# Wireless General Settings

You configure wireless local area network (WLAN) access from this page. You can configure changes for the 2.4 GHz and 5 GHz radios. To activate configuration changes that you make to the 2.4 GHz and 5 GHz radios, you must click the Activate Changes button (at the top of the page).

Note: When you click Activate Changes, the security device ends all wireless sessions. Wireless users must reconnect to the security device to continue wireless service.

## Configuring the Country Code

There are four predefined regulatory domains: FCC (US), TELEC (Japan), ETSI (Europe), and WORLD (all countries). You cannot select a country code for the FCC and TELEC domains. If the regulatory domain is set to WORLD or ETSI, you must select a country. If you do not set a country for the WORLD or ETSI domains, a warning message appears, and the wireless interfaces cannot function.

1. If your regulatory domain is WORLD or ETSI, select a country from the available list.

2. Click Apply, and then after you finish making changes to the configuration, click Activate Changes.

## Setting MAC Address Control Access Mode

You can control which wireless clients have access to the network through an access control list (ACL). The ACL identifies clients by their MAC addresses and specifies whether the wireless device allows or denies access for each address. The ACL settings apply globally to all SSIDs. You can set the device to operate in one of three ACL access modes:

- Disabled: The wireless device does not filter any MAC addresses. This is the default mode.

- Enabled: The wireless device allows access to all hosts except those marked with a Deny action.

- Strict: The wireless device denies access to all hosts except those marked with an Allow action.

1. Select the appropriate access mode from the MAC Address Access Control list.

2. Click Apply, and after you finish making changes to the configuration, click Activate Changes.

## Configuring the 2.4 GHz or 5 GHz Transceiver (WLAN0)

1. To configure the following options for the 2.4 GHz transceiver, select or check the following:

Antenna Diversity: Antenna A or antenna B, whichever has the stronger signal, is used when diversity (default) is selected. To use an external unidirectional antenna, you can specify antenna A or antenna B (labeled on the security device).

Operation mode: You can enable exclusively 802.11b or 802.11g, both 802.11b and 802.11g, or turbo mode.

Channel: You can select auto (default), which enables the security device to select a channel, or you can set a channel between 1 and 11.

Current Channel (not configurable): The channel that the security device is currently configured to use.

Transmit Power: You can select a transmit power to be Full, Half, Quarter, Eighth, or Minimum (of maximum transmit power, whose value varies, depending on the country in which the security device is located).

Transmit Data Rate: You can specify the minimum data transmit rate in Mbps. The available data transmit rates depend on the radio type. By default, this option is set to auto, which uses the best rate first and then automatically falls back to the next rate if transmission fails.

XR Support: You can enable XR (eXtended Range), which provides increased coverage at a lower data transmission rate. By default, this option is disabled.

Super-G Mode: You can enable Super G, which can increase user data throughput rate up to 4 Mbps for 802.11a and 802.11g clients. By default, this option is disabled.

Extended Channel Mode (available only for 2.4 GHz radio): For regulatory domains that allow extended channel mode, you can enable the security device to use channels 12 and 13.

2. Click Apply, and then after you finish making changes to the entire WLAN configuration, click Activate Changes.
