• Ad hoc mode
A method of communicating
with other client computers,
peer to peer, without an ac-
cess point. The same commu-
nication channel must be
used for all client computers.
• 802.11 Ad hoc mode
A method of communicating
with other client computers,
peer to peer, without an ac-
cess point. The same commu-
nication channel and SSID
must be used for all client
computers.
❖ ❖ ❖ ❖
SSID
Enter the SSID (Service Set Iden-
tifier) you want to use, using up
to 32 characters. The SSID cur-
rently in use appears in paren-
theses.
This information appears if
[ 802.11 Ad hoc mode ] or [ Infra-
structure mode ] is selected in the
[ Communication Mode ] list.
The SSID is an identifier used
when connecting between an
access point and a wireless LAN
client. Only a wireless LAN cli-
ent and an access point that
have the same SSID can com-
municate with each other.
❖ ❖ ❖ ❖
Channel
If [ 802.11 Ad hoc mode ] or [ Ad hoc
mode ] is selected in the [ Commu-
nication Mode ] list, select a com-
munication channel.
The channel is a set radio fre-
quency used for wireless LAN
(IEEE 802.11b). Client comput-
ers using the same channel can
communicate with each other.
❖ ❖ ❖ ❖
WEP Setting
Select whether to enable or dis-
able WEP (Wired Equivalent
Privacy) encryption.
WEP encryption protects wire-
less data communication. To
communicate using WEP, data
from both transmitting and re-
ceiving computers must be set
with the same WEP Key. To en-
able WEP encryption, select
[ En-
able ] in the list, and then enter
the WEP key in the [ WEP Key ]
box.
❖ ❖ ❖ ❖
WEP Key and Confirm WEP Key
The same WEP key must be en-
tered in
[ WEP Key ]
and
[ Confirm
WEP Key ] boxes.
• 64 bit Key
When [ Enable ] is selected in
the [ WEP Setting ] list, enter a
10-digit hexadecimal WEP
key value in
[ WEP Key ] and
[ Confirm WEP Key ] boxes. En-
ter the WEP key value with-
out the prefix “0x.” The value
entered appears as the “*.”
• 128 bit Key
When [ Enable ] is selected in
the [ WEP Setting ] list, enter a
26-digit hexadecimal WEP
key value in
[ WEP Key ] and
[ Confirm WEP Key ] boxes. A
128-bit key provides higher
security than a 64-bit key. En-
ter the WEP key value with-
out the prefix “0x.” The value
entered appears as the “*.”
