Using a 4400 Wireless Controller and WCS how do you upgrade the LWAPP IOS on Access Points to the latest version or is this even necessary? My LWAPP access points are fully functional 1131's and converted 1230's, but I would like to know what the procedure to update ios's are when a new one comes out. Do these automatically install when you update the controller software or do I need to download new IOS periodically and copy it to the controller or WCS, etc? What do you think?
When a Lightweight AP is connected to the WLC it has the same Version as the WLC. For example if the WLC is running 126.96.36.199 the AP is running 188.8.131.52. If you upgrade the WLC to a new version the AP's are upgraded at the same time. There is no need to do anything with the AP's themselves.
