...  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.

Huh. I also have that BCM4318 card, but not PCMCIA.

These past few days I seem to have had some "success" by simply
putting a 60 second sleep in my bootup scripts before bringing up
my wlan0 interface. (Ie. I haven't been getting any deauths after
doing this.)

Interesting. I assume you are using wpa_supplicant so can you make a
supplicant log of that with and without the 60 second sleep.

The same thing happens even without wpa_supplicant. Simply doing "iw
wlan0 connect BlablaAP" .... it will still mysteriously deauthenticate
after a minute (usually).
