Using Static WEP
Step 5
Obtain the static WEP key from your system administrator and enter it in the blank field for the key you
are creating. Follow the guidelines below to enter a new static WEP key:
•
WEP keys can consist of the following hexadecimal characters: 0-9, A-F, and a-f.
•
WEP keys must contain the following number of characters:
–
10 hexadecimal characters for 40-bit keys
Example: 12345abcde
–
26 hexadecimal characters for 128-bit keys
Example: AB34CD78EFab01cd23ef456789
•
Your client adapter’s WEP key must match the WEP key used by the access point (in infrastructure
mode) or clients (in ad hoc mode) with which you are planning to communicate.
•
When setting more than one WEP key, the keys must be assigned to the same WEP key numbers for
all devices. For example, WEP key 2 must be WEP key number 2 on all devices. When multiple
WEP keys are set, they must be in the same order on all devices.
Note
After you enter a WEP key, you can write over it, but you cannot edit or delete it.

key can be selected as the transmit key.
