  2. Thanks for this guide! I've got an RBM11G and want to place ROOter on it. Going by the post, it looks like I need a USB to serial adaptor, but I don't know where to hook it up on the RBM11G. Can RouterOS be replaced without needing the USB to serial adapter? Cheers!

    1. Yes. IIRC, all you have to do is replace steps 7&8 with holding the set button while you plug in power. After about 30 seconds the LEDs start flashing, indicating it is now attempting a network boot.

  3. Daniel,

    I've got a similar configuration (RBM11G + MC7455). The modem gets detected and works in MBIM protocol. I don't know what to do next - it looks like it works in direct ip mode. How to force it to work?

  6. You forgot the part where the Mikrotik license needs to be backed up so this can be reversed in the future.
