   You are missing hostapd package: #58

   @dca00 Really. hostapd when the error clearly says iw and iwconfig. I am getting the same error and am sure beyond reasonable doubt that I have hostapd installed

   It’s been a very long time since I created this issue and I’ve since sold the previous laptop and switched to Mac. From what I remember, I managed to get it working by turning it into a shell script and running it with sudo.

   What command did you use? Is your network interface actually wlan0? To double check, you can use the ifconfig command in your shell.

   I got it to work

   It’s been a very long time since I created this issue and I’ve since sold the previous laptop and switched to Mac. From what I remember, I managed to get it working by turning it into a shell script and running it with sudo.

   What command did you use? Is your network interface actually wlan0? To double check, you can use the ifconfig command in your shell.

   I realized my network interface was actually not wlan0 to start with but even that did not fix it, it led to another error that said the device was busy. I then found out I could turn off the network interface with

   nmcli radio wifi off

   then: sudo ./linux-router.sh --ap wlan0 MyAccessPoint -p MyPassPhrase
   Replace wlan0 with your network interface

   this would successfully create the ap/wireless hotspot

   then bring wifi back on with:

   nmcli radio wifi off

   Connect to the wifi network and you are able to share your internet. Its a long process but it works.

   Managed it by installing which package. Shell script executes "which iw". If command which returns error, then script thinking iw package is not installed and prints "Can't use 'iw' to operate interface..." and goes further.
   Dear developer, please add which package to the list of dependencies.
