Hi,
I have a Lenovo X240 with an 7260AC (I upgraded it myself, but it is Lenovo
branded). This weekend I'm at an event where I run the Wi-Fi myself with
Cisco gear, mostly 2602i. I've had several instances only today where the
microcode hangs:

At this point, my Wi-Fi is usually so hosed that I just have to reboot;
SSH lags etc., and then after a while all networking just hangs.
Now, a different question is why Linux insists on using 2.4 GHz even though
it's super-congested and the APs have turned down the power significantly
(you can see it's asked to send at 4 dBm in the log there). But that's a
different and much broader story :-) (I don't have band-select on.)

Not sure. This question should go to the supplicant folks.
