Configuring Network Profiles
Setting Wireless Encryption
If your wireless network uses WEP encryption, and you have set the Authentication Mode as Open +
WEP or Shared Key + WEP, you must enter an ASCII or hexadecimal WEP Key.
The WEP Keys for the phone must match the WEP Keys assigned to the access point. Cisco Unified
Wireless IP Phone 7921G and Cisco Aironet Access Points support both 40-bit and 128-bit encryption
keys.
WEP Key Formats
You must use one of these formats when setting up a WEP key:
Hexadecimal
For hexadecimal keys, you can use one of the following key sizes:
•
40-bit—You must enter a 10-digit encryption key string that uses the hex digits (0-9 and/or A-F);
or example, ABCD123456.
•
128-bit—You must enter a 26-digit encryption key string that uses the hex digits (0-9 and/or A-F);
or example, AB123456789CD01234567890EF.
ASCII
For ASCII keys, you must enter a character string that uses 0-9, A-Z (upper and lower case), and all
symbols.
•
40-bit—You must enter a 5-character string; for example, GREG5.
•
128-bit—You must enter a 13-character string; for example, GREGSSECRET13.
