    Hello, can this router work in mesh with AX3000?

    1. Yaroslav

      No, it can’t

      1. Hector

        Hello, Could we have an explanation? I did not know that the devices are not mesh compatible with the whole range.

        1. Yaroslav

          We cannot explain because we are not representatives of Xiaomi

        2. Ian

          Yes but only if both routers run Chinese firmware. If your AX3000 runs global firmware (either you brought it from an international Xiaomi authorized dealer, or you flashed the global ROM on your China-market AX3000) then you’re out of luck, as the Chinese-market AX1800/RM1800 (the black tower router) only has Chinese firmware.

      2. Dmitri

        Yes, it’s working fine. And you don’t need to have CN firmware on any of it. I’ve used it with global AX300. It connects to the mesh automatically after resetting. If not – push the “mesh” button on AX3000.

    2. Justin

      Mine does mesh with AX3000 no problem.

    Will the RM1800 receive more updates?

    1. Yaroslav

      We don’t know – it depends only on developers.

    Any english rom?

    1. Yaroslav

      If there’s no English ROM at official Xiaomi Channel, you couldn’t find it anywhere.
