Add support for Xiaomi AX1800 Wifi 6 router

I'm not sure, I have no experience with ath11k and very little experience with wifi drivers in general. That said, if a driver needs more than 256MB of RAM that sounds like a driver problem to me (GPU drivers possibly being the exception).

How do I will change my Redmi ax5 router region. My router current firmware version is 1.0.44 I badly need to change my router current region. Help please.

Hello everyone and thank you for all your support with this stuff. I gained SSH access with 3.0.34 global firmware an I would want to know two things:

  1. How could I enable the highest numer of WiFi channels in 5 GHz? I tried CN country code and wifi code and another combinations like EU but the channels between 100 and 144 are missed.
  2. How could I reach the highest persistent (it stays after router's reboot) WiFi TX power in 2,4 and 5 GHz? I tried some combinations/mixes but the most I got was 23 dB in 2,4 GHz and 20 dB in 5GHz and as I read before the maximum is 28 dB for 2,4 GHz and 26 dB for 5 Ghz...
    Thank you in advance!

"Xiaomi hasn't released the global firmware for AX1800 yet. And there is a confusion because Xiaomi rebranded the Redmi AX5 and released it as Global AX1800 router. So we aren't sure which is which now."

Just a quick one. I'm on 3.0.34 and did the steps of Xiaomi ax3600 ssh guide with resulting code:0 -s. Still I didn't get ssh access this time.
Is there anything I've missed? Thank you...

Hello @hurjup, I was able to gain SSH access in AX5/AX1800/RA67 with 3.0.34 global stock Xoaimi's firmware using another Openwrt router and the following guide:

Do you have another router with Openwrt installed? This way is the easiest one I found to achieve that goal...

Hi, Can you take a backup of the flash partitions and post somewhere? I'd like to run the international version of the firmware but there is no firmware download available yet for 3.0.34 version :confused:

That is not the Mi Router AX1800. It's a custom-made model CR6608 for China Mobile (a Chinese ISP).

That model is supported by OpenWrt: https://github.com/openwrt/openwrt/pull/4118

(It is MediaTek btw... AX1800 is Qualcomm lol)

How could I do that backup?

updated the wiki entry slightly (added some info concerning the confusion between rm1800/ra67. added the oem bootlog from my EU region ra67 ax1800) and fixed the wrong information pointed out by @medeyusa.

If someone is not happy with this let me know, first time editing the wiki :wink:

Could someone back up his int/global firmware?
I can't find it anywhere… Ty!

I have that firmware. How could I backup that?

Download busybox for arm(this might work https://www.busybox.net/downloads/binaries/1.21.1/busybox-armv7l) and put it somewhere on the router, then on your computer run

nc -l 1234 > mtd1

then on the router

./busybox dd if=/dev/mtd1 | ./busybox nc <your computer ip> 1234

Do this for each mtd device in /dev/mtd*, some might fail because they're in use but as far as I can remember, the important ones are dumpable. You can get the real partition name of each device by running

cat /proc/mtd

Please help me! Does anyone have full backup of redmi ax5/ax1800 bootloader or mtd dump, I need to flash back stock firmware due to my ax5 bricked :(((

Does anyone know if there will ever be a OpenWRT support for the xiaomi ax1800 router?
I have 3 but will change them out for something better if not :slight_smile:

Not possible since no one is working on it right now

Guys, you may upvote as much as you want, but the 256MB of RAM really isn't worth somebody's time to get this running.
Even QCA has had a hell of a time getting ath11k to work at all with that much RAM
