Using Static WEP
This section provides instructions for entering new static WEP keys or overwriting existing static WEP
keys.
Entering a New Static WEP Key
Follow these steps to enter a new static WEP key for this profile.
Step 1 Choose None under Network Authentication on the Network Security screen.
Step 2 Choose Static WEP under Data Encryption.
Step 3 Click the Static WEP Keys button. The Static WEP Keys screen appears (see Figure 5-6).

Step 4
Choose 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 choose 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), choose 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.
