Configuration 36
6. Enter one to four global WEP Keys in the fields provided.
• For 64-bit encryption, a WEP Key is 10 hexadecimal digits (0-9 and A-F).
• For 128-bit encryption, a WEP Key is 26 hexadecimal digits (0-9 and A-F).
• For 152-bit encryption, a WEP Key is 32 hexadecimal digits (0-9 and A-F).
7. Select one of the configured keys as the Default Key ; this key is used to encrypt
outgoing broadcast packets.
8. Click Apply to Radio to save the changes.
9. Click the
Reboot
button to restart the Access Point in order for the new settings to
take effect.
Note:
Your wireless client must also support 802.1x and your network’s EAP
authentication type. As of the release of this user’s guide, Microsoft’s
802.1x client solution is limited to Windows XP computers. Refer to the
Harmony 802.11a Network Adapter User’s Guide for details.
Enable Repeat
The Harmony 802.11a Access Point can repeat packets between 802.11a clients that
are associated with it. If your network requires that 802.11a clients communicate with
each other, then enable the Access Point’s Repeating parameter. Otherwise, set
Repeating to disabled if you want to prevent 802.11a wireless clients that are
associated with the same Access Point from communicating with each other.
Fragmentation
The Harmony 802.11a Access Point supports an optional feature called Fragmentation.
In harsh radio environments, 802.11a devices may have difficulty transmitting large
packets that exceed a certain size. However, when Fragmentation is enabled, the
802.11a Access Point can break up large packets into a number of smaller packets
(called “fragments”) that can be successfully transmitted to another 802.11a device.
The receiving 802.11a device then reassembles the original packet once it has
received all of the fragments.
You can configure a Harmony 802.11a Access Point to never use Fragmentation or to
fragment only those packets that exceed a certain size. For example, if the
Fragmentation Threshold is set to 1000 Bytes, then a sending radio will fragment any
packet 1000 Bytes or larger before transmitting.
The Fragmentation Threshold supports a range between 256 and 2346 Bytes. If set to
256, then a sending radio will fragment all packets 256 Bytes or larger. If set to 2346,
then a sending radio will fragment only those radio packets that are 2346 Bytes or
larger. By default, Fragmentation is always off.
