Unfortunately I have not been able to find any reset button on this one. It is an exterior AP and even when I took apart the exterior case I didn't see any reset button. I think the AP is stuck in some kind of NTP loop but I have been unable to log in via the console port. I keep getting a series of console messages after the main boot messages scroll through:
NTP will run in 10 seconds!
Run NTP client ...
NTP will run in 10 seconds!
Run NTP client ...
NTP will run in 10 seconds!
Run NTP client ...
timediff=0
NTP will run in 10 seconds!
Run NTP client ...
timediff=0
NTP will run in 10 seconds!
and this continues over and over. I have tried to login to try to command the AP to reset to factory defaults but it doesn't seem to let me, unless I have somehow gotten the password wrong. The looping NTP message intermixes with the hyperterminal console and makes it very difficult to get the login info in there (I had changed the password when setting up the AP originally).
Is it possible to reset the unit without login via the console port? I don't think there is but thought I'd ask. I pulled the AP from service and installed a new one, set it up the same not knowing what the issue was on the original, and now I have 2 DAP3690s with the same problem. I think I may pull the new one which should definitely have the password I have written down assigned to it and try resetting that one, and maybe I can login to that one. Otherwise I may be taking apart the AP again looking for some way to reset it.
