User's Manual

Instant Wireless - Network USB Adapter User Manual

• Network Address: This is a unique MAC address.

• Operating Mode: Infrastructure or ad-hoc.

• Preamble Type: You can select long or short preamble

• Rate: Select the rate to be used among the following options: 1 Mbps, 2

Mbps, 5.5 Mbps and 11Mbps.

• RTS Threshold: This is the option for the RTS Threshold activation.

• WEP Key: Select one of the four available keys to be used for encryption.

When no key is selected, the encryption is disabled.

• WEP KEY #1 - #4 : Set the value of the WEP key.

For every station participating in a Network the user must select the same

Channel and Rate (1, 2, 5.5, or 11 Mbps) but a different Network Address (MAC

Address). Also the user can set the Fragmentation Threshold (the threshold for

the activation of the fragmentation mechanism), as well as the RTS threshold

(the threshold for the activation of the RTS/CTS mechanism). Also, the user can

select the operating Mode. Two modes are available: Ad-Hoc Mode and

Infrastructure Mode. In Ad-Hoc Mode the wireless stations can directly

communicate, however, in Infrastructure Mode, an Access Point is necessary.

The user can also specify the ESSID (up to 32 characters). The ESSID field is

case sensitive. The user can select long or short preamble as referred in

802.11b specification. Finally, the user can select among four user-defined WEP

keys for encryption e.g. by setting the WEP Key To Use field to 3, the WEP KEY

#3 will be used; by setting it to None, no WEP encryption will be used. Please

keep in mind that the WEP keys must be in HEX and in two characters per byte

formats e.g. if you want the WEP KEY #1 to be 12345, then you must set it as

0102030405.
