Security methods 23
Static WEP
This is the least secure method of protecting wireless transmissions. WEP is provided so you can
support clients that do not support WPA.
Note WEP cannot be used when the radio operating mode supports 802.11n.
Key length
Select one of the following values as the length of the encryption key:
• 64 bits: The key can be 5 ASCII characters or 10 hexadecimal digits.
• 128 b i ts : The key can be 13 ASCII characters or 26 hexadecimal digits.
When encryption is enabled, wireless clients that do not support encryption cannot
communicate with the M210. The same encryption key must be used on the M210 and all
wireless clients.
Key type
Select the format used to specify the encryption key:
• ASCII: ASCII keys are much weaker than carefully chosen hexadecimal keys. You can
include ASCII characters from 32 to 126, inclusive, in the key. However, note that not all
wireless clients support non-alphanumeric characters such as spaces, punctuation, or
special symbols in the key.
• Hex: Your keys should only include the following hexadecimal characters: 0–9, a–f, A–F.
Key 1
Enter a key of the specified format and length. The Quick setup wizard allows you to configure
one key. You can configure additional keys on the Wireless > Communities page.
