600mb/s on 5ghz(1800ax card) at 09 metre of distance with a wall (25cm concrete)
Test this, its work for me for more than 24 days with 3 or 4 reboot without big issue -- openwrt-23.05.3-ramips-mt7621-haier_har-20s2u1-squashfs -sysupgrade.bin ---
I got 'image check failed. Device, sim,simax1800t not supported by this image....' when using openwrt-23.05.3-ramips-mt7621-haier_har-20s2u1-initramfs -kernel.bin
so I flashed the SIMAX1800T image, i.e. openwrt-23.05.3-ramips-mt7621-sim_simax1800t-squashfs-sysupgrade.bin and it fired right up.
The first attempt to update broke. I downloaded the files using TOH and it provided links. For a working installation, I had to use tftp installation. And specifically download the Haier kernel and sysupgrade packages from downloads.openwrt.org.
My device it is openwrt versio of this link
flashed with TFTP from server 192.168.1.254; Router is 192.168.1.14 (openwrt-23.05.3-ramips-mt7621-haier_har-20s2u1-initramfs-kernel.bin)
After that I flashed my EDUP EP-RT2960 AX1800 with openwrt-23.05.3-ramips-mt7621-haier_har-20s2u1-squashfs-sysupgrade.bin >>it works
NOTE: disable the firewall & use Tftpd64 as server

report that as addendum to wiki page or ask to edit yourself via documentation talk topic.
I flushed my one first with sim, as haier refused, than flush it with haier ( may force it).
Firmware on that route was based on sim( showed as alias in the dump of firmware mtd).
BTW any on know how to get the temp on cpu and wifi on that router?
What firmware do you have?
Its a stock firmware by fenvi
Can you post step by step process? Did you do it using gui or other method?
Hi pablo. I bought same hardware but it’s stock firmware (which says wifi6) . I am not able to flash openwrt through GUI. It says incorrect verson. Can you help me with steps? I also bought usb ttl cable just in case.

not sure if steps 4 & 5 are valid for this device too.
Sorry, but mine was already with openwrt version. So I can't help you.
was able to flash x wrt firmware XWRT WR1800K-AX NAND through GUI. Later flash openwrt firmware.
I'm waiting for your same model. Exactly, which version of xwrt and openwrt did you flash?
Open xwrt and look for WR1800K-AX NAND. First flash
x-wrt-24.04-b202407010752-ramips-mt7621-xwrt_wr1800k-ax-nand-initramfs-WR1800K and then sysupgrade.
