INTRODUCTION TO WIRELESS NETWORKING
This section describes Toshiba's implementation of the Cisco Aironet
350 Series Workgroup Bridge AIR-WGB35x and Cisco Aironet 350
PCI 802.11b wireless Network Interface Card (NIC).
Architecture
The wireless Workgroup Bridge and PCI NIC support network
protocols such as TCP/IP, IPX/SPX, NetBeui, and AppleTalk.
Wireless Network Usage Modes
The controller supports the following four usage modes:
nWired Ethernet LAN - To use the embedded Ethernet LAN, all
protocols should be unbound from the Cisco wireless NIC.
nWireless LAN using AIR-WGB35x - To use the Cisco wireless
Workgroup Bridge, all protocols should be unbound from the Cisco
wireless NIC. The Workgroup Bridge must not be used together with
the wireless NIC.
nWireless LAN using AIR-PCI35x - To use the Cisco wireless
card, all protocols should be unbound from the embedded Ethernet
NIC. Either the Infrastructure or Ad Hoc network type can be used.
nWired Ethernet LAN and peer-to-peer wireless - The embedded
Ethernet LAN NIC can be used to connect to the LAN while the
Cisco wireless NIC is used to communicate with another client who
is not on the network. In this peer-to-peer scenario, all protocols can
be bound to both NICs simultaneously and the wireless NIC must be
configured for the Ad Hoc network type.
Wireless Configuration
Changing the wireless settings does not require rebooting the
controller. This includes changing from one Access Point (AP) to
another by changing SSID. However, if the Access Points are
connected to different networks, a reboot is necessary.
The wireless operation mode can be categorized into two modes,
Infrastructure and Ad Hoc. Infrastructure is used to connect to a
wired Ethernet network through a specified Access Point. Ad Hoc is
used to set up small network between two or more devices. The
802.11b standard specifies a security method called Wireless Enable
Privacy (WEP). This WEP security will restrict unauthorized client to
access the wireless network.
