3.2.1 Status and Information
On this screen, users can see the general information of the Access Point including
Alias Name, Firmware Version, ESSID, Channel Number, Status, IP Address, MAC
Address, etc.
3.2.2 Wireless Setting
This Access Point supports AP, Station, Bridge, WDS and Universal Repeater modes.
‘AP Mode’ provides pure access point function. The simplest way to build up a
wireless LAN is to use ‘AP Mode’. ‘Station Mode’ is used to let a network device
with only wired Ethernet function to have wireless LAN communication capability. It
provides both Ad Hoc and Infrastructure modes for the “Station Mode”. With
“Station-Ad Hoc mode”, it can allow user’s network device to join a wireless LAN
with peer-to-peer communication. With ‘Station-Infrastructure mode’, it can allow
network device join a wireless LAN through an access point. ‘AP Bridge Mode’
provides the function to bridge more than 2 wired Ethernet networks together by
wireless LAN.

13
Users can use two access points with ‘AP Bridge-Point to Point mode’ to connect two
wired Ethernet networks together. If users want to bridge more than two wired
Ethernet networks together, use multiple access points with “AP Bridge-Point to
Multi-Point mode”. An access point with “AP Bridge-Point to Point mode” or “AP
Bridge-Point to Multi-Point mode” can only be used to bridge wired Ethernet
networks together. It can’t accept connection from other wireless station at the same
time. If users want an access point to bridge wired Ethernet network and provide
connection service for other wireless station, it is necessary to set the access point to
“AP Bridge-WDS mode”. Simply speaking, ‘AP Bridge-WDS mode’ function is the
combination of ‘AP mode’ and ‘AP Bridge-Point to Multi-Point mode’.
“Universal Repeater Mode” provides the function to act as AP client and AP at the
same time. It can use AP client function to connect to a Root AP and use AP function
to service all wireless stations within its coverage. All stations within the coverage of
this access point can be bridged to the Root AP. “Universal Repeater Mode” is very
convenient to extend the coverage of wireless network.

AP client and AP at the same time. It can use AP client function to connect to a Root
AP and use AP function to service all wireless stations.

Parameter Description
ESSID The ESSID (up to 31 printable ASCII characters) is the unique name
identified in a WLAN. The ID prevents the unintentional merging of two
co-located WLANs. Please make sure that the ESSID of all stations in the
same WLAN network are identical. The default ESSID is ‘default’. Users
should assign ESSID in ‘AP mode’, ‘Station-Ad Hoc mode’, ‘Station-
Infrastructure mode’, ‘AP Bridge-WDS mode’ and ‘Universal Repeater
mode’.
Band It allows user to set the AP to fix at 802.11b or 802.11g mode. It can also
select B+G mode to allow the AP select 802.11b and 802.11g connection
automatically.
Channel Number Select the appropriate channel from the list provided to correspond with
user’s network settings. Channels will differ from country to country.
Channel 1-11 (North America)
Channel 1-14 (Japan)
Channel 1-13 (Europe)
There are 14 channels available.
Users should assign Channel Number in ‘AP mode’, ‘Station-Ad Hoc
mode’, ‘AP Bridge-Point to Point mode’, ‘AP Bridge-Point to Multi-Point
mode’, ‘AP Bridge-WDS mode’ and ‘Universal Repeater mode’.
MAC Address If users want to bridge more than one wired Ethernet networks together
with wireless LAN, it is necessary to set the access point to either “AP
Bridge-Point to Point mode”, “AP Bridge-Point to Multi-Point mode” or
“AP Bridge-WDS mode”. Users have to enter the MAC addresses of other
access points that join to the bridging work.
WLAN MAC In “Station-Ad Hoc mode”, “Station-Infrastructure mode” and “Universal
Repeater mode”, this device needs a WLAN MAC address to act as a
station to connect to other peer or access point. Users also can click <Clone
MAC> button to let this device copy the MAC address of the PC used to
configure this device.
Root AP SSID In “Universal Repeater mode”, this device can act as a station to connect to
a Root AP. Users should assign the SSID of the Root AP in this section.

Set Security In “AP Bridge-Point to Point mode”, “AP Bridge-Point to Multi-Point
mode” and “AP Bridge-WDS mode”, users can click <Set Security> to add
encryption for the communication between the bridged access points. This
can protect the wireless network.
Associated Clients Click <Show Active Clients> button for access to “Active Wireless Client
Table”. It contains the status of all active wireless stations that are
connecting to the access point.
Wireless Site Survey When access point is used as a wireless station for wired network device to
have wireless capability, it is necessary to associate it with a working
access point. Click <Select Site Survey> button, then a “Wireless Site
Survey Table” will pop up. It will list all available access points nearby.
Users can select one access point in the table and it will join wireless LAN
through this access point.
Click <Apply> button at the bottom of the screen to save the configurations.
Set Security
“Set Security” let you setup the wireless security for the data transmission between
the bridged access points in “AP Bridge-Point to Point mode”, “AP Bridge-Point to
Multi-Point mode” or “AP Bridge-WDS mode”. It provides “WEP 64bits”, “WEP
128bits”, “WPA (TKIP)”, “WPA2 (AES)” encryption methods.
