Greetings -- I've just picked up an 881 and 2 521's. I have the 881 setup fine with the CP Express. No problem there. Now I'd like to get these 2 APs running but I haven't been able to figure out the first thing. I've attempted using the CCA to discover to topography but the 881 isn't supported. The CCA asks for my level 15 access, which I enter, then it asks for username/password for the "Admin" realm. I know of no such "Admin" realm. I've tried every user/pass combo I can think of. Also, when I plug these AP's into the 881 and power them up, the LED's eventualy alternate ethernet:green radio:amber and the main LED alternates green/red/amber which leads me to believe that there's something basically wrong with the AP's. Any help would be appreciated.
