Advanced View: Configuring Appliances

Using Your Appliance 121

The following status information can be observed in the Wireless Status tab of the Edit Network Interface

pane: Link Status, Link Quality, Like Rating, Link Speed, Link Frequency and WAP MAC.

When you are finished editing the network interface settings, click OK to save any changes to the

appliance. Click Cancel to close this window without saving any changes.

Mode Determines the wireless communication method to use within

your wireless network. If your wireless network uses Wireless

Access Points (WAPs), select Managed. If your wireless

network does not use WAPs, select Ad-Hoc. If you are unsure

of whether wireless access points are in use in your network,

select Automatic and the adapter will attempt to determine if

WAPs are present and self-determine its mode.

Channel The wireless channel on which the adapter will communicate.

Wireless networking clients and WAPs within an ESS must be

configured with the same ESS ID and the same channel.

Band For wireless adapters that support multiple WiFi

communication bands, specifies the wireless band that the card

will attempt to use for communications. You can select:

Automatic: Searches first for 11a, then 11b, then 11g, and

finally for 11a Turbo. The appliance will use the first band

connection/ESSID match it discovers.

• 11a: Looks for only 802.11a band connections

• 11b: Looks for only 802.11b band connections

• 11g: Looks for only 802.11g band connections

• 11a Turbo: Looks for only proprietary 802.11a band

connection

Encryption Use this drop box to specify Specify the type of encryption that

will be used on the wireless transmissions. You can select

WEP, LEAP, or None.

• If you select WEP, you must also specify whether an ASCII

or Hex WEP Key will be used, as well as the WEP Key value.

• If you select LEAP, you must also specify the LEAP

Username and Password that will be used.

Note: LEAP communications are supported only when used

with Cisco 1200 Series AP 12.01T1 wireless access points.

MTU Specifies the Maximum Transmission Unit, the largest physical

packet size, measured in bytes, that a network can transmit.

Any messages larger than the MTU are divided into smaller

packets before being sent.

Every network has a different MTU, which is set by the

network administrator. Ideally, you want the MTU to be the

same as the smallest MTU of all the networks between your

machine and a message's final destination. Otherwise, if your

messages are larger than one of the intervening MTUs, they

will get broken up (fragmented), which slows down

transmission speeds.
