Description
No encryption is used. The network communications could be
intercepted by unintended recipients.
This option encrypts the wireless transmissions to protect
data, but still allows communication among compatible
wireless LAN clients and access points from third-party
manufacturers.
This type of security requires you to set up encryption in one
of the following ways:
An encryption string is a string of characters between 6
I
and 30 characters long. The string can be any combination
of letters and numbers and is case sensitive. The
encryption string can be used only with other
3Com 11 Mbps wireless PC Cards and Access Points.
Hexadecimal keys are sequences of hexadecimal digits
I
arranged into four keys. A hexadecimal digit may be a
letter from A to F or a number from 0 to 9. This type of
encryption is compatible with equipment from other
manufacturers that use Wi-Fi certified 40-bit encryption.
