This check box allows users to enable or disable WEP feature. While WEP is

disabled, all the other fields on this “Encryption” page are disabled too. A set of

four keys needs to be created in the default-key scheme.

Default WEP Key to Use

Select the key to be used as the default key. Data transmissions are always

encrypted using the default key. The other keys can only be used to decrypt

received data.

Deny unencrypted data:

Check this field when the WEP is enabled to deny unencrypted data. This feature

enables the adapter to drop all unencrypted packets received.

Authentication

Three options are available: ‘Open’, ‘Shared Key’, and ‘Both’. 'Open' allows

anyone to authenticate to this access point. 'Shared key' allows only stations that

know the key(s) to authenticate. 'Both' allows a station to use either mode.

WEP key length:

The 64-bit encryption is currently the 802.11 standard. The 128-bit encryption is

supported by equipment from a limited number of vendors. Note that the “user-

controlled” portion of the 64-bit encryption is just 40 bits (10 Hex digits) and that

for the 128-bit encryption is just 104 bits (26 Hex digits)—3-bytes of the

encryption key are internal to the encryption algorithm.

WEP key 1/ 2/ 3/ 4:

The keys allows hex number inputs with varying length depending on the type of

WEP being enabled i.e. 64 or128bit WEP

Advance

On this page (Figure 4) you can configure the advanced 802.11g settings such

as Bridging, advance Wireless settings, and Firmware upgrade option.

1. Bridging

To activate the Bridging mode, the user needs to select WLAN card option

allowing multiple clients connecting to an ACR-201-G unit. If Ethernet

client option is selected, the ACR-201-G unit can connect to only a single

client.

2. Advance Wireless

Fragmentation threshold

Transmitted wireless packets larger than this size will be fragmented to

maintain performance in noisy wireless networks. In the presence of

hostile RF environment, such as interference, frames longer than this

threshold numbers in bytes are divided prior to transmission into one or

more fragments equal in length to the fragmentation threshold. The default

value is set at 2346 bytes. The maximum 802.11 data frame size, such
