Configuring Wireless LANs to Capture
3 You can enter up to four separate encryption keys in ASCII format.
Valid ASCII entries include the letters A through Z in either upper- or
lower-case, in addition to the numbers 0 through 9. Entries are
case-sensitive.
Specified keys are interpreted as the following:
 An empty field is equivalent to a setting of None in Hex entry
mode (that is, no encryption is used on the network).
 Five ASCII characters or 0x followed by 10 hex characters is
interpreted as a 40-bit key.
 Thirteen ASCII characters or 0x followed by 26 hex characters is
interpreted as a 128-bit key.
NOTE: The four encryption keys in use on a WEP-encrypted network
are all typically the same length — either 40-bit or 128-bit.
NOTE: Key entries appear as asterisks to preserve their security.

Setting the Security Options
The Security options let you specify whether the Sniffer software should use
the same WEP keys on every channel on the wireless network or different keys
on different channels.
 Enable the Single Key Set option if you would like the Sniffer software
to use the WEP keys specified in the Encryption portion of the 802.11
tab for every channel on the wireless network.
 Enable the Keys Per Channel option if you would like to specify
different sets of WEP keys for different channels on the wireless
network. Use the following procedure to specify different sets of WEP
keys for different channels.
To specify different WEP keys for different channels using the Keys Per
Channel option:
1 Display the Tools > Options > 802.11 tab.
2 Enable the Keys Per Channel option.
