Post the complete output to the following commands: 

1. WLC:  sh sysinfo; 
2. WLC:  sh time; 
3. AP:  sh version; 
4. AP:  sh ip interface brief

NOTE:  Do not attach screenshots because they are difficult to read in some cases.  Try copy-and-paste the output into a text file and then attach it to the response.
