I have burned OpenWRT onto MR-3020 and got it working.
Unfortunately, to operate this device, I was required to connect it physically to the computer by single ethernet port called eth0.
After that I am trying to up wireless network, connect via it and then reassign eth0 to wan. All time on this way I am loosing connection to the device. The problem is that I am not understanding, what are
wan? Looks like these are entities of different classes or not?
What are rough steps of this process?
