Chapter 7 Wireless LAN (WLAN) Screens
LAN-Cell 2 User’s Guide
138
The wireless network is the part in the blue circle. In this wireless network, devices A and B
are called wireless clients. The wireless clients use the access point (AP) to interact with other
devices (such as the printer) or with the Internet. Your LAN-Cell is the AP.
Every wireless network must follow these basic guidelines.
• Every wireless client in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentity.
• If two wireless networks overlap, they should use different channels.
Like radio stations or television channels, each wireless network uses a specific channel,
or frequency, to send and receive information.
• Every wireless client in the same wireless network must use security compatible with the
AP.
7.1.1 What You Can Do in the WLAN Screens
• Use the WLAN screen (Section 7.2 on page 139) to configure TCP/IP, DHCP, IP/MAC
binding and NetBIOS settings on the WLAN.
• Use the Static DHCP screen (Section 7.3 on page 141) to configure the IP addresses
assigned to devices in the LAN by DHCP.
• Use the IP Alias screen (Section 7.4 on page 142) to configure IP alias settings on the
LAN-Cell’s LAN ports.
• Use the Port Roles screen (Section 7.5 on page 144) to set a port to be part of the WLAN
and connect an Access Point (AP) to the WLAN interface to extend the LAN-Cell’s
wireless LAN coverage.
7.1.2 What You Need to Know About Wireless LAN
DHCP
Like the LAN, the LAN-Cell can also assign TCP/IP configuration via DHCP to computers
connected to the WLAN ports.
See Section 4.3 on page 83 for more information on DHCP.
IP Alias
IP alias allows you to partition a physical network into different logical networks over the
same Ethernet interface. See Section 4.4 on page 84 for more information on IP alias.
Port Roles
Use port roles to set ports as part of the LAN, DMZ and/or WLAN interface. See Section 4.5
on page 86 for more information on port roles.
