OpenWrt support for Xiaomi AX3000T

lapis · 2024-10-20T21:07:10.199Z

I had prpblem with my AX3000T (RD03 with ESMT NAND, that came with 1.0.47 FW) today. Out of nowhere (maybe after scheduled reboot that I set weekly), it stopped working and orange LED was blinking slowly (blinked every few seconds). Wifi was not active and when connected to LAN, I didn't get IP and Windows also slowed that cable got disconnected every few seconds.
Unplugging/replugging power nor pressing or holding reset button didn't help.
I had to use MiWifiRepairTool to flash 1.0.47 and switch to OpenWRT again, which fixed it.
I was on official 23.05.5 OpenWRT with stock bootloader.
Any ideas what could happen?

ideas - there are.
Soft brick after 7 reboots.

The openWrt team needs to apply a patch that fixes this problem.
Read the topic and register a command in the auto boot that fixes this problem.
Install a custom bootloader and the corresponding openWrt firmware for it.

As I see PR has been merged to the 23.05 branch

[23.05] generic: 5.15: add Winbond W25N01KV support

openwrt:openwrt-23.05 ← robimarko:winbond-w25n01kv

It seems that some Xiaomi AX3000T boards changed to using Winbond W25N01KV SPI-N…AND which is not supported in OpenWrt 23.05 but only in main. So, backport the support for Winbond W25N01KV from Linux 6.12 to 23.05 as well.

Please install ‘ubootmod-type’ firmware only with the bootloader from the snapshot or my build if your spi-nand by Winbond (Winbond chip support in the OpenWrt bootloader is available there).

This commit should be merged into the 23.05 branch to support the Winbond chip for ubootmod-type firmware (OpenWrt bootloader).

what does the merge do? does that mean we can use official release instead of snapshots for the ax3000t with winbond nands?

lapis · 2024-10-21T08:32:25.110Z

Yes, I noticed some messages about resetting the counter before, but I had feeling that it is required just on newer routers with newer Xiaomi bootloader, so didn't pay much attention to it.
I added fw_setenv flag_try_sys1_failed 0 to /etc/rc.local as precaution, hopefully it will prevent this from happening again...

jojosupir:

how about AN8855 variant?

Continue to look for alternative build, an8855 not supported in the official repository, until drivers for this switch will not be present in the Linux kernel.

Driver for the Winbond chip have been added to the 23.05 branch for firmware support, but no changes have been made to the OpenWrt booloader (OpenWrt layout - ubootmod) in the 23.05.

I'm testing AX3000T on a restaurant for future network upgrade, but a've noticed poor speeds on 5GHz ramdomly, solved with radio restart, but when it occours, the network goes down due to low speed/high latency.

The AP is running on 80MHz/AX mode.
Openwrt 23.05.5.

Try turning hardware flow offloading off (just leave software flow offloading on). Crappy 5 GHz performance seems to occur on some phones for me, when hardware flow offloading is enabled, but not on a laptop.

Lexeyko · 2024-10-21T11:44:17.769Z

Replace the wpad-basic-mbedtls package in the firmware with wpad-wolfssl.

tried to install ubootmod, but have issue with wireless settings and devices. creating '/etc/config/wireless' has no effect, and dmesg has such errors

maybe someone stumbled upon same issue and know how to solve it ?

Lexeyko · 2024-10-21T16:56:40.937Z

restore from backup to factory state and then flash again. You killed the section with WiFi module calibrations and most likely your MAC address does not match the sticker on the router.

ARManakhov · 2024-10-21T16:59:30.784Z

thx
btw after writing question i found KhetagAb solution

r33tom · 2024-10-22T04:00:12.977Z

so does that mean i can update using the official 23.05 firmware instead of snapshots?

or do i need to wait for next release?

LexOWRT · 2024-10-22T09:17:39.074Z

Just a public service announcement: I bought one last month and I bought one last week from the same seller on Aliexpress. First one that came in was an RD03/Winbond (fw: 1.0.47), second one RD03/ESMT. (Will edit this later to add the fw version they came with, but the Winbond one came with the right fw for owrt upgrading).

Last month I wasn't aware of the 7 boot brick, so I guess I'll have to get them both up to date properly. Will dig through here for a while, thanks for all your efforts!

victor186 · 2024-10-22T17:59:03.835Z

Offload don't make any change, bug occurred with and without offload enabled.

victor186 · 2024-10-22T18:01:09.893Z

I've changed the package and will test.
The CPU usage is higher, 50% CPU usage with NAT.

Lexeyko · 2024-10-22T18:13:37.266Z

add package - bridger.

My xiaomi ax3000t ( r27788-a475171e07 ) keeps the clients capped at 390 mbits for both rx and tx rate. Already tried to change the freq channel and mode.

Cthulhu88 · 2024-10-23T04:42:53.121Z

Are you talking about the 5 Ghz wifi bitrate? If so, on a single stream it caps at 433 (at 80 MHz width and AC mode).
