I got a new MikroTik RBLHG-2nD-XL with OS: RouterOS v6.40.9.
The default IP is 192.168.88.1.
Some of the instructions to load AREDN software for this device may need to consider an extra step to change the default address on the device, or the PC network address.
Having said this, I have not been able to get the AREDN firmware to stick even getting the addressing correct.
I can get to the initial AREDN screen sometimes, but the node returns to its MikroTik fw after a reboot.
I've tried the 3.19 and the nightly build 1022.
