Wireless APInformation 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.

 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 WPAAuthenticator 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.

Access Control Page
If you enable access control, only those clients whose wireless MAC addresses are in the access control
list will be able to connect to your Access Point. When this option is enabled, no wireless clients will be
able to connect if the list contains no entries
