figured out how to disable iwlwifi 11ac:

echo "options iwlwifi disable_11ac=1"  >>  /etc/modprobe.d/iwlwifi.conf
root@n2linuxvm:~ # cat /sys/module/iwlwifi/parameters/disable_11ac
Y

5Ghz, channel 48, channel width: 20 MHz, 802.11n/ac mixed mode in router, but 11ac is disabled in station.
This should make the wifi interface associated at 802.11n only at 5Ghz, channel 48, channel width: 20 MHz

5Ghz, channel 48, channel width: 80 MHz, 802.11n/ac mixed mode in router, but 11ac is disabled in station.
This should make the wifi interface associated at 802.11n only at 5Ghz, channel 48, channel width: 80 MHz
