the TKIP and IEEE 802.1x dynamic key exchange mechanisms are enabled. The
SMC2585W-G is highly secured in this mode.
In the above security modes, a back-end RADIUS (Remote Authentication Dial-In User Ser-
vice) server is needed if IEEE 802.1x functionality is enabled.
According to the IEEE 802.11 standard, WEP can be used for authentication and data en-
cryption. Normally, Shared Key authentication is used if WEP data encryption is enabled. In
rare cases, Open System authentication may be used when WEP data encryption is enabled.
The
Authentication algorithm
setting is provided for better compatibility with wireless client
computers with various WLAN network adapters. There are three options available, including
Open System, Shared Key, and Auto.
When WEP is enabled by a security mode, the
Key length
can be specified to be
64 Bits
or
128 Bits
. The
Selected key
setting specifies the key to be used as a send-key for encrypt-
ing traffic from the local device side to the remote device side. All 4 WEP keys are used as
receive-keys to decrypt traffic from the remote device side to the local device side.
NOTE:
Each field of a WEP key setting is a hex-decimal number from 0-9, A-F. For exam-
ple, when the security mode is
Static WEP
and the key length is
64 Bits
, you could set Key
1 to “00012E3ADF”.
3.5.2.2. MAC-Address-Based Access Control
Fig. 46. MAC-address-based access control settings.
With
MAC-Address-Based Access Control
, you can specify the wireless clients that are
permitted or not permitted to associate with the SMC2585W-G. When the table type is set to
inclusive, entries in the table are permitted to associate with the SMC2585W-G. When the
table type is set to exclusive, entries in the table are not permitted to associate with the
SMC2585W-G.
NOTE:
MAC-address-based access control is only available when the SMC2585W-G is in
AP mode.
To deny wireless clients’ access to the wireless network:
1.
Select Enabled from the
Functionality
drop-down list.
2. Set
the
Access control type
to exclusive.
3.
Specify the MAC address of a wireless client to be denied access, and then click
Add
.
4.
Repeat Step 3 for each other wireless client.
