Hello!
We have a problem with AIR-LAP1142N access points.
AIR-LAP1142N-E-K9
Version 12.4(21a)JA
LAP's are not assotiated with controller yet.
They get the ip address via dhcp, they are reachable by icmp.
When I try to telnet, I get
Password required, but none set
Is there any chance to get access to them without using serial port?

1. in general the AP do not responmd to telnet or ssh, but this depends on the state of the AP and the controller settings
I am not sure what state a Defaulted AP is in ...
2. Normally the AP must resolve, via DNS, the record cisco-capwap-controller.YOURDOMAIN.COM
så make sure you have this in your DNS for that AP (i.e. might be the DNS that the DHCP provide with the IP)
But this link to CCO, provide you info on how DHCP option 43 can be used.
(I find the DNS record much more suitable and easy to use)

thank you for your answer!
can you clarify how can I do it exactly?

LAP AP's dont run SNMP ...
sorry
just press the mode button to reset to factory defaults, and your LAP AP can retry to join the controller.

The thing is, that LAPs don't know, which controller they need to join to.
The controller is situated in another L3 segment.
I need to tell them, what controller ip is.
If I reset them,will I be able to get remote access to them via telnet/ssh ?

1) In general, is it normal situation for LAP 1142-N to answer "Password required, but none set"
to the remote telnet session?
2) Is there any dhcp option, that can inform the LAP about WLC ip address?
