8.6 Wireless (Wi-Fi)
The Wireless (Wi-Fi) sub-menu displays the number of wireless
clients that are connected to the router, the MAC address of each
system connecting wirelessly, and the IP address of each system
connecting wirelessly. Control buttons allow the administrator to
allow or deny access for each of the listed computers. If
Require
User Login
has not been enabled (
Basic → Wizard
sub-menu),
then the control buttons are not available on this submenu.
8.6.1
Number of Wireless Clients
This lists the client computers that are currently connected to the
WLAN access point.
MAC Address.
The Ethernet ID (MAC address) of the wireless
client.
IP Address.
The LAN-side IP address of the client.
Mode.
The transmission standard being used by the client. Values
are 802.11a, 802.11b, 802.11g, or 802.11n.
Rate.
The actual transmission rate of the client in megabits per
second.
Signal.
This is a relative measure of signal quality. The value is
expressed as a percentage of theoretical best quality. Signal quality
can be reduced by distance, by interference from other radio-
frequency sources (such as cordless telephones or neighboring
wireless networks), and by obstacles between the router and the
wireless device.
If
Require User Login
is enabled then you can also control internet
access privileges for the attached wireless clients.

8.6.2
Clients Allowed Access to the Internet
The control icons allow the administrator to grant access to the client
computers. Access grants provide the same access as if a client went
through the user login.
Client
allowed
temporarily.
Will
have
access
until
disconnected from the Wi-Fi network
Client allowed permanently. Same as the
Remember Me
function in the user login process. Will have access each time connected to the Wi-Fi network.
Client is not allowed. This client computer is denied access to the Wi-Fi network.
8.6.3
Remembered Clients
Once a Wi-Fi client has successfully logged into the Internet access side of the router, the MB
R1200 can “remember” that Wi
-Fi client by
remembering its MAC address, eliminating the need to login each time. NOTE: Remembered Clients are “forgotten” if you reset t
he MBR1200 to
its factory default.

8.7 WISH Sessions
The WISH Sessions sub-menu displays full details of active local wireless
sessions through your router when WISH has been enabled. A WISH session is
a conversation between a program or application on a wirelessly connected
LAN-side computer and another computer, however connected.
Originator.
The IP address and, where appropriate, port number of the
computer that originated a network connection.
Target.
The IP address and, where appropriate, port number of the computer to
which a network connection has been made.
Protocol.
The communications protocol used for the conversation.
State.
State for sessions that use the TCP protocol.
NO: None -- This entry is used as a placeholder for a future connection
that may occur.
SS: SYN Sent -- One of the systems is attempting to start a connection.
EST: Established -- the connection is passing data.
FW: FIN Wait -- The client system has requested that the connection be stopped.
CW: Close Wait -- the server system has requested that the connection be stopped.
TW: Time Wait -- Waiting for a short time while a connection that was in FIN Wait is fully closed.
LA: Last ACK -- Waiting for a short time while a connection that was in Close Wait is fully closed.
CL: Closed -- The connection is no longer active but the session is being tracked in case there are any retransmitted packets still pending.
Priority.
The priority of the message flow is entered here. Four priorities are defined:
BK: Background (least urgent).
BE: Best Effort.
VI: Video.
VO: Voice (most urgent).
Time Out.
The number of seconds of idle time until the router considers the session terminated. The initial value of Time Out depends on the type
and state of the connection.
300 seconds. UDP connections.
240 seconds. Reset or closed TCP connections. The connection does not close instantly so that lingering packets can pass or the
connection can be re-established.
7800 seconds. Established or closing TCP connections.

9 GLOSSARY
802.11
A family of specifications for wireless local area networks (WLANs)
developed by a working group of the Institute of Electrical and
Electronics Engineers (IEEE).
Access Control List
ACL. This is a database of network devices that are allowed to
access resources on the network.
Access Point
AP. Device that allows wireless clients to connect to it and access
the network.
ActiveX
A Microsoft specification for the interaction of software components.
Ad-hoc network
Peer-to-Peer network between wireless clients.
Address Resolution Protocol
ARP. Used to map MAC addresses to IP addresses so that
conversions can be made in both directions.
ADSL
Asymmetric Digital Subscriber Line.
Advanced Encryption Standard
AES. Government encryption standard.
Alphanumeric
Characters A-Z and 0-9.
Antenna
Used to transmit and receive RF signals.
AppleTalk
A set of Local Area Network protocols developed by Apple for their
computer systems.
AppleTalk Address Resolution Protocol
AARP. Used to map the MAC addresses of Apple computers to their
AppleTalk network addresses, so that conversions can be made in
both directions.
Application layer
7th Layer of the OSI model. Provides services to applications to
ensure that they can communicate properly with other applications
on a network.
ASCII
American Standard Code for Information Interchange. This system of
characters is most commonly used for text files.
Attenuation
The loss in strength of digital and analog signals. The loss is greater
when the signal is being transmitted over long distances.
Authentication
To provide credentials, like a Password, in order to verify that the
person or device is really who they are claiming to be.
Automatic Private IP Addressing
APIPA. An IP address that a Windows computer will assign itself
when it is configured to obtain an IP address automatically but no
DHCP server is available on the network.
Backward Compatible
The ability for new devices to communicate and interact with older
legacy devices to guarantee interoperability.
