Help: some error message on Cisco AP

[atc]

1. Deauthenticating Station xxxx.xxxx.xxxx Reason: Sending station has left the BSS

Under what condition will the AP print this? I can image that if client send out Disassociation or Deauthentication, AP should print this. Is there any other reason can cause AP print this?

2. Warning Packet to client xxxx.xxxx.xxxx reached max retries, removing the client

I heard that if there is heavy interference, this would occurs. But when I did TCP/UDP endurence test with heavy traffic within a clean environment with only the test AP and the client, the AP still have this message. Will heavy traffic cause AP print this?

Hi Junming,

both massages may be caused through RF issues.

What is the max. distance between the AP and the client? What is the sending and receiving power set to?

If you have lets say 50 mW sending adn 50 mW (17dBm) receiving power while the Ap and the client are only one or two meters waway from each other this might cause this.

If the AP and the Client are standing beside try 1 mW or 2 mW (-1 or 2 dBm).

Have a look if this resolve the problem!

Best regards,

Frank
