Wireless Settings
Wireless Overview
Wireless networking is supported on EMG models only. The EMG can be configured as a wireless
station (client) or an access point (AP), but not both simultaneously. Both configurations act as a
network interface with a single IP address assigned to it, supporting the same applications that are
accessible over the other network interfaces. The AP is enabled by default with Open security, for
the primary purpose of initial setup and configuration of the EMG (this requires the usual login
credentials to gain access to the EMG UI). Once initial configuration is complete, the AP should be
reconfigured with stronger security settings or disabled.
WiFi Regulatory Domain
The WiFi regulatory domain can be changed on the main Wireless Setting page. Supported
regions are: FCC (United States), IC (Industry Canada), CN (China), JP (Japan), KCC (Korea),
ETSI (Europe without EN 300 440 support), EN440 (Europe with EN 300 440 support), AU
(Australia) and WW (World Mode).
Warning: This is an Advanced Configuration parameter. Each time the region is
changed it is programmed into the radio, which can be done a maximum
of ~10 times; use care when changing the region. There are no visible
counters showing how many times it has been changed. After the tenth
change, the region code remains stuck on the tenth setting
permanently.
Access Point
The EMG access point is enabled by default, with Open security. This allows a wireless device to
connect to the EMG for initial configuration of the EMG, instead of using connections that require a
cabled connection. The default SSID is Lantronix_EMGxxxx , where xxxx is the last 4 characters
of the Ethernet port Eth1 MAC address.
Warning: After logging into the EMG, you should enable AP security and re-
associate with new security settings.
The access point will allow WiFi devices to connect to the EMG and access all functions, similar to
how users on a wired network connect to the EMG via Ethernet ports Eth1 or Eth2. A maximum of
5 clients can connect simultaneously to the access point. A DHCP server will assign IP addresses
to the clients.
The access point supports WPA or WPA2 for security, with CCMP for AES in Counter mode with
CBC-MAC (preferred), TKIP for Temporal Key Integrity Protocol.
Wireless Client
Configuring the EMG to connect to a WLAN network as a client requires a WLAN profile, which is
a set of configuration parameters that will enable the EMG to connect and authenticate to a WLAN
network. The EMG supports up to 4 WLAN profiles, with a priority assigned to each profile. The
matching network with the highest priority value will be selected for the client connection. Profiles
can be created manually by entering the SSID and authentication parameters. Profiles can also be
created with Quick Connect which will scan for wireless networks within range and present a list of
networks; any detected network can be selected and added as a WLAN profile along with the
required authentication information.
The wireless client can connect to a WLAN network using WEP authentication (Open or Shared
with 64 bit or 128 bit encryption), or WPA/WPA2 authentication (PSK or 802.1X/Enterprise with
AES/CCMP or TKIP encryption).
