.

efpiva · September 14, 2023, 9:13pm

Tried different security settings and none works with mesh, seems radar function is broken for mesh indeed.

Hello!
My router ax6000 bricked.. so I've tried tftp64.

This is tftpd64 setting,

And this is TFTP log,

but router cannot load firmware file..

I installed Wireshark to see packet, but it says there's no file.

I want to unbrick it and re-install openwrt.
Please help me Thanks!!

Are you sure you have C0A81F02.img file in the folder?

910051 · September 17, 2023, 3:24am

of course, I downloaded the original rb06 firmware ver 1.0.48, and changed name to 'C0A81F02.img'.

KingCZE · September 17, 2023, 4:45am

By any chance, do you have access to Linux? I wrote up the guide on https://openwrt.org/toh/xiaomi/redmi_ax6000#tftp_instructions_for_the_stock_layout, but I have never used Windows for this. On linux, sometimes, there are issues with the file name and the user permissions, but I guess this should not be an issue on Windows.

I don't see a mistake in your settings. Tftp is clearly connected, if you have the file in the correct folder with the correct name,... but it apparently cannot see the file. I put the following note to the guide: "The router will be looking for a specific file name on the tftp server – if the requested file in the terminal does not match the one you have in the tmp folder, rename it accordingly and proceed again", because with some newer versions, it changes the requested file name, but apparently, this is not an issue in your case.

Delete the folder and try following commands in cmd and try to run tftp again:

bash

# To create a directory in Windows CMD, you can use the md command. To create D:\tftp, you can use the following command:

md D:\tftp

# To download a file from a URL in Windows CMD, you can use the bitsadmin command. To download the file to D:\tftp, you can use the following command:

bitsadmin /transfer mydownload https://cdn.cnbj1.fds.api.mi-img.com/xiaoqiang/rom/rb06/miwifi_rb06_firmware_847e9_1.0.48.bin D:\tftp\C0A81F02.img

# To change the permissions of a directory in Windows CMD, you can use the icacls command. To grant full control to everyone for D:\tftp, you can use the following command:

icacls D:\tftp /grant Everyone:F /T

Have you tried using the Xiaomi Recovery Tool as described here ?

Not sure if it works for Redmi AX6000 though. Only suggesting this as from your description it seems you are trying to revert to stock firmware. This obviously may only work if you haven't yet converted to OpenWrt U-Boot layout.

iisquazar · September 17, 2023, 7:44am

I've used this tool to flash OpenWRT after I bricked my AX6000. Works like a charm.

Edit:fluctuating internet speed were due to my Redmi AX6S that gives fluctuations in wifi speed in latest snapshots. Reverted to latest stable solved the problem.

910051 · September 17, 2023, 9:25am

Thanks!! I did this and it works!

KingCZE · September 17, 2023, 8:01pm

I'm happy it worked.

midi · September 22, 2023, 7:14pm

Hi,

I found a bunch of AX6000 on sale and I was thinking of picking them up. My main usage of them would be a wired mesh (ethernet backhaul). I see that there is openwrt support for it, which means for me that it will live for a long while. My question for those who have them are:

how is the routing performance? (I would prefer if it can go up to 1Gbps consistently, be it on stock firmware or openwrt)
how is the wireless performance and range?
do you guys recommend getting these or look elsewhere?

I know there are more expensive options, but im doing this for home usage, but also need it to be performant enough not to struggle like my aging Archer C7.

Thanks!

ercolino · September 22, 2023, 9:06pm

is that in europe? i think i need a new device to play, and this is the right one.

midi · September 22, 2023, 9:17pm

on aliexpress. they come with the chinese firmware and probably are being phased out, hence the lower prices. But for me I'm more interested in the performances of these devices first before getting them.

kastellsc · September 22, 2023, 10:04pm

As I am using as a dumb AP I can't speak about too much aspects of it, but I can say:
It's Rock solid
The performance of wifi is awesome: long range and fast speed
Don't have a single problem. For my usage it's perfect
