CompTIA® Network+ Lab Exercise : Configuring Wep On Client Computers In Wireless Network Environment

6. Configuring WEP on client computers in wireless network environment

Scenario: Configure a wireless WiFi connection on client computers WS3 and WS4 to connect to Access Point AP1 using WEP key "Cert1" and SSID "CertExams". Verify communication between the workstation WS3 and DHCP server (192.168.1.2) using Ping command from WS3 or WS4. Note that AP1 is already configured with appropriate SSID and WEP code (5/13 char long) DHCP is also configured with IP address 192.168.1.2 and subnet mask 255.255.255.0

Instructions:

1. Click AP1 in the network diagram , this will open Access Point configuration window enter ip address 192.168.1.2 in Local IP address box , select 255.255.255.0 as subnet mask from subnet mask drop down , Click option button Enable from DHCP Server and enter starting ip address as 192.168.1.3 and maximum number of DHCP users as 254 .

4. At the command prompt, ping from WS3 to 192.168.1.2 and see that the ping is successful.

WS3:ping 192.168.1.2
Type escape sequence to abort.
Sending 5,100-byte ICMP Echos to  192.168.1.2 ,
Timeout is 2 seconds:
 !!!!! 
Success rate is 100 percent (5/5), round-trip min/avg/max = 6/6/6 ms

5. Repeat steps 3- 4 for WS4

Notes: WEP (short for Wireless Equivalent Privacy) is used to secure wireless LAN. The password could be 5/13 characters long. Necessary conditions to communicate in wireless environment using WEP are:

1. IP address, subnet mask, and default gateway are configured properly

2. SSID and WEP password are configured properly.
