Using the Function Keys for wifi

[freestyler]

I am trying to make use of the keys <Fn+F2> to control my WIFI, after creating a file in the path "/etc/acpi/eee-wifi-on-off.sh". But I am getting the error as "Error writing /etc/acpi/eee-wifi-on-off.sh: Read-only file system". Please help me to fix this issue.

You have to switch to root to write to that folder. For example, "su kate /etc/acpi/eee-wifi-on-off.sh".

But will I be able to use the FN+F2 when I'm not root?

Try it and find out. My guess is yes, if you have it configured correctly.
