I just configured my MikroTik hAP ac2 to operate in bridge mode and it seems to have lost its mind or developed a split personality syndrome.
With my browser I connected to the default http://192.168.88.1 set up address and configured it as a WAP, i.e. I chose "bridge mode."
I created a new SSID and set the initial administrative password and passphrase for WiFi auth. While I was attached to the MikroTik via https://192.168.88.1 I noticed it had received a IP address lease from my dhcpd server so I left that alone. I clicked on the "check for RouterOS updates" button and nothing happened. It works as a WAP but there are two problems.
It has two SSIDs, the factory one and the one I created. (Both work.) I see the device talking to my Debian dhcpd server and it's got a lease but I cannot connect to it.

Update:
So I managed to do a factory reset and was able to upgrade to the latest, stable RouterOS. I configured the device the same way I did yesterday but the results are the same. I still have a phantom device on my network that does perform well as a WAP, but I can't connect to the admin http interface.
