Wireless AP Information Page
This page shows the current status and some basic settings of the device.
Wireless Page
This page is used to configure the parameters for wireless LAN clients, which may connect to your
Access Point. Here you may change wireless encryption settings as well as wireless network parameters.
Octopus G Series Wireless AP
TwinMOS Page 15
Visibility Status
When Invisibility is selected, the AP is protected against discovery by wireless sniffers, and all wireless
clients must explicitly know and use the SSID.
Performance Mode
These profiles control a number of settings for overall wireless network usage. Their meanings are
self-explanatory.
SSID
This is the name of the access point on the wireless network. Stations that associate to this access point
may have to know this name.
Channel
This is the radio channel that the access point will operate on. If you experience interference (e.g. lost
connections or slow data transfers) you may need to try different channels to see which is the best.
Transmission Rate
This is the speed at which the access point will transmit data. Normally you should select 'best' here,
although if your wireless network is unusually noisy or quiet you may which to use a fixed low or high
rate.
Save
Click “Save” button to save and implement the new settings.
Cancel
Click “Cancel” button to cancel the settings.
Advanced Settings Page
These settings are only for more technically advanced users who have a sufficient knowledge about
wireless LAN. These settings should not be changed unless you know what effect the changes will have
on your Access Point.
Octopus G Series Wireless AP
TwinMOS Page 16
Maximum associated stations
This the maximum number of wireless stations that can be associated at any one time.
Fragmentation Threshold
The value defines the maximum size of packets: any packet size larger than the value will be fragmented.
If you have decreased this value and experience high packet error rates, you can increase it again, but it
will likely decrease overall network performance. Select a setting within a range of 256 to 2346 bytes.
Minor change is recommended.
RTS Threshold
Minimum packet size required for an RTS (Request To Send). For packets smaller than this threshold,
an RTS is not sent and the packet is transmitted directly to the WLAN. Select a setting within a range of
0 to 2432 bytes. Minor change is recommended
DTIM Interval
This is the number of beacons per DTIM (Delivery Traffic Indication Message),e.g. '1' means send a
DTIM with each beacon, '2' means with every 2nd beacon, etc.
Maximum burst time
This is also known as PRISM Nitro (tm) technology. The technology uses fully standards-compliant
methods that eliminate collisions in mixed-mode networks, while greatly increasing the performance of
both pure 802.11g and mixed 802.11b/g networks. The setting is for the amount of time the radio will be
reserved to send data without requiring an ACK. This number is in units of microseconds. A typical
value would be 1000 microseconds. When this number is zero, bursting is disabled.
Octopus G Series Wireless AP
TwinMOS Page 17
Enable PSM buffer
Turn this on to enable support for stations in power save mode.
Security Page
This page allows you setup the wireless security. Turn on WEP or WPA by using Encryption Keys could
prevent any unauthorized access to your wireless network.
Octopus G Series Wireless AP
TwinMOS Page 18
WPA Configuration
Enable WPA Authenticator to require stations to use high grade encryption and authentication.
PSK pass-phrase
Leave blank if stations will be supplied a key by the 1X Authentication Server. Choose a pass-phrase
between 8 and 63 characters.
WPA Multicast Cipher Type
Currently TKIP is the only permitted setting.
WPA Pairwise Cipher Type
Currently TKIP is the only permitted setting.
WPA Group Key Update Interval
Unit: seconds.
802.1x Configuration
When 802.1X authentication is enabled then the AP will authenticate clients via a remote RADIUS
server.
WEP Configuration
WEP is the wireless encryption standard. To use it you must enter the same key(s) into the access point
and the wireless stations. For 64 bit keys you must enter 10 hex digits into each key box. For 128 bit
keys you must enter 26 hex digits into each key box. A hex digit is either a number from 0 to 9 or a
letter from A to F. If you leave a key box blank then this means a key of all zeros.
Enable WEP
Check this box to enable WEP. For the most secure use of WEP, also select "Deny Unencrypted Data"
and set Authentication to "Shared Key" when WEP is enabled.
WEP Key lengths
You may select the 64-bit or 128-bit to encrypt transmitted data. Larger key length will provide higher
level of security, but the throughput will be lower.
Default WEP key to use
Select the key to be used as the default key. Data transmissions are always encrypted using the default
key. The other keys can only be used to decrypt received data.
Deny unencrypted data
Select this to require peers to use encryption.This is only effective when WEP is enabled.
Authentication
This setting has to be consistent with the wireless devices, which the adapter intends to connect.
•Open System – No authentication is needed among the wireless devices.
•Shared Key – Only wireless devices using a shared key (WEP Key) are allowed to connecting each
other. Setup the same key as the wireless devices, which the adapter intends to connect.
•Both –allows a station to use either mode.

Glossary
802.1x: The standard for wireless LAN authentication used between an AP and a client. 802.1x with
EAP will initiate key handling.
Ad-Hoc Network: The wireless network based on a peer-to-peer communications session. Also referred
to as AdHoc.
Access Point: Access points are way stations in a wireless LAN that are connected to an Ethernet hub or
server. Users can roam within the range of access points and their wireless device connections are
passed from one access point to the next.
Authentication: Authentication refers to the verification of a transmitted message's integrity.
DHCP: DHCP (Dynamic Host Configuration Protocol) software automatically assigns IP addresses to
client stations logging onto a TCP/IP network, which eliminates the need to manually assign permanent
IP addresses.
DSSS (Direct Sequence Spread Spectrum): Method of spreading a wireless signal into wide frequency
bandwidth.
Dynamic IP Address: An IP address that is automatically assigned to a client station in a TCP/IP
network, typically by a DHCP server.
DNS (Domain Name System): System used to map readable machine names into IP addresses
DTIM: DTIM (Delivery Traffic Indication Message) provides client stations with information on the
next opportunity to monitor for broadcast or multicast messages.
Filter: Filters are schemes, which only allow specified data to be transmitted. For example, the router
can filter specific IP addresses so that users cannot connect to those addresses.
Firmware: Programming inserted into programmable read-only memory, thus becoming a permanent
part of a computing device.
Fragmentation: Refers to the breaking up of data packets during transmis-sion.
Gateway: Gateways are computers that convert protocols enabling different networks, applications, and
operating systems to exchange information.
ISP: An ISP is an organization providing Internet access service via modems, ISDN (Integrated
Services Digital Network), and private lines.
Octopus G Series Wireless AP
TwinMOS Page 25
LAN(Local Area Network): A group of computers and peripheral devices connected to share
resources.
MAC (Medium Access Control) Address: A unique number that distinguishes network cards.
MTU: MTU (Maximum Transmission/Transfer Unit) is the largest packet size that can be sent over a
network. Messages larger than the MTU are divided into smaller packets.
NAT: NAT (Network Address Translation - also known as IP masquerading) enables an organization to
present itself to the Internet with one address. NAT converts the address of each LAN node into one IP
address for the Internet (and vice versa). NAT also provides a certain amount of security by acting as a
firewall by keeping individual IP addresses hidden from the WAN.
Preamble: Preamble refers to the length of a CRC (Cyclic Redundancy Check) block that monitors’
communications between roaming wireless enabled devices and access points.
Protocol: A standard way of exchanging information between computers.
RADIUS (Remote Authentication Dial In User Service): A server that issues authentication key to
clients.
RAM (Random Access Memory): Non-permanent memory.
RIP: RIP (Routing Information Protocol) is a routing protocol that is integrated in the TCP/IP protocol.
RIP finds a route that is based on the smallest number of hops between the source of a packet and its
destination.
Router: Device that can connect individual LANs and remote sites to a server.
Roaming: The ability to use a wireless device while moving from one access point to another without
losing the connection.
RTS: RTS (Request To Send) is a signal sent from the transmitting station to the receiving station
requesting permission to transmit data.
Server: Servers are typically powerful and fast machines that store programs and data. The programs
and data are shared by client machines (workstations) on the network.
Static IP Address: A permanent IP address is assigned to a node in a TCP/IP network. Also known as
global IP.
Subnet Mask: Subnet Masks (SUBNET work masks) are used by IP protocol to direct messages into a
specified network segment (i.e., subnet). A subnet mask is stored in the client machine, server or router
and is compared with an incoming IP ad-dress to determine whether to accept or reject the packet.
SSID: SSID (Service Set Identifier) is a security measure used in WLANs. The SSID is a unique
identifier attached to packets sent over WLANs. This identifier emulates a password when a wireless
device attempts communication on the WLAN. Because an SSID distinguishes WLANS from each other,
Octopus G Series Wireless AP
TwinMOS Page 26
access points and wireless devices trying to connect to a WLAN must use the same SSID.
TCP/IP: TCP/IP (Transmission Control Protocol/Internet Protocol) is the main Internet communications
protocol. The TCP part ensures that data is completely sent and received at the other end. Another part
of the TCP/IP protocol set is UDP, which is used to send data when accuracy and guaranteed packet
delivery are not as important (for example, in real-time video and audio transmission).
TFTP (Trivial File Transfer Protocol): Simple form of FTP (File Transfer Protocol), which Uses UDP
(User Datagram Protocol), rather than TCP/IP for data transport and provides no security features.
TKIP (Temporal Key Integrity Protocol): An encryption method replacing WEP.TKIP uses random
IV and frequent key exchanges.
UDP (User Datagram Protocol): A communication method (protocol) that offers a limited amount of
service when messages are exchanged between computers in a network. UDP is used as an alternative
to TCP/IP.
Uplink: Link to the next level up in a communication hierarchy.
UTP (Unshielded Twisted Pair) cable: Two or more unshielded wires twisted together to form a cable.
Virtual Servers: Virtual servers are client servers (such as Web servers) that share resources with other
virtual servers (i.e., it is not a dedicated server).
WEP (Wired Equivalent Privacy): An encryption method based on 64 or 128bit algorithm.
Web Browser: A software program that allows viewing of web pages.
WLAN: WLANs (Wireless LANs) are local area networks that use wireless communications for
transmitting data. Transmissions are usually in the 2.4 GHz band. WLAN devices do not need to be
lined up for communications like infrared devices. WLAN devices use access points, which are
connected to the wired LAN and provide connectivity to the LAN. The radio frequency of WLAN
devices is strong enough to be transmitted through non-metal walls and objests, and can cover an area up
to a thousand feet. Laptops and notebooks use wireless LAN PCMCIA cards while PCs use plug-in
cards to access the WLAN.
