# This will patch the wifi-wpa-setup file of the wpa_supplicant module to allow spaces in SSID's and Passwords.
# While I don't think spaces in passwords will be an issue, I figured it couldn't hurt to add that in as well.
#
# The wpa_supplicant module KMFD's Mod Hub has now been updated with this fix.
