Step 4
Select one of the following WEP key entry methods:
•
Hexadecimal (0-9, A-F)—Specifies that the WEP key will be entered in hexadecimal characters,
which include 0-9, A-F, and a-f.
•
ASCII Text—Specifies that the WEP key will be entered in ASCII text, which includes alpha
characters, numbers, and punctuation marks.
Note
ASCII text WEP keys are not supported on the Cisco Aironet 1200 Series Access Points, so
you must select the Hexadecimal (0-9, A-F) option if you are planning to use your client
adapter with these access points.
Step 5
For the static WEP key that you are entering (1, 2, 3, or 4), select a WEP key size of 40 or 128 on the
right side of the screen. 128-bit client adapters can use 40- or 128-bit keys, but 40-bit adapters can use
only 40-bit keys. If 128 bit is not supported by the client adapter, this option is unavailable.
Step 6
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 must contain the following number of characters:
–
10 hexadecimal characters or 5 ASCII text characters for 40-bit keys
Example: 5A5A313859 (hexadecimal) or ZZ18Y (ASCII)
–
26 hexadecimal characters or 13 ASCII text characters for 128-bit keys
Example: 5A583135333554595549333534 (hexadecimal) or ZX1535TYUI354 (ASCII)
Note
You must enter hexadecimal characters for 5-GHz client adapters if these adapters will be
used with Cisco Aironet 1200 Series Access Points.
•
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.
