Wireless networking is a topic you are sure to be tested on when taking the A+ Exam. You are responsible for knowing the wireless standards and the common security steps you should take to help secure a wireless network.

Wireless standards

Standard	Description
802.11a	Runs at the 5 GHz frequency range and has a speed of 54 Mbps.
802.11b	Runs at the 2.4 GHz frequency range and has a speed of 11 Mbps.
802.11g	Runs at the 2.4 GHz frequency range and has a speed of 54 Mbps.
802.11n	Runs at the 2.4 GHz or 5 GHz frequency range and has a practical speed of approximately 150 Mbps.
802.11ac	Runs at the 2.4 GHz or 5 GHz frequency range and has a speed of potentially 866 Mbps or more.

Wireless security

Feature	Description
MAC Filtering	You can control which clients can connect to the wireless network by their MAC address. To do this, simply enable MAC address filtering and then add the MAC address of any authorized devices.
Change SSID	Change the SSID of your wireless network so that it is not so obvious. Clients will need to know the SSID in order to connect.
Disable SSID Broadcasting	After changing the SSID, disable SSID broadcasting, which allows you to hide your wireless network from clients.
Enable WPA2	Enable WPA2 as the encryption protocol as it is the more secure protocol of WPA2, WPA, and finally WEP. Ensure that you use a complex key (mix of letters, numbers, and case) when setting the key.
Set Admin Password	Be sure to set an administrator password for your device so others cannot connect to it and change the settings.
