Joining Cisco aironet air-lap1142n-a-k9 to 2504 WLC

[icebreaker17]

Hello,

Please i need help about the following issue:

I upgraded Aironet air-lap1142n-a-k9 from autonomous to lightweight in order to join a 2504 WLC.

The firmware i installed on AP is c1140-k9w8-tar.153-3.JC and on WLC the software system is 8.1.102.0.

The main problem after upgrading that AP couldn't find the controller and keep displaying on CLI :Translating "CISCO-CAPWAP-CONTROLLER"...domain server (255.255.255.255)".

I already joined 5 APs of AIR-CAP702I-E-K9 to the  controller but this one its not working .

Please any help?

The 1140 has a Regulatory Domain of "-A" while the 702 has a Regulatory Domain of "-A".  I would deduce the WLC is configured for "-E".  

On the WLC, post the complete output to the command "sh sysinfo".

As suspected, the 702 has a Regulatory Domain of "-E" which matches the country of Lebanon.  The 1142 has a Regulatory Domain of "-A" and this is incompatible with "-E".  

However, I have seen many cases where a "-A" AP can join the controller specified with "-E" but the 802.11a radio of the "-A" AP will be "Admin Down". 

On the WLC, can you please post the output to the command "sh time"?

Two options: 

1.  Convert the "-A" AP to autonomous; or

2.  Get another controller:  Cisco Mobility Express Bundle

[icebreaker17]

I need the Ap to work under WLC not standalone...

is there any way to turn it round?

[Leo Laohoo]

is there any way to turn it round?

If this has to work with a controller then look at the Cisco Mobility Express Bundle.  By purchasing two (2) APs, you get a free WLC.  

Otherwise, I ain't going to post a solution which will, effectively, break the law in your country.

look the error changed after i corrected the date and time:

[Leo Laohoo]

Does this network have a valid NTP server.  Please use the NTP server to let the WLC get the correct time and date.

[icebreaker17]

i already configured NTP server on the core Switch.please have a look

[icebreaker17]

Dear,if u have a solution other buying a controller please post it

[Sandeep Choudhary]

There is no other solution. Either you need to buy a new AP which works in LB regulatory domain or buy a Cisco Mobility express bundle as mentioned by LEO.

No NTP server and the time and date are incorrect.  This could be another reason why the AP won't join.
