Wireless Information

Important: Keep in mind that NEO will only communicate with access points that are configured with the same SSID.

•Ad Hoc And Infrastructure: If you are using an Infrastructure network – one in which NEOs must pass data through an access point – leave the checkbox next to This is an ad hoc network blank.

If you are using an Ad Hoc network – a network in which NEOs pass data directly to other Ad Hoc devices without an access point – add a checkmark in the checkbox next to This is an ad hoc network to enable Ad Hoc.

•Encryption:WEP (Wired-Equivalent Privacy) encryption prevents others from acciden- tally accessing your network. If you are not using encryption, you can choose Disabled from the dropdown encryption menu. Otherwise, leave this field as is.

AES (Advanced Encryption Standard) is a standard for protecting data through encryp- tion. AES supports key sizes of 128 bits, 192 bits and 256 bits and will serve as a replacement for the Data Encryption Standard (DES), which has a key size of 56 bits. In addition to the increased security that comes with larger key sizes, the AES algorithm is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information.

•Authentication: 802.11 supports four subtypes of network authentication services: Open, Shared, WPA, and WPA-PSK. Under Open authentication, any wireless station can request authentication. The station that needs to authenticate with another wireless station sends an authentication management frame that contains the identity of the sending station. The receiving station then sends back a frame that indicates whether it recognizes the identity of the sending station.
