2.7 Confirming the Settings of the AP and Client Computers
After you have completed deploying the AP and setting up client computers, you have
to make sure the settings you have made are correct.

2.7.1 Checking if the IEEE 802.11g-Related Settings Work

To check if a wireless client computer can associate with the AP:
1. Launch the configuration/monitoring utility provided by the vendor of the installed
WLAN NIC.
2. Check if the client computer is associated to an access point, and the access point
is the AP.
If the check fails, see Appendix B-1, “Wireless Settings Problems” for troubleshooting.

2.7.2 Checking if the TCP/IP-Related Settings Work

To check if a client computer can access the Internet:
1. Open a Windows Command Prompt window on the client computer.
2. Type ping advap”, where advap is a placeholder for the IP address of the AP. Re-
place it with your real IP address—for example, 192.168.1.254. Then press Enter.
If the AP responds, go to the next step; else, see Appendix B-2, “TCP/IP Settings
Problems” for troubleshooting.
3. Type ping default_gateway”, where default_gateway is a placeholder for the IP
address of the default gateway of the wireless client computer. Then press Enter.
If the gateway responds, go to the next step; else, see Appendix B-2, “TCP/IP Set-
tings Problems” for troubleshooting.
4. Type ping 1st_dns_server”, where 1st_dns_server is a placeholder for the IP ad-
dress of the primary DNS server of the wireless client computer. Then press Enter.
If this DNS server responds, go to the next step; else, see Appendix B-2, “TCP/IP
Settings Problems” for troubleshooting.
