Hello, I have a 2504 WLC controller. I have tested all the stable and intermediate versions of the controller software like (AIR-CT2500-K9-8-3-150-0.aes; AIR-CT2500-K9-8-5-140-0.aes ; AIR-CT2500-K9-8-5-151-0.aes, as well as their bundles). I have 7 APs (5 * 1572 (newer models) and 2 * 1552 (older model)). When I make MESH only from the new APs, everything works smoothly. When I add one of the older APs or two of them, the mesh and the client still work smoothly, but I lose a ping from the outside to the AP and lose the monitoring (from WLC I still can ping APs). These are the Global Telnet SSH options enabled, but when an old AP join the MESH, after 5-8 pings go trough I lose pings at the same time by all. Please help me.
