WLAN falling out of the AP group

Question

Just wondering if anyone has encountered this before.  Got a call stating that devices were not working on the wireless network. Doublechecked all settings on the WLC and everything looked good except that under the AP Groups, WLAN tab, the SSID was no longer showing up as being added to the group.
When i tried to add it back, i got error message stating that it already existed. I had to delete the WLAN and rebuild it, and then add it back to the AP group. After that, devices came back online immediately.
Model - NMEWLC-12
code - 7.0.240.0
Ive had this happen on two different controllers running the same code. Anyone seen this before?

Hello,
As per your query i can suggest you the following solution-
The issue may be because of the number of clients per WLAN or per radio.
Configuring Maximum Number of Clients per WLAN (CLI)
Step 1 Determine the WLAN ID for which you want to configure the maximum clients by entering this command:
show wlan summary
Obtain the WLAN ID from the list.
Step 2 Configure the maximum number of clients per WLAN by entering this command:
config wlan max-associated-clients max-clients wlanid
Configuring Maximum Number of Clients per AP Radio Per WLAN (CLI)
Step 1 Determine the WLAN ID for which you want to configure the maximum clients per radio by entering this command:
show wlan summary
Obtain the WLAN ID from the list.
Step 2 Configure the maximum number of clients per WLAN by entering this command:
config wlan max-radio-clients client_count
You can configure up to 200 clients.
Step 3 To view the configured maximum associated clients, use the show 802.11a command.
Hope this will help you.
