Configuring the Wireless AP

SCALANCE WLC711

3-8 C79000-G8976-C260-03, 07/2012, User Guide, V8.11

The radios are enabled or disabled through the SCALANCE W Wireless Assistant. For more

information, see “Modifying Wireless 802.11n AP W786C/W788C Radio Properties” on page 3-27.

The Unlicensed National Information Infrastructure (U-NII) bands all lie within the 5-GHz band,

designed for short-range, high-speed, wireless networking communication.

The 802.11n AP supports the full range of frequencies available in the 5GHz band:

• 5150 to 5250 MHz - U-NII Low band

• 5250 to 5350 MHz - U-NII Middle Band

• 5470 to 5700 MHz - U-NII Worldwide

• 5725 to 5825 MHz - U-NII High Band

Note:

The Wireless 802.11n AP can achieve link rates of up to 450Mbps. To achieve this level of high link rates,

specific items need to be configured through the SCALANCE W Wireless Assistant. For more information,

see “Achieving High Throughput with the Wireless 802.11n AP” on page 3-37.

Wireless AP International Licensing

The Wireless AP must be configured to operate on the appropriate radio band in accordance with

the regulations of the country in which it is being used.

To configure the appropriate radio band according to the country of operation, use the

SCALANCE IWLAN Controller. For more information, see the manuals of the respective APs.

Wireless AP Default IP Address and First-time Configuration

The Wireless APs are shipped from the factory with a default IP address — 192.168.1.20. The

default IP address simplifies the first-time IP address configuration process for Wireless APs. If

the Wireless AP fails in its discovery process, it returns to its default IP address. This Wireless AP

behavior ensures that only one Wireless AP at a time can use the default IP address on a subnet.

For more information, see “Discovery and Registration Overview” on page 3-9.

The Wireless APs can acquire their IP addresses by one of two methods:

• DHCP assignment — When the Wireless AP is powered on, it attempts to reach the DHCP

server on the network to acquire the IP address. If the Wireless AP is successful in reaching

the DHCP server, the DHCP server assigns an IP address to the Wireless AP.

– If the DHCP assignment is not successful in the first 60 seconds, the Wireless AP returns

to its default IP address.

– The Wireless AP waits for 30 seconds in default IP address mode before again attempting

to acquire an IP address from the DHCP server.

– The process repeats itself until the DHCP assignment is successful, or until an

administrator assigns the Wireless AP an IP address, using static configuration.

Note:

DHCP assignment is the default method for the Wireless AP configuration. DHCP assignment is part of the

discovery process. For more information, see “Discovery and Registration Overview” on page 3-9.

• Static configuration — You can assign a static IP address to the Wireless AP, using the static

configuration option. For more information, see the following section.
