This problem can be for many reasons, security key in your wireless profile, interference, poor signal, channel overload, access list restriction.

Have you changed anything in your configuration? Security changed from WPA PSK to none? And all clients have "remembered" settings for the old configuration and computers tries to connect with password?

I'm seeing the same issues, on 2 out of 10 in my upgrade test group.

I've confirmed that the credentials are correct.
Ultimately she did get the phone connected,

09:31:01 wireless,debug wlan1: 68:84:70:3F:75:90 attempts to associate
09:31:01 wireless,debug wlan1: 68:84:70:3F:75:90 not in local ACL, by default accept
09:31:01 wireless,info 68:84:70:3F:75:90@wlan1: connected, signal strength -74
09:31:32 wireless,info 68:84:70:3F:75:90@wlan1: disconnected, received deauth: authentication not valid (2)

Repeated many times before

09:48:07 wireless,debug wlan1: 68:84:70:3F:75:90 attempts to associate
09:48:07 wireless,debug wlan1: 68:84:70:3F:75:90 not in local ACL, by default accept
09:48:07 wireless,info 68:84:70:3F:75:90@wlan1: connected, signal strength -86


I hear similar tales form other customers, primarily on 6.42rc6 not 6.42.1

I'm also having this issue on 6.42.6. Signal strength -63, so not too weak. Sometimes I also get deauth due to MIC failure (14), for the same device

This is mostly fixed for our customers.

Were using the setting in the script in post one of "Wireless woes and how to fix em :)"

It is caused by congestion.
When reported we look at the network; resolve if internal (such as getting those stupid Direct print printers on the network instead of competing with it}.
If not internal do a scan and determine the best channel; then modify the scan-list in order of preference.

It's a lot better in 6.42.3 as well, haven't tested newer.
