PSK
(Pre-Shared Key)
Authentication mode of WPA used in SOHO environments.
The key value (or pass-phrase) is used for network
authentication only (not data encryption). It does not use a
RADIUS server like the other modes, but uses a shared key
to provide the initial authentication with the access point or
host.
RADIUS (Remote
Authentication Dial-
In Server)
This is an authentication server, such as the Cisco® ACS,
Microsoft® IAS, etc.
RARP or
Reverse Address
Resolution Protocol
One of the available boot methods. The device sends an
RARP request and the RARP server responds with an IP
address. The device knows its MAC address and the
server responds with the IP address for it.
Relative
Pathname
The file or directory location on the user’s system relative
to the user’s current location on the system (what directory
the user is currently in). For example, mpcl
toolbox\9855.phu
Router Any device that forwards data along networks. Routers are
located at gateways.
Shared
Authentication
The access point sends an unencrypted challenge text
string to any device attempting to communicate with it. The
device requesting authentication encrypts the challenge
text and sends it back to the access point. If the challenge
text is encrypted correctly, the access point allows the
requesting device to authenticate. Both the unencrypted
challenge and the encrypted challenge can be monitored;
however, this leaves the access point open to attack.
Because of this weakness, shared key authentication can
be less secure than open authentication.
Signal Strength A percentage (1 to 100) of the connection between the
device and access point. If the signal strength is 0, there
is no connection with the access point; 30 or less indicates
you may be experiencing interference or close to being out
of access point range, and below 50, printing performance
could be affected. To improve the signal strength, try
moving the printer closer to the access point and away
from other radio devices such as Bluetooth® wireless
devices, microwave ovens, or 2.4-GHz cordless phones.
Speed or
Transmit Rate
Sets the maximum rate of communication between the
devices on the network. It is also called transmit rate. The
speeds are in megabits per second (Mbps) and include: 1,
2, 5.5, 11, 12, 18, 24, 36, 48, and 54.
