Does anyone know why these might occur? What type of encryption are you using? If it is a re-keying type such as TKIP, what is the interval? You should find that on the setup page of the access point. BTW, your mailer is set up strangely. I get your address when I do a plain Reply, but a Reply All from Thunderbird only got the b43-dev mailing list. I had to add your address manually. I also added the linux-wireless ML to the reply as some of my questions are more likely to be answered there. Larry
