Client unable to connect AP with MAC filtering

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%DOT11-6-DISASSOC: Interface Dot11Radio0, Deauthenticating Station 0023.68be.1c88 Reason: Previous authentication no longer valid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

Nov 21 08:54:33.855: %DOT11-6-ROAMED: Station 0023.68be.1c88 Roamed to 003a.99e6.6860

Nov 21 09:04:34.495: %DOT11-6-ASSOC: Interface Dot11Radio0, Station  0023.68be.1c88 Reassociated KEY_MGMT[NONE]

Nov 21 09:04:39.097: %DOT11-6-DISASSOC: Interface Dot11Radio0, Deauthenticating Station 0023.68be.1c88 Reason: Sending station has left the BSS

Nov 21 09:04:39.103: %DOT11-6-ASSOC: Interface Dot11Radio0, Station  0023.68be.1c88 Reassociated KEY_MGMT[NONE]

Nov 21 09:04:42.309: %DOT11-4-MAXRETRIES: Packet to client 0023.68be.1c88 reached max retries, removing the client

Nov 21 09:04:42.309: %DOT11-6-DISASSOC: Interface Dot11Radio0, Deauthenticating Station 0023.68be.1c88 Reason: Previous authentication no longer valid

Nov 21 09:04:42.315: %DOT11-4-MAXRETRIES: Packet to client 0023.68be.1c88 reached max retries, removing the client

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.
