I have many legacy ap2660 devices, and they are set to get a dhcp address, then we hard code the wireless controller (via telnet). I have found that many of these devices do not let me log into them with the default admin / new2day credentials. We have not changed the password, and I have held the red reset button down for about 30 seconds. Even after that I still cannot log in. Are there other credentials that I can use to log in, or is there another way to connect to these to perform administration tasks?
