>Environment:
fresh system,no custom kernel.but now I can't get it because I rebuild the kernel with the patch.
>Description:
I think the hardware is ok because I can use it in Win7. And in Freebsd 9.1,it works for sometime,but sometimes after system reboot or I plug out & plug in the card it my unusable.on the console it emmit:
"run0: wcid=xx out of range" where xx is 91,87 and etc.
it seams the wifi is connected because ifconfig wlan0 cmd shows the right ssid and bssid ,but inet addr is always 0.0.0.0
>How-To-Repeat:
I plug out & plug in the card some times
>Fix:
thanks for PseudoCylon <moonlightakkiy@yahoo.ca>'s help, his patch solves the problem.
Reboot or re-plug-in shouldn't be a cause of the problem. Receiving an
association ID larger than device's max (64) is the problem. You must
be using a high-end AP. Reboot or re-plug-in initiate re-association
and just happen to receive a large association ID.
