Security
25
The following table describes the settings. To maintain wireless association, the
settings on clients and all the access points they associate with must
match exactly.
User Access List
If you configure an access point for 128-bit Dynamic Security Link, there must be
at least one entry in the User Access List. The User access List determines which
users are allowed access to the access point. You can define up to 1000 users.
To modify a password, click Change User Password. Select the user name and click
Change user password . In the next page, change the password in the spaces
provided and click OK. If you click Reset, the radio button is cleared and you can
choose another user name.
Setting
Description
No Security (Open System)
No encryption is used. The network communications could be
intercepted by unintended recipients.
40-bit Shared Key (Wi-Fi)
This option encrypts the wireless transmissions to protect
data, but still permits 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
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 AccessPo ints.
■
Hexadecimal keys are sequences of hexadecimal digits
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.
128-bit Shared Encryption Key
Settings.
This option is compatible with 128-bit shared key including
from other vendors, including AirConnect, Agere, and Cisco.
The network administrator sets up encryption keys for the
wireless network and supplies users with an encryption string
or hexadecimal keys. You must set up encryption keys on
both the client and access point.
128-bit Dynamic Security Link
This is the highest level of security, requiring a user name and
password to access the wireless LAN. The user name and
password set up on the access point must match those set up
on the client. Each network session creates a unique,
one-time encryption code. If you choose this type of security,
you must also set up access control as described in User
Access List on page25.
If you check the Require Windows user authentication check
box, clients will be required to enter a user name and
password every time they associate with the network. If you
leave this box unchecked, the system will authenticate clients
based on the access control list and the saved passwords on
the clients.
