Introduction; Network Usage Modes - Toshiba GL-1020 Administrator's Manual

INTRODUCTION

There are two types of wireless networks: Infrastructure and Ad
Hoc.
In the Infrastructure type, a number of base stations, called access
points (AP), are connected to a wired Ethernet network. These
APs can transmit and receive over a radius of up to 100 meters.
Users with wireless client devices such as notebooks access the
network through the nearest AP, and can move around the site
without dropping the connection.
In the Ad Hoc type, two or more devices form a small temporary
network, communicating directly with each other.
The IEEE 802.11b standard for wireless communications
specifies a security method called Wired Equivalent Privacy
(WEP) which restricts unauthorized access to the wireless
network.
The Cisco wireless card supports widely-used network protocols
such as TCP/IP, IPX/SPX, and AppleTalk.

Network Usage Modes

With the Cisco wireless card installed, the controller supports the
following usage modes:
Wired Ethernet LAN
To use the wired Ethernet LAN only, disable the Cisco wireless
card.
Wireless LAN using Cisco NIC
To use the wireless card only, disable the embedded Ethernet
NIC. The wireless card supports both Infrastructure and Ad Hoc
network types.
Wired Ethernet LAN and Wireless LAN
You can use the embedded Ethernet NIC and the Cisco wireless
NIC to connect to the LAN. In this case, you can have all network
protocols enabled on both NICs simultaneously. The wireless
NIC must be configured for the Infrastructure network type.
Wired Ethernet LAN and Peer-to-Peer Wireless
You can use the embedded Ethernet NIC to connect to the LAN
while the Cisco wireless NIC communicates with another client
that is not on the network. In this case, you can have all network
