Update: In my case WIFI works again after disabling 802.11n. I added the option 11n_disable=1 to /etc/modprobe.d/iwlwifi.conf - now it looks like this:

# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system. When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac8021
options iwlwifi 11n_disable=1
