Another excerpt from dmesg:

hi,
can you capture the whole dmesg from association to disconnects? I'd like to
see what's going on the whole time.
Thanks!

God damnit, okay. So it /looks/ like a single bit corruption of the RSC, which
causes the AES-CCM code to consider everything afterwards to be a replay
attack.

Yeah, that's a beacon miss. I'm not sure why that is yet.
You can try -bgscan -powersave just to enforce things, but I don't know if it's
going to help all that much. The PN corruption is just very dam

But I already have -bgscan disabled in rc.conf and powersave mode seems to be
turned off:

Hiya,
So the beacon miss / TSFOOR is the driver side. I can go take another look at
fixing that up.
The CCMP replay attack thing - that we need another NIC to sniff the air in
monitor mode and try to

I upgraded the system from 10.3 to 11 and the network interface isn't
created any more for this TP-Link / N600 card:
> run0 on uhub3
> run0: <1.0> on usbus3
> run0: MAC/BBP RT5592 (rev 0x0222), RF RT5592 (MIMO 2T2R), address
60:xx:xx:xx:xx:xx
What changed in 11?

Hi,
Since 11- there is no network interface for wireless devices. To list
wireless devices, please use: "sysctl net.wlan.devices". To create network
interface, use: "ifconfig wlan0 create wlandev run0" (or via /etc/rc.conf,
but I don't remember exact command).
Thanks!
