The driver iwlwifi usually creates an interface wlan0, not eth1. Check:
ifconfig
If you have no wlan0, something else is wrong and we should diagnose and correct it first:
dmesg | grep iwl
rfkill list all
If there is a wlan0, then the correct sequence is:
sudo ifconfig wlan0 down
sudo iwconfig wlan0 mode master
Please note that not all wireless device and driver combinations can be switched to all modes. Please see: http://wireless.kernel.org/en/users/Drivers/iwlwifi
AP mode (experimental; only on some devices/firmware versions)
Have you checked if your ethernet deive id is not eth0?
try iwconfig command in terminal to check your ethernet device id.
