So let's have a look at Wi-Fi protected setup or what you might see as WPX, sure, it's a standard
for the easy and secure establishment of a wireless network that weps is an optional certification program
for Wi-Fi certified products.
So not all wi fi certified products will include some sort of support.
Users will need to look for the Wi-Fi protected set logo or, you know, some equivalent term on the
product to ensure that the product is WPX compatible.
So WPX automatically configures a network name, SS ID and a security key for the access point and the
WPX enabled client devices on a network.
You don't need to know the SS IDs and security key or even the passphrase when connecting waps enabled
devices.
No one can guess or figured out your security key or passphrase because the keys will be randomly generated
so there's no predictable passphrase or long sequences of hexadecimal to enter.
Now, information and network credentials are securely exchanged over the air using the Extensible Authentication
Protocol, or IAP.
That's one of the authentication protocols used in WPA to.
However, yes, there are a few disadvantages.
One, it doesn't support ad hoc mode or network where wireless devices are communicating directly to
each other without an access point.
And all of the Wi-Fi devices on the network must be certified or GPS compatible, otherwise you won't
be able to take advantage of the ease of securing the network in this way.
Now, there are three primary methods used and Wi-Fi protected set up.
There's a pin entry push button configuration and near field communication.
In all Wi-Fi protected setup networks, a unique pin will be required for each device to join the network.
A fixed PIN label or sticker may be placed on a device or a dynamic pin can be generated and then shown
on the devices display.
In any event, the pen is used to make sure the intended device is added to the network being set up,
and it'll help to avoid accidental or even malicious attempts to add unintended devices to that network.
And when some Wi-Fi protected set up networks, the user may connect multiple devices to the network
and then enable data encryption by pushing a button.
The access point, or wireless router, will have a physical button and other devices may have a physical
or even a software base button.
And then during the usually two minute set up period, which follows the push of that button.
Unintended devices could join the network if they are in range, and finally, a near field communication
interface or an NFC can be used to transfer network settings to a new device without requiring manual
entry of its PIN.
Make a note, the NFC method provides strong protection against adding an unintended device to the network.
But I'll leave that as a dot, dot, dot.
