Using DHCP
To use DHCP, select the radio button Obtain an IP Address automatically. This is the default

• If your PC is already configured, do NOT change the settings on the screen shown in
Figure 63 above, unless advised to do so by your network administrator.
• You can enter the Wireless Access Point's IP address in the Default gateway field and click
OK. Your LAN administrator can advise you of the IP Address they assigned to the Wire-
less Access Point.
• If the DNS Server fields are empty, select Use the following DNS server addresses, and
enter the DNS address or addresses provided by your ISP, then click OK.
Wireless LANs
Wireless networks have their own terms and jargon. It is necessary to understand many of these
terms in order to configure and operate a Wireless LAN.
Modes
Wireless LANs can work in either of two (2) modes:
• Ad-hoc
• Infrastructure
Ad-hoc Mode
Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Sta-
tions (e.g. notebook PCs with wireless cards) communicate directly with each other.
Infrastructure Mode
In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations
(e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations
can then access all LAN resources.
Access Points can only function in "Infrastructure" mode,
and can communicate only with Wireless Stations which are
set to "Infrastructure" mode.
SSID/ESSID
BSS/SSID
A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form
a Basic Service Set (BSS).
