3. Security Features

Every administrator should set up security on APs. In fact, some vendors, including D-Link and Belkin, have changed the default setup of username admin with a blank password to a setup with a random username and password out of the box. It's still a good idea to enable additional security. Many APs allow for multiple groups of users, so you can set up a separate guest network that allows access to the Internet, but not to local resources such as file servers and printers.

Security standards have become easier to set up and harder to crack over the last few years. The newest standards can automatically exchange keys with new devices on the Wi-Fi network, but may not work as easily with all devices with older operating systems such as Windows XP.

4. Multiple Streams and QoS

When there are dozens or hundreds of devices on the network, with some doing other business-related tasks while others stream recreational videos, it's useful to guarantee that the important applications get sufficient bandwidth. Some to ensure that specific applications or protocols receive the bandwidth they need, while throttling or restricting inessential applications.
