WLAN Settings
Without adequate protection, a wireless LAN is susceptible to access by
unauthorized users. As such, WiPort features the WPA security standard, based on
IEEE802.11i and IEEE802.1X. WEP is provided for backwards compatibility and
interaction with older devices.
When in WPA and WPA2 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 WiPort is configured for WEP and the AP supports TKIP,
the negotiation results in the use of TKIP. If the WiPort is configured for TKIP and the
AP supports only WEP, the association will fail because the AP does not meet the
WiPort’s requirements.
Unicast communication occurs between the AP and a single wireless device. It uses
the pairwise encryption method. Multicast communication occurs between the AP
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 in order to receive broadcast and multicast messages. If any device is
WEP-only (i.e. no support for WPA), set the encryption to TKIP+WEP. To use higher
security with the WiPort than other devices connecting to the same AP, 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 WiPort
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
