En una nueva instalación, hice esto:
primer cambio a raíz:
nano /etc/modprobe.d/intel-5300-iwlagn-disable11n.conf
haz que se vea así:
#options iwlagn 11n_disable=1
options iwlagn 11n_disable=1 swcrypto=1
Reinicie y / o en una terminal haga algo como lo siguiente
root@main:/home/bildr# modprobe -r iwlagn
root@main:/home/bildr# modprobe iwlagn
root@main:/home/bildr# killall nm-applet
root@main:/home/bildr# airmon-ng start wlan0
Found 4 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!
