I am using an 851W configured with WPA-PSK and TKIP. I am getting an awful lot of messages in the log stating that a client has disassociated because it was leaving the BSSID, then the client immediately reconnects. I have duplicated this behavior with two different 851W routers and four different client adapters (Intel 2200BG, Intel 2915ABG, Cisco AIR-CB21AG, and Linksys WPC54GS). It occurs with optional WPA key management as well as mandatory, and cipher suite TKIP+WEP and TKIP alone. Any ideas? Thanks very much.
What is happening in your case is that, the client is getting disassociated and then again tries to reconnect. This can happen if there is a authentication failure. Check if the authentication parameters are configured correctly on the client and AP. Check if the WPA encryption keys match on the AP and the client.
I have verified that the WPA keys match. I have not been seeing any authentication failures in the log, however today I see an authentication failure from one of my laptops at a time when the machine was 15 miles away, and didn't have the wireless card in... Weird, really.
