# wifi-sim.sh — Virtual WiFi environment for development & testing
|

#

# Creates 3 dummy networks using mac80211_hwsim + hostapd:
|
|
||||||
# - FreeWifi (open, strong signal, ch 1)
|
|

# - OfficeNetwork (open, medium signal, ch 6)
|
|

# - HomeNetwork (WPA2, weak signal, ch 11)
|
|

#
|

# Usage:
|

# sudo ./wifi-sim.sh start
|
|
||||||
# sudo ./wifi-sim.sh stop
|
|

# sudo ./wifi-sim.sh status
