Configuring Network Profiles Chapter 4 Using the Cisco Unified Wireless IP Phone 7921G Web Pages 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.
