# Keep WiFi adapters awake. Power saving (the adapter dozing between
# packets, and the USB port suspending an idle dongle) is what makes
# cheap dongles like the Realtek RTL8188CUS drop or stall a connection.
# Both are ordinary software settings, so nothing here can harm the
# hardware: the cost is a fraction of a watt.
# Radio power save off on every WiFi interface as it appears.

# No USB autosuspend for the common RTL8188/8192 CU/CUS/RU dongles.
