Wireless network setup 40
2. Using a network-connected machine
The wireless network security window appears when the
access point has security settings.
The wireless network security window appears. The window
may differ according to its security mode: WEP, or WPA.
•WEP
Select Open System or Shared Key for the authentication
and enter the WEP security key. Click Next.
WEP (Wired Equivalent Privacy) is a security protocol
preventing unauthorized access to your wireless network.
WEP encrypts the data portion of each packet exchanged
on a wireless network using a 64-bit or 128-bit WEP
encryption key.
•WPA
Enter the WPA shared key and click Next.
WPA authorizes and identifies users based on a secret key
that changes automatically at regular intervals. WPA also
uses TKIP (Temporal Key Integrity Protocol) and AES
(Advanced Encryption Standard) for data encryption.
8 The window shows the wireless network settings and checks
if the settings are correct. Click Next.
• For the DHCP method
If the IP address assignment method is DHCP, check if
DHCP is shown in the window. If it shows Static, click
Change TCP/IP to change the assignment method to
DHCP.
• For the Static method
If the IP address assignment method is Static, check if
Static is shown in the window. If it shows DHCP, click
Change TCP/IP to enter the IP address and other network
configuration values for the machine. Before entering the
IP address for the machine, you must know the computer’s
network configuration information. If the computer is set
to DHCP, you must contact the network administrator to
get the static IP address.
For example:
If the computer’s network information is as shown below:
- IP address: 169.254.133.42
- Subnet Mask: 255.255.0.0
Then, the machine’s network information should be as
follows:
- IP address: 169.254.133.43
