According to the manual, it's the same. And I am sure I've reset my R600 once before using the same way. Is there a specific way it isn't working? (e.g. can't find it at 192.168.0.1? Login credentials not working?)
Have two R600's that I am trying to get connected to a ZD1200. As soon as they are added to the ZD1200 they upgrade code from 100.x to 9.9.x reboot and then both R600's become unresponsive. Cannot HTTPS or SSH to the AP, nor does it respond to ping. I do see the AP sending DHCP requests to the DHCP server (via DHCP debug).
Hmm, that's certainly an interesting problem. Factory resets should work, but remember that if you factory reset it *while* connected to your network, it's just gonna get immediately reprovisioned by the ZD.
You should be able to double check with the AP directly connected to a computer whether or not it shows up at its default IP.
