I need some help from you, I found problem that some clients cannot connect to AP( but some client can connect as normal). As I checked from logs, I see a lot of messages as below:
Nov 18 01:13:55.760: %DOT11-4-MAXRETRIES: Packet to client 0023.68be.1c88 reached max retries, removing the client
Nov 18 01:13:55.760: %DOT11-6-DISASSOC: Interface Dot11Radio0, Deauthenticating Station 0023.68be.1c88 Reason: Previous authentication no longer valid
Nov 18 01:13:55.763: %DOT11-4-MAXRETRIES: Packet to client 0023.68be.1c88 reached max retries, removing the client
After that I tried to reload AP and then it can connect as normal but I found the log that it roaming to another AP in the same SSID as log below:
Nov 21 08:52:12.147: %DOT11-6-ROAMED: Station 0023.68be.1c88 Roamed to 003a.99e6.6860

I've check from CISCO document, this problem may be from Radio Interference, so please help to investigate and find out the root cause that why some clients cannot connect to AP at that time and how to prevent this problem occurred again.
Thank you in advance.
