be rejected similar to the operation of a “firewall”. The 195Eg will hide all the IP addresses connected on the wireless link.
You should use this mode of operation if Model 195Eg is connected directly to the Internet with a static IP address (DSL, T1,
etc.) and you want the wireless clients to access the information through the Model 195Eg (Figure 3). This mode should also
be used for attaching the Model 195Eg to a network where few IP addresses are available or a firewall for the wireless clients
is required.
4. Access Point Repeater. The Access Point Repeater is a unique enhancement of the 802.11g Access Point mode only
available the ESTeem Model 195Eg. The Access Point Repeater can be used with any of the above Access Point modes.
With this repeater feature enabled, the Model 195Eg Access Points do not have to be hardwired together on the same physical
LAN to provide seamless Ethernet communication for roaming 802.11g/b Clients. In addition to greatly extending the Access
Point canopy range, the Model 195Eg will also bridge any Ethernet device or Ethernet network connected to the unit over this
same wireless Ethernet network. This mode gives the user the features of a point to multi-point bridge network but also allows
802.11g/b Client devices or the Model 195Eg in the Client mode to simultaneously roam under the network canopy.
5. Self-Healing Mesh Network. If multiple Access Point Repeater routes are configured to the same destination ESTeem, the
195Eg will create a “self-healing” mesh network by automatically re-routing data through alternate paths to reach its
destination if the primary path is inoperable. The routing and priority of alternate paths is completely user configurable.

Station (802.11g Client) Modes
6. EtherStation Mode. This is a unique feature of the Model 195Eg when used in any Access Point network. When the 195Eg
is configured in the EtherStation Mode and attached to a single Ethernet Device, the Model 195Eg will emulate an 802.11g
PCMCIA wireless card in functionality for communication as an 802.11g client. The 195Eg will seamless roam under the
radio canopy of Access Point and can provide greatly increased range over a Wireless LAN Card for mobile Ethernet devices
such as vehicles, forklifts, cranes, etc (Figures 1-3).
7. Station Router Mode. The Station Router mode will also function as an 802.11g client, similar to EtherStation, but will allow
multiple Ethernet devices to be connected to a single 195Eg (Figure 3). The 195Eg will function as a router between the
wireless client mode and the wired Ethernet devices connected to the Ethernet port. Similar in configuration to the Access
