another write

What different between them?

Oh, I see. Do both models show PoE out on port 10? Otherwise, I’m not sure what the difference would be. That model has been around a while.

R2 is newer. But the same hardware…

Ok, i have one more quetion))
when i try to flash r2 by openwrt - i have error about the absence of a partition firmware, but router without r2 flash very well?
