Click an interface on the Wireless Interfaces screen to open its Wireless Settings screen.

Figure 4-13: The Wireless Settings screen.

Use this screen to configure the following information for the selected wireless interface:

  • ESSIDi: The network name for the wireless LANi. All connected devices should use this same name.

  • Mode: Specifies the mode that this wireless interface should operate in. When set to Master, this interface acts as an access pointi. When set to Ad-hoci, the interface opens a channel to use for communications. When set to Managed, users on connected devices must enter the correct SSID to connect.

  • Channel: Which channel to use; all connected devices need to use the same channel. If you experience interference, switch to another channel.

  • Transmit Power: The power out of the radio transmitter, in dBMs. The range of appropriate values in dependent on the card. Checking the Auto box specifies that the radio is to determine its own transmitter levels.

  • Disable SSID Broadcast: Specifies whether the ESSID is broadcast to wireless clients searching for a router. By default, this setting is cleared, which means that the router broadcasts the ESSID for wireless clients to find.

  • Protocol: Fix the wireless device into a protocol mode given the choices of a-only, g-only, b-only, b and g, auto.  These options are highly dependent on the wireless device.
  • Frag Threshold: When the link is very poor links and you experience a lot of packet loss, set a small fragthreshold. Then the damaged frames will smaller when they have to be retransmitted. The overhead for each packet is greater such that a more typical network connection and the fragthreshold at the maximum value (default).

  • Long Distance: This is used to enhance long distance connections and account for long acknowledgement delays. This option is highly dependent on the wireless device.
  • RTSi/CTS Threshold: On a heavily loaded network with lots of collisions, you can use the RTS/CTS Threshold to avoids collisions at the cost of an extra administrative packet for each data packet. Only use this parameter with large packets.

  • Turbo Mode: A double speed variant called turbo mode which uses two or more channels. This option is highly dependent on the wireless device.
  • Encryptioni Methods: Select an encryption method which will open additional parameters for the selected method.
