From the log it appears you're sending+receiving wep-encrypted frames. They keyid is the same and since you're receiving frames I have to assume the key matter is correct as otherwise the h/w would drop the frame. You can verify this by feeding the key into wireshark to check if the frame contents make sense. I'm out of ideas. About the only thing I can suggest is you setup a different ap w/ the same wep key and see if things work. If so then you know it's something this ap is doing. I can't recall when I last tested wep on HEAD but I'm pretty sure it works. I will re-test that when I get a chance. Sam
