WLAN Settings
Without adequate protection, a wireless LAN is susceptible to access by
unauthorized users. As such, MatchPort features the WPA security standard, based
on IEEE802.11i and IEEE802.1X. WEP provides for backwards compatibility and
interaction with older devices.
When in WPA and WPA2-PERSONAL modes, the encryption setting denotes the
lowest acceptable encryption method. CCMP is higher than TKIP and TKIP is higher
than WEP. For example, if the MatchPort is configured for WEP and the access point
supports TKIP, the negotiation results the use of TKIP. If the MatchPort is configured
for TKIP and the access point supports only WEP, the association will fail since the
access point does not meet the MatchPort’s requirements.
Unicast communication occurs between the access point and a single wireless
device. It uses the pairwise encryption method. Multicast communication occurs
between the access point and multiple wireless devices. It uses the group encryption
method. The group encryption for all wireless devices communicating with the same
access point must be equal to receive broadcast and multicast messages. If any
device is WEP-only (no support for WPA), set the encryption to TKIP+WEP. To use
higher security with the MatchPort than other devices connecting to the same access
point, use a group encryption lower than the pairwise encryption.
Note: Due to regulations, the country-specific setting has been removed from the
setup menu and Web-Manager. However, we provide a separate utility for changing
the Country/Zone setting. The utility is called SetZone and is included in the
MatchPort package. It is also available for download from the Lantronix web site.
The syntax is SetZone <IP address> [<zone abbreviation>]
Leaving the zone blank causes the utility to report the current setting only. Following
are valid zone abbreviations. These settings are consistent with IEEE802.11b/g
zones:
US=United States
CA=Canada
FR=France
SP=Spain
JP=Japan
OT=Others, such as Europe (excluding
France), Asia, Africa, and Australia
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. Adhoc mode communicates only with other
clients.
