Supported Network Security Options - Lexmark Genesis S815 Quick Reference Manual

If your wireless network is not using security, then you will not have a security key.
Note: If you do not know the SSID of the network that your computer is connected to, then launch the wireless utility
of the computer network adapter and look for the network name. If you cannot find the SSID or the security information
for your network, then see the documentation that came with the access point, or contact your system support person.

Supported network security options

The printer supports three wireless security options: no security, WEP, and WPA/WPA2.
No Security
It is not recommended to use no security at all on a home wireless network. Using no security means that anyone within
range of your wireless network can use your network resources—including Internet access— if your wireless network
is connected to the Internet. The range of your wireless network may extend far beyond the walls of your home, allowing
access to your network from the street or from your neighbors' homes.
WEP
WEP (Wired Equivalent Privacy) is the most basic and the weakest type of wireless security. WEP security relies on a
series of characters called the WEP key.
Every device on the wireless network must use the same WEP key. WEP security can be used on both ad hoc and
infrastructure networks.
A valid WEP key has:
•
Exactly 10 or 26 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9.
or
•
Exactly 5 or 13 ASCII characters. ASCII characters are letters, numbers, punctuation, and symbols found on a
keyboard.
WPA/WPA2
WPA (Wi-Fi Protected Access) and WPA2 (Wi-Fi Protected Access 2) offer stronger wireless network security than WEP.
WPA and WPA2 are similar types of security. WPA2 uses a more complex encryption method and is more secure than
WPA. Both WPA and WPA2 use a series of characters, called the WPA pre-shared key or passphrase, to protect wireless
networks from unauthorized access.
A valid WPA passphrase has:
•
Exactly 64 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9.
or
• From 8 to 63 ASCII characters. ASCII characters are letters, numbers, punctuation, and symbols found on a keyboard.
ASCII characters in a WPA passphrase are case-sensitive.
Every device on the wireless network must use the same WPA passphrase. WPA security is an option only on
infrastructure networks with access points (wireless routers) and network cards that support WPA. Most newer wireless
network equipment also offer WPA2 security as an option.
Note: If your network uses WPA or WPA2 security, then select WPA Personal when you are prompted to select the
type of security your network uses.
