We have a new device to work with -  LibreMesh is working on the Xiaomi MiWiFi 3, thanks to Chen Minqiang (ptpt52), who made a LeDe firmware, and P4u and Gio who got the libremesh version.

Even though the mt7620 (2.4Ghz) is known to be a bit flaky, the 5Ghz should be good. And until LibreRouter is available, it seems to be the only available dual band solution (at least in Brazil).

So here are the steps to install it:

- Follow these steps to get ssh/dropbrear access: https://wiki.openwrt.org/toh/xiaomi/mir3#to_get_sshdropbear_access (don't forget to downgrade the firmware before)

- Download libremesh rootfs and kernel files from here:

- Copy these files over scp to the router:
scp lede-ramips-mt7620nand-miwifi-r3-squashfs-kernel1.bin   root@192.168.15.1:/tmp/
scp lede-ramips-mt7620nand-miwifi-r3-squashfs-rootfs0.bin   root@192.168.15.1:/tmp/

- login through ssh:
ssh root@192.168.15.1

- type in the commands (from chen's instructions https://github.com/ptpt52/lede-source/issues/1)
nvram set flag_last_success=1
nvram set boot_wait=on
nvram set uart_en=1
nvram commit
mtd write /tmp/lede-ramips-mt7620nand-miwifi-r3-squashfs-kernel1.bin kernel1
mtd write /tmp/lede-ramips-mt7620nand-miwifi-r3-squashfs-rootfs0.bin rootfs0
reboot


And it should be meshing!

Cheers
