Wireless NIC Power Settings

Wireless NIC cards are powered in two ways:


Desktops plugged into the wall

Laptops running on batteries

Standard settings Machines often have a client name that distinguishes
them on the WLAN, and in most cases this name is set by
default as the machine name. This situation is very insecure and leads a
hacker right to your wireless workstation. That is why it is very important
to use a nonstandard means of identification for each wireless
workstation so that a hacker cannot know which machine is which; the
administrator is the only one who truly knows. This adds a level of privacy
that also acts as a small security mechanism; you should not give
away too much information about your network to anyone who doesn’t
have a need to know!

Media connection events Some of the items that hackers look for in
any open wireless network involve the way in which the wireless NIC
supports media sense. An event occurs whenever the media connects
with a new access point. In fact, a disconnect event is not even necessary
unless the NIC has totally lost its connectivity to the wireless router.
Note that any connection event indicates to the transport layer that it
should be aware that there might be a transition from one subnet to
another.
