Upgraded our WLC 4404 from 6 to 7 so we could upgrade some WAPs to 3500i. After upgrading all 8- 1120 and 1240s connectivity were lost.
We reverted back to OS 6 and all came back to Controller
WLC Software version = 6.0.199.4
WLC Emergnecy Image Version = 7.0.235
WAP Config
Software version 6.0.1994
Boot Version 12.3.2.4
IOS version 12.4(21a)JHB1
Mini IOS version 3.0.51.0
Our vendor states this should be a compatible mix and they are also checking as to why it is not working as planned. Because they are charging for this I thought I would check myself or at least give them something to start with
Any ideas?
