Is there something else to go along with that? Seems like I'm not getting
info you need with that one.
It would log to console and may show up in a log file or dmesg.
OK.. now for something *new*.
To make this reply even more confusing. I noticed while testing that
my 11ac connection quietly drops back to 11ng and/or even 11g when I'm
right in the middle of documenting things!! At least according to
ifconfig. When I run a speed test, I'm clearly not on 11g.
I tested this a bit more, and when ifconfig initially says I'm on 11ng
I get corresponding speeds. If I get connected with 11ac and ifconfig
later shows it 11ng etc. I still get 11ac speeds. 300+ mbit.
Below see reported 11g yet 300+ mbit speeds.

@adrian, this smells like a ieee80211_node_txrate gone wrong in
ieee80211_rate2media() or some place around this?
I further assume this has to do with IEEE80211_RATECTL_STATUS_FINAL_RATE
not being used anywhere as feedback and net80211 having no idea what
happens in the TX path otherwise on firmware based drivers?
I wouldn't mind seeing an 11a or 11an there if no 11ac but an 11a
channel and an 11g mode seems wrong.

If in doubt check the
sysctl compat.linuxkpi.80211.wlan0
as well, which is closer to what firmware reports back to iwlwifi and
LinuxKPI for now.
