Configuring the SDS using a Web interface Quatech SDS User’s Manual
Step Procedure Description
‰
Step 5 Configure the SSID (network name).
The Service Set Identifier (SSID) is the
name assigned to your wireless network.
All devices on a wireless network must
be configured with the same SSID.
‰
Step 6 Select the Access Mode.
¾ Infrastructure (using the access point)
If using Infrastructure mode,
go to □ Step 8 .
¾ Ad hoc (no access point)
If using Ad hoc mode,
continue with
□ Step 7 .
In Infrastructure mode, an AP bridges
or joins a wireless network (WLAN) to a
wired Ethernet network (LAN).
Ad hoc is a wireless communication
mode that allows all wireless devices
within range of each other to discover
and communicate with one another
without involving central access points.
Devices communicating in ad hoc mode
do so in peer-to-peer fashion. All wireless
adapters on the ad-hoc network must
use the same SSID and the same
channel number.
‰
Step 7 For Ad hoc only, configure the Channel. As with the SSID, devices sharing a
wireless link must be tuned to the same
channel.
Note: The Channel setting is only used in
Ad hoc mode. In Infrastructure mode, the
access point (AP) determines which channel
all devices associated with it must use.
‰
Step 8 Select the wireless security (encryption)
mode.
¾ Open. Continue with □ Step 12.
¾ WEP. Continue with □ Step 10.
¾ WPA-PSK. Continue with □ Step 9.
Note: In Infrastructure mode, the access
point (AP) determines which setting must be
used. In Ad hoc mode, all of the wireless
devices on the ad hoc network must use the
same setting.
Open mode disables encryption.
WEP provides basic encryption
supported by nearly all 802.11 access
points.
WPA-PSK is more robust than WEP. It
is supported by many recently designed
access points.
‰
Step 9 Enter the WPA-PSK Passphrase.
Go to
□ Step 12 .
The passphrase can be as long as 63
characters. The same passphrase must
be used on the access point and on the
SDS.
‰
Step 10 Select the WEP Key Length.
¾ 64 bit
¾ 128 bit
Sets the WEP key length to be used.
Selecting 64 bit activates the top row of
hex number boxes.
Selecting 128 bit activates both rows.
