Hmm... if there is no other errors, then this problem is new for me.
Try fallowing  options:
- change encryption. If you use WEB you can disable encryption at all -
it is same. In case there is hardware enc., it may fail. (WEP isn't
encryption any more ;))
- try to reset wifi adapter. Unplug and plug it again.
- update firmware. If you can compile it, then use this one
