OpenWrt support for Xiaomi AX3000T

lapis · July 28, 2024, 9:17pm

WED works fine for me on 23.05.4. Speedtest on 500 Mbps speed does under 10% CPU usage. I don't have packet steering enabled.

Have fun testing these, given I don't even own an AX3000T? (Ie. Don't flash these unless you actually have a confirmed working setup where you have uart and mtkboot working and a desire to resolve yet another flash swap by Xiaomi...)

Quilt is thoroughly unfun because I never can remember the arguments.

Link removed! Suitable patch now in OpenWrt master

The difference between the mediatek patch currently in u-boot and what's in mainline...

Pretty sure there are style issues that prevent me from sending this to linux-mtd as well? (I didn't run checkpatch)
W25N04KV_STATUS_ECC_5_8_BITFLIPS probably needs a rename given it's shared with a whole lot of chips and may signal a different amount of bit flips between them. (I didn't take a look at the datasheets for the other chips yet, but at least this one is 4-bit and the 02/04 are 8-bit ECC.)

aaron2421 · July 29, 2024, 4:20pm

how ?
on mine, it goes upto 50 to 60 % on 250MB speedtest.

andi-at-1 · July 29, 2024, 6:51pm

Thank you very much!!
I can confirm the initramfs and sysupgrade works fine, but i cannot test the bootloader cuz the opkg package for rw is already unavailable

So how so i get this?
opkg install kmod-mtd-rw

lapis · July 29, 2024, 8:50pm

I don't know... Did you install AQM? That takes a lot of CPU. Buď WED works for me (and I don't use WED nor Adblock now).
But I have a bit issue with download speed over wifi. I just upgraded to 1 Gvit internet tarif and wifi speed seems to be just around 500 mbit download and 800 mbit upload.
I tried also 160 MHz channel, but that was even slower. Tried disabling WED and other things, but it didn't increase the speed..

namidairo · July 29, 2024, 9:01pm

That was just included for the sake of completeness, uboot in master already had the patch from the MediaTek feeds.

Thanks for confirming that the images do in fact boot though.

My router is bricked and I bought new memory winbond w25n01gvzeig, does anyone have a full dump to restore? Or maybe I can flash only the bootloader and then everything else through it?

unprofessionalx · August 1, 2024, 7:03am

I just installed the latest official snapshot 8/1/24. The kernel and I believe wireless drivers were updated. The wireless seems more stable and seems to be working much better than the previous snapshot 7/29/24. I use the AX3000T in client mode. Previously, the phy rate and signal strength was unstable I would lose pings to my gateway router.

Model	Xiaomi Mi Router AX3000T
Architecture	ARMv8 Processor rev 4
Target Platform	mediatek/filogic
Firmware Version	OpenWrt SNAPSHOT r27055-e6fec638d2 / LuCI Master 24.212.79282~65b8002
Kernel Version	6.6.43

Hi, is there any way to tell what flash is inside without unsealing the case?
WIKI only mention to be careful about winbond flash but no easy way to tell without unscrewing the case.

(OpenWrt support for Xiaomi AX3000T - #790 by andi-at-1)

andi-at-1 · August 2, 2024, 5:02am

Wiki page has the firmware, flash it with the xiaomi repair tool (maybe from an old pc cause of the ransomware warning....) or figure out how tftp works

Mabe your router needs one day of sitting around or many attemps of holding reset while powering on to get it into fastblink - flash mode

Flash the immortalwrt firmware afterwards

thiagohflima · August 2, 2024, 6:04pm

What do you mean by “more stable”?

Here, after upgrading to OpenWRT (from stock), Wi-Fi coverage seems the same, but it isn’t reliable. Sometimes my iPhone shows full signal strength, but it takes a long time to open things.

It’s like it is going back and forth between 2.4GHz and 5GHz.

The stock one was working so far so good.

jdwl1o1 · August 2, 2024, 8:49pm

That is not usual behaviour, there are many, many people using this router with openwrt without issues

I suggest resetting to defaults and configure your device from scratch.

If you think your clients are hopping frequencies set each band to its own ssid

if you can read Chinese and the oem firmware works for you, it is reasonably performant, just with the normal oem caveats that it is old and limited and unlikely to see updates

Underworld · August 2, 2024, 10:20pm

I can confirm your observation, as I am using it with wds to cudy wr3000.
Signal strenght is now stable at 55 dbi and bandwith 2.4 gigabit.
With snapshot from june, it varied from 59- 56 dbi and bandwith 1,9- 2,1 gigabit.
Happy! I updated both cudy and xiaomi - same soc.

s the recovery in U-Boot working at the moment? I accidentally flashed the firmware from AX6000 and I can't flash it via TFTP.
The flashing process does not start.
192.168.1.254
255.255.255.0...
Are the settings of the computer's network interface correct?
The cable in the router to the port next to the WAN.

MasterAP · August 3, 2024, 10:30am

From the openwrt AX3000T page (with further detailed instructions on the page):

AX3000T can be recovered from a soft-brick with TFTP. The flow is:

The router boots and asks for an IP address on the LAN ports via DHCP
The TFTP server assigns an IP address to the router
The router then connects to the TFTP server (where your DHCP server listen, e.g.: 192.168.31.100) and tries to download a file named with the IP address given by the DHCP server converted to hexadecimal.

Hello everyone,

I'm a beginner trying to install openwrt the first time and I have a few questions:

Is it necessary to flash the initramfs-factory.ubi firmware before flashing U-Boot?
I'm running firmware version 0. Do I also need to flash U-Boot to /dev/mtd9? The wiki isn't entirely clear on this point.
If I flash Namidario's patched firmware for the Winbond issue OpenWrt support for Xiaomi AX3000T - #819 by namidairo , can I update it normally once a stable release with the patch included is available?

Thanks in advance

Lexeyko · August 3, 2024, 11:39am

TFTP instructions for the stock layout

These are different bootloaders and this instruction is not suitable.

Jaidee · August 3, 2024, 11:50am

Does anybody know for sure if I do a factory reset does it revert back to the the original Xiaomi configuration or to the recently flashed OpenWRT release?
I have managed to lose any access, Luci and SSH, by trying to change the IP.

Underworld · August 3, 2024, 11:56am

It will boot Openwrt.
