It's not only when using wrong password. Even if a password is good and the network is connected hardware restart is requested. When this error appears packets are dropped and the network speed slows down. As a workaround you can add
options iwlwifi 11n_disable=1
to /etc/modprobe.d/iwlwifi.conf file. This slows network to 54MBit/s but it is stable, with no packet drops and hardware reset.
