first:

uninstall firewall , iptables:

code:
sudo apt-get remove --purge ufw gufw  sudo iptables -t filter -n -l -v  sudo iptables -f  sudo iptables -x
second:

deactivate n-mode of driver (bug):

code:
echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf  sudo modprobe -rfv iwlwifi  sudo modprobe -v iwlwifi
third:

remove (not edit) wireless profile , create new 1 in "infrastructure"-mode.

fourth:

check:
code:
iwconfig  sudo iwlist scan  iwlist chan  rfkill list  dmesg | egrep "iwl|country|dell"
