Hi, did you manage to sort out your rbr750 with a TTL to usb connection? im also trying this method but I cannot get any communication from the router and putty, I suspect this is due to the fact...

im also trying this method but I cannot get any communication from the router and putty, I suspect this is due to the fact I don’t know which pin is which.

This document shows the pins on an older Orbi. Maybe the 750 pins are in the same orientation?

The RS232 serial pins are not obvious on the internal photos of the 750 product on the FCC web site (unless that is them at the top of image #4)

    Nope one is cream and the other is white. I too got a little confused but it’s what I had to work with.
