Summary Wireless LANs use standards such as

IEEE 802.11a

IEEE 802.11b

IEEE 802.11g

IEEE 802.11n

Basic Service set–Mobile clients use a single access point for connectivity

Extended service set–Multiple access point that share an SSID

Summary WLAN security practices/methods include

–MAC address filtering

–SSID making

–Implementing WPA2

Configuration of wireless NIC and access point–Configure both of them the same way

•SSID

–Ensure that the latest firmware is installed

Troubleshooting WLANs include doing the following:–Check channel setting

–Check for interference
