Ever since I upgraded to the 4.10 kernels (I don't think this behavior existed in the 4.8 series), after I startup my laptop (either from cold boot, or from standby), my wlan0 interface keeps deauthenticating 19:24:29 kernel: wlan0: deauthenticating from 00:11:22:33:44:55 by local choice (Reason: 3=DEAUTH_LEAVING) usually exactly 60 seconds after it authenticates/associates (to my open wifi access point), but not always 60 seconds after -- sometimes it happens in less than 60 seconds. Although, if it somehow manages to pass the 60 second mark without deauthenticating, it remains stable -- unless I decide to /etc/init.d/net.wlan0 restart it :s. I'm not sure what makes makes the deauthentications suddenly stop, but after various incantations and module unloading/reloading and a fair amount of cursing, or possibly just waiting some random amount of time, the problem goes away for the day ... and returns the next day when I boot up again, and I have to go through this torturous process all over again, of praying and restarting my wlan0 interface.
When you file a bug report such as this, you need to provide information regarding what specific card you have. The appropriate stanza from "lspci -nn" has that information.
I do not normally run a b43 wireless NIC, but I did pull out an ancient laptop that uses the PCMCIA version of a BCM4318 with PCI ID of 14e4:4318. Running kernel 4.10.0, I do see periodic drops. My period is 120 sec and the drop is a reason 7, not reason 3 as you see. Another difference is that I see the drops with kernel 4.8.0 as well. With the earlier kernel, the drop period is closer to 60 sec, but it is not as regular. I will be checking even earlier kernels to see if I can find a "good" value for bisection.
