Which branch?  main or stable/14?

Where do you get the 300Mbit/s from?  Just the theoretical value?

Blessed are you.  Your radio environment must be very quiet that you
manage to get on a 40Mhz channel on 11g (or the AP is set to force now?)!

You are using TKIP which is not yet supported for crypto offload so either you
do not have hw_crypto enabled (which the newer firmware would) as well or you
are not getting reasonable throughtput as ampdurx would be automatically
disabled by LinuxKPI and it looks like from the next line of the
ifconfig output that it got (both RX and TX as it syas -ampdu; TX is disabled
on purpose in the current version).

Do you have any chance to enable/switch to CCMP on the AP?

What does:
sysctl compat.linuxkpi.80211.hw_crypto compat.linuxkpi.iwlwifi_11n_disable compat.linuxkpi.iwlwifi_disable_11ac
show for all three?

And once you are associated and have some traffic, what does
sysctl compat.linuxkpi.80211.wlan0
say?

Nowhere.  It can be ignored.  https://wiki.freebsd.org/WiFi/Iwlwifi/#Frequently_Asked_Questions
