Without adequate protection, a wireless LAN is susceptible to access by unauthorized
users. As such, XPress DR+W features the WPA security standard, WPA2 based on
IEEE 802.11i. WEP is provided for backwards compatibility and interaction with older
devices.
To modify WLAN settings, select 4 WLAN from the Change Setup menu.
Topology
Select Infrastructure (ESS) mode or Adhoc (IBSS) mode. Infrastructure mode
communicates with Access Points. Ad Hoc mode communicates only with other clients.
Topology 0=Infrastructure, 1=Adhoc (0) ? _
Network Name (SSID)
Enter the name of the network to which the XPress DR+W will connect.
Network name (LTRX_IBSS) ? _
Adhoc Network Channel
When Adhoc is selected in the Topology parameter, and the XPress DR+W cannot find
the specified network, it creates one with that name by transmitting a beacon on the
selected channel.
Channel (11) ? _
Only channels allowed in the country for which the XPress DR+W is designated can be
selected. The country displays in the Setup Mode settings overview.
Security
The Security Suite prompt enables you to select the type of security. The XPress DR+W
features WEP, WPA and WPA2/802.11i to secure all wireless communication. WPA and
WPA2/802.11i are only available when the topology is Infrastructure.
Notes:
In the WPA and WPA2 modes, the encryption setting denotes the lowest acceptable
encryption method, CCMP > TKIP > WEP. For example, if the unit is configured for
WEP, and the Access Point supports TKIP, the negotiation will result in TKIP being
used. If the unit is configured for TKIP, and the Access Point only supports WEP,
association will fail because the Access Point does not meet the unit's demands.
(CCMP is only available in WPA2 mode.)
Communication between the Access Point and a single wireless device is called
unicast and uses the pairwise encryption method. Communication from the Access
