  • Page 56: Wireless Security Overview

    Normally, the NWA570N acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the NWA570N does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess.

  • Page 57: Encryption

    Usually, you should set up the strongest encryption that every device in the wireless network supports. For example, suppose you have a wireless network with the NWA570N and you do not have a RADIUS server. Therefore, there is no authentication. Suppose the wireless network has two devices.
