I have a similar problem. Out of the box, the AP setup as documented. on initial reboot, I couldn't login. After several retires, I shutdown the "new" ap and restarted my home AP which is also the CBW240. I come to find out that it appears the Username and Password are case sensitive. For the new AP, I failed to explicitly copy the case of the username correctly. I have to reset the new AP. I have spent a couple of hours resetting according to the documentation using the reset mode button. I have tried varying when to release the mode button but no matter where I release the button, the configuration is not reset and I do not get the default startup ssid.
