AP1121G - can't set to autonomous

Unanswered Question


We bought WLC-2106 and two AP-1121G.

AP-1121G was with autonomous software, so I downloaded software and

switched it to

lightweight mode, but it doesn't work.

I see in controller log :

*Oct 13 09:43:35.437: %LWAPP-6-DISC_RESPONSE_SENT: spam_lrad.c:1327

Discovery Response sent successfully to AP 00:21:55:74:af:82

*Oct 13 09:43:28.916: %DHCP-6-SCOPE_NOT_FOUND: dhcpd.c:167 Dropping

packet from (unable to match to a dhcp scope)

*Oct 13 09:43:28.915: %DHCP-6-SCOPE_NOT_FOUND: dhcpd.c:167 Dropping

packet from (unable to match to a dhcp scope)

Then AP reboots. management interface address.

dhcp.conf for AP:

option space ciscoap;

option ciscoap.vci code 43 = text;

option ciscoap.wcip code 60 = string;

host ap {

hardware ethernet 00:21:55:74:af:82;


option ciscoap.vci "VCI string" ;

option ciscoap.wcip C0:A8:16:12;


So I decided to return AP to autonomous mode.

I downloaded image, put it on ftp.

AP got it, rebooted, but seems it is still in lightweight mode- I see

the same messages on controller log and can't reach AP over http.

Could you tell me how can I

return AP to authonomous mode?

Is there any howto for adding AP to wlc2106?

thank you!

I have this problem too.

According to the log it’s not getting the DHCP server IP address . Please check if proper network DHCP server scope is defined and AP s connected to proper port.

There are many methods to convert the Lightweight to autonomous.


Please check the below link for conversion:-
