I have a problem with my vWLC and AP 1602. I have the vWLC 1 with 7.4.121. software in cloud and 3 AP's 1602 and it is working fine. And I tried to make a Backup Controller vWLC 2 on Local network. I downloaded the cfg file, changedn the IP adress and uploaded on my new vWLC 2 with 22.214.171.124 software. The vWLC 2 picked up the VLANs and it has same configuration like the vWLC 1 but it can't see AP's..
Did anybody have a similar problem and managed to fix it?
When I checked statistics of "AP join", I saw that the vWLC 2 reciveid requests from AP's and then vWLC 2 sent response to AP's but still AP's didn't join to vWLC 2. I think that the problem is new version of software(126.96.36.199) on my vWLC 2 whose software supports 15.3.3 IOS version of AP's , but on my AP's is still 15.2.2 version ( because the software 188.8.131.52 on my vWLC 1 supports that version of AP's IOS).
