Configure AP Device Radio Settings

When you configure your WatchGuard AP device, you specify the radio settings, which includes the band, wireless mode, channel, and SSID settings.

To configure the radio settings:

  1. Select Network > Gateway Wireless Controller.
    The Gateway Wireless Controller page appears.
  2. Select the Access Points tab.
    The Access Points list appears.
  3. Select an AP device and click Edit.
    The Edit Access Point dialog box appears.
  4. Configure the radio settings as described in the subsequent sections.

Set the Band and Wireless Mode

WatchGuard AP devices support two wireless bands, 2.4GHz and 5GHz. The 5GHz band provides greater performance than the 2.4GHz band, but is not compatible with all wireless devices. When you specify the band and mode in the radio settings, make sure to select the correct options for the wireless cards in the wireless client devices that connect to the AP device.

The configuration options for each radio depend on the AP device model.

AP100 / AP102

The AP100 and AP102 have one radio, Radio 1. You can configure Radio 1 to use either the 2.4GHz or 5GHz band.

AP200

The AP200 has two single-band radios, Radio 1 and Radio 2.

You configure the settings for each radio separately.

The wireless modes available for each radio depend on the wireless band the radio uses.

The 2.4GHz band supports five wireless modes:

802.11 B/G/N Mixed

This is the default mode in the 2.4 GHz band. This mode enables the radio to connect with devices that use 802.11n, 802.11g, or 802.11b.

802.11 B

This enables the radio to connect only with devices that use 802.11b.

802.11 B/G Mixed

This mode enables the radio to connect with devices that use 802.11b or 802.11g.

802.11 G

This enables the radio to connect only with devices that use 802.11g.

802.11 N only

This enables the radio to connect only with devices that use 802.11n.

The 5GHz band supports three wireless modes:

802.11 A/N Mixed

This is the default mode in the 5GHz band. This mode enables the radio to connect with devices that use 802.11n or 802.11a.

802.11 A

This enables the radio to connect with devices that use 802.11a

802.11 N only

This enables the radio to connect with devices that use 802.11n.

If you choose a wireless mode that supports mixed 802.11 standards, the overall performance of the radio can decrease. This reduction in performance is caused in part by the backward compatibility settings in mixed modes that enable devices with slower modes to connect to the AP device radio.

Configure the Preferred Channel

When you first pair or add an AP device, the Preferred Channel is set to Auto, and each radio automatically selects an available quiet channel in the band you have chosen.

The location of the AP device affects which channels an AP device radio can use. You configure the location of your AP devices in the Gateway Wireless Controller settings. For more information, see Configure Gateway Wireless Controller Settings.

When you edit an AP device configuration, you can set the preferred channel for each radio. The available channels are determined based on the band, wireless mode, channel HT mode, and the configured location of the AP device.

To set a preferred channel for an AP device radio, select a channel from the Preferred Channel drop-down list.

The AP device attempts to use the preferred channel you select. If there is some reason the preferred channel cannot be used, the AP device automatically selects a different available channel in the configured radio band.

Configure Channel Width Settings

You can configure each radio to use a 20 MHz or 40 MHz channel width. To set the channel width for each radio, configure the Channel HT (High Throughput) Mode.

For each radio, select a setting for the Channel HT Mode:

20MHz

This mode sets the radio to use a 20MHz channel width. This is the default setting.

20/40MHz

This mode is available only when the Preferred Channel is set to Auto. This mode enables the radio to use either a 20MHz or 40MHz channel width, based on the available channels.

40MHz

This mode sets the radio to use 40MHz channel width. This mode assumes that no other 802.11a/b/g access points use the same channel.

If you use a 40MHz channel mode, the Extension Channel controls whether the radio adds the extra 20MHz of channel width above or below the selected channel.

For each radio, select a setting for the Extension Channel:

Upper Channel

Adds the 20MHz channel width above the selected channel.

Lower Channel

Adds the 20MHz channel width below the selected channel.

Set the Data Transfer Rate

For each radio, you can optionally limit the speed at which wireless clients can send data. By default, the data rate is set to Auto, which means that there is no limit.

To set the maximum data transfer rate, select a rate from the Rate drop-down list. The actual client receive (download) rate will be slightly less than this value.

The available rates you can select depend on the wireless mode the radio uses. Rates that start with MCS correspond to the MCS (Modulation and Coding Scheme) index values defined in the IEEE 802.11n-2009 standard.

Each MCS option has two associated rates:

Set the Transmit Power Level

For each radio, you can optionally set the maximum transmit power to limit or expand the transmission distance of your wireless signals. You can set the transmit power between 3dBm to 20dBm, or set the value to Auto. The default (Auto) is 20dBm. The transmit power cannot exceed the regulatory limits set by your region.

To set the transmit power:

From the TX Power drop-down list, select a value.

Select the SSIDs

Each radio can support up to eight SSIDs. You can use the same SSID for more than one radio on one or more AP devices. You can add up to eight SSIDs to each radio.

To add a configured SSID to a radio:

In the SSID list, select the check box adjacent to each SSID you want the radio to use.

If the SSID you want to add is not yet configured, you can add this AP device radio to the SSID when you add the SSID.

For more information, see Configure WatchGuard AP Device SSIDs.
